Administered phonological awareness and phoneme identification tasks to dyslexic children and chronological age (CA) and reading-level (RL) comparison groups. Found no real differences in categorical perception between dyslexic and RL groups; however, more dyslexics (7 of 25) had abnormal identification functions. Results suggest that some dyslexic children have perceptual deficit for speech that interferes with processing of phonological information. (EV)
