-6 confederates and 1 ppt in were asked to publicly match a stimulus line to a choice of three alternatives
-The real pps was always seated and always answered near the end after most confederates had given their answer
-Initially 6 control trials were conducted where confederates gave the correct answer. Then in 12 critical trials confederates were instructed give the incorrect answer unanimously
-In the pilot study ppl were tested individually on the the lines the success rate was over 99%. Which shows the task was easy and the right answer was obvious.
-Yet in the actual experiment 75% of pps conformed at least once and 5% conformed every time and the overall conformity rate was 32%
-Asch's study showed a significant degree of conformity
-Asch's research suggests that people will conform due to Normativesocialinfluence (NSI), they conform for social approval, avoiding rejection or being seen as an outcast
-There were some clear individual differences e.g. 25% never conformed at all and 5% conformed the whole time.
-There was little conformity when the majority was only one or two people.
-However under the pressure of a majority of three conformity
increased to 33%.
-BUT further increases did not increase the levels of conformity.
-This suggests that the presence of a small, unanimous group has a strong social pressure, but beyond a certain point, the group size doesn't proportionally increase this pressure.
-Evidence against Asch comes from Perrin & Spencer (1981): -They found that when they repeated the Asch study in Britain many years later, only 1 person conformed in 396 trials.
-It was concluded people don't always conform as much as Asch's original study suggested.
-This is a problem as Asch's study may be seen as 'a child of its time'.
-This could be said to be lacking temporal validity.
-Another strength of Asch's research is that the study was easy to replicate:
-This means that the controlled setting made it easier to repeat the research in exactly the same way, adjusting variables each time to test their influence on conformity.
-For example, Asch was able to keep everything the same (standardised), but change variables such as the size of the group and the difficulty of the task.
-This is positive as it allowed Asch's research to test which variables affect conformity the most to gain a better understanding.
