Past studies have suggested important links between valence and perception and action in physical space. The present study aimed to test the associations between emotional valance for words or faces and manual responses in left- and right-handers. We employed a divided output (bimanual) reaction time paradigm in which participants had to discriminate emotional valance of words or faces presented on the center of the screen. The results revealed that right-handers were faster when responding to positive words or faces with their right hand and to negative words or faces with the left hand, whereas left-handers showed the opposite pattern. These results suggest that the association between space and valence depends on handedness, providing further evidence for the body-specificity hypothesis.
过去的研究表明，在物理空间中，价值和感知与行动之间存在着重要的联系。本研究旨在测试左右利手者对单词或面孔的情绪效价与手动反应之间的关联。我们采用了一种分裂输出（双手）反应时范式，其中参与者必须辨别屏幕中央呈现的单词或面孔的情绪效价。结果表明，右利手者用右手对积极的单词或面孔、用左手对消极的单词或面孔做出反应时更快，而左利手者则表现出相反的模式。这些结果表明，空间和效价之间的联系取决于利手性，为身体特异性假设提供了进一步的证据。
