Norms are the shared, often unwritten rules a group uses to define acceptable behavior; in AP Psychology they explain prosocial behavior through the reciprocity and social responsibility norms (Topic 9.6) and drive conformity, since people follow norms to gain acceptance or avoid disapproval.
Norms are the rules of the social game. Every group you belong to, from your family to your country, has expectations about what's okay and what's not, and most of them were never written down anywhere. You learned them by watching what other people do and noticing what gets approval or side-eye.
In AP Psychology, norms show up most directly in Topic 9.6 (Altruism and Aggression), where they help answer a big question: why do people help strangers? The reciprocity norm says we help people who have helped us (you feel weirdly obligated to return a favor). The social responsibility norm says we should help people who depend on us, like children or someone injured, even with no payback coming. Norms also explain the flip side. Cross-cultural research on aggression shows that what counts as an acceptable response to an insult varies by culture, which means aggression isn't purely biological. It's partly a learned, norm-governed behavior.
This term anchors Topic 9.6 (Altruism and Aggression), where the reciprocity norm is one of the main explanations for prosocial behavior, sitting alongside social exchange theory as an answer to "why do we help?" But norms are really the connective tissue of the entire social psychology unit. Conformity is just norm-following in action, the bystander effect happens when the situational norm seems to be "do nothing," and socialization is the process of absorbing norms in the first place. If an exam question involves people changing their behavior because of what a group expects, a norm is almost always the mechanism underneath. That makes it one of the highest-leverage vocabulary words in the unit, because naming the specific norm (reciprocity vs. social responsibility) is exactly the precision AP scorers look for.
Reciprocity Norm (Unit 9)
This is the most testable specific norm. It explains altruism toward non-relatives as a kind of social IOU system. You help others expecting that help flows back eventually. AP questions love pitting it against social exchange theory, which is about weighing personal costs and benefits rather than following a shared rule.
Conformity (Unit 9)
Norms are the rule; conformity is the act of following it. Asch's line studies showed people will give an obviously wrong answer just to match the group, which is normative social influence in its purest form. No norm, no conformity.
Bystander Effect (Unit 9)
In an ambiguous emergency, everyone looks around to figure out the norm, sees nobody else reacting, and concludes the norm is to do nothing. The bystander effect is partly a norm-reading failure, working alongside diffusion of responsibility.
Socialization (Unit 9)
Socialization is how norms get into your head in the first place. Parents, peers, and culture teach you the expectations long before you can name them, which is why norms feel like common sense rather than rules you memorized.
Multiple-choice questions usually test norms through scenarios. A vignette describes someone helping a person who once helped them, and you have to identify the reciprocity norm, or distinguish it from social exchange theory (cost-benefit calculation) and reciprocal altruism (the evolutionary version). Practice questions also use norms in cross-cultural framing, like asking how anthropological research on aggression across cultures changes our understanding of it (answer: it shows aggression is shaped by cultural norms, not just biology). On the free-response side, norms are useful supporting vocabulary for any social influence argument. The 2025 EBQ asked whether the presence of others improves performance, and norm-based reasoning (people adjust behavior to meet group expectations) is exactly the kind of mechanism that strengthens an evidence-based argument. The move you must make on any of these: don't just say "norms," name which norm and tie it to the behavior in the prompt.
A norm is the expectation; conformity is the behavior. Norms are the standing rules of a group ("face forward in an elevator"), while conformity is what happens when an individual adjusts their behavior or beliefs to match those rules. On the exam, if the question asks about the rule or expectation itself, the answer is norms. If it asks about a person changing to fit the group, that's conformity.
Norms are a group's shared, often unwritten expectations for acceptable behavior, learned through socialization rather than formal instruction.
In Topic 9.6, the reciprocity norm (help those who helped you) and the social responsibility norm (help those who depend on you) are norm-based explanations for altruism.
The reciprocity norm is a social rule about obligation, while social exchange theory is an individual cost-benefit calculation; the exam expects you to tell them apart.
Cross-cultural research on aggression shows that norms, not just biology, shape when and how people act aggressively.
Norms are the mechanism behind conformity and the bystander effect, so they connect Topic 9.6 to the rest of the social psychology unit.
Norms are a group's shared rules and expectations for acceptable behavior. In AP Psych they matter most in Topic 9.6, where the reciprocity norm and social responsibility norm explain why people engage in altruism and prosocial behavior.
A norm is the expectation itself, while conformity is the act of changing your behavior to match it. Think of the norm as the rulebook and conformity as actually playing by it.
No. The reciprocity norm is a social rule that says you should return help you've received, regardless of personal payoff. Social exchange theory says you help only when the benefits to you outweigh the costs. One is about obligation, the other is about calculation.
No, most norms are unwritten. Laws are formal norms, but the majority (like not cutting in line or returning a favor) are informal expectations you absorbed through socialization, and breaking them earns social disapproval rather than punishment.
Two norms do the work. The reciprocity norm explains helping people who have helped you, and the social responsibility norm explains helping people who can't repay you, like children or accident victims. Naming the correct one in a scenario question is the skill being tested.
