Evidence from psychiatric patients has suggested that depressive affect may coincide with a decrement in the functioning of the right cerebral hemisphere. We have observed that college students who reported greater depression also reported less vivid imagery. Students undergoing experimental induction of depressive and euphoric moods in the laboratory showed an auditory attentional bias and impaired imagery during the depression condition, while their arithmetic task performance was unchanged. A second mood-induction experiment indicated a depressed mood to be characterized by asymmetrical EEG activation over the frontal lobes, with relatively greater activity in the right frontal region. These observations suggest that anterior regions of the brain may modulate the differential effects of emotional arousal on the information-processing capacities of the cerebral hemispheres.
来自精神病患者的证据表明，抑郁情绪可能与右脑功能减退同时出现。我们观察到，报告有更严重抑郁情绪的大学生也报告称其意象较不生动。在实验室中接受抑郁和欣快情绪实验诱导的学生，在抑郁状态下表现出听觉注意力偏向和意象受损，而他们的算术任务表现未变。第二项情绪诱导实验表明，抑郁情绪的特征是额叶的脑电图激活不对称，右侧额叶区域的活动相对更强。这些观察结果表明，大脑前部区域可能会调节情绪唤醒对大脑半球信息处理能力的不同影响。
