P300 component of the auditory event-related potentials and dyslexia.
Ten normal children (mean age = 9 years) and 12 dyslexic children (mean age = 8.1 years) were compared for latency, amplitude and topographic distribution of both parameters of P300. We found a significant increase in P300 latency in the dyslexic group. Noteworthy is the increase in amplitude in the central parietal area in the control group. These facts and their incidence are discussed in the present study.
