Had to compare the line on the left with the lines on
the right and state which ones matched (A, B, C, or D)
123 Participants
All but one of the participants were "confederates"
Instructed the confederates to give the same
incorrect answer on 12 of the 18 trials
"Critical Trials"
The true participant was always the
last or penultimate one to answer
Found a mean conformity rate of 37%
I.e - Participants agreed with the incorrect majority
answer on just over one third of the critical trials.
Very high considering the unambiguous and easy nature of the task.
Within the 37%, there were wide individual differences as 5% conformed on every critical trial yet 25%
remained completely independent, going against the majority and giving the correct answer on all 12 trials
Asch's research suggests that people tend to conform to a
majority group so that they don't stand out from the crowd
Evaluation of Asch's Research
- Low Temporal Validity
McCarthyism
During this era (1950s), thousands of Americans were accused of being Communists or
communist sympathisers and became the subject of questioning before the government
This would have made people a lot more
reluctant to stand out from the crowd
- Population Validity
The participants in this study were all American male students
Androcentric study
As this is only a small percentage of the people
in America, the results from the study cannot be
generalised to a wider population that includes females
Low ecological validity
- Ethics
Deception
The participants were not informed about what the
experiement would test them on whether they conform or not
Justified as experiment would not work otherwise
+ Lab Experiment
Easy to repeat (Test - Retest)
More reliability
- Perrin & Spencer
Replicated Asch's study
In their initial study, they obtained only
one conforming result out of 396 trials
Used a group of science and engineering students
In a subesquent study, they found similar
levels of conformity to the original Asch study
Used youths on probation
Showed that the "Asch effect" is not a stable phenomenon
Smith & Bond
Meta-analysis of conformity studies
Using the Asch paradigm
Found that there has been a steady decline
in conformity since the original Asch study
Independent cultures tended to show lower
conformity rates than collectivist cultures
The more ambiguous the task, the higher
the levels of conformity rates in all cultures
Explanations of why
people Conform
Normative Social Influence
Based on the desire to be liked
Involves public compliance
Individual does not privately comply or change their views
Informational Social Influence
Based on the desire to be right
Involves an individual pubicly and privately changing their views
