title: Cerebral asymmetry in facial affect perception by women: neuropsychological effects of depressed mood.
abstract: 40 right-handed women, half of whom had been classified with depressed mood and the other half as nondepressed, participated in a tachistoscopic study of the influence of depressed mood on the cerebral hemispheric processing of Ekman and Friesen's 1976 happy, sad, and neutral emotional faces using a forced-choice reaction-time paradigm with only happy and sad alternatives as response manipulanda. The women with depressed mood were also characterized by elevated scores on both state and trait anxiety, suggestive of an anxious-depressive state with heightened arousal. Primary findings for the tachistoscopic data indicated that women with depressed mood as compared to nondepressed women displayed significantly faster reaction times to sad faces presented in the right visual field and happy faces presented in the left visual field. These results are suggestive of differential arousal of both the left and right cerebral hemispheres in this sample of anxious-depressed women and are discussed in light of arousal theory.
