Effect of presentation time and Gestalt principles of proximity, similarity, and closure on perceptual accuracy.

Abstract

The present study investigated Gestalt principles of proximity, similarity and closure. 32 subjects reproduced distances between dots and lines. Two stimulus exposure times were used. Time was significant for proximity, similarity, and closure. Type of distance estimated was significant for proximity and closure and the interaction of time and type of distance was significant for similarity. Most accurate estimations were consistently found for fast exposure times, and internal distances were estimated more accurately than external distances.
