Category-dependent processing of rapid auditory stimuli in dyslexia

Developmental dyslexia is a specific impairment in learning to read, and difficulties with accurate and fluent word recognition, spelling and decoding abilities. Disturbances concerning manipulation of phonetic language units, visual processing in the magnocellular pathway and skill automatization seem to be the major deficits. Recent studies demonstrate that rapid temporal features of the auditory speech signal during differentiation of speech sounds at phoneme level are preferentially processed by the left hemisphere, whereas right-sided regions seem to be specifically involved in the analysis of slow acoustic…
