Unit 4.1: Attribution Theory and Person Perception
AP Psychology | Unit 4: Social Psychology and Personality
🎯 Exam Focus
Attribution theory explains how we interpret the causes of behavior. Master dispositional (internal/personality) vs. situational (external/circumstances) attributions, understand explanatory styles (optimistic vs. pessimistic), know locus of control (internal vs. external), and memorize all attribution biases: fundamental attribution error (overestimate personality for others), self-serving bias (credit yourself for success, blame situation for failure), actor-observer bias (situation for self, disposition for others), just-world hypothesis (good things happen to good people). Understand person perception: mere exposure effect, halo effect, self-fulfilling prophecy, social comparison (upward vs. downward), confirmation bias, and false consensus effect. This foundational social psychology topic appears frequently on both multiple-choice and FRQ sections.
📚 Introduction to Social Psychology
Social psychology is the scientific study of how thoughts, feelings, and behaviors are influenced by the actual, imagined, or implied presence of others. It examines how we think about, influence, and relate to one another.
Two fundamental questions drive social psychology: (1) How do we understand and explain other people's behavior? (2) How do we form impressions and perceptions of others? These questions form the foundation of attribution theory and person perception.
As social beings, we constantly seek to make sense of the world around us. We create explanations for why people act the way they do, form first impressions, and develop expectations about others. Understanding these cognitive processes helps us navigate social interactions more effectively.
🔍 Attribution Theory
What is Attribution Theory?
Attribution theory explains how people interpret and explain the causes of behavior — both their own and others'. We create attributions (explanations) to make sense of why people act the way they do.
Core Principle:
When explaining behavior, we attribute causes to either internal factors (personality, character, abilities) or external factors (situation, environment, circumstances). The type of attribution we make profoundly affects our judgments, emotions, and future interactions.
Two Types of Attributions
Dispositional Attribution
Internal/personality-based explanation
Attributes behavior to:
- Personality traits
- Character
- Abilities
- Attitudes
- Motives
Examples: "She failed the test because she's lazy." "He helped because he's kind." "They succeeded because they're smart."
Situational Attribution
External/circumstance-based explanation
Attributes behavior to:
- Environment
- Circumstances
- Luck
- Task difficulty
- Other people's influence
Examples: "She failed because the test was unfair." "He helped because he was asked." "They succeeded because of luck."
💭 Explanatory Style
What is Explanatory Style?
Explanatory style is a person's habitual way of explaining good and bad events in their life. It's a consistent pattern of attributions that reflects how optimistic or pessimistic someone tends to be.
Three Dimensions:
- Internal vs. External: Do I attribute events to myself or outside forces?
- Stable vs. Unstable: Are causes permanent or temporary?
- Global vs. Specific: Do causes affect all areas of life or just one domain?
Optimistic Explanatory Style
For Bad Events:
- External (not my fault)
- Unstable (temporary)
- Specific (affects only this area)
For Good Events:
- Internal (my doing)
- Stable (lasting)
- Global (affects many areas)
Example: "I failed this test because it was unusually hard, but I'll do better next time." "I succeeded because I'm capable and work hard."
Pessimistic Explanatory Style
For Bad Events:
- Internal (my fault)
- Stable (permanent)
- Global (affects everything)
For Good Events:
- External (luck)
- Unstable (won't last)
- Specific (fluke)
Example: "I failed because I'm stupid and I always fail at everything." "I succeeded because I got lucky this time."
🎯 Locus of Control
What is Locus of Control?
Locus of control is the degree to which people believe they have control over the events in their lives. It's about whether you see yourself or external forces as the primary driver of outcomes.
Internal Locus of Control
Belief that you control your outcomes through your own effort, decisions, and actions
Characteristics:
- Take responsibility for successes and failures
- Believe effort matters
- More motivated to achieve
- Better stress management
Example: "My grade depends on how hard I study."
External Locus of Control
Belief that external forces (luck, fate, others) control outcomes
Characteristics:
- Attribute outcomes to luck or chance
- Feel less personal control
- May experience learned helplessness
- More vulnerable to stress
Example: "My grade depends on whether the teacher likes me and how lucky I am."
⚠️ Attribution Biases
Fundamental Attribution Error (FAE)
The fundamental attribution error is our tendency to overestimate the influence of personality and underestimate the influence of the situation when explaining others' behavior.
How It Works:
- We assume others' actions reflect their personality, not their circumstances
- We jump to dispositional attributions for others
- We ignore powerful situational factors affecting their behavior
- We do this especially with people we don't know well
Examples:
- Someone cuts you off in traffic → You think "What a jerk!" (dispositional) rather than "Maybe they're rushing to hospital" (situational)
- Classmate yells at you → You think "They're mean" (dispositional) rather than "They might be having a terrible day" (situational)
- Server is rude → You think "They're a rude person" rather than considering they might have just gotten bad news
Self-Serving Bias
Self-serving bias is the tendency to attribute our successes to internal factors (our abilities, effort) and our failures to external factors (situation, bad luck).
Pattern:
- Success: "I did well because I'm smart/worked hard" (internal/dispositional)
- Failure: "I did poorly because the test was unfair/I had bad luck" (external/situational)
- Protects our self-esteem
- Helps maintain positive self-image
Examples:
- Ace a test → "I'm intelligent and studied well" vs. Fail a test → "The teacher made it too hard"
- Win a game → "I'm skilled" vs. Lose a game → "The referee was unfair"
- Get promoted → "I earned it through hard work" vs. Passed over → "Office politics"
Actor-Observer Bias
Actor-observer bias is the tendency to attribute our own behavior to situational factors but others' behavior to dispositional factors.
The Pattern:
- When I do something: "The situation made me do it" (external)
- When others do the same thing: "They're that kind of person" (internal)
- Related to self-serving bias but broader
- We have more information about our own circumstances
Example:
You're late to class → "There was terrible traffic and I couldn't find parking" (situational). Your friend is late → "They're so irresponsible and never on time" (dispositional).
Just-World Hypothesis
The just-world hypothesis (or just-world phenomenon) is the belief that the world is fair and people get what they deserve — good things happen to good people, bad things happen to bad people.
Consequences:
- Leads to victim-blaming ("They must have done something to deserve it")
- Ignores systemic issues like poverty, racism, or random chance
- Provides false sense of security ("Bad things won't happen to me because I'm good")
- Can reduce empathy for those suffering misfortune
Examples:
- "They're poor because they're lazy" (ignoring systemic poverty)
- "They got sick because of their lifestyle" (ignoring genetic factors or bad luck)
- "Crime victims must have been in the wrong place" (victim-blaming)
👁️ Person Perception
Mere Exposure Effect
The mere exposure effect is the phenomenon where repeated exposure to something makes us like it more, even without conscious awareness.
How It Works:
- Familiarity breeds liking (not contempt!)
- Works for people, objects, music, etc.
- Happens even below conscious awareness
- Explains why we prefer familiar songs, brands, faces
Examples:
You initially dislike a new song, but after hearing it on the radio repeatedly, you start to like it. People who sit near you in class become more likable over time. Advertisers repeat brand names to increase positive feelings.
Halo Effect
The halo effect occurs when one positive characteristic of a person influences our overall impression, causing us to assume they have other positive qualities.
How It Works:
- One positive trait creates "halo" of positivity
- We generalize from one quality to overall impression
- Most common with physical attractiveness
- Opposite: horn effect (one negative trait taints everything)
Examples:
- Attractive people are assumed to be more intelligent, kind, and successful
- Well-dressed person assumed to be more competent
- Successful businessperson assumed to be good at everything
Self-Fulfilling Prophecy
A self-fulfilling prophecy occurs when our expectations about a person or situation influence our behavior in ways that cause those expectations to come true.
The Process:
- Form expectation about person/situation
- Behave in ways consistent with that expectation
- Your behavior influences the other person's behavior
- Other person responds in way that confirms expectation
- Expectation becomes reality
Examples:
- Pygmalion Effect: Teachers who expect students to succeed give them more attention and encouragement, leading to actual success
- You expect someone to dislike you → act cold/defensive → they respond negatively → confirms your expectation
- Expect to fail a test → don't study → actually fail
Social Comparison
Social comparison is the process of evaluating ourselves by comparing ourselves to others. We use others as benchmarks to assess our own abilities, opinions, and worth.
Two Types:
1. Upward Social Comparison
Comparing yourself to someone better than you. Can be motivating (inspiration) or demoralizing (feel inadequate).
2. Downward Social Comparison
Comparing yourself to someone worse off than you. Boosts self-esteem but can lead to complacency.
Examples:
- Upward: Comparing your grades to the class valedictorian (may motivate or discourage)
- Downward: "At least I did better than them" (protects self-esteem)
Additional Person Perception Concepts
Confirmation Bias
The tendency to search for, interpret, and recall information that confirms our preexisting beliefs while ignoring contradictory evidence. We see what we expect to see.
False Consensus Effect
The tendency to overestimate how much others share our beliefs, values, and behaviors. We assume everyone thinks like we do.

Free Response Question (FRQ) Tips
- Identify attribution type: Clearly state whether dispositional or situational and explain why
- Apply biases to scenarios: Explain HOW fundamental attribution error or self-serving bias applies to specific situation
- Explain the mechanism: Don't just name the concept — show how it works in the scenario
- Use precise terminology: "Fundamental attribution error" not "judging people wrong"
- Provide complete explanations: For self-fulfilling prophecy, show all steps from expectation to reality
- Connect concepts: Link attribution biases to person perception when appropriate
- Give specific examples: Use concrete situations to illustrate abstract concepts
✨ Quick Review Summary
🔑 The Big Picture
Attribution theory explains how we interpret behavior. Dispositional attribution blames internal/personality factors; situational attribution blames external/circumstances. Explanatory style is habitual pattern: optimistic (bad events external/temporary/specific, good events internal/stable/global) vs. pessimistic (reverse). Locus of control: internal (you control outcomes) vs. external (outside forces control). Attribution biases: Fundamental attribution error (overestimate personality for others' behavior), self-serving bias (credit yourself for success, blame situation for failure), actor-observer bias (situation for own behavior, disposition for others'), just-world hypothesis (people get what they deserve, leads to victim-blaming). Person perception: Mere exposure effect (familiarity increases liking), halo effect (one positive trait creates overall positive impression), self-fulfilling prophecy (expectations influence behavior to confirm expectations), social comparison upward (compare to better) and downward (compare to worse), confirmation bias (see what confirms beliefs), false consensus effect (overestimate how many share your views).
