| Abstract: | The present study compared two group of subjects with intellectual disability. The 44 subjects in group 1 had equivalent verbal and performance IQs (67 and 64, respectively), while the 12 subjects in group 2 had an intellectual performance IQ which was ≥10 points above their verbal performance IQ (80 and 65, respectively). The second group showed an alpha peak at a higher frequency and an evoked potential closer to normality. The decrease in the voltage of the P300 wave in group 1 was especially significant. The cognitive evoked potentials were also different between the two groups. |
