Studies with Low Ecological Validity

Tajfel (Minimal groups)

This experiment measures prejudice through an artificial task (allocating points to matrices)

It ought to be pointed out that both this experiment benefitted from being artificial. It established that prejudice occurs simply through the creation of an in-group and an out-group.

Bandura (Aggression)

Again this experiment is artificial. A child is exposed to an adult being aggressive towards a large BOBO doll. This would normally be considered unusual behaviour!
