The document discusses the cognitive perspective in psychology. It focuses on gestalt psychology, which emphasized the importance of sensory wholes and the dynamic nature of visual perception. Gestalt psychologists like Max Wertheimer, Wolfgang Köhler, and Kurt Koffka established principles of perception including proximity, similarity, closure, continuation, and figure/ground perception. They believed perception is organized according to the simplest form possible, in contrast to behaviorism which had an external and mechanistic focus. The cognitive perspective highlighted the importance of mental processes and products in learning.
