Dyslexia is a learning difficulty which affects the ability to adopt the automatic reflexes needed to read and write. Several studies have sought to identify the source of the problems encountered by individuals with dyslexia when they read. Little attention, however, has been paid to the mechanisms involved in writing. Researchers have recently looked at the purely motor aspects of writing in children diagnosed with dyslexia. Their results show that orthographic processing in children with dyslexia is so laborious that it can modify or impair writing skills, despite the absence of dysgraphia in these children.
