ABSTRACT: The purpose of this study was to correlate the Revised Movement Imagery Questionnaire (MIQ-R) with lower and upper alpha power to determine the validity of alpha activity as a measure of imagery ability. EEG activity was recorded from 30 right-handed volunteers. Results revealed that lower alpha activity was significantly correlated (p<.01) with MIQ-R kinesthetic subscale at both the right and left parietal sites and lower alpha activity was significantly correlated (p<.05) with MIQ-R visual subscale at the right and left occipital and parietal regions. The results support previous research showing that both left and right hemispheres are activated during imagery processing. These findings corroborate the idea that a verbal component is involved in imagery rehearsal.
