Conjugate lateral eye movements as an index of hemispheric activation.

This study investigated the relationship between field independence and defense clustering as measured by the Defense Mechanisms Inventory and lateral eye movements. Subjects had previously been classified either as hysterical or obsessive style by the Rorschach and WAIS Comprehension subtest. Previous findings indicate that these subjects have a preferred direction of lateral eye movement in a questioning format (hysterical style = left; obsessive style = right). This study found no relationship between field independence and defense clustering and lateral eye movements. To the extent that eye gaze indexes hemispheric activation, we conclude that neither field independence nor defense clustering was related to hemispheric lateralization.

Hemispheric Activation

The present study was designed (1) to clarify whether lateral eye movements appear when eyes are closed as well as when they are open and (2) to examine some possible factors which may affect the phenomenon. Horizontal eye movements of 8 males and 8 females during reflection were recorded by means of electro-oculography. All the subjects showed fewer lateral eye movements in eyes-closed condition than in eyes-open condition, and neither the consistency of direction nor the effect of question types was replicated. These facts cannot be explained by the hemispheric activation hypothesis.

The Brain

Conjugate lateral eye movements induced by task-specific reflective thought were examined in 10 dextral men. Verbal and spatial stimuli designed to activate reflective thought in the left (verbal) and right (spatial) cerebral hemispheres of the brain were presented tachistoscopically in a darkened environment. Eye movements during reflective thought were monitored and scored using an infrared eye-tracking device. Reflective thought induced by the spatial task produced significantly more leftward conjugate lateral eye movement. The verbal task tended to produce more rightward and upward movements. The results are viewed as consistent with a task-specific brain-hemispheric activation model of contralateral conjugate eye movements during reflective thought.
