The gestalt principles of perception – how do they explain how we not only sometimes perceive strange things, but also how we can appreciate works of art?

Why do we perceive these things?

Perceptual Set Experiment: go here to do the “Man on a horse” experiment I created. You can run this experiment on your friends, or even use it for a project in class. Have fun with it and let me know if you’ve got any feedback/suggestions. NOTE: The control condition is the “condition 1″ button (random pictures which are unrelated to the man on the horse). The experimental condition is the “condition 2″ button (pictures of animals which should help the viewer more easily see the man on the horse).

Here are a few sites which further explain some of the Gestalt principles of organization:
