The two formats — essay vs empirical report
Most UK psychology modules assess you with one of two formats, and they require fundamentally different skills.
The discursive essay asks you to evaluate theory, weigh evidence, and reach a conclusion on a debated question. "Critically evaluate the cognitive theory of depression" or "To what extent does attachment style predict adult relationships?" These are essentially extended literature reviews where you build an argument from published research.
The empirical report describes a study you've conducted (or analysed). It follows a strict scientific format known as IMRaD: Introduction, Methods, Results, Discussion. Lab reports, dissertation chapters, and many second-year practical assignments use this structure.
Most students are stronger at one format than the other. The trap is approaching them the same way. A good essay reads like an argument; a good report reads like a precise scientific record. Mixing the styles — adding rhetorical flourishes to a methods section, or burying findings in narrative — costs marks in both directions.
Discursive essay structure
A psychology essay isn't just a literature summary. UK marking criteria explicitly reward critical evaluation, theoretical engagement, and original synthesis. Description gets you a 2:2 ceiling no matter how thorough.
Introduction
Three things in 150–200 words: define your terms (what does "depression" mean in this essay — major depressive disorder per DSM-5? subclinical symptoms? something else?), state your argument or position, and signal the structure of what follows. Avoid sweeping openings about how depression is "a major problem in society" — your marker has read it 50 times this week.
Body — theme by theme, not study by study
The single biggest structural mistake UK psychology students make is organising their essay around studies rather than themes. A 2:2 essay reads: "Beck (1967) argued X. Then Abramson (1989) argued Y. Then Joiner (2005) argued Z." Each paragraph summarises a study. The essay becomes a list.
A 2:1 or First-class essay organises around themes or arguments. "One strand of research emphasises cognitive vulnerability (Beck, 1967; Abramson et al., 1989), but a competing tradition prioritises social context (Brown & Harris, 1978)." Now you're synthesising. The same studies appear, but they're being used to build an argument rather than padding a chronology.
Critical evaluation — where the marks live
For each major piece of evidence you cite, briefly evaluate it. Was the sample representative? Were the measures valid? Has it replicated? Don't just say "this study has limitations" — name them and explain why they matter for your argument. Specific critiques get marks; generic ones don't.
"Beck's cognitive triad has been criticised" is a 2:2 sentence. "Beck's cognitive triad relies heavily on retrospective self-report, which is problematic given that depressive episodes are known to bias autobiographical memory (Williams & Scott, 1988) — meaning the data ostensibly supporting the theory may itself be a product of the cognitive distortions the theory predicts" is a First-class sentence. Both make the same point. The second shows you understand why the criticism matters.
Conclusion
Answer the essay question directly. Not "this essay has discussed…" but "the evidence suggests that cognitive theories provide a partial but incomplete account of depression onset, with the strongest support emerging from studies that integrate cognitive and contextual factors." Take a position. Defend it briefly. Done.
Empirical report structure (IMRaD) with worked examples
Empirical reports follow a fixed structure. Deviations almost always cost marks. The structure exists because scientific reporting needs to be replicable — a reader should be able to follow the logic from research question through to interpretation without ambiguity.
Length: typically 15–20% of your word count for an undergraduate report. Don't over-extend — a tight, focused introduction beats a sprawling literature review every time.
Hypotheses must be testable. "Participants will perform better on the recognition task" is too vague. "It is predicted that participants in the deep encoding condition will recall significantly more words than participants in the shallow encoding condition" is testable.
Design: Name your design type (independent measures, repeated measures, mixed). State your IV and DV, identify levels of each.
Participants: Number, demographics (age range and mean, gender breakdown), recruitment method, any inclusion/exclusion criteria. UK reports typically use BPS-approved language — "participants" not "subjects".
Materials: Every stimulus, questionnaire, or piece of equipment used. For standardised measures (e.g., Beck Depression Inventory), cite the original publication and report the reliability coefficient if available.
Procedure: Step-by-step description in past tense. Counterbalancing, instructions to participants, timing, debrief — all included.
Use past tense throughout methods. Not "participants are asked to" but "participants were asked to".
Standard order: descriptive statistics first (means, SDs, often presented in a table), then inferential statistics (the test you ran, the result, whether it was significant). Report effect sizes alongside significance — APA 7th expects this.
Tables and figures need to be self-explanatory. A reader should understand them without referring back to the text. This means full table titles, clearly labelled axes, and notes explaining any abbreviations.
Don't repeat in prose what's already in a table. Reference the table, summarise the key pattern, move on. "As shown in Table 1, the deep encoding group (M = 12.3, SD = 2.1) recalled more words than the shallow encoding group (M = 7.8, SD = 1.9)" is correct. Listing every cell again in sentences is padding.
Relate to literature. Don't just describe what you found — connect it to the studies you cited in your introduction. Did your results replicate Craik & Lockhart (1972)? Extend them? Contradict them? Explicit comparison is what markers want to see.
Limitations should be specific and honest. "The sample was small" is generic. "The sample (N = 24) is underpowered for detecting interaction effects, which may explain the non-significant results for H2" is specific and analytical. Don't apologise for limitations — explain what they mean for the interpretation of your findings.
Future research should follow logically from your specific findings, not be a generic "more research is needed" statement. What study would you run next, and why?
How to report statistics in APA 7th
UK psychology programmes follow APA 7th edition for statistical reporting. Get this wrong and you lose marks regardless of how good your analysis is. Here are the conventions that catch UK students out:
Italicise statistical symbols: M, SD, t, F, r, p, n, N. They're variables, so they're italicised. Numbers themselves are not italicised.
Don't put a leading zero before p or r — these can never exceed 1. So p = .03, not p = 0.03. Same for r, η², and other values bounded by 1.
Report exact p values to three decimal places, except when very small. So p = .024, not p < .05. The exception is when p is below .001 — then write p < .001.
Always include effect sizes. APA 7th requires this. For t-tests, report Cohen's d. For ANOVAs, report partial eta-squared (η²p). For correlations, the r value is itself the effect size.
Standard format for inferential statistics:
Worked example: "There was a significant effect of encoding condition on recall, t(46) = 4.32, p < .001, d = 1.24, with the deep encoding group (M = 12.3, SD = 2.1) recalling more words than the shallow encoding group (M = 7.8, SD = 1.9)."
That sentence does five things at once: states the test, reports the result, provides effect size, gives descriptive statistics for both conditions, and indicates direction. That's APA 7th done properly.
APA 7th referencing — the rules that catch UK students out
APA 7th is detailed, but the basics aren't difficult once you understand the logic. The rules that consistently trip UK psychology students up:
Up to 20 authors get listed in the reference list (in APA 7th — earlier editions cut off at 7). For 21+, list the first 19, an ellipsis, then the last author. In-text citation rules are different: 3+ authors get "et al." from the first citation, not the second.
DOIs are formatted as URLs, not as "doi:" prefixes. So https://doi.org/10.1037/abc1234, not doi:10.1037/abc1234. APA 7th changed this from the 6th edition.
Journal article format:
Book format:
Note: APA 7th removed the publisher location (no more "Hove: Routledge" — just "Routledge"). This is different from earlier editions and from Harvard, which still requires location.
Edited book chapter format:
SafeGrade's citation checker validates APA 7th formatting. If your reference list has the wrong DOI format or missing italics, it'll flag every error so you can fix them before submission. Marker patience for citation errors in psychology is famously low — these are easy marks to lose.
5 mistakes that drop psychology grades
1. Writing the methods in present tense. Methods describes what you did, in the past. "Participants are asked to complete a memory task" is wrong. "Participants were asked to complete a memory task" is right. This is the most common preventable mistake in first-year reports.
2. Confusing significance with effect size. A statistically significant result with a small effect size is often less practically meaningful than a non-significant result with a moderate effect size. Markers want to see that you understand this distinction. Don't write "the result was highly significant (p < .001)" without commenting on whether the effect size is meaningful.
3. Causal claims from correlational data. If your study is correlational, you cannot conclude that one variable causes another — only that they're associated. "These results show that anxiety causes poor exam performance" from a correlational study is a major error that markers will pounce on. Use language like "associated with" or "predicts" instead.
4. Treating the discussion as a recap. The discussion is for interpretation, not summary. Restating findings is fine in the opening sentence, but if your entire discussion describes what you found rather than what it means, you're capping your grade. Markers want analysis, not a second results section.
5. Generic future research suggestions. "Future research could replicate this with a larger sample" applies to every psychology study ever conducted. It tells markers you ran out of ideas. Specific suggestions — "future research could examine whether this effect persists in clinically depressed samples, given that our undergraduate sample's depression scores were within the non-clinical range" — show genuine engagement with your own findings.
Psychology essays and reports reward precision. The students who get Firsts aren't necessarily writing more eloquently than 2:1 students — they're being more accurate, more specific, and more analytically careful. SafeGrade's grade estimator is calibrated to UK psychology marking conventions, and Sage gives discipline-specific advice on IMRaD structure, APA formatting, and the kind of critical evaluation language that pushes a 2:1 essay into First territory.
