The social reciprocity norm is the social expectation that people should help, and return favors to, those who have helped them. In AP Psych (Topic 4.3, LO 4.3.C), it's one explanation for prosocial behavior, where helping is driven by a sense of social debt rather than pure altruism.
The social reciprocity norm is the unwritten social rule that says "you helped me, so I owe you one." When someone does you a favor, you feel a pull (sometimes a strong one) to pay it back. That feeling of owed-ness is what psychologists call social debt.
In the AP Psych CED, this norm shows up under prosocial behavior. Altruism means selfless helping with no expectation of return, but the CED points out that a lot of helping isn't fully selfless. The social reciprocity norm and the social responsibility norm both explain why people help even when they're not being purely altruistic. With reciprocity, the motivation is mutual obligation. You give because you got, or because you expect to get later. It can even run forward in time, like donating items to new players in a game because you expect the same help when you need it.
This term lives in Unit 4: Social Psychology and Personality, specifically Topic 4.3 (Psychology of Social Situations). It directly supports LO 4.3.C, which asks you to explain how prosocial behavior affects behavior and mental processes. The CED names the social reciprocity norm explicitly as one of two norms (alongside the social responsibility norm) that explain helping driven by social debt.
It also connects back to LO 4.3.A, since reciprocity is itself a social norm, one of those society-wide expectations that shape how you behave in social situations. And it quietly powers persuasion. Compliance techniques like door-in-the-face work because the other person feels they owe you a concession. So one small term ties together prosocial behavior, social norms, and persuasion, three threads of the same topic.

Social Responsibility Norm (Unit 4)
These are the CED's matched pair for explaining non-altruistic helping. Reciprocity says "I help you because you helped me (or will)." Responsibility says "I help you because you need it," no payback expected. The exam loves making you pick between them, so know which direction the obligation points.
Door-in-the-Face Technique (Unit 4)
This persuasion tactic runs on reciprocity. When someone drops a huge request down to a smaller one, it feels like they made a concession, so you feel obligated to concede back by saying yes. It's the reciprocity norm weaponized for compliance.
Persuasion (Unit 4)
A small gift before a request (free address labels with a donation envelope, a sample at the store) creates social debt before you've decided anything. That's why people donate more after receiving a tiny freebie. The persuader is cashing in your sense of obligation.
Bystander Effect and Situational Variables (Unit 4)
Both fall under LO 4.3.C's prosocial behavior umbrella, but they answer opposite questions. The reciprocity norm explains why people DO help (felt obligation), while the bystander effect explains why people DON'T (diffusion of responsibility across a crowd). Pair them when explaining what predicts helping.
On the multiple-choice section, this term shows up as a scenario you have to label. The stems follow a pattern. Someone receives help or a small gift, then helps in return, and you identify which norm explains it. Examples in that style include gamers donating items expecting future help back, people donating to charity after a solicitor hands them a small gift, and a student volunteering at a shelter because her family once received community support. The giveaway is the loop. If the helping is a response to past help (or an expectation of future help), it's reciprocity. If the person helps purely because someone is dependent or in need, it's the responsibility norm instead.
No released FRQ has used this term verbatim, but it fits the Article Analysis Question and Evidence-Based Question format well, since prosocial behavior research (why people donate, volunteer, or help strangers) is classic FRQ territory. Be ready to apply the term to a described study, not just define it.
Both norms explain helping, and the CED lists them side by side, which is exactly why they get mixed up. The difference is the reason for helping. The reciprocity norm is transactional, so you help because you were helped (or expect to be), creating a two-way exchange. The social responsibility norm is one-way, so you help people who depend on you or are in need, like children or disaster victims, with no expectation of payback. Quick test for any scenario: ask "is there a favor being returned?" If yes, it's reciprocity. If the person just needs help, it's responsibility.
The social reciprocity norm is the expectation that you should help and return favors to people who have helped you.
It's listed in the CED under LO 4.3.C as one explanation for prosocial behavior driven by social debt rather than pure altruism.
Reciprocity is two-way (favors get returned), while the social responsibility norm is one-way (you help people in need with no payback expected).
Compliance tactics like door-in-the-face and free-gift-before-the-ask work by triggering the reciprocity norm.
On MCQs, look for a helping loop in the scenario, like someone helping because they received help before or expect help later, to identify reciprocity.
It's the social expectation that you should help and return favors to those who have helped you. In the AP Psych CED (Topic 4.3, LO 4.3.C), it explains prosocial behavior motivated by social debt rather than pure selflessness.
No. Altruism is selfless helping with no expectation of return. The CED specifically frames the reciprocity norm as an alternative explanation, where people help because they feel they owe someone or expect future help back.
Reciprocity is an exchange, so you help because you were helped or expect to be helped later. Responsibility is need-based, so you help dependent people (kids, disaster victims) with no payback involved. Ask whether a favor is being returned to tell them apart.
The small gift creates social debt, activating the reciprocity norm, so people feel obligated to give back by donating. This exact scenario (more donations after a solicitor's small gift) is a classic AP Psych multiple-choice setup.
Yes. It's named in the CED's essential knowledge for LO 4.3.C in Unit 4, so it's fair game, most often as a scenario-identification multiple-choice question where you distinguish it from the social responsibility norm or altruism.
