Eye-movement asymmetry and hemispheric function: an examination of individual differences.

The relationship between lateral eye movements and selected individual characteristics was examined in a group of 81 right-handed adult males. Ss answered 20 verbal and 20 visuospatial questions in one of three experimental conditions while their eye movements were being recorded electrically. Multiple regression analyses were used to predict the proportion of eye movements to the right on the basis of spatial and verbal test scores, questionnaire responses concerning imagery and verbal processes, a self-report measure of values and interests, and choice of academic major. No significant relationships were found. Even the most consistent "left movers" and "right movers" did not differ in the manner suggested by a model of eye-movement asymmetry based upon individual differences in cerebral function.
