Aschs study

• Asch's line judgement study

  • 123 naive male students
  • Told they were taking part in visual perception
  • Tested individually to see effect of pressure from majority on conformity levels
  • One naive participant placed in group with 6-8 confederates
  • Shown standard line and asked to match it to 3 comparison lines, aloud, from choice of 3
  • Task was an obvious answer
• Asch found that the confederates gave the wrong answer 12 times out of 18 critical trials
• The naive participant gave the wrong answer 36.8% of the time
• 75% of the naive participants conformed at least once
• 25% of participants never conformed
• Individuals are more likely to conform
