大量证据表明，与低特质焦虑个体(LTA)相比，高特质焦虑个体(HTA)对威胁的关注程度更高。在两个实验中，我们调查了这种注意偏差是否与促进对威胁的注意接触或难以将注意力从威胁中分离有关。HTA和LTA的本科生完成了一项改良的外源性线索任务，在这项任务中，目标的位置被中性、高度和轻度威胁的图片正确或错误地提示。结果表明，在100ms的图片呈现下，HTA个体比LTA个体对高威胁性图片的关注程度更高，对高威胁性图片的解脱能力更差。此外，在200和500ms的图片呈现下，HTA个体表现出更强的注意回避威胁倾向。这些数据为在信息加工的早期阶段和后期阶段注意处理威胁时焦虑相关偏向的不同模式提供了证据。(C)2006爱思唯尔有限公司。保留所有权利。
There is a wealth of evidence demonstrating enhanced attention to threat in high trait anxious individuals (HTA) compared with low trait anxious individuals (LTA). In two experiments, we investigated whether this attentional bias is related to facilitated attentional engagement to threat or difficulties disengaging attention from threat. HTA and LTA undergraduates performed a modified exogenous cueing task, in which the location of a target was correctly or incorrectly cued by neutral, highly and mildly threatening pictures. Results indicate that at 100ms picture presentation, HTA individuals more strongly engaged their attention with and showed impaired disengagement from highly threatening pictures than LTA individuals. In addition, HTA individuals showed a stronger tendency to attentional avoidance of threat at the 200 and 500ms picture presentation. These data provide evidence for differential patterns of anxiety-related biases in attentive processing of threat at early versus later stages of information processing. (c) 2006 Elsevier Ltd.
