Social Psychology - Impression Formation and Person Perception

Social Psychology: Impression Formation and Person Perception

This lecture focuses on how we form impressions of others, covering various theories and experiments in social psychology.

Impressions

Impressions are formed based on available information, such as adjectives describing a person. For example, a description might portray someone's mother as dynamic, creative, and a workaholic, setting high expectations for others.

Halo Effect

The Halo Effect, described by Edward L. Thorndike (1920), is a generalized tendency to form impressions where positive or negative traits influence the perception of other traits. For instance, an attractive person might automatically be perceived as likeable, intelligent, and empathetic.

The Halo Effect impacts impression formation and interpersonal treatment; attractive individuals may be punished less severely for transgressions, and more attractive children may be reprimanded less severely.

Gestalt Psychology and Solomon Asch

Solomon Asch (1907-1996) applied Gestalt psychology principles to impression formation, emphasizing a holistic approach.

Gestalt Principles

Gestalt principles include:

  • Emergence

  • Multistability

  • Subjective contours

  • Law of Similarity

  • Law of Prägnanz (Law of Good Figure)

  • Law of Proximity

  • Law of Continuity

  • Law of Closure

  • Law of Common Region

  • Invariance

  • Closure

  • Similarity

  • Proximity

  • Continuity

  • Common fate

Configurational Perspective vs. Atomistic Perspective

  • Configurational Perspective: Impression formation is a holistic process.

    • Relational Principle: Relations between traits lead to the emergence of an impression.

  • Atomistic Perspective: Impression formation is merely an aggregate of elementary traits.

    • Empiricist Principle: Traits are associated through juxtaposition.

Experiment 1: Asch's Experiment

Participants form an impression of a person (Person A) based on a set of adjectives: intelligent, skillful, hardworking, warm, determined, practical, and cautious.

Findings:

  1. It is easy to form a general impression from a set of adjectives.

  2. The resulting impression is unified, unique, and consistent, even though the adjectives are discrete units.

  3. The impression extends beyond the listed characteristics, creating a complete and unified view, including aspects not directly stated.

  4. Impressions diverge among individuals, with different people assigning varying relevance to different characteristics.

Variation:

A second person (Person B) is described with the same adjectives except “warm” is replaced with “cold.” The change significantly impacts the overall impression of agradability. Person A (with “warm”) is rated higher in agradability (16.75) compared to Person B (with “cold”) (12.2).

Semantic descriptors also differ. Free descriptions of Person A include someone sincere in arguments, while Person B is seen as a rather snobbish, calculating, and unsympathetic individual.

Experiment 2: Central vs. Peripheral Traits

In this experiment, the adjectives
