Dominant direction of conjugate lateral eye movements and responsiveness to facial and verbal cues

Abstract

Responsiveness to facial versus verbal cues as a function of dominant direction of conjugate lateral eye movements and sex was tested in a 2 X 2 analysis of variance design. Ss were 81 student volunteers. Right-movers (n = 33) were more responsive to verbal cues; left-movers (n = 45) were more responsive to facial cues (p less than .05). The results are consistent with the hypothesized link between conjugate lateral eye movements and functional asymmetry of the cerebral hemispheres. Males were more responsive to verbal cues; females were more responsive to facial cues (p less than .05). Data relevant to reliability of the eye movements, the relationship between sex and eye movements, and the relationship between type of question and eye movements are also presented.
