This book is about perception, which is the psychological process that is triggered in us when we look at something. Through perception, we give meaning to the sensory inputs that come from the outside. To investigate this fascinating and complex process, the author refers to Gestalt theory, a school of thought founded in 1912 by the Czech psychologist Max Wertheimer, and later developed by Wolfgang Köhler and Kurt Koffka. The theory is based on perception and experience.
According to Gestalt, when we perceive the external world, we do not simply grasp the sum of the various stimuli before us; we perceive the whole, which is something more than the simple association of single elements. Let's take the example of music: when we listen to a song, we don't hear the individual notes, but the whole tune. In the same way, when you look at the face of someone you love, you see more than a combination of a nose, mouth, chin, eyes and ears. We perceive it in its totality. In fact, Gestalt Theory emphasises that the whole of anything is greater than its parts.
The purpose of this book is to apply these principles to the study of the visual arts. According to Arnheim, art and psychology are closely connected. There have been many psychological studies on the creation of art and the creative process itself. When we see an image, perceptive mechanisms are triggered which are the result of personal experiences and cultural conventions. This brings us to the assumption that the study of art is also the study of human beings.
