Phonological Dyslexia

This special issue describes numerous cases of phonological dyslexia, including a developmental case which has been studied in depth, and two cases of the disorder in Japanese readers.

Phonological dyslexia is a form of reading disorder in which the ability to read unfamiliar words, or pronounceable non-words, is selectively deficient. It occurs as both a developmental and an acquired dyslexia. The disorder therefore has implications for our understanding both of how children learn to read and of the architecture of the reading system used for normal skilled reading. This special issue describes numerous cases of phonological dyslexia, including a developmental case which has been studied in depth, and the first two published cases of the disorder in Japanese readers. The implications of data from acquired phonological dyslexia for computational models of reading the DRC and Reggia-Berndt dual-route models, and the parallel-distributed-processing model of Plaut and colleagues are discussed.
