Visual information processing in humans with intellectual disabilities and in animals is presented. This book examines key questions in cognitive science addressing the manner in which environment is represented by the organism, and thus relates to how knowledge about the world is gleaned, providing implications for theories of action and decision making. According to the authors, it has become apparent that the distinction between perceptual and cognitive processes is not always a clear one, and that these processes interact in critical ways in underlying complex behavioral repertoires.
