ABSTRACT
Many tasks can be performed reasonably well by both cerebral hemispheres, although the hemispheres are biased to handle the tasks in qualitatively different ways. J. B. Hellige et al. had right-handed university students identify visually presented consonant-vowel-consonant (CVC) stimuli, with the CVC on each trial being presented briefly to the left visual field, to the right visual field, or to both visual fields and hemispheres simultaneously. This chapter deals with the observation that, for many tasks, the left and right cerebral hemispheres of humans are biased toward qualitatively different modes of processing, which led to questions about the mode of processing that emerges when both hemispheres have an equal opportunity to process incoming stimulus information. Even when CVCs are oriented vertically, there is individual variation in whether the qualitative error pattern on redundant bilateral and center trials is more similar to the pattern obtained on left visual field trials or to the pattern obtained on right visual field trials.
