It is nearly a hundred years since Pringle Morgan first published his famous account of Percy, a boy of 14 who could only with difficulty spell out words of one syllable, who wrote his name as "Precy" and did not notice the mistake until his attention was called to it more than once. Yet the school teacher who taught him for some years says that he would be the smartest lad in the school if the instructions were entirely oral. "Dyslexia: A Hundred Years On" provides an overview of the field. It traces the historical influences, examines the contributions of various disciplines, reviews current research, outlines teaching methods and programmes, and discusses continuing disputes. In the authors' own judgements the evidence points to there being some individuals who display an anomaly of development which results in a weakness at the "phonological" level - that is, in converting things and events in the world into their spoken equivalent: the dyslexia syndrome is a consequence of this weakness. This book will be a useful resource for trainee and practising teachers; students and practitioners in special needs, remedial education and educational psychology and all those interested in dyslexia.
