key studies Flashcards
Asch AO1
Procedure: 123 American men in groups with 7 other confederates, had to out loud say what line they thought was most similar, confederates gave wrong answer 12/18 of the trials
Results: av conformity 37% conformed at least once 75%
Asch AO3 limitations (4)
- lacked population validity, all were white males of a similar age group
- low ecological validity as the task wasn’t one you would do in real life and the groups weren’t representative of real life either
- demand characteristics, they new they were in an experiment and may have been suspicious of oddness of task
- ethical issue as the participant were decided
Asch AO3 strengths
supported by other studies, participants were asked to perform easy and hard maths questions, answers were given by three other ‘participants’, the naive participant conformed more on harder maths questions, this supports task difficulty affects conformity
Zimbardo AO1 procedure
Procedure: 21 students who were assessed as emotionaly stable were randomnly assigned to prison/gaurd role and encouraged to conform through instructions about behavoir and uniform and given numbers
Zimbardo AO1 resutls
Gaurds took up role with enthusiams, 1/3 brutal 1/3 sypmathetic
By day two the gaurds rebelled very brutalistic often demanding head counts early in the morning
Zimbardo AO3 strengths
Internal validity, had control over IV through personality test and randomisation so can assume behaviour is from the role
When writing the answer privately what did conformity go down to
13%
Asch baseline results
On average pps agreed with the wrong answer 37% of the time, 25% never confirmed
Group size variation results
At 3 confederates conformity was at 32% but rose very mildly after up to 15
Conformity rate of 3 confederates
32%
Zimbardo A03 limitations (2)
- Lack of realism, only pretending to be in the role, not a real prison, this doesn’t tell of about conformity in actual prisons (counter point they felt it was a real prison and 90% of convo were abt prison life)
- Exaggeration the power of roles minimised the influence of dispostional factors as only 1/3 were brutal and could resist
- ethical issues
- lack of external validity small sample of American men
The bad ethics in Zimbardo
• participants right to withdraw
• fully informed consent
• no protection from harm
Milligram research support
- real puppy shock, 54% of men and 100% of women obeyed
- field experiment where twice as likely to pick up litter if asked by a security guard uniform
