dc.description.abstractForty right-handed women, half who had been classified as depressed, the other half nondepressed, participated in a tachistoscopic study of the influence of depression on the cerebral hemispheric processing of Ekman and Friesen’s (1976) happy, sad, and neutral emotional faces. A dynamometer was also used as a standardized measure of hemispheric motor functioning such as hand grip strength, perseveration, and fatigue. Results indicated that the depressed women were characterized by elevated levels of both depression and anxiety, suggestive of an agitated, depressive state with heightened arousal. Further, depressed as compared to nondepressed women displayed significantly faster reaction times to sad faces presented their right visual fields and happy faces presented their left visual fields. For the dynamometer data, primary findings indicated that depressed women displayed significantly less perseveration at the left hand as compared to nondepressed women. There was also a trend for depressed as opposed to nondepressed women to show less perseveration at the right hand. These findings from both the tachistoscope and dynamometer data are suggestive of differential arousal of both the left and right cerebral hemispheres and are discussed in light of arousal theory.en
