Unit 9: Social Psychology
Social psychology examines how individuals think, feel, and behave in social situations. This unit investigates the powerful forces of social influence, including conformity, obedience, persuasion, and group dynamics, as well as the cognitive processes underlying social perception—attribution, attitudes, and stereotypes. Students will analyze classic experiments by Asch, Milgram, and Zimbardo that revealed the extent to which ordinary people yield to group pressure and authority. The unit also covers the psychology of relationships, aggression, and altruism, asking why people help or harm one another and what factors promote cooperation versus conflict. Understanding social psychology is essential because it illuminates the roots of prejudice, the mechanisms of propaganda, the dynamics of leadership, and the conditions that foster social change. In an era of viral misinformation, political polarization, and global interdependence, social psychological literacy is a prerequisite for responsible citizenship and effective interpersonal communication.
KEY CONCEPTS
- Attribution Theory: The process of explaining the causes of behavior. Fritz Heider distinguished between dispositional (internal) attributions (attributing behavior to personality) and situational (external) attributions (attributing behavior to the environment). The fundamental attribution error is the tendency to overestimate disposition and underestimate situation when explaining others' behavior.
- Attitudes and Behavior: Attitudes are feelings, often influenced by beliefs, that predispose us to respond in a particular way. The attitude-behavior relationship is moderated by external constraints and social pressures. Cognitive dissonance theory (Festinger) proposes that when attitudes and behavior conflict, we often change our attitudes to reduce the discomfort.
- Conformity: Adjusting behavior or thinking to coincide with a group standard. Solomon Asch's line-judgment experiments showed that people conform to avoid rejection (normative social influence) or because they believe the group is correct (informational social influence).
- Obedience: Compliance with commands given by an authority figure. Stanley Milgram's shock experiments revealed that approximately 65% of participants would deliver what they believed to be lethal shocks when ordered by an experimenter, illustrating the power of legitimate authority and gradual commitment.
- Social Facilitation and Social Loafing: Social facilitation is improved performance on simple or well-learned tasks in the presence of others. Social loafing is the tendency for individuals to exert less effort when working in a group than when working alone. Both phenomena demonstrate how the mere presence of others affects motivation.
- Groupthink: A mode of thinking that occurs when the desire for harmony in a decision-making group overrides realistic appraisal of alternatives. Symptoms include illusion of invulnerability, self-censorship, and pressure on dissenters. The Bay of Pigs invasion is a classic example.
- Stereotypes, Prejudice, and Discrimination: A stereotype is a generalized belief about a group. Prejudice is an unjustifiable attitude toward a group. Discrimination is unjustifiable negative behavior toward a group. All three can operate independently, and implicit biases often persist even when explicit attitudes change.
VOCABULARY
- Fundamental Attribution Error (FAE): The tendency for observers, when analyzing others' behavior, to underestimate the impact of the situation and overestimate the impact of personal disposition. We excuse our own behavior situationally but judge others dispositionally.
- Self-Fulfilling Prophecy: A belief that leads to its own fulfillment. For example, if a teacher expects a student to fail, they may treat the student differently, producing the expected failure.
- Cognitive Dissonance: The theory that we act to reduce the discomfort (dissonance) we feel when two of our thoughts (cognitions) or our thoughts and behaviors are inconsistent. We may justify our actions by changing our attitudes.
- Deindividuation: The loss of self-awareness and self-restraint occurring in group situations that foster arousal and anonymity. Mob violence and online trolling are often explained through deindividuation.
- Bystander Effect: The tendency for any given bystander to be less likely to give aid if other bystanders are present. Diffusion of responsibility, pluralistic ignorance, and evaluation apprehension contribute to this effect.
- Reciprocity Norm: An expectation that people will help, not hurt, those who have helped them. This norm underlies much of social exchange and cooperation.
- Social-Responsibility Norm: An expectation that people will help those dependent upon them. This norm motivates altruism toward vulnerable individuals.
- Out-Group Homogeneity Bias: The tendency to view members of out-groups as more similar to one another than members of in-groups. This bias fuels stereotyping and intergroup conflict.
MODELS, THEORIES, AND FRAMEWORKS
- Asch's Conformity Experiments (1951): Participants judged line lengths after confederates gave obviously wrong answers. About 75% conformed at least once; 37% of responses were conforming. The experiments demonstrated the power of normative social influence and the discomfort of dissent.
- Milgram's Obedience Studies (1963): Participants believed they were administering electric shocks to a learner. Despite the learner's protests, 65% continued to the maximum voltage under the experimenter's orders. Variations showed that obedience decreased when the authority was remote, when the victim was nearby, or when peers rebelled.
- Zimbardo's Stanford Prison Experiment (1971): College students randomly assigned to be guards or prisoners rapidly adopted their roles, with guards becoming abusive and prisoners becoming submissive. Though methodologically controversial, the study illustrated the power of social roles and situational forces.
- Sternberg's Triangular Theory of Love: Love consists of three components: intimacy (emotional closeness), passion (physical attraction), and commitment (decision to maintain the relationship). Different combinations yield different types of love (romantic, companionate, consummate).
COMMON MISTAKES ON AP EXAMS
- Confusing conformity and obedience: Conformity involves changing behavior to match group norms (no direct command). Obedience involves complying with a direct order from an authority figure. Asch studied conformity; Milgram studied obedience.
- Stating that Milgram's participants were unusually cruel: Milgram emphasized that his participants were ordinary people placed in extraordinary situations. The lesson is the power of the situation, not the pathology of the individual.
- Confusing stereotype, prejudice, and discrimination: Stereotype = cognitive (belief). Prejudice = affective (attitude). Discrimination = behavioral (action). They often co-occur but can exist independently.
- Attributing bystander inaction solely to apathy: The bystander effect is not explained by indifference alone. Pluralistic ignorance (assuming others are not alarmed), diffusion of responsibility (assuming someone else will help), and evaluation apprehension (fear of embarrassment) are critical mechanisms.
AP EXAM STRATEGIES
- Use the fundamental attribution error to explain social judgments: When analyzing why someone blamed a victim or praised a hero, explain how the FAE leads observers to attribute outcomes to character rather than circumstance.
- Distinguish normative and informational social influence: Normative = conform to be liked/accepted (Asch's public responses). Informational = conform because we believe others have accurate information (crisis situations, ambiguous tasks). This distinction earns analytic points.
- Apply social psychology to current events: Reference social media echo chambers (group polarization), online deindividuation, viral challenges (conformity), and political obedience to authority. Contemporary examples demonstrate relevance.
- Identify the mechanisms of persuasion: The central route (logic, evidence) leads to durable attitude change. The peripheral route (attractiveness, emotion, heuristics) leads to temporary change. High-scoring responses specify which route is operating and why.
REAL-WORLD APPLICATIONS
- Reducing Prejudice Through Contact: Gordon Allport's contact hypothesis states that prejudice declines when groups interact under conditions of equal status, common goals, intergroup cooperation, and institutional support. Integrated schools and cooperative learning programs (e.g., Jigsaw Classroom) apply this principle.
- Social Psychology in Public Health Campaigns: Health interventions use normative feedback (telling college students that most peers drink less than they think) to reduce risky behavior, leveraging social norms rather than scare tactics.
- Leadership and Organizational Culture: Understanding groupthink, social facilitation, and social loafing helps leaders design teams, set individual accountability, and encourage dissent, improving decision-making in businesses, government, and military contexts.
