Neuropsychology has developed in recent years into an area of central concern for a range of disciplines. Major advances have taken place in both brain imaging techniques and the cognitive modelling of the impairments following brain damage, and these promise a wider understanding of the nature of the representation of cognition and behaviour in the damaged brain. This volume is a survey of the main behavioural characteristics or symptoms of aphasia. It presents a series of essays on the history and current developments in this field of neuropsychological research. Contributors discuss recovery, rehabilitation and other contemporary issues. The work should be of interest to neuropsychologists, neurolinguists, cognitive psychologists and students and researchers involved in speech pathology and the care of the brain-damaged.
