Lecture Notes on Zimbardo's Prison Experiment
Overview of Zimbardo's Prison Experiment
- Purpose: Investigate causes of prison violence
- Location: Basement of Stanford University
- Participants: College-age males randomly assigned as either prison inmates or officers
- Result: Chaos ensued, indicating individuals adapt behavior to fit social roles
Key Concepts
Social Roles
- Definition: Socially defined behavior patterns expected of individuals in certain roles
- Examples:
- Doctor: Empathetic, caring
- Teacher: Knowledgeable, communicative
- Police Officer: Confident, authoritative
- Politician: Persuasive, charismatic
- Student: Curious, hardworking
- Artist: Unconventional, passionate
- Prisoner: Submissive, potentially dangerous
- Correctional Officer: Tough, uncaring
Types of Conformity
- Identification:
- Valuing group membership
- Adopting group behaviors publicly for social identity
Zimbardo's Hypothesis
- Aggression in prisons is situational, not dispositional.
- Prison environment promotes abuse based on expected social roles.
Experiment Details
- Setup: Mock prison; 24 mentally healthy participants selected and randomly assigned
- Prisoners: Experienced arrest, delousing, given uniforms, had rules and rights
- Guards: Given authority symbols; expected to manage without violence
- Zimbardo's Role: Both chief superintendent and lead investigator
Observations
- Participants adopted roles rapidly:
- Prisoners became passive after initial resistance
- Guards showed aggressive behavior, some became sadistic
- Experiment terminated early due to extreme reactions
Evaluation of the Study
Positive Evaluations
- Methodology: High control over variables
- Applications: Insights into real-world institutional abuses (e.g., Abu Ghraib)
Criticisms
- Ethical Concerns: Rare replications due to ethical issues
- Experimenter Bias: Dual roles led to bias; participants influenced by Zimbardo's presence
- Demand Characteristics: Participants possibly acted as expected by researchers
- Direct Instruction: Guards instructed to be aggressive, questioning conclusions
- Harm to Participants: Significant distress experienced by participants
Ethical and Educational Implications
- Importance of ethical safeguards in psychological studies
