This volume presents the latest advances in understanding attention: its anatomy, circuitry, functions, and deficits. Outstanding investigators have written brief yet substantive chapters in which they not only summarize key findings but also illuminate their goals and the directions their research is taking. Coverage includes different cognitive models of attention; knowledge emerging from functional imaging and genetic studies; and neurophysiological, developmental, and neuropsychological approaches. Emerging knowledge is presented on processes that impair or alter attention, and clinical implications are discussed. Linking many levels of analysis, and featuring over 100 illustrations, the book moves us closer to a coherent view of the attentional system and the key role it plays in everyday life.
