Social psychology studies how people think, feel, and behave in the presence of others. This topic helps students understand why individuals may conform, obey authority, help others, stereotype groups, or change opinions in social settings. A cheat sheet is useful because many terms sound similar but describe different causes of behavior. It also connects classic experiments to real-world group behavior in schools, workplaces, media, and politics. The core ideas include social influence, attribution, attitudes, prejudice, aggression, helping behavior, and group decision making. Important models explain how people interpret behavior, respond to pressure, and shift attitudes through persuasion or cognitive dissonance. Group concepts such as group polarization, social loafing, deindividuation, and groupthink show how behavior can change when people act with others. Strong answers in psychology should name the concept, describe the evidence, and apply it accurately to a situation.
Key Facts
- Conformity is changing behavior or beliefs to match a group, often because of normative social influence or informational social influence.
- Normative social influence means a person conforms to gain approval or avoid rejection, while informational social influence means a person conforms because the group seems correct.
- Obedience is following a direct command from an authority figure, and it increases when the authority seems legitimate, close, and responsible for the outcome.
- The fundamental attribution error is overestimating personality causes and underestimating situational causes when explaining another person's behavior.
- Cognitive dissonance theory states that attitude change is likely when a person feels tension because behavior and beliefs conflict.
- Group polarization is the tendency for group discussion to strengthen the average initial opinion of group members.
- Social loafing occurs when individuals put in less effort on a group task because personal responsibility is reduced.
- Groupthink is poor decision making caused by pressure for harmony, often shown by self-censorship, illusion of unanimity, and ignoring warnings.
Vocabulary
- Conformity
- Conformity is changing one's behavior or beliefs to fit the behavior or beliefs of a group.
- Obedience
- Obedience is complying with a direct order from an authority figure.
- Attribution
- Attribution is the process of explaining the cause of a person's behavior as internal, external, stable, or changeable.
- Prejudice
- Prejudice is an unjustified negative attitude toward a person based on membership in a group.
- Group Polarization
- Group polarization is the strengthening of a group's initial attitude after discussion among like-minded members.
- Groupthink
- Groupthink is a decision-making pattern in which the desire for agreement prevents realistic evaluation of alternatives.
Common Mistakes to Avoid
- Confusing conformity with obedience, which is wrong because conformity involves pressure from a group while obedience involves a direct command from an authority.
- Calling every group decision groupthink, which is wrong because groupthink specifically requires pressure for agreement that reduces critical thinking.
- Ignoring the situation when explaining behavior, which is wrong because the fundamental attribution error happens when people overfocus on personality and underweight context.
- Assuming prejudice and discrimination mean the same thing, which is wrong because prejudice is an attitude while discrimination is an action.
- Treating correlation in social psychology studies as proof of causation, which is wrong because two related variables may be influenced by a third factor.
Practice Questions
- 1 In a class of 30 students, 18 students publicly agree with an incorrect answer after hearing most classmates give that answer. What percentage of the class conformed?
- 2 A group project has 5 students, and the final work shows only 3 students contributed equally while 2 contributed very little. What social psychology concept best explains the reduced effort by some members?
- 3 In a survey of 200 people, 120 report that they would follow instructions from a uniformed authority figure even if they felt uncomfortable. What fraction and percentage reported likely obedience?
- 4 A student says, 'The driver cut me off because they are a rude person,' but later learns the driver was rushing to the hospital. Explain which attribution error may have occurred and why the new information matters.
