The ability to communicate with written language is critical for success in school and in the workplace. Unfortunately, many children suffer from developmental dysgraphia―impairment in acquiring spelling or handwriting skills―and this form of impairment has received relatively little attention from researchers and educators. This volume brings together, for the first time, theoretically grounded and methodologically rigorous research on developmental dysgraphia, presented alongside reviews of the typical development of spelling and writing skills. Leading experts on writing and dysgraphia shed light on different types of impairments that can affect the learning of spelling and writing skills, and provide insights into the typical development of these skills. The volume, which contributes both to the basic science of literacy and to the applied science of diagnosing and treating developmental dysgraphia, should interest researchers, educators, and clinicians. This book was originally published as a special issue of Cognitive Neuropsychology.
