14 Social Perception and Social Cognition

Introduction to Social Psychology

  • Course: PSYC10004/10012 at University of Bristol

  • Instructor: Dr. Justin Park

Human Sociality

  • Humans possess a unique capacity for sociality:

    • Form long-term bonds

    • Remember details about many individuals

    • Learn from others spontaneously

    • Cooperate with strangers

  • Evolutionarily successful due to complex sociality rather than individual capabilities.

Cognitive Performance Comparison

  • Cognitive tests (Henrich, 2016) showed:

    • Humans outperform other primates (chimpanzees, orangutans) in tasks involving social learning.

Kellogg Study on Environmental Influence

  • Study by Kellogg & Kellogg (1933): Chimpanzee raised like a child.

    • Found that the chimp learned to walk upright and had significant word recognition.

    • The boy and chimp showed similar developmental patterns, indicating the influence of a human social environment.

Evolution of Sociality

  • Sociality isn't universal; some species are solitary.

  • Benefits of social living include:

    • Coordinated defense against threats

    • Group hunting and gathering

    • Child rearing

    • Knowledge transfer.

Implications of Human Sociality

  • As humans evolved socially, corresponding psychological and neural mechanisms adapted:

    • Social learning and relationship management

    • Awareness of social risks like disease transmission and exclusion.

The Social Brain Hypothesis

  • Suggests a link between brain size (neocortex) and social complexity:

    • More social information leads to larger brains.

  • Evidence supports this, showing primates' group size correlates with neocortex size.

Imagination and Cooperation

  • Humans' ability to create imagined realities enhances cooperation in large groups.

  • Institutions like churches and universities are examples of this social mechanism.

Social Perception and Cognition

  • Mechanisms for understanding others include:

    • Reading emotional expressions

    • Forming impressions

    • Understanding mental states (theory of mind)

    • Stereotyping based on social categories.

Emotional Expressions

  • Are emotions universal or culturally relative?

  • Earlier views emphasized cultural relativity until the 1990s.

Basic Emotions

  • Paul Ekman's theory:

    • Humans have basic emotions (anger, fear, disgust, surprise, happiness, sadness) associated with significant adaptive behaviors.

    • Evidence shows these are innate and cross-culturally shared.

Limitations of Emotional Research

  • Real-life emotions are more varied than Ekman's discrete expressions.

  • Context and body language play crucial roles in perception of emotions.

Attributions in Behavior Explanation

  • We interpret behaviors using two types of attributions:

    • Dispositional (internal): explanations based on stable traits.

    • Situational (external): explanations based on context.

Accuracy of Attributions

  • Attributions formed spontaneously can impact judgment and behavior.

  • People often overlook situational factors, leading to bias.

Correspondence Bias

  • Tendency to make internal attributions, known as the fundamental attribution error.

  • Cultural variations exist; some cultures attribute more to situational causes.

Cognitive Processing in Attribution

  • Attribution involves:

    1. Automatic dispositional attribution.

    2. Corrective situational attribution may need motivation and resources.

Dispositional Attribution as Default

  • Default attributions may be adaptive, helping predict future behavior based on perceived traits.

Reflection Questions

  • Why do sociability levels vary among individuals?

  • Do emotional states serve specific functions?

  • How do people explain their own actions in contexts like job interviews?

Social Brain Hypothesis

The Social Brain Hypothesis suggests a link between brain size, specifically the neocortex, and social complexity. It posits that the need to process social information in larger groups has led to the evolution of larger brains. Evidence supports this hypothesis, showing that the size of the neocortex in primates correlates with group size, implying a relationship between cognitive capacity and social living.

Paul Ekman's Approach to Emotions

Paul Ekman’s approach to emotions identified basic emotions that are universally recognized, including anger, fear, disgust, surprise, happiness, and sadness. Ekman discovered that these emotions are associated with significant adaptive behaviors and are innate, suggesting they are cross-culturally shared.

Limitations of Ekman’s Research

Despite Ekman's findings on basic emotions, recent studies have revealed that real-life emotions are considerably more nuanced than his discrete expressions. These studies highlight the crucial role of context and body language in the perception of emotions, indicating that understanding emotions may require more than simply identifying universal expressions.

Attribution

Attribution refers to how individuals interpret the causes of behavior. There are two major types of attribution:

  1. Dispositional (internal): Explanations based on stable traits of an individual.

  2. Situational (external): Explanations based on contextual factors affecting behavior.

Correspondence Bias

Correspondence bias, also known as the fundamental attribution error, is the tendency to favor internal dispositional attributions over situational ones when explaining others' behaviors. This bias may exist because individuals tend to focus on behavior without considering situational influences, leading to an oversimplified understanding of social interactions.
