Perceiving Others Notes

Learning Objectives

  • Differentiate between internal and external attributions.

  • Explain two common perceptual errors: the fundamental attribution error and the self-serving bias.

  • Discuss how the primacy and recency effects relate to first and last impressions.

  • Discuss how physical and environmental factors influence perception.

  • Explain the horn and halo effects.

  • Recognize the roles that culture and personality play in the perception of others.

Attribution and Interpretation

  • Attribution: The process we use to explain behaviors of others.

    • Internal Attributions: Cause of behavior is connected to personal aspects (e.g., personality traits).

    • External Attributions: Cause of behavior is connected to situational factors.

  • Example: If Jerry raises his voice:

    • Internal Attribution by Gloria: "Jerry is a loose cannon."

    • External Attribution by Gloria: "He must be under pressure from work."

  • Cognitive Process: Attributions can be both conscious and automatic.

  • Common Errors:

    • Fundamental Attribution Error: Tendency to overestimate internal causes and underestimate external causes of others’ behaviors.

    • Self-Serving Bias: Tendency to attribute successes to internal factors and failures to external factors for oneself.

Impressions and Interpretation

  • First Impressions: Crucial for future interactions; they are often enduring due to the primacy effect.

  • Last Impressions: The recency effect suggests that the last impression we receive greatly influences our perception.

  • Study indicates people are generally good at making accurate first impressions about others' behaviors and personality traits.

  • Example of Primacy Effect: Sitting at a restaurant without acknowledgment can create a lasting negative impression.

  • Example of Recency Effect: A professor’s late grading could overshadow positive experiences throughout the semester.

Physical and Environmental Influences on Perception

  • Physical appearance and grooming significantly impact first impressions.

  • The Halo Effect: Positive first impressions lead to positive perceptions of subsequent behaviors.

  • The Horn Effect: Negative first impressions lead to negative perceptions of subsequent behaviors.

  • Example of Physical Influence: The style of dress in different professions forms schematic expectations (e.g., doctors vs. artists).

Cultural Influences on Perception

  • Cultural identities (race, gender, etc.) shape our perceptions.

  • Different cultures have varying interpretations of sensory experiences (sight, sound, etc.).

  • Assumed Similarity: The tendency to believe individuals are similar to us based on our traits and experiences.

Personality Influences on Perception

  • Individual personality traits affect perception of self and others.

  • The Big Five Personality Traits include:

    • Extraversion: Sociability vs. introversion.

    • Agreeableness: Trustworthiness vs. suspicion.

    • Conscientiousness: dSelf-organization and motivation.

    • Neuroticism: Emotional stability vs. insecurity.

    • Openness: Willingness to consider new ideas.

  • Personality affects how we interpret behaviors and traits of others, influencing our interactions and assumptions.

Key Takeaways

  • Internal vs. External Attributions: Understanding motives helps predict interactions and reactions.

  • Fundamental Attribution Error: Overemphasis on internal factors when judging others.

  • Self-Serving Bias: Positive outcomes attributed to self; negative outcomes to external sources.

  • Primacy and Recency Effects: Early and late impressions have significant influence on perception.

  • Physical characteristics and environment shape impressions and subsequent interactions.

  • Culture and personality traits heavily influence our perceptions and judgments of others.


  • Differentiate between internal and external attributions in a variety of social contexts.

  • Explain the two common perceptual errors: the fundamental attribution error and the self-serving bias, with real-life examples to illustrate each concept.

  • Discuss how the primacy and recency effects relate to first and last impressions, emphasizing their significance in social interactions and decision-making.

  • Analyze how physical and environmental factors, such as lighting and personal appearance, influence perception and the formation of impressions in different social settings.

  • Explain the horn and halo effects in detail, providing examples of how these biases manifest in everyday situations and their implications for judgment.

  • Recognize the roles that culture and personality play in the perception of others, by exploring cultural differences in social behavior and the impact of personality traits on interpretation and interaction.
