The anterior regions of the left and right cerebral hemispheres have been posited to be specialized for expression and experience of approach and withdrawal processes, respectively. Much of the evidence supporting this hypothesis has been obtained by use of the anterior asymmetry in electroencephalographic alpha activity. In most of this research, however, motivational direction has been confounded with affective valence such that, for instance, approach motivation relates positively with positive affect. In the present research, we tested the hypothesis that dispositional anger, an approach-related motivational tendency with negative valence, would be associated with greater left- than right-anterior activity. Results supported the hypothesis, suggesting that the anterior asymmetry varies as a function of motivational direction rather than affective valence.
左、右大脑半球的前部区域被认为分别专门负责趋近和回避过程的表达与体验。支持这一假设的大部分证据是通过脑电图α活动的前部不对称性获得的。然而，在大多数此类研究中，动机方向与情感效价相互混淆，例如，趋近动机与积极情感呈正相关。在本研究中，我们测试了这样一个假设：特质性愤怒，一种具有负性效价的与趋近相关的动机倾向，与左前部活动大于右前部活动有关。结果支持了这一假设，表明前部不对称性随动机方向而非情感效价而变化。
