使用行为和心理生理学方法研究了情绪处理的右半球专门化。研究人员向50名大学生展示了一些幻灯片，这些幻灯片描绘了负面情绪和中性场景，这些场景被短暂地偏侧到大脑的左右半球，并被要求将每一个场景归类为情绪或中性。脉搏容积和心率（HR）测量生理处理和反应时间测量认知处理。最大的血管收缩反应和HR减速获得的情绪项目在右半球。然而，反应时间未能显示右半球的优势，在知觉/认知处理，而不是表现出最慢的反应，情绪刺激提交给右半球的证据，左半球的能力。自主反应中的选择性右半球激活，加上右半球在认知任务中缺乏专业化，表明生理反应系统而不是感知/认知系统是右半球情绪优势的所在地。
Right hemisphere specialization for emotional processing was investigated using behavioral and psychophysiological methods. Fifty undergraduates were shown slides depicting negative emotional and neutral scenes briefly lateralized to the right or left cerebral hemispheres and asked to categorize each as emotional or neutral. Pulse volume and heart rate (HR) measured physiological processing and reaction time measured cognitive processing. The largest vasoconstriction responses and HR deceleration were obtained for emotional items in the right hemisphere. However, reaction time failed to show right hemisphere superiority in perceptual/cognitive processing, demonstrating instead slowest responses to emotional stimuli presented to the right hemisphere together with evidence for left hemisphere competence. Selective right hemispheric activation in autonomic responses, combined with the lack of right hemisphere specialization in the cognitive task, suggests that the physiological response system rather than the perceptual/cognitive system is the locus of the right hemisphere superiority for emotion.
