Aim: Whether context affects perception

Procedure

  • 64 students were shown visual scenes, like a kitchen for 2 seconds
  • They were then briefly shown an object and asked to identify it
  • They were either shown an appropriate context+object
  • Inappropriate context+similar object
  • Inappropriate context+different object
  • No Context at all

Results: Participants correctly identified the most objects after seeing an appropriate context and least after seeing an inappropriate context.
