Each chapter represents a personal account of a reading disorder through which details of the features of the disorder, methods used for testing, and theoretical accounts are illustrated. Controversies are explained, theories evaluated and anomalies pointed out. From this emerges a picture of the central properties of each disorder and the contribution of each to our understanding of the reading system as a whole. However, the picture is not complete: loose threads tantalise, some findings are hard to explain, and some newly controversial theories are put forward. The intention is to provide information that will help to equip the reader with the knowledge and expertise necessary to take the study of these reading disorders forward.
