Despite the wealth of literature available on the subject of dyslexia, there is little that explores the subject beyond a single theoretical framework. The need for a comprehensive review of the literature by both researchers and practitioners from different fields and theoretical backgrounds is the central motivation behind . By combining the existing fragmented and one-sided accounts, Alan Beaton has created a sourcebook that provides the much-needed basis for a more integrated and holistic approach to dyslexia.The book is divided into two sections: the first, The Cognitive Context, outlines the theoretical context of normal reading development and introduces the role of phonological awareness and the relation between dyslexia and IQ. Section two, The Biological Context, provides an explanation of the genetic background as well as exploring hormonal theories and the visual aspects of dyslexia. By including both historical theories and some of the most recent developments, succeeds in presenting the reader with a balanced and unbiased overview of the current thinking and achieves a unique breadth and depth of coverage. The comprehensive coverage and impartial approach mean that this sourcebook will prove an invaluable resource for anyone involved in study, research or practice in the fields of reading and dyslexia.
