情绪信息的快速处理可以适应地调节注意力的分配，但也可能使资源从注意力表现中转移，尤其是对于那些表现出焦虑症的人而言。然而，快速情感处理的时间组织及其对注意力表现的影响尚不清楚。参与者是有18名健康成年人（12名女性），他们报告了特质焦虑症。在每次试验中，提出了50毫秒的恐惧，悲伤和中性的恐惧，悲伤和中立，在每次试验中进行了提示注意任务，以测量警报，定向和执行注意力。脑电图记录是由64个头皮电极制作的，以产生与面部的事件相关电位（ER-PS）。情绪的脸型和特质焦虑调节了在200英寸，250毫秒和320 ms的三个早期阶段的ERP反应。尽管在表现出恐惧和悲伤的面孔后，行为发现表现出了增强的定向和执行注意力，但这些面孔调节了ERP的反应，尤其是250毫秒左右，干扰了高性状焦虑群体的定向和执行注意力，并增强了警觉低性状焦虑群。在情绪捕捉注意力和对理解焦虑中注意过程的影响中的机制中讨论了结果。 （c）2007 Elsevier B.V.保留所有权利。
The rapid processing of emotional information adaptively regulates the allocation of attention, but may also divert resources away from attention performance, particularly for those showing elevated anxiety. The temporal organization of rapid emotional processing and its implications for attention performance, however, remain unclear. Participants were 18 healthy adults (12 females) who reported on trait anxiety. Tasks-irrelevant fearful, sad, and neutral, faces were presented for 50 ms prior to each trial of a cued attention task measuring alerting, orienting, and executive attention. Electroencephalographic recordings were made from 64 scalp electrodes to generate event-related potentials (ER-Ps) to faces. Emotional face type and trait anxiety modulated ERP responses at three early stages around 200 ins, 250 ms, and 320 ms. Although behavioral findings showed enhanced orienting and executive attention following presentation of fearful and sad faces, the degree to which these faces modulated ERP responses, particularly around 250 ms, interfered with orienting and executive attention in the high trait anxiety group, and enhanced alerting in the low trait anxiety group. Results are discussed in terms of mechanisms in the emotional capture of attention and implications for understanding attentional processes in anxiety. (C) 2007 Elsevier B.V. All rights reserved.
