Do you need to recognize an object to know how to handle it? Why do some amputees continue to feel their arm even though it is absent? Why do some people see colours when they read or hear words? ‘Perceiving’ considers these questions and then provides the background information to answer them. It explains that the brain is not a single pathway from input to output, but that there are separate pathways and that pathways diverge. The different regions of the brain—such as the ventral and dorsal systems and primary sensory area—are explained in terms of how they are used for the recognition and classification of objects, and for perceptual awareness.
