我们使用反应启动任务研究了快乐和愤怒面部表情的运动规划和重新编程。响应信号命令产生有效或无效提示的面部表情。肌电图显示，在无效的试验中，抑制错误准备的表达和重新编程正确的表达需要付出性能代价。颧大肌的这些性能代价比皱眉肌大的大，这表明对后者有更好的控制。事件相关电位在或有负向变量中，在愤怒和快乐的初始准备中没有情绪特异性。在重新编程期间，愤怒伴随着更多的加工资源的分配，以抑制预先激活的运动计划(N2)，并更新新的运动计划(P3)。这些额外的处理资源和对瓦楞纸机的更快控制可能反映了在显示威胁方面快速和准确的需求。
We investigated the motor planning and reprogramming of facial expressions of happiness and anger with a response-priming task. A response signal commanded the production of a validly or invalidly cued facial expression. Electromyogram showed performance costs of inhibiting the falsely prepared expression and reprogramming the correct one in invalid trials. These performance costs were larger in zygomaticus major than corrugator supercilii, indicating better control over the latter. Event-related potentials indicated no emotion specificity in the initial preparation of anger and happiness in the contingent negative variation. During reprogramming, anger came along with greater allocation of processing resources for the inhibition of the preactivated motor plan (N2), and the updating of a new one (P3). These additional processing resources and the faster control over corrugator may reflect the need for being quick and accurate in displaying threat.
