Abstract

The aim of this study was to investigate the functional speech lateralization in adult dyslexic readers whose native language is Hebrew. Event-related potentials (ERPs) were recorded from 22 non-impaired readers and 18 dyslexic readers performing dichotic nonsense consonant-vowel (CV) syllables and dichotic vowels target detection tasks. Evidence of altered patterns of behavioral speech lateralization was found in the dyslexic group mainly for the CV syllables task. The latencies and amplitudes of the N1–P2 ERPs complex produced by the dichotic CV syllables and dichotic vowels tasks were deviant as well. The findings suggest a differently organized auditory system with altered speech lateralization in adult dyslexic readers.
