Social Influence - Asch - Baseline study Flashcards
Solomon Asch Aims (1951)
devised a procedure to measure the extent that people conformed to the opinions of others, even when in a situation when the answer was clearly wrong.
procedure variable 1 - Group size
(1955) Asch extended his baseline study and varied the number of confederates in each group between 1 and 15 (total group size between 2 and 16)
Who?
Participants - 123 American Male undergraduates
Procedure
Tested individually, sitting last or next to last in a group of 6-8 confederates.
Shown two large cards.
One had a standard line.
The other three comparison lines.
One line the same as the standard line with the other two lines clearly different.
Each group member asked which of the three lines matched the standard.
18 Trials of involving different cards.
How many?
Sitting where?
Sitting last or next to last in a group of 6-8 confederates.
Findings of variable 1 - Group size
The relationship between group size and level of conformity was curvilinear.
If there were two confederates, conformity to the wrong answer was 13.6%.
When there were three confederates, conformity rose to 31.8%.
Above three confederates, confederates rate levelled off.
Adding more than three confederates made a little difference.
Explanation of Procedure variable 1 - Group size
People very sensitive to opinions of other people because just one confederate was enough to sway opinion.
Procedure of variable 2 - Unanimity
Asch added the presence of a non-conforming person to see if they would effect the naive participants conformity.
Added a confederate who disagreed with the other confederates.
Findings of variable 2 - Unanimity
In one variation of the study this person gave the right answer and in another variation they gave the wrong.
in the presence of a dissenter the genuine participant conformed less often.
the rate decreased to less than a quarter of the level it was when the majority was unanimous.
Explanation of Variable 2 - Unanimity
the presence of a dissenter appeared to free the naive participant to behave more independently.
Procedure of variable 3 - Task difficulty
Asch increased the difficulty of the line - judging task by making the stimulus line and the comparison lines more similar to each other in length.
This meant it became harder to distinguish the right line.
Findings of variable 3 - Task difficulty
Asch found that conformity increased .
It may be that the situation is more ambiguous. when the task becomes harder.
Explanation of variable 3 - Task difficulty
It is natural to look to other people for guidance and assume that they are right and you are wrong. (ISI)
Evaluation - one limitation - artificial tasks
Participants knew they were in a research study. The task was trivial and there was no reason not to conform.
Evaluation - one limitation - Fiske (2014)
Argued that Asch’s groups were not ‘very groupy’
not like real life
