The influence of depression on the cerebral hemispheric motor functioning of 40 right-handed women, half of whom had been classified as depressed, the other half as nondepressed, was examined. The depressed women were also characterized by elevated state and trait anxiety, suggestive of an anxious-depressive state with heightened arousal. A hand dynamometer was used as a standardized measure of hemispheric motor functioning such as hand-grip strength, perseveration, and fatigue. Primary findings indicated that depressed women displayed significantly less perseveration at the left hand than did nondepressed women, but a nonsignificant trend only was noted for less perseveration at the right hand. These results suggest possible differential arousal of the left and right cerebral hemispheres in this sample of anxious-depressed women and are discussed in terms of arousal theory.
研究了抑郁症对40名右利手女性大脑半球运动功能的影响,其中一半被归类为抑郁症患者,另一半为非抑郁症患者。抑郁症女性还表现出状态焦虑和特质焦虑升高,提示存在伴有觉醒增强的焦虑抑郁状态。使用握力计作为大脑半球运动功能的标准化测量指标,如握力、持续性和疲劳度。主要研究结果表明,与非抑郁症女性相比,抑郁症女性左手的持续性显著降低,但右手持续性降低仅呈现出不显著的趋势。这些结果表明,在这个焦虑抑郁女性样本中,左右大脑半球可能存在不同的觉醒状态,并根据觉醒理论进行了讨论。
