This work provides a reference for outlining the theoretical basis for visual, perceptual and cognitive deficits, as well as specific procedures for the evaluation and treatment of these deficits. It explains each deficit and provides step-by-step testing techniques along with complete treatment guidelines. The author has included recent theoretical information to back up evaluation and treatment decisions that are discussed. All the sections have been updated to represent the current information available. This text now provides information for a more holistic approach as well as identifies subcomponent skills. The text features: both top-down and bottom-up approaches to evaluation and treatment; topics divided into categories for clarity, such as visual processing and discrimination skills, body scheme difficulties, executive functions and motor planning; and is referenced for further research on specific topics.
