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 × 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 < .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 < .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.
