- Asch - majority influence
- Asch's vision test
- Aim - would real ppts conform to majority influence on an unambiguious task
- 123 male american students
- PPT's seated around a table and looked at two cards.
- 1) one vertical line
- 2) three vertical lines of different lengths
- All but one ppts were confederates
- In turn each ppts called out which of the three lines were the same length
- The reall ppts called out last
- The confederates gave wrong answers on 12/18 trials.
- Critical trials
- F= 12 CT 33% made by real ppts were incorrect
- F= 25% of ppts never conformed
- PPT's seated around a table and looked at two cards.
- PEI = ppts changed their public behaviour to avoid disapproval from other group members
