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.enAvailable to the World Wide WebMultiple sclerosisPsychological aspectsThesis
