33. Gestalt Psychology Principles of Visual Perception Principle of Proximity: We tend to group together things that are close to one another and more distant from other (similar) objects.

34. Principle of Proximity (Similar figures in closer proximity will be seen as a group)

37. Principle of Similarity (Similar figures will be seen as a group.) Do you see groups?

38. Principle of Similarity (Similar figures will be seen as a group.) Do you see groups?
