Measure the extent to which people conformed to the opinion of others, even in a situation where the others' answers were clearly wrong
What was Asch's procedure?
Ps shown 2 cards, had to match line on 1st card to a line on the 2nd card.
Confederates (all but one) said the wrong answer
What were the findings of Asch's research?
Naïve participants conformed 36.8% of the time, shows a high level of conformity when the situation is unambiguous.
75% conformed at least once
What were the 3 variables Asch investigated?
Group size
Unanimity
Task difficulty
How did Asch investigate group size?
Varied the number of confederates between 1 and 15
What were Asch's findings for group size?
Relationship between group size and level of conformity was curvilinear
2 confederates conformity was 13.6%, 3 confederates conformity rose to 31.8%. levelledoff after this
How did Asch investigate unanimity?
Introduced a dissentingconfederate, sometimes gave the correct answer or a different, incorrect answer
What were the findings for unanimity?
Conformity reduced to less than 1/4 of the level it was when there was no dissenter.
Reduced regardless of right or wrong answer
Why did the dissenter reduce conformity?
Allowed the participant to behave more independently
How did Asch study task difficulty?
Made the line-judging task harder by making the lines more similar in length
What were the findings of increasing task difficulty?
Conformity increased
Why did conformity increase when the task increased in difficulty?
The situation was more ambiguous, more likely to look to others for guidance and assume they are right
Example of ISI
Limitations of Asch study?
Artificial task
Little application - only American men tested. Neto (1995) suggested women might be more conformist due to concern of socialrelationships
Collectivist cultures might behave differently
Strength of Asch research:
Other evidence to support
Lucas et al - asked Ps to solve 'easy' and 'hard' mathsproblems. Given answers claimed to be from 3 others. conformed more often when the problems were harder
