The direction a person gazes while pondering a question has been shown to correlate with hemispheric activation. Verbal questions tend to elicit Lateral Eye Movements (LEMs) opposite the verbal hemisphere; nonverbal questions tend to elicit LEMs opposite the nonverbal hemisphere. Twenty-four right-handed male college students were observed for right, left or no LEMs via electrooculogram following verbal and nonverbal questions presented via slide projection and tape recording in a 2x2 factorial design. Results supported previous studies in that frequency of eye movement was greater for verbal than for spatial questions when they were presented via tape recording. There was no significant difference in the direction of LEMs following tape recorded verbal and spatial questions. Slide projected questions provided significantly stronger left LEM stimulation than tape recorded questions suggesting that visual presentation may enhance the effectiveness of questions in activating the right (nonverbal) brain hemisphere.
