研究表明，左前额叶皮层的活动与积极情感或接近动机有关，而右前额叶皮层的活动与消极情感或退缩动机有关。在过去的研究中，情绪效价（积极-消极）与动机方向（接近-退缩）相混淆，例如，所研究的情绪既积极又与接近有关。最近的研究表明，特质愤怒，一个负面的，但接近相关的情绪，与左前额叶活动增加和右前额叶活动减少，这表明前额叶不对称活动与动机方向，而不是情绪效价。本实验测试了状态诱导的愤怒是否与相对的左前额叶活动有关，以及这种前额叶活动是否也与攻击性有关。结果支持这些假设。
Research has demonstrated that left-prefrontal cortical activity is associated with positive affect, or approach motivation, and that right-prefrontal cortical activity is associated with negative affect, or withdrawal motivation. In past research, emotional valence (positive-negative) has been confounded with motivational direction (approach-withdrawal), such that, for instance, the only emotions examined were both positive and approach related. Recent research has demonstrated that trait anger, a negative but approach-related emotion, is associated with increased left-prefrontal and decreased right-prefrontal activity, suggesting that prefrontal asymmetrical activity is associated with motivational direction and not emotional valence. The present experiment tested whether state-induced anger is associated with relative left-prefrontal activity and whether this prefrontal activity is also associated with aggression. Results supported these hypotheses.
