Cross-modal matching and association abilities of the left and right hemispheres tested under intracarotid sodium amytal Pratt, L. Rachel
Anatomical and theoretical considerations, as well as experimental findings, have yielded conflicting points of view regarding the abilities of the right hemisphere in man to accomplish cross-modal transfer of Information. Auditory-visual cross-modal matching (CMM) and association (CMA) abilities of the left and right hemispheres (LH and RH) were tested, utilizing the Wada intracarotid sodium amytal technique. It was found that the RH performed slightly better on these tasks than the LH. Possible reasons for this RH advantage are discussed. These findings contrast with results of other techniques which indicate that the RH cannot perform CMM and CMA. The hypothesis that damage to one hemisphere interfers with the normal operations of the other hemisphere is discussed.
