Left cerebral dominance for bilateral simultaneous sensory stimulation?
Hom and Reitan (1982) reported findings with respect to sensorimotor deficits in groups with lateralized cerebral lesions, but evaluated the results only within a framework that related cerebral dominance to deficits that resulted from lateralized lesions. Some of the variables they studied, however, depend upon evidence of retention of functions by one hemisphere under conditions of distracting input. While the right cerebral hemisphere appears to be dominant for tactile-perceptual abilities in terms of resulting deficits, the present study suggests that the left cerebral hemisphere is dominant for certain non-language functions that reflect maintenance of sensory-perceptual abilities under conditions of distracting stimuli.
