The Senses Considered as Perceptual Systems
Dr. Gibson does not treat of the different senses as mere producers of visual, auditory, tactual, or other sensations. Rather, he regards them as active seeking mechanisms for looking, listening, touching, and the like. This means that the emphasis is on explanations of how we are able to have the constant perceptions that we need for effective action and avoidance of physical harm in our everyday lives. The author clearly supports his view that the perception of reality is not something assembled or computed by the brain from an ever-varying kaleidoscope of sensations. He emphasizes the importance of regarding the different perceptual systems not only as active, but also interrelated.
