Fewer than you think. Around 32, if each one is chosen to work across more than one Area of Study.
There are 38 Areas of Study in the course. That does not mean 38 studies, and it certainly does not mean two or three per area. It means a smaller set of well-chosen evidence, used flexibly, plus a clear decision about which optional routes you are taking.
This article covers how to get the number down without leaving a gap in your syllabus coverage.
Why the number feels enormous
Two things inflate it.
The first is the assumption that every Area of Study needs its own dedicated study. It does not. Several studies sit naturally under more than one area, and once you notice which ones, the list shrinks fast.
The second is trying to prepare every optional route the syllabus offers. This is the bigger problem, and it is entirely avoidable.
One well-prepared option is enough
Where the syllabus offers you a choice, you take one. That is the rule, and it changes your workload more than any study technique will.
You do not need:
- two mental health disorders
- two health problems
- two developmental domains
- both types of interpersonal relationship
- two cognitive processes
Choosing one route deliberately, and committing to it in writing, lets you learn less and use what you know more flexibly. Half-preparing three options is the most common way to end up with a lot of hours spent and no area covered to top-band depth.
Where breadth genuinely is compulsory
A handful of areas contain more than one required part, and these are worth checking against your own notes now rather than in May.
- Cultural differences in mental health. Both prevalence differences and differences in approaches to mental health.
- Prevalence of a health problem. Change within populations and differences between populations.
- Brain development. Maturation, critical periods and neuroplasticity.
- Stage theories and continuous models. A stage account and a continuous account.
- Development of self. All four Areas of Study.
- Group behaviour. All six Areas of Study.
- Acculturation. Different strategies, not just one.
- Conditioning. Classical and operant, plus an application of operant conditioning.
- Social identity theory. Explain group behaviour, and change it.
- Social learning theory. Explain learning, and apply it to change behaviour.
- Cognitive models of memory. Two models are compulsory.
Everywhere else that offers a choice, one option is enough.
One study, several areas
The way to keep the number low is to choose evidence that earns its place more than once.
Caspi et al. covers both biological explanations of major depressive disorder and environmental factors in it. Maguire can be used for neuroplasticity and, reused carefully, for brain development. Loftus and Palmer sits under schema theory and under environmental influences on cognition. Bartlett sits under schema theory and cultural factors in cognition. Bandura appears in learning and cognition and again in human relationships.
That reuse is the whole trick. Around 32 studies can cover all 38 Areas of Study if you pick them for range rather than one at a time.
One warning that comes with it. If a study covers two areas, the emphasis each area needs is different. Social learning theory in learning and cognition is about learning as a process and the contrast with conditioning. In human relationships it is a different argument. Same evidence, different essay.
Three kinds of evidence, and why the difference matters
This is the part most revision guides skip, and it is the difference between an answer that sounds evidenced and one that actually is.
Every study you use relates to its topic in one of three ways, and examiners can tell them apart.
| Status | What it means |
|---|---|
| Direct evidence | The study actually investigated this phenomenon |
| Reused support | The study gives a relevant mechanism or finding, but was conducted in another content area |
| Content or application | You need psychological theory or a clear example here. No named study is required |
Do not present all three as if they are equivalent, and never imply a study tested something its design did not test.
Match the verb to what the evidence can carry:
| Write this | When |
|---|---|
| "The study demonstrates..." | The finding is direct |
| "The findings are consistent with..." | The link is inferential |
| "The design cannot establish..." | You are reaching the concept through a limitation |
| "This evidence can be paired with..." | Another study is needed to complete the point |
| "The theory suggests..." | You are applying theory rather than reporting a result |
The test to run on every sentence
Do not write "the study shows" unless the study actually shows it.
Before you keep a sentence, ask what an examiner would ask: but did this study actually test that?
If the sentence collapses under that question, rewrite it. Usually the fix is one verb.
This single habit does more for Section C credibility than adding another study to your list, because it is the difference between using evidence and gesturing at it.
What "study details are not assessed" changes
In Paper 1 Section C, knowledge of the specific details of research studies is not assessed.
That does not make studies useless. It means the marks come from conceptual understanding and critical thinking, and that a named study is the most reliable way to be specific rather than vague.
So learn each study to a particular depth and stop there. Aim, method, finding, one strength, one limitation, and what it does and does not license. Nobody is checking the year or the number of participants.
If you can explain what a study showed, how it showed it, and what it does not establish, you have everything Paper 1 needs from it.
What to do this week
Write down your route. One page. For every Area of Study that offers a choice, name the option you are taking. For every area on the compulsory-breadth list above, check you have both parts.
Then list your evidence and mark each entry with which areas it covers. Anything covering only one area, in a place where an alternative could cover two, is a candidate for replacement.
You will almost certainly find you are carrying studies you do not need and missing one or two of the compulsory second parts. Both are cheap to fix now and expensive to discover in May.
If you want that route mapped out already, with 32 studies chosen for range, all six concepts written for each one, and a coverage map showing which of the 38 areas each study serves, that is what the PsychExcel Paper 1 Study Bank is for.
