How to Read Psychology Passages in CAT RC

Psychology passages are popular with exam setters because the subject is familiar enough to read and slippery enough to test. A famous experiment is described, a conclusion is drawn, and then the passage often complicates that conclusion. Aspirants who remember the experiment but miss the complication lose the marks.

This post gives a working method for the genre. It complements our general guide to finding the main idea and to identifying author's tone.

Separate three layers: the finding, the claim, the doubt

Almost every psychology passage has three layers. Keep them apart as you read.

1. The finding is what happened in the study. Participants did X, and the result was Y.
2. The claim is what people took the finding to mean. This is usually the popular version of the story.
3. The doubt is what the author, or later researchers, say about the claim. This layer is where most questions live.

The author's own position is usually in the third layer. A passage on a famous prison simulation, for example, may spend its first half on the finding and its second half on whether the behaviour was spontaneous or directed. If you remember only the finding, you will pick the option that sounds like the textbook.

Read the scope words

Psychology authors hedge, and the hedges are tested. Words such as may, suggests, in some conditions, among these participants and has been argued mark the limits of a claim. A wrong option often removes the hedge and turns a tentative result into a law of human nature.

• If the passage says the effect appeared in one group, an option that generalises to everyone is wrong.
• If the passage says a result failed to replicate, an option that treats the original result as settled is wrong.
• If the passage says a trait is correlated with an outcome, an option that says it causes the outcome is wrong.

Distinguish the phenomenon from the explanation

Psychology passages often describe a phenomenon first and then offer rival explanations for it. A horse appeared to count, and the explanation is that it was reading unconscious cues from its questioner. A child appeared to resist a sweet, and the explanation is about trust in the adult, not willpower. Questions ask which explanation the author prefers, or which new fact would favour one explanation over another. Write the rivals on your rough sheet in two words each.

A short worked example

Read this practice passage.

For decades the test was taken to measure a trait called self control. Later work found that children who trusted the adult in the room waited longer than children who did not. If waiting depends on trust, the trait explanation is incomplete, though it need not be wrong. Both factors may operate, and the experiment, as originally run, could not tell them apart.

A likely question asks which statement the author would accept. The tempting wrong option says the trait explanation is false. The author says it is incomplete and need not be wrong. The correct option keeps both factors open and notes that the original design could not separate them. Notice how every clause of the passage works to limit a claim. That is the signature of the genre.

Terms that keep showing up

• Correlation means two things move together. It does not tell you which causes which, or whether a third thing causes both.
• Replication means repeating a study to see if the result holds. A failed replication weakens a claim without always disproving it.
• Bias and heuristic describe mental shortcuts. Passages often argue that the shortcut is useful in some settings and harmful in others.
• Confound means a hidden factor that muddies a result. Weaken questions often work by introducing one.
• Sample refers to the people studied. If the sample is small or unusual, the passage will usually say so, and an option that generalises beyond it is a trap.

Common mistakes

• Treating a vivid story as the main idea. Passages often use a story to carry an argument that lies elsewhere.
• Reading the author as an expert in the field rather than as a commentator weighing evidence.
• Ignoring the verb. Whether a study showed, suggested, hinted or failed to find makes a large difference.
• Letting prior belief decide. If you believe a famous effect is real, you may reject an option that says it is overstated, even though the passage supports that option.

A weekly routine

Read one psychology essay on three days of the week. After each, write a single line for the finding, the claim and the doubt. After a month you will have a dozen lines, and you will notice that the doubt tends to arrive in the second half of the passage. That habit alone speeds up reading, because you know where to look for the author's real position.

Practise on real essays

• The Psychology of Being Confidently Wrong on a famous effect and how it is often misread.
• The Stanford Prison Experiment Was Directed on a classic study and the doubts about it.
• The Marshmallow That Was Never Only About Willpower on a result and its rival explanation.
• The Horse That Could Count and the Face That Did Not Know on how cues mislead observers.
• The Thirty Eight Witnesses Who Were Not There on a story that outlived its facts.
