The purpose of the current research was to study the interhemispheric interaction in the brains of mathematically gifted youth, average ability adolescents, and college students. This study investigated the efficiency of interhemispheric interaction via the corpus callosum for brief displays of hierarchical stimuli under these conditions: (1) when both hemispheres have direct access to the visual information for performing global/local matches (i.e., bilateral redundant trials), (2) when the information necessary to perform such matches is divided between the visual-fields/hemispheres, thus forcing the hemispheres to exchange information to successfully perform the task (i.e., bilateral cooperative trials), and ...
