American Journal of Physiology, 238, R3-R13) model of brain organization is that significant correlations between left-hemisphere (LH) and right-hemisphere (RH) measures indicate that the hemispheres are coupled together in a general system. Two formally similar visual-field (VF) reaction-time (RT) tasks, one a LH-right (R) VF and the other a RH-left (L) VF advantage task, were performed by 30 female and 30 male right-handers under single-task (zero load) and dual task (three or six consonants in memory) conditions. Expected letter load effects upon VF performances were obtained. Particularly for RT variability, correlations of measures lateralized to different hemispheres (i.e., LVF-RVF, LH and RH tasks) increased linearly as load increased, while correlations of measures lateralized to the same hemisphere (i.e., two LH tasks) did not. Bihemispheric cortical activation may playa role in this general system coupling caused by complexity or load. Females demonstrated greater interhemispheric coupling. @ 1992 Academic Press. Inc.
