Asch's evaluation

• What is a weakness of Asch's study?

  It was only relevant at its time. This is a weakness as it lacks temporal validity, it is not relevant/accurate to today. Perrin and Spencer (1981) carried out Asch's study 25 years later with engineering students and only one student conformed in a total of 396 trials, showing Asch's study is no longer relevant. as results changed significantly.
• What is a weakness of Asch's study?

  It consisted of artificial tasks and situations. This is a weakness as participants knew they were being studied and so may have simply displayed demand characteristics. It also lacks ecological validity due to the artificial environment.
• What is a weakness of Asch's study?

  Only men were tested. This is a weakness as results are ungeneralisable to women. Also Asch carried out research in the USA, so results may not be generalised to other countries/cultures.
