🤔 4.1 Attribution Theory and Person Perception
🎯 Learning Objectives
- Explain attribution theory and types of attributions
- Identify attribution biases and their effects
- Understand person perception processes
- Describe impression formation and management
- Analyze cultural differences in attribution
🔍 Attribution Theory
- Definition: How we explain the causes of behavior
- Internal Attribution: Behavior due to personality/character
- External Attribution: Behavior due to situation/environment
- Stable Attribution: Cause unlikely to change over time
- Unstable Attribution: Cause likely to change
- Controllable: Person can control the cause
- Uncontrollable: Person cannot control the cause
🎭 Attribution Biases
- Fundamental Attribution Error: Overestimate internal causes for others' behavior
- Actor-Observer Bias: Internal attributions for others, external for self
- Self-Serving Bias: Internal attributions for success, external for failure
- Ultimate Attribution Error: Biased attributions for outgroup members
- Defensive Attribution: Blame victims to feel safer
- False Consensus Effect: Overestimate how much others agree with us
👁️ Person Perception
- First Impressions: Quick judgments based on limited info
- Primacy Effect: First information has greatest impact
- Recency Effect: Recent information has greater impact
- Halo Effect: One positive trait influences overall impression
- Physical Attractiveness: Influences many judgments
- Nonverbal Cues: Body language, facial expressions
🎨 Impression Formation
- Central Traits: Key characteristics that shape overall impression
- Peripheral Traits: Less important characteristics
- Implicit Personality Theory: Assumptions about trait relationships
- Stereotypes: Generalized beliefs about groups
- Confirmation Bias: Seek info confirming impressions
- Self-Fulfilling Prophecy: Expectations influence outcomes
🎪 Impression Management
- Self-Presentation: Control how others perceive us
- Ingratiation: Try to be liked

- Exemplification: Try to appear moral
- Supplication: Try to appear helpless
🌍 Cultural Differences
- Individualistic Cultures: Emphasize internal attributions
- Collectivistic Cultures: Emphasize external attributions
- Western Cultures: More fundamental attribution error
- Eastern Cultures: More situational awareness
- Cultural Values: Influence attribution patterns
- Social Norms: Shape person perception processes
🔑 Key Takeaways
- Attribution theory explains how we make sense of behavior by identifying causes
- Multiple biases systematically distort our attributions and person perception
- First impressions are powerful and difficult to change once formed
- We actively manage impressions to influence how others perceive us
- Cultural background significantly influences attribution patterns and person perception
💭 4.2 Attitude Formation and Attitude Change
🎯 Learning Objectives
- Define attitudes and their components

🧩 Components of Attitudes
- Cognitive Component: Beliefs and thoughts about attitude object
- Affective Component: Emotional feelings toward attitude object
- Behavioral Component: Actions or intentions toward attitude object
- Attitude Object: Person, thing, or idea attitude is about
- Example: Attitude toward exercise (beliefs, feelings, behaviors)
- Consistency: Components usually align but can conflict
🌱 Attitude Formation
- Direct Experience: Personal contact with attitude object
- Observational Learning: Watch others' attitudes and behaviors
- Classical Conditioning: Associate object with positive/negative stimuli
- Operant Conditioning: Rewards/punishments shape attitudes
- Social Learning: Learn from family, peers, media
- Genetic Factors: Some attitudes have biological basis
🔄 Cognitive Dissonance
- Definition: Discomfort from conflicting cognitions
- Festinger's Theory: Motivated to reduce dissonance
- Change Attitude: Modify beliefs to match behavior

📢 Elaboration Likelihood Model
- Central Route: Careful evaluation of message content
- Peripheral Route: Focus on superficial cues
- Motivation: Personal relevance affects route choice
- Ability: Knowledge and cognitive resources matter
- Central = Durable: More lasting attitude change
- Peripheral = Temporary: Less lasting change
🎯 Persuasion Techniques

- Message Quality: Strong arguments and evidence
- Audience Factors: Intelligence, self-esteem, mood
- Fear Appeals: Scare tactics (effective with solutions)
- Social Proof: Others believe/do this too
- Reciprocity: Return favors and concessions
🛡️ Resistance to Persuasion
- Inoculation: Exposure to weak counterarguments builds resistance
- Reactance: Opposition when freedom threatened
- Forewarning: Knowing persuasion attempt increases resistance

🔑 Key Takeaways

- Cognitive dissonance motivates people to reduce inconsistency between attitudes and behaviors
- Persuasion effectiveness depends on source, message, audience, and processing route
- Multiple factors contribute to resistance against attitude change attempts

🎯 Learning Objectives
- Explain conformity and factors that influence it
- Understand obedience to authority and its mechanisms
- Describe group dynamics and social facilitation

🧪 Classic Social Psychology Studies
Asch Conformity
Line length judgments. 76% conformed at least once. Group pressure influences behavior.
Milgram Obedience
Electric shock study. 65% went to maximum voltage. Authority powerfully influences obedience.
Stanford Prison
Zimbardo's role experiment. Situations powerfully shape behavior and identity.
Bystander Effect
Kitty Genovese case. More bystanders = less likely to help. Diffusion of responsibility.
🐑 Conformity
- Definition: Changing behavior to match group norms
- Normative Influence: Conform to be liked/accepted
- Informational Influence: Conform to be correct
- Unanimity: All group members agree increases conformity
- Group Size: 3-5 people optimal for conformity
- Cohesion: Closer groups produce more conformity
- Cultural Differences: Collectivistic cultures conform more
👮 Obedience to Authority
- Definition: Following direct commands from authority figure
- Legitimate Authority: Person perceived as having right to command
- Gradual Escalation: Small requests lead to larger ones
- Proximity: Physical closeness to authority increases obedience
- Institutional Support: Престижious setting increases obedience
- Personal Responsibility: Reduced when following orders
🏃 Social Facilitation & Inhibition
- Social Facilitation: Others' presence improves performance
- Social Inhibition: Others' presence impairs performance
- Zajonc's Rule: Presence enhances dominant response
- Simple Tasks: Presence helps performance
- Complex Tasks: Presence hurts performance
- Evaluation Apprehension: Fear of judgment affects performance
👥 Group Dynamics
- Social Loafing: Reduced effort in group tasks
- Deindividuation: Loss of individual identity in groups
- Groupthink: Desire for harmony overrides critical thinking
- Group Polarization: Groups make more extreme decisions
- Risky Shift: Groups make riskier decisions than individuals
- Social Roles: Expected behaviors in group positions
🤝 Helping Behavior
- Bystander Effect: Less likely to help when others present
- Diffusion of Responsibility: Responsibility spread among bystanders
- Pluralistic Ignorance: Others' inaction suggests no help needed
- Decision Model: Notice → Interpret → Responsibility → Know How → Help
- Altruism: Helping without expectation of reward
- Prosocial Behavior: Any behavior intended to help others
🚫 Prejudice & Discrimination
- Prejudice: Negative attitude toward group members
- Discrimination: Negative behavior toward group members
- Stereotypes: Oversimplified beliefs about group characteristics
- Ingroup Bias: Favor own group over outgroups
- Outgroup Homogeneity: See outgroup members as similar
- Contact Hypothesis: Equal status contact reduces prejudice
🔑 Key Takeaways
- Social situations powerfully influence individual behavior through conformity and obedience
- Group presence can either enhance or impair performance depending on task complexity
- Group dynamics create unique phenomena like groupthink, polarization, and social loafing
- Helping behavior is influenced by social factors, particularly the presence of others
- Prejudice and discrimination persist through psychological and social mechanisms

😊 4.7 Emotion
⚡ Theories of Emotion
James-Lange Theory
Stimulus → Physiological Response → Emotion
