QCE Psychology — Unit 4
Social Influence — Flashcards & Quiz
Social influence studies how the presence and actions of others shape individual behaviour. QCE Psychology Unit 4 The Influence of Others examines classic experiments (Asch on conformity, Milgram on obedience, Zimbardo on roles) and asks you to apply concepts like normative and informational social influence, and to critically evaluate the ethics and methodology of landmark studies.
Key Points
- Conformity: changing behaviour to match a group. Asch's line experiment showed ~33% conformity to clearly wrong answers.
- Normative social influence: conforming to be liked or accepted (fear of social rejection).
- Informational social influence: conforming because you believe others have more accurate information (especially in ambiguous situations).
- Obedience: following instructions from an authority. Milgram's shock experiment showed ~65% of participants delivered supposedly fatal shocks under authority pressure.
- Bystander effect: individuals less likely to help a victim when others are present — diffusion of responsibility (Darley and Latane's studies).
- Ethical issues: Milgram and Zimbardo faced significant criticism for psychological harm and informed consent failures; these shaped modern research ethics.
Common Mistakes to Avoid
- Confusing conformity (peer influence) with obedience (authority influence).
- Treating Asch and Milgram as the same study — they test different phenomena.
- Forgetting ethical critiques when asked to evaluate classic studies.
- Claiming diffusion of responsibility is the only explanation for the bystander effect — evaluation apprehension and pluralistic ignorance also contribute.
- Using outdated figures (e.g. Milgram's study is from the 1960s, modern partial replications confirm the general pattern).
Exam Strategy
QCAA Unit 4 social influence questions ask you to describe studies, apply concepts, or evaluate methodology. Method: (1) define the type of influence (conformity, obedience, bystander), (2) describe the classic study's procedure and findings, (3) explain the mechanism (normative/informational), (4) evaluate ethics and validity.
Revision Tip
Classic studies are recall-heavy — drill a Revizi deck with study name, aim, procedure, key finding, and ethical critique for Asch, Milgram, Zimbardo, Darley and Latane.
