Developmental dyslexics are shown to resemble acquired surface dyslexics but they are even more similar to younger children of equivalent reading ability. Also, it is argued that a complete understanding of the development of reading can come only from longitudinal investigations of development itself. Such studies demonstrate typical sequences of interactive growth of related skills. They show how reading changes in nature as it is learned and that a crucial early stage in its development is the adoption of an alphabetic reading strategy. The precursors of the phonological knowledge that forms the foundations of grapheme-phoneme reading are traced back through spelling and explicit phonological awareness to their source in implicit phonological awareness. Evidence is presented that the reading and spelling development of developmental dyslexics is limited by their prior failure to acquire this knowledge.Read More
