Social Cognition and Attitudes - PSYC1030 Week 5
Impression Formation
Definition: The process of combining information about others to form a judgment.
Algebraic Model: Developed by Anderson (), impressions are formed through mechanical combinations of traits:
Summative: The sum of all trait ratings.
Averaging: The total rating divided by the number of traits.
Weighted Averaging: Attributes are weighted by importance; this model best matches actual human behavior.
Configuration Model: Based on Gestalt principles (Asch, ), stating the whole is greater than the sum of parts.
Central Traits: Highly influential traits that color the meaning of other information.
Peripheral Traits: Less influential traits that take meaning from the context of central traits.
Schemas and Heuristics
Schemas: Cognitive structures representing knowledge about stimuli, based on experience (Alba & Hasher, ).
Event Schemas (Scripts): Expectations for specific situations.
Role Schemas: The parts people play within settings.
Person Schemas: Knowledge about specific individuals or groups (e.g., stereotypes or implicit personality theories).
Heuristics: Mental shortcuts for judgment.
Availability Heuristic: Judging frequency based on the ease of recalling examples (Kahneman & Tversky, ). Media and personal experience often skew these judgments.
Representativeness Heuristic: Judging group membership by comparing a case to a prototype (Tversky & Kahneman, ).
Attribution Theory
Definition: How we infer the cause of behavior as either internal (dispositional) or external (situational) (Heider, ).
Kelley’s Covariation Model (): Attributions are made based on three factors:
Consensus: Do other people behave the same way?
Distinctiveness: Does the behavior occur only toward this target?
Consistency: Does the behavior occur every time in this context?
Attribution Errors:
Fundamental Attribution Error: Overestimating internal factors for others' behavior (Ross, ); more common in individualist cultures.
Actor-Observer Bias: Attributing own actions to external causes and others' to internal ones.
Self-Serving Bias: Attributing success to internal factors and failure to external ones to protect self-esteem.
Attitudes and Persuasion
Attitude Components: Beliefs, Feelings, and Behavioral Tendencies (Himmelfarb & Eagly, ).
Communicator Factors:
Credibility: High-credibility sources (e.g., Oppenheimer) are initially more persuasive than low-credibility ones (e.g., Pravda).
Sleeper Effect: Persistence of a message over time as the source is dissociated from the content (Hovland & Weiss, ).
Attractiveness: Enhances receptiveness to strong arguments.
Message Factors:
Fear: Effective only if combined with high response efficacy and self-efficacy (Rogers, ).
Elaboration Likelihood Model (ELM):
Central Route: High elaboration of arguments; used when motivation and ability are high.
Peripheral Route: Low elaboration; relies on emotional appeals or positive stimuli.
Cognitive Dissonance Theory
Definition: Inconsistency between cognitions creates aversive psychological tension (Festinger, ).
Induced Compliance (Festinger & Carlsmith, ): Participants paid to lie rated a boring task as more enjoyable than those paid . The smaller reward caused higher dissonance, requiring a change in attitude to justify the behavior.
Hypocrisy Effect: Making individuals mindful of past behavior that contradicts their public commitments (e.g., water conservation) leads to behavior change to reduce dissonance (Dickerson et al., ).
