High Ability Studies, v19 n2 p131-139 Dec 2008
Using time-frequency analysis techniques to investigate the event-related low-frequency (delta: 0.5-4 Hz; theta: 4-8 Hz) activity of auditory event-related potentials (ERPs) data of highly and average intelligent children, 18 intellectually gifted children, and 18 intellectually average children participated the present study. Present findings show that intellectually gifted children had significantly larger delta activity than their normal peers in mismatch negativity (MMN) component, while in P3a component, which originates from stimulus-driven frontal attention mechanisms during task processing, intellectually gifted children had both significantly larger delta and theta activities than their normal peers. The present findings further supported that low-frequency brain activity could be regarded as the basis of intelligence and cognitive functions, and spectral EEG time-frequency analysis technique should be used to explore some new aspects of brain activity relating to intelligence.
