本研究考察了强迫症(OCD)中常见的污染恐惧中的注意偏差在多大程度上特定于厌恶或恐惧线索，以及涉及的注意成分。眼球跟踪被用来提供比传统的注意力反应时间测量提供的更高的灵敏度和特异度。在S的3个实验中，被试分别呈现了厌恶、恐惧或高兴的面孔和中性的面孔。发现了对威胁保持警惕和以维护为基础的偏见的证据。与低分组相比，高分组更倾向于关注恐惧的面孔，而不是厌恶的面孔。然而，与低水平组相比，高水平组保持着对厌恶和恐惧表情的关注，这一模式在S的三次试验中都是一致的。这些发现的含义是概念化的情感因素，适度的注意偏差，在污染为基础的强迫症进行了讨论。(C)2010爱思唯尔有限公司。保留所有权利。
The present study examines the extent to which attentional biases in contamination fear commonly observed in obsessive-compulsive disorder (OCD) are specific to disgust or fear cues, as well as the components of attention involved. Eye tracking was used to provide greater sensitivity and specificity than afforded by traditional reaction time measures of attention. Participants high (HCF; n = 23) and low (LCF; n = 25) in contamination fear were presented with disgusted, fearful, or happy faces paired with neutral faces for 3 s trials. Evidence of both vigilance and maintenance-based biases for threat was found. The high group oriented attention to fearful faces but not disgusted faces compared to the low group. However, the high group maintained attention on both disgusted and fearful expressions compared to the low group, a pattern consistent across the 3 s trials. The implications of these findings for conceptualizing emotional factors that moderate attentional biases in contamination-based OCD are discussed. (c) 2010 Elsevier Ltd. All rights reserved.
