[Dyslexia: a continuing developmental approach]

After reviewing the various theories trying to explain the different forms of dyslexia, the author attempts to show how studying the different stages in learning to read and the processes brought into play at each stage allow for a different approach to the problem. Based on work done by Utha Frith, the author sets out three main strategies that go together and follow each other in developing reading skills: recognizing sigh-symbols, sound units and spelling patterns. He analyzes the implied processes and considers six different kinds of dyslexia based on on-going genetic analysis. He suggests that this new approach toward dyslexia favors new tools in research and in creating support programs for dyslexic children.
