Five experiments involving American Sign Language (ASL) signs, English words and faces were carried out to investigate visual field asymmetries in congenitally deaf and hearing children. Hearing subjects demonstrated a significant right visual field superiority for the perception of moving (ASL) sign sequences and English words and a significant left visual field advantage for the processing of static (ASL) signs and faces. In contrast, deaf subjects showed a significant right visual field superiority on the face task. No significant visual field asymmetries were indicated by the deaf group on tasks involving (ASL) signs or English words. Subject performance, however, was consistent and reliable across different language tasks. The results are discussed in terms of their implications for underlying patterns of cerebral lateralization in the deaf.
