Mark it yourself: VCE Psychology short answers and the 10-mark extended response

How to use this pack

VCE Psychology's Section B is worth 80 of the exam's 120 marks, and it rewards precise terminology applied to the scenario in front of you. This pack draws on the VCE Psychology examination specifications and the 2025 VCE Psychology external assessment report to show how four question types are assessed. Each type has an original practice question with our own high-scoring sample answer (written by ExamExplained, not an official VCAA response), the errors that cost marks, and a self-marking prompt.

How VCE Psychology answers are assessed

• Short answers are marked against expected points. The report lists what full-mark answers "were required to" include. For example, a 3-mark predict-and-justify question in 2025 required the prediction, a justification and a link to the measure used.
• Context is part of the mark. For 2025 Question 8 (5 marks), "Students could access a maximum of four marks (out of a possible five) if their answer was generic/non-contextual and did not mention the pencil-holding scenario."
• The 10-mark question has published criteria. The examination specifications state that it is assessed against: "identification and explanation of appropriate psychological terminology in novel and unfamiliar contexts"; "analysis and discussion of relevant psychological information, ideas and/or concepts and the connections between them"; "analysis and evaluation of data, and/or scientific methodologies and methods, and/or models, and/or theories"; and "construction of evidence-based arguments and/or drawing of conclusions and/or discussion of implications and findings".
• Command terms guide the length. The report reminds students to use the VCAA glossary; for example, "'summarise' requires a concise account of relevant and major details".

Where we describe marks point by point below, it is our interpretation of the report's lists, not an official VCAA scheme.

Type 1: explaining a concept in context (4 to 5 marks)

What the report says. 2025 Question 8 asked how long-term potentiation and long-term depression work together as a child learns to hold a pencil. Full marks required accurate definitions of both, the physical mechanisms (sprouting or rerouting, and pruning), and how they "work together" in the scenario. Common errors included explaining that the new grip "would simply replace the old grip" without the neural level, and "stating that long-term depression involves no stimulation/neural firing, which is inaccurate."

Practice question (ours). Eight months ago, Tom was trapped for an hour in a lift that stopped between floors in the dark. He now feels intense fear whenever he approaches any lift, and always takes the stairs, even to the tenth floor. Explain how classical conditioning and operant conditioning could account for the development and continuation of Tom's fear of lifts. (4 marks)

Our sample answer (full marks).

• Development (classical conditioning): being trapped in the dark was an unconditioned stimulus that produced fear as an unconditioned response. The lift, previously a neutral stimulus, was paired with this experience, so it became a conditioned stimulus that now triggers fear (the conditioned response) whenever Tom approaches any lift.
• Continuation (operant conditioning): each time Tom avoids a lift by taking the stairs, his anxiety is removed. Because removing an unpleasant stimulus increases the behaviour that led to it, this is negative reinforcement, so Tom's avoidance becomes more likely.
• Because Tom always avoids lifts, he never experiences the lift without anything bad happening, so the conditioned fear is never extinguished and the phobia continues.

Type 2: research-methods questions (2 to 3 marks)

What the report says. For the 2025 hypothesis question, "both levels of the independent variable were required in the hypothesis, and the dependent variable needed to refer to" the measure being studied; "Lower-scoring responses were typically not phrased as a hypothesis with a clear prediction." For a question on why a correlational study would be more ethical than an experiment, the report noted that some responses "explained possible ethical issues of a controlled experiment rather than why a correlational study may be a more ethical" methodology: they did not answer the question asked.

Practice question (ours). Researchers want to know whether using a phone in the 30 minutes before bed affects how long Year 12 students take to fall asleep. Forty Year 12 students are randomly allocated to use their phone for 30 minutes before bed, or to read a paper book for 30 minutes before bed, for two weeks. Each student records the time taken to fall asleep in a sleep diary.

(a) Write a hypothesis for this study. (2 marks)
(b) Identify one extraneous variable and explain how the researchers could control it. (2 marks)

Our sample answer (full marks).

(a) It is hypothesised that Year 12 students who use a phone for 30 minutes before bed will take longer to fall asleep, as recorded in a sleep diary, than Year 12 students who read a paper book for 30 minutes before bed.

(b) Caffeine intake could affect how long students take to fall asleep, independently of phone use. The researchers could control it with standardised instructions telling all participants not to consume caffeine after midday during the study, and ask them to record any caffeine in their diary.

Other common errors: naming the independent variable as an extraneous variable; "control it by keeping it the same" with no method; confusing random allocation (to groups) with random sampling (from a population).

Type 3: predict and justify (2 to 3 marks)

What the report says. 2025 Question 6e asked students to predict how frequent electronic device use before bed would change a sleep-quality score and justify it. Full marks required the correct prediction, a justification through "melatonin suppression or disrupted sleep onset", and a link to poorer sleep quality. Common errors included "not referring to the ASBQ score at all" and "confusing the ASBQ direction".

Practice question (ours). In a laboratory study, students complete a 10-minute sustained-attention task in which they press a button whenever a light appears. The score is the number of missed responses. Predict how a week of sleeping only five hours a night would affect a student's score, and justify your prediction. (3 marks)

Our sample answer (full marks).

The student's number of missed responses would increase. A week of five-hour nights is partial sleep deprivation, which impairs cognitive functioning, including the ability to sustain attention and react quickly, and causes brief lapses in concentration. Because the task requires continuous attention to detect each light, these lapses would cause more lights to be missed, raising the student's score.

Type 4: the 10-mark extended response

The criteria. The four published criteria (above) are applied holistically. For 2025 Question 9, which asked students to compare two mnemonics using a diagram and evaluate them for a person with aphantasia, the report said the question "rewarded reasoning rather than long narrative writing", and that high-scoring responses "demonstrated clear use of psychological terminology, strong comparative analysis, explicit reference to the diagram, and justified evaluative reasoning. Responses using paired comparisons, direct quotes and because-statements often scored highly." Common errors included "only defining terms rather than using them functionally" and "listing general statements without elaboration".

Practice question (ours, with hypothetical data). A boarding school proposes banning phone use in the hour before its 9:30 pm lights-out to improve students' sleep and wellbeing. It surveyed 60 boarders about their usual phone use and sleep.

Using the data and your knowledge of psychology, evaluate the school's proposal. (10 marks)

Our sample answer (high-scoring).

The data suggest the proposal is likely to improve boarders' sleep, although the survey cannot prove that phone use causes poor sleep.

There is a clear pattern: as phone use in the hour before lights-out increases from 5 to 55 minutes, mean sleep onset latency almost triples (15 to 42 minutes) and total sleep falls by 1.5 hours (8.1 to 6.6 hours). Group C's 6.6 hours is well below the 8 to 10 hours generally recommended for adolescents, meaning these boarders are likely to be experiencing partial sleep deprivation, with effects on concentration, mood and wellbeing.

Psychology offers a plausible mechanism. Light from phone screens is detected by the retina and signalled to the suprachiasmatic nucleus, which acts on the pineal gland to suppress melatonin, the hormone that promotes sleepiness. Because adolescents already experience a delay in the timing of melatonin release, evening screen light may push sleep onset even later. Engaging content also increases arousal, and time on the phone may simply displace sleep. A ban would therefore remove an unhelpful zeitgeber at the wrong time of day and support better sleep hygiene.

However, the evidence has important limitations. The survey is correlational: the school did not manipulate phone use, so a third variable could explain both patterns. For example, boarders who are stressed or anxious might both use their phones more and take longer to fall asleep. The data are self-reported, so phone use and sleep may be misremembered or under-reported. The groups are also small (20 per group) and come from one school, limiting generalisation.

The proposal's effect on wellbeing is less certain than its effect on sleep. For boarders, phones may be a main source of social support from family and friends, a protective factor for mental wellbeing, so a ban could increase stress for some students. Allowing phone contact earlier in the evening would address this.

Overall, the proposal is well supported as a way to improve sleep, because the data show a consistent relationship and the melatonin mechanism explains it. To confirm that the ban causes the improvement, the school could run a trial, randomly allocating houses to the ban or to their usual routine, and measure sleep with sleep diaries or wearable devices before adopting it permanently.

Why it scores highly: terminology is used to explain, not just define; figures from the table are quoted; the mechanism and the limitations are connected with "because"; the design (correlational, self-report, sample) is evaluated; and the conclusion is a justified judgement with a practical implication.

Errors that hold extended responses back:

• Narrative instead of reasoning. Retelling the scenario earns little; every paragraph needs a concept, a link and evidence.
• No figures from the stimulus. The criteria reward analysis of the data provided.
• Causal claims from correlational data.
• No judgement. "Evaluate" requires a conclusion about the proposal.
