#AP Psychology: Social Psychology - The Ultimate Study Guide π
Welcome to the final unit of AP Psychology! This is where everything comes together, focusing on how we interact with and influence each other. Let's make sure you're fully prepared for the exam!
#π― Unit Overview: Social Psychology
This unit is all about how our thoughts, feelings, and behaviors are influenced by the presence of others, whether real or imagined. It's a high-value topic, so let's dive in!
#π‘ Key Concepts:
- Social Influence: How the presence of others affects our actions.
- Social Cognition: How we think about ourselves and others in social situations.
- Social Relations: How we form relationships, help, and hurt others.
#π§ Contextualizing Social Psychology
Remember how we've been focusing on the individual? Now, we're shifting to the social context. Social psychology explores why we behave differently in groups than we do alone. It's like discovering the hidden rules of social interaction. πͺ
#π§ Key Figures and Studies
Many of the foundational studies in social psychology were conducted before strict ethical guidelines were in place. While some of these studies may be unsettling, they are crucial for understanding ethical research practices.
#π¨βπ« Leon Festinger
- Cognitive Dissonance Theory: When our actions and beliefs clash, we feel discomfort. We then try to reduce this discomfort by changing our thoughts or actions.
- Example: You know smoking is bad (belief), but you still smoke (action). To reduce dissonance, you might justify it by saying, "I don't smoke that much" or quit smoking.
Think: Dissonance = Disharmony. We want our thoughts and actions to align.
#π¨βπ« Philip Zimbardo
-
#Stanford Prison Experiment: Demonstrated how quickly people adopt assigned roles, even to the point of engaging in harmful behavior.
This study highlights the power of situational factors over individual personality in determining behavior.
Don't confuse Zimbardo's study with Milgram's. Zimbardo focused on role-playing, while Milgram focused on obedience.
#π¨βπ« Solomon Asch
-
#Conformity Study: Showed that people are likely to conform to group norms, even when they know the group is wrong.
Over one-third of participants conformed to the wrong answer in Asch's study.
Think: Asch = Agreeing. People tend to agree with the group.

*Image: Asch's line comparison task. Participants were asked to match the target line with one of the comparison lines. Confederates purposely gave the wrong answer to test conformity.*
#π¨βπ« Stanley Milgram
-
#Obedience Study: Revealed that people are surprisingly likely to obey authority figures, even when it means harming others.
This study raised significant ethical concerns about the treatment of participants.
Be prepared to discuss the ethical implications of Milgram's experiment on the FRQ.
#ποΈ Key Vocabulary

Free Response Question:
A high school principal is concerned about the level of bullying occurring at their school.
(a) Define the following terms and explain how each might relate to the bullying problem: - Deindividuation - Bystander effect - In-group/out-group bias
(b) Describe one strategy the principal could use to reduce bullying at the school, based on social psychology principles.
Scoring Breakdown:
(a) Definitions and Explanations (3 points)
- Deindividuation (1 point):
- Definition: Loss of self-awareness and restraint in a group setting.
- Explanation: When students are in a group, they may feel less personally accountable for their actions and engage in bullying behavior they wouldn't do alone.
- Bystander Effect (1 point):
- Definition: The tendency for individuals to be less likely to help someone in need when others are present.
- Explanation: Students who witness bullying may not intervene because they assume someone else will, thus perpetuating the problem.
- In-group/Out-group Bias (1 point):
- Definition: The tendency to favor one's own group and view other groups negatively.
- Explanation: Students may target those they perceive as different or not part of their group, leading to bullying.
(b) Strategy (1 point)
- Strategy: The principal could implement a program that creates superordinate goals for students, such as collaborative projects that require students from different groups to work together. This can help reduce in-group/out-group bias and foster a sense of shared identity.
- Explanation: The strategy should be based on a social psych principle and be explained.
