Social Influence Concepts

Jun 26, 2025

Overview

This lecture summarizes key concepts in social influence for A Level Psychology, focusing on conformity, obedience, resistance, minority influence, and social change, with supporting studies and definitions.

Conformity

  • Conformity is changing behavior or opinions due to group pressure (Asch, 1951/1958).
  • Compliance: Shallow, public agreement but private disagreement; often due to Normative Social Influence (NSI).
  • Identification: Moderate, temporary change to fit in with a valued group.
  • Internalization: Deep, permanent change in beliefs due to Informational Social Influence (ISI).
  • NSI is driven by the desire to be liked; ISI arises from a need to be correct.
  • Asch’s line study found 32% conformity rate; unanimity and task difficulty increase conformity.

Evaluation of Conformity Studies

  • High internal validity but low ecological validity due to artificial tasks and settings.
  • Replications show cultural differences in conformity rates.
  • Social support and the presence of dissenters reduce conformity rates significantly.

Social Roles and Zimbardo's Prison Study

  • Stanford Prison Experiment showed rapid adoption of assigned roles (guard/prisoner).
  • Situational power of social roles can lead to abusive behavior.
  • Ethical concerns: psychological harm and researcher bias due to Zimbardo’s dual role.
  • Replications challenge the inevitability of conforming to social roles.

Obedience and Milgram’s Experiments

  • Obedience: Following orders from an authority figure.
  • Agentic state: Acting as an ‘agent’ for authority, losing personal responsibility.
  • Legitimacy of authority: Learned acceptance of social hierarchies and symbols of power.
  • Milgram’s shock experiment showed 65% obeyed to maximum voltage.
  • Obedience drops with increased proximity, lower legitimacy of location, and absence of uniform.

Evaluation of Obedience Studies

  • High control and replicability but issues with ecological validity and ethical concerns.
  • Alternative explanations: individual personality differences (authoritarian personality).
  • Field studies like Hofling (nurses) and Bickman (uniforms) support real-world obedience findings.

Resistance to Social Influence

  • Social support from others resisting reduces pressure to conform or obey.
  • Dispositional factors: Locus of control (internal = more resistant, external = less resistant).
  • Studies show internals resist obedience more than externals.

Minority Influence and Social Change

  • Consistency, commitment, and flexibility increase minority influence on majority.
  • The snowball effect describes gradual conversion of the majority to the minority’s viewpoint.
  • Social change occurs when minority views become widely accepted; e.g., civil rights movements.
  • Social cryptoamnesia: society forgets the role of minority groups in social change.

Key Terms & Definitions

  • Conformity — Changing behavior or beliefs due to group pressure.
  • Normative Social Influence (NSI) — Conforming to be liked or accepted by others.
  • Informational Social Influence (ISI) — Conforming due to desire to be correct.
  • Compliance — Outward conformity without private agreement.
  • Identification — Adopting behaviors to fit with a group.
  • Internalization — Genuine acceptance of group norms.
  • Agentic State — Acting on behalf of authority, shifting responsibility.
  • Legitimacy of Authority — Acceptance of social hierarchy and symbols of power.
  • Locus of Control — Degree to which people believe they control outcomes (internal vs. external).
