How to Memorise Psychology Studies for Exams (4-Line Method)

Quick answer: To memorise psychology studies, compress each one to four lines — aim, method, findings with a real number, and one evaluation point — then recall it onto a blank page instead of rereading it. Twenty to twenty-five studies at four lines each covers most of a GCSE, Cambridge or AP psychology paper.

I do not sit Psychology myself — I am doing IGCSE and A-Levels, and my own papers are history and English. But a friend takes Cambridge AS Psychology and was trying to learn twenty-odd core studies by rereading the same textbook pages. It was not working. What I am good at is memorising history evidence, so we rebuilt her studies as evidence cards. Two weeks later she could write the findings of every core study from a blank page. Here is what we did, including what I got wrong first.

What a named study is actually worth in the mark scheme

A named study is evidence, and it pays you twice: once when you describe it accurately, and again when you use it to support or attack a claim.

That second use is where marks go missing. Learn a study only as description and an evaluate question leaves you with nothing but "the sample was small". A study you cannot argue with is half a study.

The boards want slightly different things, and it changes the card:

• Cambridge AS and A Level Psychology names its core studies in the syllabus, so procedure detail is genuinely examinable, not decoration.
• AQA and Edexcel GCSE Psychology name key studies per topic. You need enough method to describe one in four sentences and criticise it in one.
• AP Psychology now gives you a research description in the free-response section and asks you to analyse it, so the higher-value skill is research-methods vocabulary: operational definition, random assignment, confounding variable, sampling bias.
• CBSE Class 12 Psychology leans on concepts and applied examples rather than named procedures, so the card becomes definition, example, application.

The four-line study card

Four lines. Never a paragraph.

1. Aim — the question it tried to answer, in under twelve words.
2. Method — one sentence containing the sample size and the one thing that was changed between groups.
3. Findings — one sentence containing at least one real number.
4. Evaluation — one sentence naming a weakness and why that weakness matters for the conclusion.

Here is a full card for Loftus and Palmer, an eyewitness testimony study used across GCSE and Cambridge specifications:

• Aim: does the wording of a question change what someone remembers about an event?
• Method: 45 participants watched seven film clips of car crashes, then estimated speed, with only the verb in the question swapped between groups (smashed, collided, bumped, hit, contacted).
• Findings: mean estimates ran from 40.8 mph for "smashed" down to 31.8 mph for "contacted". In the follow-up with 150 participants, 16 out of 50 in the smashed group later said they had seen broken glass, against 7 out of 50 in the hit group — and there was no broken glass in the film.
• Evaluation: participants watched clips knowing they would be tested, so the stress of a real crash is missing, and the leading-question effect may be weaker with genuine witnesses.

The number in line three is load-bearing. "Participants gave higher estimates" is guessable. "40.8 mph against 31.8 mph" reads like you know the study.

Two more in the same shape. Asch: 123 male students agreed with an obviously wrong group answer on 36.8 percent of critical trials, and about 75 percent conformed at least once, against under 1 percent errors when answering alone. Milgram: 40 men, every one of whom continued to 300 volts, with 65 percent going to the maximum 450.

Worked example: one card, three questions

The same four lines answer a describe question, a limitation question and an application question. You just choose which lines to use.

A 4-mark "describe one study into the accuracy of eyewitness testimony" uses lines one to three:

Loftus and Palmer wanted to know whether the wording of a question could change what people remembered. Forty-five participants watched film clips of car crashes and estimated how fast the cars were going, with one verb in the question changed between groups. Those asked about the cars that smashed gave a mean estimate of 40.8 mph, compared with 31.8 mph for contacted.

A 3-mark "explain one limitation" uses line four, opened out into three clauses:

One limitation is that the study lacks ecological validity. Participants watched short clips knowing they were about to be tested, rather than witnessing a real crash with the shock that involves. This matters because real witnesses may be harder to mislead than the results suggest, so the findings may overstate how unreliable testimony is in court.

An application question — an officer asks how fast the car was going when it smashed into the wall — uses line three as evidence and line four as the caution: name the leading verb, predict an inflated estimate, suggest neutral wording.

On timing, a 6-mark evaluate question at GCSE is worth roughly six to eight minutes. One point developed across three clauses beats three that stop after one.

The evaluation line is where the marks hide

Most lost evaluation marks come from points that stop halfway. Three clauses, every time: state the point, anchor it in a specific detail of that study, then say what it does to the conclusion.

Weak version: "The sample was biased." Full version: "All 40 participants were men recruited by newspaper advert in one American city, so we cannot assume women or people in other cultures would obey at the same rate, which limits how far the 65 percent figure generalises."

Five angles cover nearly everything: sample, setting, how the thing was measured, ethics, and real-world application. One warning I wish we had known sooner — an ethics criticism attacks the researcher, not the finding, so it usually scores nothing on a validity question. Save it for questions that ask about ethics directly.

Reviewing 25 studies without drowning

Blurting beats rereading, and mixing beats blocking.

Blurting: blank page, write everything you have for one study, check it against the card, add the missing lines in another colour. A day or two later, rewrite only what you missed.

Mixing: revise five cards drawn from three different topics in one sitting, not one whole topic at a time. The exam asks for studies out of order, so practise retrieving them out of order.

Twenty-five studies at five a day is a full cycle in five days, repeated weekly — about fifteen minutes daily. If you want the cards built and shuffled for you, drop your notes into flashcards, then use quiz to test findings rather than names.

Mistakes I made first

• I wrote cards as paragraphs. Anything longer than a line does not come back under exam pressure.
• I made her learn names and years before findings. Wrong order — the finding earns the description marks.
• I left evaluation until the end of the topic. Build line four the same day as the rest.
• We recognised instead of recalled for a week. Reading a card and thinking "yes, I know that" is not knowing it. If it did not come out of your pen, it is not learned.

If a study still will not sit still, ask for it in plainer terms on explain, then write a practice answer and run it through grade to see whether your evaluation is developed or just asserted.

Test yourself

1. In Loftus and Palmer, what were the mean speed estimates for the verbs "smashed" and "contacted"?
2. Name the three clauses of a fully developed evaluation point.
3. Why does an ethics criticism usually score poorly on a question about validity?

FAQ

Do I need to memorise the year a study was published?

Rarely. Mark schemes credit the finding and the method, not the date. The exception is Cambridge core studies, which the syllabus names, so getting the surname right helps you pick the correct study under pressure. Learn surnames, skip years.

How many studies do I actually need?

Twenty to twenty-five, spread so every topic has at least two. Two studies you can describe and evaluate beat six you half-remember.

What if I blank on the researcher's name in the exam?

Write the study anyway. "One study found that participants asked about cars that smashed gave higher speed estimates than those asked about cars that contacted" earns description marks on most GCSE mark schemes. Never leave a space empty because a name has gone.

Should I learn the exact statistics?

Learn one number per study, not all of them. One figure gives your answer specificity without becoming another thing to forget. For Milgram, make it 65 percent.

In short: stop rereading studies and start rebuilding them from nothing. Four lines each, one real number in the findings, one evaluation point that finishes its own sentence, reviewed in mixed batches of five. That is the whole difference between recognising a study on the page and writing it under timed conditions.
