CORRELATION OF FREQUENCY SPECTRA OF AVERAGED VISUAL EVOKED POTENTIALS WITH VERBAL INTELLIGENCE

ALTHOUGH numerous attempts have been made to establish relationships between measures of the EEG and intelligence, much of the work has resulted in contradictory conclusions. Demonstrable relations between several measures of the EEG and test intelligence have been found, particularly in subjects who were feeble-minded or brain damaged1. Little evidence has, however, been found to support this relationship in normal adults, and even in brain damaged and feeble-minded subjects the relationship may be spurious2. © 1969 Nature Publishing Group.
