Sommario/riassunto |

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 Dyslexia, Reading and the Brain. 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: th |
