Asch 1955; Procedures
- Research was an observation
carried out under controlled
conditions.
- Sample
- 123 naïve (true)
pps collected by
volunteer
sampling
- They were all male from 3 USA colleges
- Placing 1 true pp into a group of 7-9
confederates
- The research involved;
- Seating them second to last in
the row so they can hear the
answers of the confederates
- Showing the pps a series of lines - a
standard line and 3 separate lines (all
with difference of between 3/4 of an inch
and 1"3/4
- Asking pps to match the standard line
to one of the 3 lines, where the answer
was always obvious, aloud in front of
others.
- There were 18 trials for each group and on 12
"critical" trials, all the confederates called out the
wrong answer.
- Asch introduced some variations
1) He vaired the size of the
confederate group from 1 - 15 2)
He allowed one confederate to
always answer truthfully. 3) A
confederate who gave wrong, but
different answers to other
confederates
- He also interviewed pps to see why they conformed
- Ethical Issues
- Debreifed his pps and explained the true purpose of his
research
