  • Title: Lateral eye movements during verbal and nonverbal dichotic listening.
    Author: Lefevre E, Starck R, Lambert WE, Genesee F.
    Journal: Percept Mot Skills; 1977 Jun; 44(3 Pt 2):1115-22. PubMed ID: 887367.
    Abstract:
    A dichotic listening paradigm was used to study the relation of eye movement to cerebral lateralization. The eye movements of right-handed subjects were recorded during verbal and nonverbal dichotic-listening tasks. Subjects given a verbal dichotic-listening task made significantly more rightward than leftward eye movements and showed more accuracy and speed in processing information presented to the right than to the left ear. Subjects given a nonverbal dichotic-listening task made significantly more leftward eye movements and processed better information presented to the left ear. These findings suggest a potentially strong link between the direction of lateral eye movement during dichotic listening tasks and left- and right-ear advantages in performance on such tasks. They also suggest that both eye movement and ear performance may be related to cerebral laterality and when examined in combination both could provide valuable information for the further study of hemispheric specialization.
