First Published in 1990. How we perceive and respond to the visual image has been a traditional concern of psychologists, philosophers and art historians. Today, where the visual image increasingly permeates our everyday life and consciousness, the question becomes ever more relevant. How do we, for instance, instinctively ‘know’ what it is that a picture represents without having to be taught? How is it that we experience (aesthetic) pleasure in looking at certain pictures? How is it that we often want to talk about the pictures we look at? Such questions are currently asked by a wide range of disciplines, including: semiotics, psychoanalysis, anthropology, neuropsychology, and in general, contemporary critical analysis of the visual arts. Michael Stephan breaks new ground by linking the findings of these areas. Drawing on their common area of knowledge, he has developed a radically new theory of picture perception and aesthetic response, arguing that images can generate in us a complex pattern of mental changes, or transformations. This is because the left and right hemispheres of the brain do not always work in harmony, hence the wide-ranging nature of aesthetic response to distinct art forms. is essential reading to those seriously involved in linking the arts and cognitive sciences.
