本研究考察了预期焦虑与选择性情绪加工的相互作用。为了达到这个目的，一系列令人愉快的、中性的和令人不快的图片被交替地呈现在震惊或安全威胁的区块中，这些区块由彩色图片框架表示。主要发现是，愉快的图片引起了持续的负差异电位在枕区的威胁相比，安全期。与此相反，不愉快和中性的图片处理没有变化的功能，休克的威胁。此外，在安全和休克威胁条件下，情绪图片引起了扩大的早期后负性和晚期正电位。这些数据表明，激活的恐惧/焦虑网络施加特定的影响价的情感图片处理。与当前预期焦虑状态不匹配的愉快刺激显然会吸引更多的注意资源。
The present study examined the interaction of anticipatory anxiety and selective emotion processing. Toward this end, a rapid stream of pleasant, neutral, and unpleasant pictures was presented in alternating blocks of threat-of-shock or safety, which were signaled by colored picture frames. The main finding is that pleasant pictures elicited a sustained negative difference potential over occipital regions during threat as compared to safety periods. In contrast, unpleasant and neutral picture processing did not vary as a function of threat-of-shock. Furthermore, in both the safety and threat-of-shock conditions, emotional pictures elicited an enlarged early posterior negativity and late positive potential. These data show that the activation of the fear/anxiety network exerts valence-specific effects on affective picture processing. Pleasant stimuli mismatching the current state of anticipatory anxiety apparently draw more attentional resources.
