Performance of Deaf versus Hearing Individuals on a Visual Hemifield Task.
Johnson, Jeanne M.; Ruder, Kenneth F.
A study compared the performance of congenitally deaf signers (N=39) and hearing individuals (N=39) on a bilateral tachistoscopic task. Subjects were exposed to pretested linguistic and nonlinguistic stimuli during the task. Analysis of response time indicated that deaf subjects were slower to respond than were hearing subjects across all categories of stimuli. Analysis of accuracy revealed a significant right visual field preference for deaf subjects across all stimulus types; no lateral preference was found for hearing subjects in relation to stimulus type. The findings suggest that strategy factors are a major influence on performance and that auditory experience is not prerequisite to a finding of lateral preference on a behavioral task. (Author/CB)
