The journal Cognitive Neuropsychology began publication in 1984. In 2004 a special symposium was held at the annual European Workshop on Cognitive Neuropsychology at Bressanone to take stock of the developments in cognitive neuropsychology represented by the first twenty volumes of the journal, and this book is the result. In the book, prominent cognitive neuropsychologists provide state-of-the-art overviews of what cognitive neuropsychology has told us about the normal mechanisms of conceptual representation, spoken word production, the comprehension and construction of sentences, reading, spelling, memory, visual attention visual object recognition, and everyday action and planning. Key topics that are covered include computational cognitive neuropsychology, the relationship of cognitive neuropsychology to cognitive neuroscience, modularity, and the current status of such traditional features of cognitive neuropsychology as the rejection of group studies in favour of single case studies and the rejection of the study of syndromes in favour of the study of symptoms.
