- 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
- POSTIVE
- METHOD
- to see whether ppl would conform to others' incorrect esimates if the task was easy to do
