Changes in verbal-performance IQ discrepancy scores after left hemisphere EEG frequency control training: A pilot report

A pilot investigation was conducted to determine the effect of left hemisphere EEG frequency control training (shifting from 8-13 Hz to 13-28 Hz activity and back) on boys with a verbal IQ 15 or more points below their performance IQ on the WISC-R. The findings suggested that specific effects may be elicited by specific training; i.e., verbal abilities increase and the verbal performance discrepancy narrows.
