| Popis: | Despite a history of attempts, neuroscience has thus far failed to identify a validated biological determinant of behavioral intelligence. Cognitive variables such as selective attention, expectancy and information processing workload modulate the amplitude of evoked cortical potentials (EPs), thereby demonstrating the operation of cognitive neural adaptability. It seems reasonable to postulate that individual differences in this aspect of neural function could relate to individual differences in behavioral intelligence: the electrophysiologically adaptable brain should be the behaviorally bright brain.To test this hypothesis I gathered auditory EPs from 109 normal and 52 mentally retarded adults under three stimulation conditions (periodic, self, and random) designed to manipulate temporal expectancy.The normal adults showed a strong temporal expectancy effect on their EPs, giving smaller than average EPs to expected inputs and larger than average brain responses to unexpected stimuli. In contrast, the r... |
