VCE Psychology: complete 2026 guide to Units 3 and 4 (study design from 2023)

VCE Psychology Units 3 and 4 are the Year 12 sequence under the VCAA study design implemented from 2023. Unit 3 asks how experience affects behaviour and mental processes; Unit 4 asks how mental wellbeing is supported and maintained. Together they produce a VCE study score.

This page is the index. Below you will find every dot-point answer we have for VCE Psychology in 2026, organised by unit and area of study, with the assessment structure taken from the study design and the VCAA examination specifications.

The five areas of study

Unit 3: How does experience affect behaviour and mental processes?

• Area of Study 1: How does the nervous system enable psychological functioning? Nervous system functioning (subdivisions of the nervous system, conscious and unconscious responses, neurotransmitters and neuromodulators, synaptic plasticity), and stress as an example of a psychobiological process (stressors and stress responses, cortisol, the gut-brain axis, the General Adaptation Syndrome, the Transactional Model, and coping strategies).
• Area of Study 2: How do people learn and remember? Approaches to understand learning (classical and operant conditioning, observational learning, and Aboriginal and Torres Strait Islander ways of knowing) and the psychobiological process of memory (the Atkinson-Shiffrin model, the brain regions of long-term memory, episodic and semantic memory, and mnemonics including songlines).

Unit 4: How is mental wellbeing supported and maintained?

• Area of Study 1: How does sleep affect mental processes and behaviour? The demand for sleep (REM and NREM, measurement, regulation by the suprachiasmatic nucleus and melatonin, sleep across the life span) and the importance of sleep to mental wellbeing (partial and full sleep deprivation, circadian rhythm sleep disorders, bright light therapy, sleep hygiene and zeitgebers).
• Area of Study 2: What influences mental wellbeing? Defining mental wellbeing (levels of functioning, resilience, SEWB, the continuum), a biopsychosocial approach to specific phobia (development and evidence-based interventions), and the maintenance of mental wellbeing (protective factors and cultural determinants).
• Area of Study 3: How is scientific inquiry used to investigate mental processes and psychological functioning? A student-designed investigation generating primary quantitative data, presented as a scientific poster with a logbook.

Unit 3 dot-point guides

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

• Neurons and the nervous system

• Stress, GAS and the Transactional Model
• The gut-brain axis and stress
• Coping strategies and coping flexibility

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

• Classical and operant conditioning
• Observational learning
• Aboriginal and Torres Strait Islander ways of knowing
• The Atkinson-Shiffrin multi-store model of memory
• Brain regions in long-term memory
• Episodic and semantic memory and imagining the future
• Alzheimer's disease and aphantasia
• Mnemonics and Aboriginal songlines

Unit 4 dot-point guides

Area of Study 1: How does sleep affect mental processes and behaviour?

• Sleep stages, REM and NREM, and sleep across the life span
• Sleep regulation, sleep deprivation and BAC
• Circadian rhythm sleep disorders and bright light therapy
• Improving sleep-wake patterns: sleep hygiene and zeitgebers

Area of Study 2: What influences mental wellbeing?

• Ways of considering mental wellbeing and the SEWB framework
• Mental wellbeing continuum and specific phobia
• Protective factors for maintaining mental wellbeing

Area of Study 3: How is scientific inquiry used to investigate mental processes and psychological functioning? (key science skills)

• Research methods and investigation design
• Ethical concepts and guidelines in research
• Data analysis and evaluating research
• The student-designed investigation and scientific poster

Assessment structure (Units 3 and 4)

From the study design:

• Unit 3 School-assessed Coursework: 20 per cent. Outcome 1 (nervous system and stress) and Outcome 2 (learning and memory), 40 marks each. Each is one task chosen from: analysis and evaluation of a case study, experiment, model or simulation; analysis and evaluation of primary and/or secondary data; comparison and evaluation of three student practical activities; or analysis and comparison of two or more contemporary media texts. Each task type can be used only once across Units 3 and 4.
• Unit 4 School-assessed Coursework: 30 per cent. Outcome 1 (sleep) and Outcome 2 (mental wellbeing), 40 marks each, from the same list of task types, plus Outcome 3 (40 marks): a student-designed investigation communicated as a scientific poster of no more than 600 words, with logbook entries.
• End-of-year examination: 50 per cent. From the VCAA examination specifications: 15 minutes reading and 2 hours 30 minutes writing, 120 marks. Section A is 40 multiple-choice questions (40 marks). Section B is short-answer and extended-answer questions (80 marks), including one 10-mark extended-answer question without parts, assessed against four criteria: terminology in novel contexts, analysis of concepts and their connections, evaluation of data, methods, models or theories, and evidence-based argument. On our 2026 timetable data the exam is on Friday 30 October 2026.

Study strategy

Learn the key knowledge in VCAA's words

Examiners' reports repeatedly reward the study design's definitions (for example, integrity, repeatability, primary and secondary appraisal) and the named components of each model. Each of our dot-point pages quotes the key knowledge it covers.

Classify before you explain

Most questions are scenarios. Decide the category first (explicit or implicit memory, neurotransmitter or neuromodulator, biological, psychological or social factor, repeatability or reproducibility), then apply it to the details given.

Treat the key science skills as a unit of content

They are examinable in every paper and underpin the Unit 4 poster. Work through the four Area of Study 3 pages early, then practise them on every past paper you do.

Write congruent comparisons

When asked to compare or contrast, write each point about the same feature for both things. Mismatched features lose marks every year.
