Abstract
Given previous indications of callosal damage and
dysfunction in multiple sclerosis (MS; e.g., Huber et
al.,1987; Jacobson, Deppe & Murray, 1983), it was
hypothesized that people with the disorder would show
impairment of interhemispheric transfer. People with MS
(n=20) and neurologically intact control subjects (n=23)
were administered six tests thought to address efficiency of
interhemispheric transfer. The praxis and tactile naming
tests were eliminated from statistical analyses because of
ceiling effects. Univariate analyses of the remaining
variables (verbal dichotic listening, visual half-field
tachistoscopic reading, tactile localization and replication
of hand postures) yielded results consistent with the
hypothesis that MS patients would show impairment of
interhemispheric communication, although a floor effect was
noted on the dichotic listening measure. Clinical and
empirical implications are discussed.
