Decades of research has shown the influence of emotion on attentional capture, and more recently, the influence of emotion on neurophysiological processes related to attentional capture. The current research tested whether some of the earliest neurophysiological underpinnings of emotive attentional processes can be influenced by attentional manipulations of broadening versus narrowing. Previous research has shown that negative affects high in motivational intensity (e.g., disgust, fear) cause a relative narrowing of attentional scope (Gable and Harmon-Jones, 2010a; Easterbrook, 1959). Because of the strong link between motivation and attention, attentional scope should also influence the attentional capture of negative stimuli. The current study manipulated a local attentional scope or global attentional scope, then measured attentional capture towards disgust and neutral pictures using the N1 event-related potential component. Results revealed that a manipulated global attentional scope reduced N1 amplitude towards disgust pictures compared to a manipulated local attentional scope.
数十年的研究表明,情绪会影响注意力的捕捉,最近的研究还表明,情绪会影响与注意力捕捉相关的神经生理过程。本研究测试了情感注意过程的一些最早的神经生理基础是否可以通过拓宽与收窄注意力的注意力操作来影响。先前的研究表明,动机强度高的负性情绪(例如,厌恶、恐惧)会导致注意力范围相对缩小(Gable 和 Harmon-Jones,2010a;Easterbrook,1959)。由于动机和注意力之间有着很强的联系,注意力范围也应该会影响到对负性刺激的注意力捕捉。本研究通过局部注意力范围或全局注意力范围的操作,然后使用 N1 事件相关电位成分测量对厌恶和中性图片的注意力捕捉。结果表明,与局部注意力范围操作相比,全局注意力范围的操作会降低对厌恶图片的 N1 振幅。
