Teaching and Learning

Accreditation period: 2023–2027

A range of suggested learning activities have been provided for each area of study in Units 1–4. It should be noted that the activities included cover a range of the key knowledge and key science skills for each area of study, but not all of them. Some activities could be completed within one class and others could be completed over an extended period. They include learning activities that involve group work, class discussion, practical application of scientific skills and synthesis of knowledge and skills in written responses. Many of the learning activities could be adapted for use in other areas of study or units, or developed into assessment tasks. All are intended to be examples that teachers will use and / or adapt to suit their school context and needs of their own students. Included external links are for teacher reference purposes. They do not constitute VCAA endorsement of the views or materials contained on these sites and teachers should ensure that any information or activities are appropriately adapted to meet the requirements of the VCE Psychology Study Design 2023–2027.

Unit 1: How are behaviour and mental processes shaped?

Area of Study 1: What influences psychological development?

Outcome 1

On completion of this unit the student should be able to discuss complexity of psychological development over the life span, and evaluate ways of understanding and representing psychological development.

To achieve this outcome the student will draw on key knowledge outlined in Area of Study 1 and relevant key science skills on pages 12 and 13 of the study design.

Detailed example 1

Evaluation of the usefulness of mental illness diagnostic tools

Background

The latest version of the Diagnostic and Statistical Manual (DSM 5 TR) was released in 2022. The most recent version of the International Classification of Diseases (ICD 11) also came into effect in 2022. Together they are the most widely used tools by psychologists and psychiatrists to classify and diagnose mental illness.

Aim

To understand the applications, limitations and improvements in diagnostic tools over time.

To improve key science skills including evaluation of systems developed to meet human needs.

Task

Students are required to investigate these diagnostic tools in terms of their usefulness and limitations using the following points as a guide:

  • Summarise the content of the two main diagnostic tools (DSM 5 TR and ICD 11), highlighting the similarities and differences.
  • Outline how they may be of use to mental health professionals to support psychological development and wellbeing.
  • Investigate the process in developing the latest versions: which groups provided input and the key differences and improvements from previous versions including language around gender identity and sexual orientation.
  • Outline how the latest versions ensure more culturally sensitive diagnoses.
  • Explain how high levels of internal and external validity have been achieved over time.

Students may choose to present their findings as a written report or they can use their information to create an interview / news piece and submit their work as a short video.

Detailed example 2

Survey on understanding of neurodiversity

Background

The term neurodiversity has been increasingly used to refer to a range of disorders including Attention Deficit Hyperactivity Disorder (ADHD), Dyscalculia, Autistic Spectrum and Tourette Syndrome. One of the main aims of changing the language around traditional labels is to shift perceptions of these variations to be positive and to support and empower neurodiverse individuals. Neurodiversity Celebration Week was founded in 2018 to encourage understanding, appreciation and inclusivity for all variations in the neurocognitive abilities of the human population. Consider the information about neurodiversity provided on the Neurodiversity Hub and the extent to which you are familiar with the terms and concepts around neurodiversity.

Aim

To investigate the level of understanding of neurodiversity in the school.

To apply key science skills including planning and conducting investigations, generating, collating and recording data.

Task preparation

To investigate the extent to which your school community (or another population of choice) is aware of the concept of neurodiversity and the depth of their understanding of various neurodiverse categories, as a class, create a list of key understandings you believe are most important for the general population to have in order to achieve inclusion and empowerment for neurodiverse individuals.

Survey creation

From this information create a Likert scale survey of approximately 20 questions to collect data on attitudes and knowledge around neurodiversity. Questions and statements may be categorised by type of neurodiverse classification, and focus on common misconceptions, stereotypes, abilities and strengths of neurodiverse individuals. Students may create hypotheses around which types of neurodiversity are more commonly understood and may wish to include questions about participants’ demographic details (such as age) to investigate whether there is a correlation between age and familiarity with neurodiversity. Teachers should approve students’ final set of questions to ensure they are appropriately phrased and refer to neurodiversity in a positive manner. It is also important that students create a consent form for participants to demonstrate their understanding of, and adherence to, ethical guidelines and participant rights, including informed consent, voluntary participation, withdrawal and debriefing.

Collection of data

Each student should collect a signed consent form from each participant before administering the survey and aim to collect data from at least 5 participants over the age of 18. Results from participants should be recorded to ensure anonymity.

Analysis of data

Collate the class data and prepare the results in a graphical format relevant to student hypotheses. Present the findings in a short report, highlighting the most common areas of knowledge and misunderstanding in the population(s).

Area of Study 2: How are mental processes and behaviour influenced by the brain?

Outcome 2

On completion of this unit the student should be able to analyse the role of the brain in mental processes and behaviour and evaluate how brain plasticity and brain injury can change biopsychosocial functioning.

To achieve this outcome the student will draw on key knowledge outlined in Area of Study 2 and relevant key science skills on pages 12 and 13 of the study design.

Detailed example 1

Investigate the transfer of skills

Background

Brain training activities are based on evidence that practice improves performance. However, practice for one cognitive skill, such as concentration, is not necessarily transferable to a different skill, such as problem solving. The evidence suggests that brain training may improve performance on ‘near’ tasks but not ‘far’ tasks (see references below).

Relevant articles in this area include:

Lindenberger U, Wenger E, Lövdén M (2017) ‘Towards a stronger science of human plasticity’. Nat. Rev. Neurosci. 18 261–262

Simons DJ, Boot WR, Charness N, Gathercole SE, Chabris CF, Hambrick DZ et al. (2016) ‘Do “Brain-Training” programs work?’ Psychol. Sci. Public Interest 17 103–186

This activity is intended to be conducted over a number of lessons, as it requires students to engage in training in a cognitive task over time before gathering their primary data on the relative effectiveness of this for improving performance on another task. It should reinforce students’ understanding of the concept of neuroplasticity and introduce them to key concepts in research before they investigate current research in Unit 1 Area of Study 3.

Aim

To investigate the impact of types of cognitive practice on cognitive task performance.

Task

Begin with the research question: Does the type of cognitive practice influence performance on cognitive tasks? and create an appropriate hypothesis. For example, Year 11 students who engage in language-based brain training will perform better on a language-based test than students who engage in non-language-based brain training.

Planning phase

  • Operationalise the IV with three appropriate cognitive tasks to represent different cognitive abilities (such as concentration, problem solving and memory) to become the IV conditions. For example, an active control group playing video games, a non-language-based condition such as playing memory with paired cards, solitaire with playing cards or small Sudoku, and a language-based condition such as playing Wordle (note that students can play more games on paper in pairs, with one student guessing and the other circling letters in the correct colour).
  • Operationalise the DV by deciding on the type of task all students will undertake at the end of the practice phase; for example, a language-based task measured with number of correct responses for a Guardian quick crossword  or a non-language-based task measured with time taken to complete a small jigsaw puzzle.
  • Specify a method; for example, completing the allocated cognitive task for the first 5–10 minutes of each Psychology lesson over 3 weeks.
  • Discuss ethical guidelines and provide students with a consent form for their parents to sign to demonstrate appropriate ethical procedures.
  • Randomly allocate students to the control and experimental conditions.

Investigation phase – testing ideas

For the training phase, allow students time to participate in the cognitive tasks over a period of time. For the testing, provide all students with the same task.

Processing phase – using evidence

Collate the data and present the results in an appropriate graphical format. Form a conclusion based on the results.

When analysing their data and forming a conclusion, students should consider:

  • the quality of evidence, including uncertainty, validity and authority of data and sources of possible errors or bias
  • characteristics of repeatable and reproducible psychological research and the consideration of uncertainty
  • criteria used to evaluate the validity of psychological research.

Detailed example 2

Model the human brain using physical models, analogies and comparative anatomy

Aim

  • Construct a model of the human brain using clay or a similar material (Part A).
  • Evaluate analogies for the structure of the brain (Part B).
  • Compare the structure of a human brain with that of a sheep or mouse (Part C).

Part A: Modelling the human brain

Materials: textbook diagrams, internet models or other pictures of the brain, clay (or plasticine, playdough, papier maché), black pen, paint colours, sharp instrument, piece of paper.

Method:

  • Refer to pictures of the brain to shape the clay into a model of the brain.
  • When modelling the brain, use the sharp instrument to model major fissures, gyri and sulci.
  • When the clay brain is dry, use different colours to map out the hindbrain, midbrain and forebrain. Also identify the four lobes of the cerebral cortex and the primary cortex for each of these lobes.
  • Use a fine black pen to number the locations of chosen brain structures.
  • Create a key for the brain model.

Discuss and then summarise findings in logbooks. Include digital photographs of the brain models.

  • Note the similarities and differences between different parts of the brain.
  • Identify the strengths and limitations of the brain model.
  • Consider one aspect of brain structure that could not be represented by the model and suggest a way that this feature could be modelled or represented.

Conclusion: As a class, discuss and reflect on the ability of scientific models (such as these models of the brain) to organise and understand observed phenomena.

Note: This activity could also be adapted to create a model of a neuron.

Part B: Analogies for brain structure

Analogies are often used in science to describe phenomena and concepts. This activity explores one analogy for brain structure.

Tasks:

  1. Undertake research to describe how the following are analogous to parts of the brain:
    • a cabbage
    • a raisin
    • a pillowcase
    • string cheese
    • a walnut
    • a grapefruit
    • an avocado.
  2. Evaluate the strengths and limitations of the use of analogies in describing brain structure.
  3. Suggest how analogies may be used to describe brain function.

Part C: Comparison of human, mouse and sheep brains

In groups, provide students with images of a human brain and another mammalian brain typically used in psychological research (for example, sheep or mouse). Alternatively, ask each group to find their own images of the brain for each animal.

Using these images and a data sheet, students record the differences in the structure of the hindbrain, midbrain and forebrain of each brain. They might also consult other sources of information to complete this structural comparison, for example the size or weight of each structure.

In groups, discuss the ability of scientific models (developed using animals brains) to organise and understand observed phenomena and concepts related to human psychological functioning. Consider the questions:

  • Why might using models and photographs of such animals’ brains be useful?
  • What might researchers need to consider when using animal models to research particular neurological disorders?

Extension activity: Students work in groups to choose a particular human neurological condition (for example, Parkinson’s disease) and research how animal models have been used to develop human models for the disorder.

Area of Study 3: How does contemporary psychology conduct and validate psychological research?

Outcome 3

On completion of this unit the student should be able to identify, analyse and evaluate the evidence available to answer a research question relating to contemporary psychology.

To achieve this outcome the student will draw on key knowledge outlined in Area of Study 3 and the related key science skills on pages 12 and 13 of the study design.

  • Consider cyborg insects as a new frontier in the relationship between nature and technology (see Singapore's Remote-Controlled Cyborg Insects). Discuss the potential positive applications of this technology, as well as the potential for harm. Relate ethical concepts to the research.
  • Crumple a sheet of paper in your hand to form a ‘clot’ approximating a sphere and measure its diameter; collate class data to plot a histogram of clot diameters and account for the shape of the histogram; identify and distinguish between sources of error and uncertainty; use the results to discuss the difference between reproducibility and repeatability; calculate the mean; discuss qualitatively how the mean and standard deviation would be similar / different if the activity were undertaken by a different class; explain why accurate measurements are important in psychology.
  • Use the CRABS framework to evaluate the validity of psychological information posted on social media.

An inquiry approach to investigate how science is used to explore and validate psychological research

See suggested approaches for developing the Unit 1 Outcome 3 Student-designed Research Investigation under ‘Assessment Advice’.

Unit 2: How do internal and external factors influence behaviour and mental processes?

Area of Study 1: How are people influenced to behave in particular ways?

Outcome 1

On completion of this unit the student should be able to analyse how social cognition influences individuals to behave in specific ways and evaluate factors that influence individual and group behaviour.

To achieve this outcome the student will draw on key knowledge outlined in Area of Study 1 and relevant key science skills on pages 12 and 13 of the study design.

Project-based learning to explore an issue relating to prejudice, discrimination, bullying and the negative influences of media

Aim

To use a Project Based Learning (PBL) approach to investigate research questions relating to prejudice, discrimination, bullying and the negative influence of media.

Introduction

Students work in small groups to undertake an in-depth inquiry into one question relating to prejudice, discrimination, bullying and negative influences of media, and create, compose or produce a product for an authentic audience.

Teaching notes

This detailed example draws on the principles of PBL developed by the Buck Institute for Education.

A PBL approach begins with an open-ended question, which is ideally provocative and engaging so that it captures students’ interest. Students investigate this question and brainstorm possible solutions, learning relevant content during the process. They then apply their learning in creative ways to produce, demonstrate or perform something, advocate for a policy or solution, or teach something to others, practising their communication skills in the process.

Each student-centred project is broken down into three main stages, which can overlap in time frame:

  • Inquire / discover / research
  • Create / compose / produce
  • Present / share / promote

Overall four questions relating to prejudice, discrimination, bullying and negative influences of the media are required for investigation. Teachers may provide these questions or develop these questions in conjunction with their students.

A manageable way to tackle this task may be:

  • determine the four questions to be investigated as a class
  • student groups to share their groups’ learning with their class peers
  • students to complete a ‘compare and contrast matrix’ for the four selected issues that addresses the following categories: factors that influence the behaviour involved, individual and community stakeholders involved, effect on individual and group behaviour, possible products and / or solutions.

Assessment can include self- and peer-assessment questionnaires and a compare and contrast matrix. In this way the contribution of each student within any group is accounted for.

Approximate time frames are proposed for each stage.

Science skills

Teachers should identify and inform students of the relevant key science skills embedded in the task.

Preparation

  • Students may need assistance in deconstructing the investigation question.
  • Students should be able to develop and administer surveys. This may have previously been covered in class, or teachers may use this problem-based learning activity to develop these skills. Teachers should check survey items to ensure their appropriateness prior to the survey being publicly distributed. Teachers should work with students to:
    1. identify the style of items in their survey that will best answer the research question (for example, Likert-type scales, dichotomous or ordinal questions)
    2. develop items to be included in the survey that will best answer the research question
    3. develop standardised procedures under which the survey will be administered 
    4. take into account relevant ethical principles including informed consent, voluntary participation, withdrawal rights, confidentiality and debriefing
    5. determine the number of survey respondents required (for example, five respondents per student).
  • Teachers could also discuss the necessary skills required to work well in a group, including perseverance and a positive attitude.

Health and safety notes

There are no specific health and safety concerns associated with this activity.

Procedure

Stage 1: inquire / discover / research

Lesson 1 plus some out-of-class time. Students:

  • Choose an investigation question (IQ) that interests them personally – ideally they make their personal interest in it explicit by recording initial ideas in the logbook.
  • Form teams of three to four people with some interest in the same IQ. The teacher may facilitate this.
  • As a team, brainstorm what they do know and do not know about the problem / investigation question. What specific questions do they need to investigate further? Each student should keep evidence of the process in their logbooks.
  • Consider how the IQ affects different people and places – research, identify and describe relevant individuals, stakeholders and community groups. What specific questions do they need to investigate further? Students need to keep evidence of the process in the logbooks and also keep a record of where they sourced the information in case they need to return to it later.

Lesson 2 plus some out-of-class time. Students:

  • Review the selected IQ and reframe / rewrite it if necessary to include specific parameters (such as particular places, stakeholders, countries etc.).
  • Nominate valid sources, such as agencies, organisations or professionals in the field, who might be able to supply information to help them answer the specific questions they identified that require further investigation.
  • Collect as much information as possible on the IQ by dividing up these tasks to individuals within their group. Remember to agree on a timeline for completion. This might include using methods such as: online/library research; surveys; interviews; photo and video documentation; experimental data; and meeting with a variety of experts with different viewpoints. As students research, it is critical they collect sufficient information that allows them to explain arguments for and against different stakeholders’ points of view. Each student should keep and share a careful log of their research – dates, times, sources, observations, summaries etc.

Lesson 3. Students:

  • As a group analyse the evidence collated during their field studies and create charts, graphs and other visual representations to understand their findings.

Stage 2: create / compose / produce

Lesson 4 plus some out-of-class time. Students:

  • Based on their research, ask what specific product / solution they would like to create that addresses the IQ. Their task is to make public a strong, convincing argument to a real / authentic audience. Does the group want to design a website, plan a community event, improve an existing project / program, initiate an action-oriented campaign, make a persuasive presentation to relevant stakeholders? Or something else?
  • Identify all the steps required to make this stage happen.
  • Make contact with their real / authentic audience and present to them a very brief description of the intended product / solution and the rationales for the inquiry into the IQ. Students keep evidence of their contact in the logbooks.

Lesson 5 plus some out of class time. Students:

  • Create the product / solution and collect evidence of the process.

Stage 3: present / share / promote

Lesson 6 plus some out of class time. Students:

  • Present the product / solution to class peers for initial review. The randomly selected class peers will complete an assessment questionnaire (based on criteria in a provided assessment rubric). Complete self- and team peer-assessment questionnaires.
  • Deliver the product / solution to the real / authentic audience. Collect evidence of the process. Randomly selected audience members complete assessment questionnaires.

Lesson 7

Students complete a written ‘compare and contrast matrix’ for the selected question that addresses the following categories: factors that influence the behaviour involved, individual and community stakeholders involved, effect on individual and group behaviour, possible products and / or solutions.

The Availability Heuristic

Aim

To involve students in a short activity to increase understanding of the availability heuristic.

To improve key science skills including use of fieldwork and analysis of quantitative data to recognise patterns.

Background

The availability heuristic is a cognitive rule of thumb in which probability of events is judged based on how readily they come to mind. This misjudgment may be based on familiar ‘facts’, personal experiences or over-emphasis in media reporting.

This activity could be completed as an introductory activity before the theory of heuristics is covered. Alternatively, it could be carried out after the theory has been explored as a method to deepen understanding with a practical and personal activity.

Overview of task

Step 1: Advise students that you will be asking them three questions. For each question they are to jot down the immediate answer that comes to mind (yes, no, don’t know).

Step 2: Ask the following three questions ensuring that there is no discussion and that responses are noted quickly:

  • Has the number of Australian secondary school students drinking alcohol been increasing since 1996?
  • Has the number of Australian secondary school students carrying our risky drinking been increasing since 1996?
  • Has the number of Australian secondary school students using cannabis been increasing since 1996?

Step 3: Collate the class data to determine what percentage of students answered yes / no / don’t know to each question.

Step 4: As a class access the latest Australian Secondary Students Alcohol and Drug (ASSAD) survey

Step 5: Discuss the following points:

  • Are the class results in line with the findings of the ASSAD survey?
  • If students were more likely to believe that alcohol and cannabis use was increasing, discuss in relation to the availability heuristic.
  • For those who answered yes, what were some of the reasons that immediately came to mind? This may include media reporting, stereotypes, and a limited personal sample. Relate to the availability heuristic.
  • For those who answered no, what were some of the reasons that immediately came to mind? This may include study in another subject, media reporting or personal experience. Relate to the availability heuristic.

Step 6: Explore the ASSAD survey in relation to key science skills, including:

  • Is this study a controlled experiment? Why or why not?
  • The study uses both stratified and random sampling. What does each method involve? What are the advantages and limitations of each method? Why were both methods used in this survey?
  • The sample size for the ASSAD survey is typically around 20,000 students. How may this sample size influence external validity?
  • What are some factors that could influence the accuracy of the results? How could these be minimised or controlled?

Area of Study 2: What influences a person’s perception of the world?

Outcome 2

On completion of this unit the student should be able to explain the roles of attention and perception, compare gustatory and visual perception and analyse factors that may lead to perceptual distortions.

To achieve this outcome the student will draw on key knowledge outlined in Area of Study 2 and relevant key science skills on pages 12 and 13 of the study design.

Examples of learning activities

  • Conduct a practical activity based on the Stroop effect.
  • Watch online videos that demonstrate inattentional blindness / change blindness. Complete a project to create your own change blindness video.
  • Comment on Sir Arthur Conan Doyle’s quote from The Memoirs of Sherlock Holmes, ‘You see but you do not observe’ in terms of visual perception, attention and distortion of perception.
  • Carry out a controlled classroom experiment to test the effect of divided versus selective attention on a listening comprehension task.

  • Play a fast-acting card game or board game (such as Snap or 4 in a Row) and relate to the different forms of attention.
  • Investigate the role of video games in improving selective and sustained attention.
  • Discuss Cristina Marrero’s quote: ‘The Scientific Method is a wonderful tool as long as you don’t care which way the outcome turns; however, this process fails the second one’s perception interferes with the interpretation of data. This is why I don’t take anything in life as an absolute…even if someone can “prove” it “scientifically”.’
  • In small groups, with a 500-piece jigsaw puzzle and without the overall picture, select pieces of the jigsaw, examine and pass around one at a time. After 5 minutes each member of the group draws an image of what they believe the overall puzzle picture might be. Teacher reveals the actual puzzle image and class discuss which elements of the activity demonstrate bottom up processing and top down processing.
  • Feel various items placed in a box and guess what they are just by feel. Create a flow chart explaining the guessing in terms of top down and bottom up processing. Alternatively carry out this activity using a blindfolded taste test.
  • Analyse the B/13, ratman and other ambiguous visual images in terms of the role of top down and bottom up processing.
  • Consider a media article such as My Life With Face Blindness in light of the role of top down and bottom up processing.
  • In terms of top-down and bottom-up processing, consider the internet meme that letters in a word can be jumbled, but as long as the first and last letters remain the same, the meaning can be interpreted. Additionally, consider the accuracy of this common internet meme in light of an article on the University of Cambridge’s MRC Cognition and Brain Sciences Unit web page.
  • Undertake an eye dissection, examining the main structures and components of the eye.
  • Participate in activities that illustrate phenomena in the visual perception system; for example locating the blind spot, producing a negative after-image.
  • Undertake the Ishihara test for colour blindness and explain how such tests relate to the sensation and perception of visual stimuli.
  • Use a ray box to demonstrate the concept of accommodation.
  • Use a pen to demonstrate the concept of convergence: focus on the tip of the pen and move the pen closer to the nose; notice the change in muscular tension in the eye as the pen moves closer to the nose. An observer can record what happens to the eyes as the experimenter tries to keep the pen tip in focus as the pen moves toward their eye.
  • Consider how monocular depth cues are used to create the perception of depth and the appearance of three dimensions in a chosen artwork.
  • Participate in activities that involve using 3D glasses.
  • Take photographs of symbols from the everyday world (for example: at work, on the way home from school, during weekend activities). In groups, present the symbols and describe how Gestalt principles are used to create meaningful perceptions of the images.
  • Use a tri-Venn diagram to show the biological, psychological and social influences on gustatory perception and / or visual perception.
  • Design and conduct a survey to explore one of the following questions:
    • How common is the taste aversion to coriander?
    • Is preference for spicy foods linked to early life experiences?
    • Does preference for sweet versus savory foods change with age?
    • Do people who exercise a lot also eat healthier food?
  • Visit a shopping centre food court and observe and record which food outlets are the most popular. Hypothesise reasons for this based on both psychological and social factors.

  • Analyse the Gestalt principles used in artworks by visiting a local art gallery, visiting the online collection of the National Gallery of Victoria or looking at children's picture books.
  • Identify foods from other cultures that you personally find challenging to eat. Then identify foods that you eat that people from other cultures may find challenging to eat. Suggest reasons for this based on social factors.
  • Water security is increasingly becoming a serious issue in Australia due to the combined impacts of population growth and climate change. One necessary and safe solution is to treat sewage water for drinking water. Explain why one of the biggest hurdles for this is ‘between our ears’.

Reflective blog – what influences a person’s sensations and perception of taste?

Aim

This task is staged over a few weeks of class time and involves students undertaking a series of practical activities as part of the regular teaching and learning program for Unit 2 Area of Study 1.

Students create an online blog that includes a selection of relevant practical activities that enables them to compare the sensations and perceptions of taste and analyse the factors that may lead to the occurrence of perceptual distortions of taste.

Procedure

For each practical activity, students may be asked to formulate hypotheses or make predictions in relation to sensation and perception. They undertake investigations relating to human taste that involve the collection and recording of data, analysis of data and the methods used to draw evidence-based conclusions based on their investigations, and identification of associated scientific theories and models.

In this example, the chosen format for communication of their scientific ideas is an online reflective blog (using a selected blogging website of choice such as Global2.vic.edu.au). The practical activities may involve the student conducting an experiment, being a participant in an experiment or acting as an observer in an experiment. The student may be involved in these activities individually, or as one student in a small group, or as a member of the whole class. The key knowledge to be addressed includes the processes involved in sensation and perception: taste as an example of human sensory systems; biological, psychological and social factors that influence gustatory perception; and the fallibility of gustatory perception systems.

At the time of undertaking each practical activity, the student should record the details of the activity in their journal / on their blog. Students could be encouraged to take digital photographs to record the data as evidence of their participation in the practical activities and upload these under the relevant blog entries.

Suggestions for practical activities that could be undertaken by students as part of this reflective learning journal / blog include:

  • influence of colour intensity of different drinks on their perceived sweetness
  • influence of being blind folded on correct flavour identification of different flavoured drinks
  • judgment of perceived crispiness of food based on noisiness of packaging
  • influence of temperature on perceived sweetness
  • influence of brand labels and no labels on perceived taste preference
  • changes in salt sensitivity with age
  • influence of stress on ability to distinguish different flavours / tastes
  • influence of the Delboeuf illusion on satiety
  • influence of temperature on perceived bitterness
  • influence of price on perceived taste preference
  • effect of nose-holding on the perception of taste.

The student reflects upon the practical activities undertaken in terms of the overall research question. The teacher may decide whether to provide a set of guiding questions to assist student reflections or whether to allow students to make their own reflections based on a general question or related to a specific aspect of the area of study. The teacher should also determine when the reflections are to be completed, for example immediately after each practical activity, or after a series of practical activities, or in a block at the end of the area of study.

Exploring factors influencing gustatory perception towards eating insects

Aims

To explore the factors influencing gustatory perception of eating edible insects.

To develop secondary data skills through analysis of a contemporary Australian study.

To develop primary data generation and analysis skills.

Background

Eating insects as a protein source is likely to increase in the future. These activities explore the social factors that may influence Australians’ willingness to try and incorporate insects as a food source.

Step 1: Tuning in

Brainstorm and discuss the reasons that eating insects as a protein source is likely to increase in the future. Identify and discuss students' reactions to the thought of eating insects. Classify these reactions as social or psychological.

Step 2: Accessing a secondary source of information

Access a secondary source of information on Australia’s willingness towards consuming edible insects. For example, the journal article by Hopkins et al (2021) Australians’ experience, barriers and willingness towards consuming edible insects as an emerging protein source. Note: this is an open source journal article so all sections are freely available. Note: while the article is quite long it is written in a fairly accessible manner.

Depending on the cohort, students may read the whole article or break the article into sections with different students / groups focusing on a section each. Alternatively, you may provide a summary of the article or use a media article summarising the research such as this one on the The Conversation.

Step 3: Interpreting and analysing the scientific investigation

Depending on the cohort, decide on the best way to analyse the secondary source of information. Some suggestions follow:

Using a graphic organiser such as a flow chart, summarise the research methodology and findings under the following headings: aim of research, study type, methodology, results, discussion, conclusion. This could be done by individual students, small groups or as a whole class.

Carry out a scavenger style challenge for individuals or small groups of students to locate information and answer questions regarding the study aim, methodology, results and findings.

Step 4: Classifying the gustatory factors

Using a graphic organiser such as a mind map or table, summarise the biological, social and psychological factors identified in the article that may influence willingness to try insects.

Note: this may present a good opportunity to connect and review topics covered in Area of Study 1 including attitudes, cognitive dissonance, use of heuristics for decision-making, conformity, and the influence of different media sources.

Step 5: Carrying out primary research to replicate the investigation

In small groups or as a class, design a method to replicate / modify / extend the research by surveying the local school community. This is a good opportunity to discuss the difference between primary and secondary research, qualitative and quantitative data, as well as the concept of reproducibility.

You may choose to use / modify the original survey questions used by Hopkins et al (2021). These are available online as a link at the end of the report in Appendix A: supplementary data. It is suggested that you remove some or all of the screening questions to ensure that sensitive information is not gathered. 

Consider whether the research will be carried out using an online platform or in a paper-based format.

The class will then collate the results and process the data obtained using appropriate mathematical calculations and units (such as the mean and percentage). Then it will be organised and presented in an appropriate format such as a table.

The class findings can then be compared to the Hopkins et al (2021) research and any similarities / differences identified and discussed. This may present an opportunity to discuss errors, extraneous and confounding variables, uncertainty, reproducibility and external validity.

Area of Study 3: How do scientific investigations develop understanding of influences on perception and behaviour?

Outcome 3

On completion of this unit the student should be able to adapt or design and then conduct a scientific investigation related to internal and external influences on perception and / or behaviour and draw an evidence-based conclusion from generated primary data.

To achieve this outcome the student will draw on key knowledge outlined in Area of Study 3 and the related key science skills on pages 12 and 13 of the study design.

Examples of learning activities

  • Discuss the quote ‘There are in fact two things, science and opinion; the former begets knowledge, the latter ignorance’ (Hippocrates).
  • Watch a short cartoon clip (such as Tom and Jerry) and individually observe and record the number of aggressive behaviours.

    • How does ‘multi-tasking’ influence accuracy on a hand-eye coordination task?
  • Annotate target board images to visually represent the concepts of accuracy and precision.
  • Test heart rate via a number of different means (for example: fingers on wrist, fingers on neck, heart rate monitors). Compare the results as a basis for discussing the concepts of accuracy, precision, random errors, systematic errors, personal errors and reproducibility.
  • Use a Venn diagram to distinguish between the concepts of accuracy and precision.
  • Use a Venn diagram to distinguish between the concepts of reproducibility and repeatability.
  • Make a checklist of things to consider when assessing the credibility and validity of a piece of psychological research.
  • As a class, create a set of guidelines to ensure that health, safety and ethical guidelines are met when carrying out practical research activities.
  • Using a concept such as gustatory perception, distinguish between a theory, model, aim and hypothesis.
  • Provided with a range of research scenarios and statements, classify them as either primary or secondary data.
  • As a class, create a one-page reference document with key advice on methods to organise and analyse primary data (for example: when to use different graph types, how to work out mean, headings and labels, how to spot outliers).
  • As a class, discuss the purpose of logbooks in psychology research.
  • Make a checklist of features that should be part of a scientific logbook (such as being dated and chronological).
  • Scientific posters are typically used at large conferences. With this in mind, discuss why poster conventions, word brevity and clear data analysis in graphs / tables is important.
  • Conduct a web search for ‘scientific poster’ images. Identify similarities in headings, layout and content. Identify differences in the posters and consider the features that enhance effective communication.
  • When looking at studies from a textbook or other sources, write a ‘communication statement’ reporting the key finding of the investigation as a one-sentence summary.
  • Discuss the real life implications of theories and models by answering questions such as: For whom are these findings most relevant? How can these findings be used to advance society? Is there the potential for these findings to be applied in an unjust manner?

Area of Study 1: How does the nervous system enable psychological functioning?

Outcome 1

On completion of this unit the student should be able to analyse how the functioning of the human nervous system enables a person to interact with the external world, and evaluate the different ways in which stress can affect psychobiological functioning.

To achieve this outcome the student will draw on key knowledge outlined in Area of Study 1 and relevant key science skills on pages 12 and 13 of the study design.

Examples of learning activities

  • Using chalk and concrete (outdoors) or butcher’s paper and textas (indoors), and working in pairs, trace a life-sized outline of each other’s body. Each student then uses their own outline to fill in each division of the human nervous system, using a different colour for each division; labels should be added to indicate the function of each of the divisions.
  • Construct a flow chart explaining how the different divisions of the nervous system respond to, integrate and coordinate, when a person does a particular action; for example, picks up a hot cup of coffee, pats a dog, catches a ball.

  • Complete a Venn diagram outlining the similarities and differences between conscious and unconscious responses.
  • Conduct controlled experiments into reflex actions; for example, the reaction time of a human nerve-controlled reaction. See Backyard Brains for a lesson plan.
  • Create a folio of a range of related experiments and activities exploring the nervous system as outlined in 'Neuroscience for Kids’.
  • Work in pairs to formulate a hypothesis and investigate experimentally the factors that affect reaction times in catching a dropped ruler; for example, gender, age, level of alertness, before or after eating. Draw the neural pathway to illustrate how messages travel from the stimulus to the action.
  • Produce a cartoon or other visual sequence format to illustrate the role of the spinal reflex.
  • Play a ‘walk the plank’ game using a VR headset (this could be a purchased headset or a simple cardboard headset from an online template). Compare heart rate before, during and after the activity as a basis to discuss sympathetic nervous system activation and the role of simulation as a study methodology.
  • Explore the use of exoskeletons controlled by a brain-machine interface, such as in the video: Exoskeleton Controlled by a Brain-Machine Interface. Use the clip as a stimulus to discuss the crucial role of the spinal cord, the complexity of processing and coordinating with sensory stimuli, and the potential promises and perils of new technologies.

Detailed example 1

Conduct a simulation activity demonstrating the speed of neural transmission

Background

The speed of neural transmission is estimated to be 70–120 meters per second (m / s). Therefore the time it takes for sensory and motor messages to travel through the body increases the further they have to go. This task helps students appreciate exactly how fast this process is, while also reinforcing their understanding of research method terms. Note: typically this simulation activity will yield a number of errors as students familiarise themselves with the process. This is actually preferable since errors will contribute to a good discussion and assist students in understanding the subject matter.

Aim

To simulate the speed of neural transmission.

Hypothesis

That neural transmission will be faster when it has less distance to travel.

IV: squeezing the shoulder or ankle

DV: time taken for pulse to pass around a circle

Method

Students will sit in a circle to pass a ‘pulse’ around the group. Ask students to rest their hand on the shoulder of the person to their right and close their eyes. One student will start and each student is to pass on the squeeze as soon as they feel it. The first student should start the timer as they squeeze the first person. Repeat this process five times to get an average ‘shoulder’ recording. Then ask another student to start the squeeze and be the timekeeper.

Repeat the process but this time with students holding the ankle of the person next to them.

Results

Present the data in an appropriate graphical format and compare the average times.

Discussion

Explain why the first condition is faster and evaluate any methodological issues, including data and measurement, and errors, uncertainty and outliers.

Questions that may be asked are:

  • How accurate is the measurement of neural transmission collected?
  • Were there any systematic errors?
  • How precise were the measurements of neural transmission?
  • Were there any random errors? Were there any personal errors?
  • Were there any outliers?
  • Was repeatability of measurement demonstrated?
  • Were the results reproduced by the second timekeeper in each condition?
  • Would it be possible to measure the true value of speed of neural transmission this way?
  • Is this a valid measurement of the speed of neural transmission?

Stress in Japan

Aims

  • To investigate the Japanese tsunami of 2011 and its ongoing effects as a major source of stress for the Japanese population.
  • To examine the nature of scientific evidence.

Background information for teachers

Japan, being geologically located at the nexus of four tectonic plates, experiences more than 1,500 seismic events each year, including at least two 5.0 magnitude or higher earthquakes. As a result, between 1608 and 1945 Tokyo was destroyed and rebuilt, on average, once every five years. On 11 March 2011, a magnitude-9 earthquake shook northeastern Japan, also creating a devastating tsunami. The effects of this earthquake were felt globally and tsunami debris continues to wash up as far away as in North America. Residents are still recovering from the disaster.

Students are provided with the following data collected by an American reporter. Some data comes from secondary sources, such as previous studies and government-based statistics and some has been collected through interviews with Japanese residents (primary data):

  • The disaster has caused an increase in suicides, PTSD, and stress-related physical ailments like cardiovascular disease. In particular, the number of stress-related deaths (1,656) reported by the Japanese government, has topped deaths directly caused by the earthquake, tsunami, and nuclear meltdown combined.
  • In 2010, NYU sociologist Florencia Torche studied the impact of the 2008 Chilean earthquake on mothers with infants then in utero. She found the heightened levels of cortisol in mothers of infants born in the first trimester of the quake led to lower birth weights, earlier birth rates, and increased cortisol levels in their children. Those born in earthquake areas are, after 14 years, at a cognitive and physical disadvantage: They performed worse in school and didn’t boast as strong a stature. Torche’s findings show that the effect of an earthquake ‘can exist over the individual’s entire life—even across generations’.
  • There is some evidence that the Japanese are being similarly affected. Japanese people of all ages are more likely to carry a gene that predisposes them to react more strongly to stressful events than people outside of Japan. In a 2008 study, Japanese infants were found to react to the pain of being inoculated with more cortisol than American infants did, though they also whined less than the Americans.
  • Stress could also explain Japan’s famously low birth rates: exposure to stressful environments is correlated with lower sperm counts, ovulation issues, and other issues of reproductive functioning. High levels of chronic stress and cortisol decrease sex drives in women, and in Japan, a full 45 per cent of women reported they were ‘not interested in sexual contact’—and more than 25 per cent of Japanese men feel the same way.
  •  ‘The Japanese talk about stress a whole lot less than Americans talk about stress,’ says Bill Tsutsui, a Japanese-American historian. ‘And yet, to me, Japanese society is the most stressful on the planet.’ Even though only 2.5 per cent of Japanese people are diagnosed with depression at any given time, compared with 6.7 per cent of Americans, the suicide rate among Japanese people is 20.1 per 100,000, compared to 12.6 for Americans.
  • The stigma surrounding mental health means that for many, the idea of reporting stress is more stressful than simply living—or dying—with it. ‘The stress of social interaction has caused a flight from human intimacy. You cannot open your mouth to say a word without considering your relationship with the people around you—your place in the hierarchy. And if you say something wrong you risk grievously offending people.’

Science skills

Teachers should identify and inform students of the relevant key science skills embedded in the task.

Activity 1: Stress as a psychobiological process

  • Students can work in small groups to read and complete a simple summary of the psychobiological aspects of the evidence provided in a table:
Psychological Factors / ExamplesBiological Factors / Examples

 

 


Discussion questions and report writing in logbook

A series of four to eight graded questions could be set for students to answer in their logbook, for example:

Connect: Identify any direct links between biological and psychological examples of stress provided in the evidence.

Explain: Why would the 2011 Tsunami be considered a major stressor? Why would it also be considered a catastrophe? Why would it be categorised as distress?

Apply:

  1. Using your understanding of Selye’s General Adaptation Syndrome, explain how the Japanese people would have progressed through the relevant stages. Be sure to use any relevant evidence and reference the role of cortisol.
  2. Using your understanding of Lazarus and Folkman’s Transactional Model of Stress and Coping, explain the psychological process of stress that the Japanese people would have gone through.

Propose: Using your understanding of context-specific effectiveness and coping flexibility, suggest some ongoing strategies that would help the Japanese people reduce the symptoms of their ongoing stress.

Activity 2: Evaluation of data

Students could be asked to write an extended response in which they are required to critically evaluate the evidence provided in Activity 1 by considering all or some of the following dot points:

  • The type(s) of data obtained (qualitative versus quantitative)
  • The reliability and validity of the data obtained
  • Investigative procedures (interview) used to obtain the data
  • Possible sources of bias within the data
  • Any distinctions that can be made between scientific and non-scientific ideas.

Area of Study 2: How do people learn and remember?

Outcome 2

On completion of this unit the student should be able to apply different approaches to explain learning to familiar and novel contexts and discuss memory as a psychobiological process.

To achieve this outcome the student will draw on key knowledge outlined in Area of Study 2 and relevant key science skills on pages 12 and 13 of the study design.

Investigation of sleep patterns across the lifespan

Aim

To compare patterns in the total amount of sleep in a 24-hour cycle across various age groups.

Introduction

Students investigate the relationship between age and the total hours slept by individuals of varying ages. The task requires students to access a small number of participants of different ages (for example: an infant, a child, an adolescent, an adult and an elderly person). Students are required to collect data, use evidence and transfer their findings to explain this relationship.

Science skills

Teachers should identify and inform students of the relevant key science skills embedded in the task.

Pre-activity preparation

The task follows class work on the importance of sleep, circadian and ultradian rhythms, patterns of sleep and theories of its purpose. A review of self-reports and the use of quantitative data may also be required.

Procedure

  • Each class member surveys at least one participant in each of the age groups.
  • Students should approach each potential participant and say ‘I am a VCE student doing a survey on sleep patterns as a learning activity; would you mind if I ask you a few short questions? This survey is entirely anonymous’. Note: if the participant is an infant or a child, the students will need to ask the participant’s parent this question.
  • If the participant indicates a willingness to take part, ask ‘Could you tell me which of these age groups applies to you?  0–2, 3–12, 13–18, 21–64, 65+.’ Note: if the participant is an infant or a child, the students will need to ask the participant’s parent this question.
  • Students then record the age group of the participant and ask: ‘For each of these questions, could you think back and give the average figure for the past week?
    1. On a normal day, how many hours did you sleep?
    2. On average, how many times did you wake up during each night?
    3. If you did wake up in the night, on average for how long did you remain awake?
Age groupHours of sleep reportedNumber of times awokenTime spent awake
Infants (0–2)

 

 

 

Children (3–12)

 

 

 

Adolescents (13–18)

 

 

 

Adults (19–64)

 

 

 

Elderly (65+)

 

 

 


Results

Class members ‘pool’ their results and process the quantitative data obtained, using appropriate mathematical calculations and units (for example, descriptive statistics such as a mean). They organise, present and interpret the data using an appropriate table or graph.

Discussion questions and report writing in logbook

A series of four to six graded questions that address the data and the implications of the relationship between the total amount of sleep and patterns of sleep across the lifespan should be set for students to answer in their logbook, for example:

  • Identify: What are the dependent and independent variables in your investigation?
  • Explain: According to your data, how does the pattern of sleep change across the lifespan?
  • Evaluate: Discuss any potential extraneous variables and how they have affected the data on sleep gathered? Suggest future improvements to address these if the investigation was to be repeated.  
  • Propose: What further data could be gathered to investigate how patterns of sleep change across the lifespan? Outline a method for a further testing. 

Teaching notes

  • It is important that students understand how to collate the data and perform any calculations. Some students may not, and teachers should lead students when collating the data and demonstrate some calculations; for example, the mean values for the first age group (infants) in the table.
  • Further investigation gathering qualitative data about the quality of sleep, dysomnias and parasomnias could also be conducted.

Analysis of a contemporary media text and design of a related investigation

Aim

To analyse and evaluate a media article regarding sleep in relation to key science skills and psychological theory.

To use the article as stimulus material to design a study.

Background

This activity relates to numerous key knowledge points in Unit 4, Area of Study 2, including regulation of sleep-wake patterns by internal biological mechanisms, with reference to melatonin; and improving sleep-wake patterns with reference to eating and drinking patterns. The activity also links heavily to the key science skills. It would be best to run the activity at the completion of the area of study. The activity could be run as a structured class discussion or individual student entry into logbooks.

Read one of the following articles which claim a link between eating eggs and increased melatonin levels for a good night's sleep: 'Sleep experts say eggs are the secret to a good night's sleep' or 'This 50c staple is scientifically proven to help you sleep better'.

Questions for class discussion or individual student entry into logbooks

Connect and explain – Sleep psychological theory

  • Identify links between the claims made in the article and sleep-wake patterns and sleep hygiene.
  • Why may eggs be beneficial in improving sleep?
  • Why might eating the eggs two hours before going to bed be important?
  • Why might it be suggested to not have a large or heavy meal close to bedtime?

Evaluate – Key science skills

As presented in the article, would the information be considered opinion, anecdote or evidence?

As presented in the article, is the information scientific or non-scientific in nature?

What conclusion is made in the article and what are the limitations of this?

How does the concept of validity relate to the claims made in the article?

The article concludes with a link to a food industry website. How does this link to the ethical concepts of integrity and justice?

Create (Key science skills) – Design a study to test the claim made in the article that eating two eggs before bed increases melatonin and improves sleep

  • What would be an appropriate investigation methodology to test the claim made in the article?
  • How would you design and conduct an investigation to test the claim made in the article (consider sampling technique, procedures, measurement of variables)?
  • What sort of data would you generate (qualitative or quantitative or both)?
  • How would you minimise potential extraneous or confounding variables?
  • How would you minimise potential sources of error or uncertainty?
  • How would you ensure that the ethical guidelines of information consent, withdrawal rights and debriefing are followed?

Role of melatonin in regulating sleep-wake patterns

Aim

To apply key science skills to the analysis and evaluation of a generated set of primary data.

To deepen understanding of the role of melatonin in regulating sleep-wake patterns.

Background

This activity uses a generated set of primary data to explore key science skills and deepen understanding of the interrelated role between blue light and melatonin levels. It would be best carried out at the conclusion of the area of study.

Students are provided with a scenario and a set of data and they answer a series of discussion questions.

Example of a scenario with generated primary data

Amara is a university psychology student who conducted a study to test the influence of mobile phone use on melatonin levels. She recruited seven other university psychology students to take part in the study, ensuring that none of them were on melatonin medication or supplements. After reading the participant information sheet about the specific purposes of the study and signing a consent form, the participants were asked to record the number of hours spent on their phone after 5pm each night for one week. Participants who on average used their phones for more than 150 minutes per evening were categorised as the high user group. Those who used their phone on average for less than 150 minutes per evening were categorised as the low user group.

When designing the study Amara had a choice of two different branded melatonin test kits. To determine the most precise test she repeated each test herself three times within a ten-minute period around midnight on a single night. The results were as follows:

Table 1: Results of Amara’s testing of the two different branded melatonin test kits at midnight

The expected melatonin range based on healthy population studies are:

Time Melatonin range pg / mLMelatonin target range pg / mL
Midnight 40–15095
6–8am< 145

Once Amara had determined which brand of test kit to use, each participant was provided with one melatonin test kit and given the following instructions: Two saliva specimens are to be collected on Wednesday night. The first at midnight and the second in the morning between 6am and 8am. You must fast from 10pm the evening before taking the midnight saliva specimen. The midnight saliva specimen must be taken in a darkened room with low light, if possible, as bright light will reduce the production of melatonin.

Once the melatonin results were back from the laboratory, Amara presented the information as in the table below:

Area of Study 2: What influences mental wellbeing?

Outcome 2

On completion of this unit the student should be able to discuss the concept of mental wellbeing, apply a biopsychosocial approach to explain the development and management of specific phobia, and discuss protective factors that contribute to the maintenance of mental wellbeing.

To achieve this outcome the student will draw on key knowledge outlined in Area of Study 2 and relevant key science skills on pages 12 and 13 of the study design.

Case study analysis of the development and management of specific phobia

Introduction

At this stage, students would have completed the following areas of the course: defining mental wellbeing, application of a biopsychosocial approach to explain specific phobia. Students are presented with a case study of an individual with specific phobia (refer to the case study in the learning activities related to Vicky’s phobia of dandelions as a further example to the case of Don’s claustrophobia provided below) that they are required to analyse.

Science skills

Teachers should identify and inform students of the relevant key science skills embedded in the task.

Activity 1: Case study scenario

Students are provided with a case study of a person who has a specific phobia. For example:

‘Donald (Don) is a 59-year-old male who works in a state government office as an accountant. He enjoys his work and the people he works with. He has worked for the government in this position, or similar positions, for the last 25 years. His salary is quite good and he has excellent benefits; however, recently he has been seriously considering retirement. In fact, he and his wife Barb have been talking about going on a road trip in their campervan when he does. Don’s main reason for retiring, though, is that the whole accounting department has recently been consolidated from several different locations. This had been done to improve efficiency. For Don, the problem with this consolidation is that he has a significant fear of small, enclosed spaces such as elevators (claustrophobia). So, when his office first moved, Don tried to use the stairs to get to his office but he found this very difficult because of his arthritic left knee. The combination of his fear and his physical problem led to him beginning to dislike going to work. So much so that he would ask Barb to call in ‘sick’ for him, which she became really concerned about. Despite recognising that his fear is irrational and out of proportion to the actual dangers involved in elevator travel, Don is still unable to stop avoiding travelling on elevators. In fact, Don’s claustrophobia is something he has suffered from for a very long time. It seems his problems began when he was a young child when his older brother locked him in his bedroom closet. It was done as a prank, but Don became extremely fearful, his heart was racing and he felt out of breath. He had what he now recognises as being a panic attack. Despite pounding on the door and begging to be let out, his brother only released him an hour later. Ever since that event he remembers avoiding enclosed spaces of all types and even as a teenager he had to have a light on in his bedroom at night.’

In small groups, students are provided a blank version of a BPS table and asked to identify any contributing factors in relation to the development of the specific phobia in the case study.

The Biopsychosocial (BPS) approach

Biological factors

Psychological factors

Social factors

Activity 2: Discussion questions

Contributing Factors

  • Determine where you think the individual in the case study sits on the mental health continuum. Justify your placement, based on your understanding of the distinction between stress, phobia and anxiety.
  • Choose one relevant biological contributing factor to the individual’s phobia and discuss its potential role in the development of their phobia.
  • Explain the role of classical conditioning in precipitating the individual’s phobia.
  • Discuss the role of operant conditioning in perpetuating the individual’s phobia.
  • Identify and explain any specific environmental triggers of the individual’s phobia.

Interventions and / or Management

  • Suggest a biological intervention and explain how it might benefit the individual.
  • Explain how CBT could be used as a psychological management intervention for the individual.
  • Using the language of classical conditioning, explain the process that would be involved in using systematic desensitisation as a psychological intervention for the individual.
  • Discuss the importance of involving the individual’s family / supporters as a part of their therapy.

Teaching notes

It is important that students gain practice at applying the BPS to varying mental health case studies or scenarios. Initially, students may need guidance and could benefit from completing an initial analysis of a case study as a class or in small groups.

Area of Study 3: How is scientific inquiry used to investigate mental processes and psychological functioning?

Outcome 3

On completion of this unit the student should be able to design and conduct a scientific investigation related to mental processes and psychological functioning, and present an aim, methodology and method, results, discussion and conclusion in a scientific poster.

To achieve this outcome the student will draw on key knowledge outlined in Area of Study 3 and the related key science skills on pages 12 and 13 of the study design.

Examples of learning activities

  • Example icon for advice for teachers
    Develop skills in designing and conducting a scientific investigation related to mental process and psychological functioning, presenting findings in a scientific poster. (see Detailed example)
  • Discuss the importance of developing investigable questions for scientific investigation in light of Albert Einstein’s quote: ‘The important thing is not to stop questioning’, Robert Half’s quote: ‘Asking the right questions takes as much skill as giving the right answers’ and Nancy Willard’s quote: ‘Sometimes questions are more important than the answers’.
  • Comment, in terms of the nature of science, on Bill Gaede’s quote: ‘Science is not about making predictions or performing experiments. Science is about explaining’.
  • Design and conduct investigations to answer the following questions:
    • Does using a reward when learning a new task affect learning?
    • Does using a punishment when learning a new task affect learning?
    • Does practice improve performance?
    • How does using a mobile phone affect dance moves?
    • How distracting are distractions?
  • Devise an inquiry to investigate the effectiveness of different learning techniques (summarisation, highlighting or underlining, keyword mnemonic, elaborative interrogation, self-explanation, imagery for text, rereading, practice testing, distributed practice, interleaved practice) based on the work of Dunlosky et al (2013.
  • Design and undertake an experiment to determine whether applause improves human or other animal performance; identify how the ethical issues associated with the experiment can be resolved.
  • Design and conduct an experiment to determine whether experiences or incidents need to have a strong emotional component to be placed and stored as part of long-term memory.
  • Apply coupled inquiry to develop and investigate questions related to memory for example:
    • Does using labels assist in the retention and recall of information?
    • What factors affect encoding and retrieval of information when playing the ‘Rumour Game’?
    • How important are cues in memory?
  • Design and conduct controlled experiments to determine whether:
    • highlighting words or writing them down increases their recollection
    • recall of information is affected by the time of day at which information is learnt
    • different types of background music affect memorisation skills of students
    • eating breakfast improves memory
    • eating particular foods improves memory
    • people can more easily remember a series of numbers, words, patterns or colours
    • using a different type of font for a set of words improves their recall
    • using different coloured paper on which words are written improves their recall.
  • Formulate hypotheses; then plan and undertake investigations to determine whether particular scents (lavender, rose, chocolate, peppermint, vanilla, white musk, lavender and citrus) increase capacity to remember a list of words. Extend the investigations to determine whether there is a gender or age difference in the capacity to remember words when subjected to different scents. Suggest a physiological mechanism or neural pathway whereby particular scents could increase a person’s capacity to improve their memory.
  • Design and conduct an investigation to determine which method of information delivery (audio, visual, mnemonic, repetition, note-taking, cramming, use of flashcards, reading words aloud) is more effectively remembered, both in the short-term and after a longer period.
  • Formulate a hypothesis and undertake an investigation to determine whether text colour affects how well information is recalled.
  • Devise and undertake an investigation to determine whether certain types of animal pets (dogs, cats, mice, fish, birds) provide greater physical (for example, blood pressure) and mental health (for example, performance on the Penn State Worry Questionnaire) benefits to their owners. Explain how variables were controlled and identify extraneous and confounding variables that may affect investigation conclusions.
  • Design an investigation to determine whether the ‘earworm effect’ (songs that get stuck in your head) is real. Modify an experimental design to investigate the aspects of songs that may cause the ‘earworm effect’.
  • Access the research reported at dailymail.co.uk, news.com.au or sciencedaily.com to develop and test an investigable question related to the relationships between sleep and memory, or sleep and wellbeing.
  • Design and conduct an investigation to determine whether binaural music is effective as a stress management technique (or as a means to induce faster sleep onset).
  • Visit the website Spurious Correlations to discuss the key concept that correlation does not equal causation.
  • Use a Venn diagram to distinguish between extraneous and confounding variables.
  • A variable is considered to be confounding when it provides an alternative explanation to results; that is, an alternative explanation for the relationship between the IV and DV. This threatens the internal validity of a study. Apply this information to research examples, such as the following:
    • In a study looking at the effectiveness of mnemonic techniques on long-term memory one group learns about acronyms and acrostics through an interactive online session. Another group learns about the method of loci through a face-to-face small group discussion. Both groups are then provided with a list of terms to memorise using their technique. Over the next few weeks their long-term memory is tested at several points.
  • For the following scenarios brainstorm possible techniques for primary quantitative data generation; then discuss the challenge that exists in measuring subjective experiences:
    • stress levels
    • sleep quality
    • cognitive development
    • attitude towards electric vehicles
    • mental wellbeing.
  • Annotate target board images to visually represent the concepts of accuracy and precision.
  • Test heart rate via a number of different means (for example, fingers on wrist, fingers on neck, heart rate monitors). Compare the results as a basis for discussing the concepts of accuracy, precision, random errors, systematic errors, personal errors and reproducibility.
  • Use a Venn diagram to distinguish between the concepts of accuracy and precision.
  • Use a Venn diagram to distinguish between the concepts of reproducibility and repeatability.
  • As a class, create a set of guidelines to ensure that health, safety and ethical guidelines are met when carrying out practical research activities.
  • Formulate a hypothesis and design an experiment to test whether people can pay attention to two things at the same time.
  • Design and conduct an experiment to test the claim that watching goldfish has a calming effect on people.
  • Devise an inquiry to test the statement that singing is an effective form of stress release.
  • Develop a hypothesis and undertake an investigation to determine whether there is a relationship between colour and mood.
  • Devise an inquiry to determine whether people display similar emotional responses to subject matter presented in different forms; for example: photograph, painting, sketch, description, poetry, song.
  • Formulate a hypothesis and design an experiment to test whether chewing gum: improves concentration; decreases stress.
  • Provided with a set of data to visually recognise and identify outliers, discuss how these outliers would affect the validity of research and ways to manage through statistical analysis.
  • Bennett, Baird, Miller, and George (2009) conducted an fMRI on the brain of a dead salmon and activity was detected in the brain cavity. Discuss this research in terms of uncertainty and validity.
  • Hold a class discussion about the purpose of logbooks in psychology research.
  • Make a checklist of features that should be part of a scientific logbook (for example, dated and chronological).
  • Identify some of the assumptions or limitations of the following data generation techniques:

    • Using students’ English school reports to assess suitability for a trade
    • Asking managers to report on their own decision-making rationale during recruitment.
  • Access the research report on phobia’s effect on the perception of a feared object and evaluate the investigation methodology including any ethical implications. Design a different way to test the idea that the more afraid a person is of a spider, the bigger that individual perceives the spider to be.
  • Access a report of research undertaken related to a possible correlation between time spent outdoors and reduced incidence of high blood pressure and depression ​and identify and evaluate the limitations of the research study, including a discussion of repeatability, reproducibility and validity. Suggest modifications to the research methodology to improve the validity of the conclusions drawn from the results.
  • Make a checklist of things to consider when assessing the validity of a piece of psychological research.
  • Comment, in terms of the importance of scientific communication, on Anthony Hewish’s quote: ‘I believe scientists have a duty to share the excitement and pleasure of their work with the general public, and I enjoy the challenge of presenting difficult ideas in an understandable way’.
  • Carry out a web search for ‘poor data representations’. Look at several sites and create a list of important considerations when representing data visually (for example, always clearly label each axis).
  • Download and print prepared scientific posters (for example, from the University of Texas at Austin website. Work in groups and use a provided set of criteria to evaluate investigation aims, methodologies, data presentation, conclusions and effectiveness of scientific communication for each poster.
  • Hold small-group discussions in class to identify the strengths, weaknesses and areas for improvement of a range of scientific posters; for example, those found at the University of Texas at Austin website. Collate and reflect on class results and provided online evaluations to develop a set of ‘do’s’ and ‘don’ts’ for constructing a scientific poster.
  • Debate the topic: ‘It is more important, in presentations, to impress than to inform’.
  • Scientific posters are typically used at large conferences. With this in mind, discuss why poster conventions, word brevity and clear data analysis in graphs / tables is important.
  • Do a web search for ‘scientific poster’ images. Identify similarities in headings, layout and content. Identify differences in the posters and consider the features that enhance effective communication.
  • When looking at studies from a textbook or other sources, write a communication statement reporting the key finding of the investigation as a one-sentence summary (as per the scientific poster requirement).
  • Discuss the real-life implications of theories and models by discussing questions such as: For whom are these findings most relevant? How can these findings be used to advance society? Is there the potential for these findings to be applied in an unjust manner?

Scaffolding student designed scientific investigations

The type of guidance and the amount of support students will need to complete the Outcome 3 Scientific Investigation will vary greatly. Depending on your cohort, students may have already completed similar tasks and have a strong understanding of the scientific investigation process and the requirements of the scientific poster. Alternatively, you may have students who bring limited skills and knowledge or are completely new to the subject.

Early on in the year, one of the first things to do is estimate the knowledge and skills students currently have, both with and without guidance (their zone of proximal development). Based on this teachers can establish areas of focus (for example, formulating hypotheses or data analysis) and then review the unit to identify where such areas can be purposefully introduced. Then a series of collaborative learning activities, tools and reference resources can be developed to build up skills and knowledge. As student skill level increases the guidance can be gradually withdrawn.

A scaffolded approach may include:

Using a range of tools for students to access when developing knowledge and skills

For example: a template for writing hypotheses, a table to compare the advantages and limitations of different research designs, informed consent template, poster with some sections pre-populated as a cloze activity

Using a range of reference resources

For example: de-identified previous student posters, teacher created poster examples, single-page guide to descriptive statistics, guide to accessing secondary information including useful websites and advanced google searching tools, guide to reading and interpreting journal articles

Creating checklists with the class

For example: essential features of a hypothesis, things to consider when determining validity, graph and table requirements (for example, heading, axis labelled)

Teacher modelling a task, or sub-tasks, and then students working with teacher and each other to become more skilled

For example: teacher modelling how to turn a question into a hypothesis and then students working with each other and then individually to complete the same task.

For example: following a short classroom-based activity or experiment the teacher models how to complete data analysis such as identifying outliers, working out the mean, thinking aloud through the most appropriate way to present data and then completing a table or graph.

For example: teacher modelling how to read and interpret journal articles (for example, identify the specific question the research was trying to answer, scan the paper, focus on the abstract for a succinct summary, draw a diagram of the method).

Moving from structured teacher-led investigations to student-centered open investigations

Initially a teacher-led inquiry is carried out within the classroom and students complete a poster template with some sections pre-populated as a cloze activity (for example, experiment demonstrating the speed of neural transmission).

The next step may involve a structured inquiry with the teacher presenting a question and providing a prescribed procedure for the class to carry out. Students sample participants outside the classroom and then collate results before completing a poster template with reduced guidance (for example, a study to investigate the question ‘Does regular consumption of fermented foods influence stress levels?’).

The next step may involve a guided inquiry whereby the teacher chooses the question for investigation and the students work in one large group, or several small groups, to work with the teacher to decide how to proceed with the investigation. They may then complete the logbook entries and poster template with little, if any, guidance.

Finally, the students may carry out an open inquiry that begins with a student’s question, followed by the student (or groups of students) designing and conducting an investigation or experiment and communicating results.
