  • AIM
    • ASCH (1951) STUDY IN NORMATIVE INFLUENCE
      • METHOD
        • - the 50 male American participants were lied to as they were told they were doing an experiment on visual  perception       - they were placed with 7 confiderates that had already rehearsed what they were going to say                   - they were shown a series of cards & asked to match up the line to a clone of 3 comparison line each time
      • FINDINGS
        • - Over all the critical trials, 32% were incorrect          - there were a considerable individual diff in how ppl responded: 25% of participants did not conform at all & 75% did        - Asch noted that the participant that got the most incorrect answers (11/12) appeared nervouse & somewhat confused
      • EVALUATION
        • POSTIVE
          • - this study was a powerful demonstration of how a group can influence behaviour        - well controlled experiment (eliminate extraneous variables thus high reliability & high interna viability)
        • NEGATIVE
          • - lacked ecological validity, as it was in an artificial lab      - not ethical, due to the participants being deceived for what hey signed up for   - findings cannot be generalised to social behaviour due to lack of diversity of participants
          • - small sample size                  - only males were used
    • to see whether ppl would conform to others' incorrect esimates if the task was easy to do
