Validity - Asch (1955) Variations

• Ecological Validity: in lab experiments like these variation studies, this type of validity is low. The artificial setting does not represent real life.
• Population Validity: the samples in the variation studies do not represent of the wider population, so they lack population validity.
• Temporal Validity: the findings from the variation studies (1950s) may not reflect how people would behave today. Therefore they lack temporal validity.
• Mundane Realism: the tasks the participants were asked to complete do not reflect those they would experience in everyday life.
