title: Response preparation and cognitive control of highly intelligent children: a Go-Nogo event-related potential study.
abstract: A cued Go-Nogo task was employed to explore the neural correlation among response preparation, cognitive control and intelligence in two groups of early adolescents with different intellectual levels using event-related potential (ERP) technique. Behavioral results indicated that the gifted children had better cognitive control performances with higher correct hit rate and lower commission error rate than the average children. Electrophysiological results further showed that the gifted children elicited efficient cue-P2 response for automatic cue detection and stronger cue-P3 activation for cue evaluation. Moreover, gifted children induced faster N2 and Nogo-P3 responses for conflict monitoring and inhibition processing and stronger P3 activation for attentional control. The current results supported the neural efficiency hypothesis of intelligence and further shed light on the close relationship among response preparation, cognitive control and human intelligence.
