Lateral imbalance of the visual field affects conjugate lateral eye movement: an experimental demonstration

Baker (1989) reported a serendipitous observation: When subjects were seated closer to the left than to the right wall of the room, conjugate lateral eye movement (CLEM) following a question involving shared eye gaze was predominantly toward the right. This study sought to verify this observation. In the asymmetrical condition, half the subjects sat next to the right wall and the other half sat next to the left wall. In the symmetrical condition, each subject was seated equidistantly from the right and left walls. More CLEM was found in asymmetrical conditions in the direction toward the center of the wall the subject faced, a finding consistent with the earlier formulations and findings of the sensory-tonic theory of perception.
