Mark it yourself: QCE Psychology short responses
QCAA Psychology marks are itemised: one mark for each concept explained, each example given, each trend identified, each piece of supporting data, and each step in using statistics. Count the elements the question asks for before you write, and check them off when you mark.

How to use this pack
QCAA marking guides break every short-response question into separate marks. Once you can see those elements, you can mark your own answers almost exactly as a marker would. This pack uses the 2024 Psychology external assessment marking guide to show how four common question types are marked. Each type has an original practice question with our own full-mark sample answer (written by ExamExplained, not an official QCAA response), the errors that cost marks, and a self-marking prompt.
These examples come from the 2024 external assessment. QCAA has introduced new senior syllabuses, so check QCAA's current syllabus and assessment information for your cohort; the way marks are matched to elements of a response is the part to learn from here.
How the QCAA Psychology marking guide works
- One element, one mark. For example, 2024 Paper 1 Question 21: "describes learned fear in the context of classical conditioning [1 mark]", "identifies the conditioned stimulus as the white rat [1 mark]", "identifies the unconditioned stimulus as the loud noise [1 mark]".
- Explanation and example are separate marks. Question 28b gave a mark for explaining each of negative reinforcement, positive reinforcement and punishment, and another mark for an example of each: 6 marks in total.
- Claims need data. Paper 2 Question 1b paired "identifies the trend" with "provides evidence to support the trend" for each measure.
- Statistics are marked step by step. Question 6d gave separate marks for the maximum of the lesser mean, the minimum of the greater mean, whether the intervals overlap, and the conclusion.
Type 1: explaining a theory with examples (3 to 6 marks)
Official pattern (2024, Paper 1, Question 28b): "explains use of negative reinforcement [1 mark], positive reinforcement [1 mark], punishment [1 mark]"; "provides an example of negative reinforcement [1 mark], positive reinforcement [1 mark], punishment [1 mark]".
| Marks | Element |
|---|---|
| 1 each | Each process or concept explained accurately |
| 1 each | Each linked to a specific example from the scenario |
Practice question (ours). Jess, aged 15, starts vaping after seeing older students at her school vaping and being admired by their friends. Explain how social learning theory accounts for Jess's behaviour, referring to attention, retention, reproduction and motivation. (4 marks)
Our sample answer (4 marks).
- Attention: Jess noticed the older students' vaping because they were high-status models whom she saw often and wanted to be like.
- Retention: she stored a mental representation of what they did, such as how they held and used the vape, so that she could recall it later.
- Reproduction: Jess had access to a vape and the ability to copy the behaviour, so she could reproduce what she had observed.
- Motivation: she saw the models being admired by their friends (vicarious reinforcement), so she expected that vaping would bring her the same social approval, which motivated her to perform the behaviour.
Defining the four processes in general terms without mentioning Jess, the older students or the admiration. When a scenario is given, each mark depends on linking the concept to it.
Type 2: identifying trends and supporting them with data (4 marks)
Official pattern (2024, Paper 2, Question 1b): "identifies the trend in rate of response [1 mark], response time [1 mark]"; "provides evidence to support the trend in rate of response [1 mark], response time [1 mark]". The sample response quoted the values at both ends of the range.
Practice question (ours). Participants learned a list of 20 words, rehearsing each word a set number of times, and then recalled the list and rated their confidence.
| Rehearsals per word | 1 | 3 | 5 | 7 |
|---|---|---|---|---|
| Mean words recalled (out of 20) | 6 | 9 | 12 | 13 |
| Mean confidence rating (1 to 10) | 4 | 6 | 8 | 9 |
Identify the trend in each measure and support each trend with data. (4 marks)
Our sample answer (4 marks).
- Recall increased as the number of rehearsals increased. With one rehearsal per word, participants recalled a mean of 6 words; with seven rehearsals, a mean of 13 words.
- Confidence also increased as the number of rehearsals increased, from a mean rating of 4 with one rehearsal to 9 with seven rehearsals.
Describing the trend with no numbers ("recall went up"). The evidence mark needs specific values, ideally from both ends of the data.
A detail worth noticing: recall rose by 3 words between 1, 3 and 5 rehearsals but by only 1 word from 5 to 7. If a question asked you to describe the relationship in more detail, noting that the increase levels off would show closer analysis.
Type 3: drawing a conclusion and considering an alternative explanation (4 marks)
Official pattern (2024, Paper 2, Question 4): 4b "draws a conclusion [1 mark]" and "provides evidence to justify the conclusion [1 mark]"; 4c "infers an explanation other than level of processing that is consistent with the finding [1 mark]" and "supports response with data [1 mark]".
Practice question (ours). Students studied a passage in one of three conditions and were then tested.
| Condition | Mean recall score (out of 20) | Mean time spent studying (minutes) |
|---|---|---|
| Silence | 14.0 | 20 |
| Instrumental music | 13.4 | 20 |
| Music with lyrics | 10.2 | 16 |
(a) Draw a conclusion about the effect of music on recall, and justify it with data. (2 marks)
(b) Suggest an alternative explanation for the result in the lyrics condition, and support it with data. (2 marks)
Our sample answer (4 marks).
(a) Music with lyrics reduced recall, while instrumental music had little effect. Students who studied with lyrics recalled a mean of 10.2, compared with 14.0 in silence and 13.4 with instrumental music.
(b) Students in the lyrics condition also spent less time studying (a mean of 16 minutes, compared with 20 minutes in the other two conditions), so the lower recall could be due to less time rehearsing the material rather than to the lyrics themselves.
Offering an alternative explanation that the data cannot support ("maybe they were tired"). The mark requires an explanation "consistent with the finding" and supported with data from the stimulus.
Type 4: using confidence intervals to reach a conclusion (4 marks)
- Official pattern (2024, Paper 2, Question 6d)
- "uses confidence intervals to determine the maximum value of the lesser mean [1 mark]"; "uses confidence intervals to determine the minimum value of the greater mean [1 mark]"; "determines that the intervals do not overlap [1 mark]"; "concludes that context-dependent cues affect memory [1 mark]".
- Practice question (ours)
- In a study of the effect of sleep on memory, participants who slept after learning had a mean recall of 9.6 (95% confidence interval ±0.8), and participants who stayed awake had a mean recall of 8.1 (95% confidence interval ±0.9). Use the confidence intervals to determine whether sleep affected recall. (4 marks)
- Our sample answer (4 marks)
- Maximum value of the lesser mean (stayed awake): 8.1 + 0.9 = 9.0.
- Minimum value of the greater mean (slept): 9.6 - 0.8 = 8.8.
- The intervals overlap, because 9.0 is greater than 8.8.
- Therefore we cannot conclude that sleep affected recall; the difference between the means may be due to chance.
Concluding that sleep improved memory because 9.6 is higher than 8.1. When intervals overlap, the difference in means is not enough evidence of an effect. Notice that this practice question reaches the opposite conclusion to the 2024 QCAA question: always calculate.
