Right-handed subjects tend to look to the left when answering affective questions. The relative shift in gaze from right to left is accentuated when the questions also involve spatial manipulation and attenuated when the questions require verbal manipulation. The data support the hypothesis that the right hemisphere has a special role in emotion in the intact brain, and that predictable patterning of hemispheric activity can occur when specific combinations of cognitive and affective processes interact.
惯用右手的受试者在回答情感问题时往往会看向左边。当问题还涉及空间操作时，从右到左的注视相对偏移会加剧；而当问题需要语言操作时，这种偏移则会减弱。这些数据支持了以下假设：在完整的大脑中，右半球在情绪方面具有特殊作用，并且当认知和情感过程的特定组合相互作用时，半球活动会出现可预测的模式。
