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.
本研究考察了在强迫症（OCD）中常见的污染恐惧注意力偏见在多大程度上特定于厌恶或恐惧线索，以及涉及的注意力成分。眼动追踪技术比传统的注意力反应时测量方法提供了更高的敏感性和特异性。参与者根据污染恐惧程度高低（HCF，n=23；LCF，n=25），接受 3 秒试验，观看配对呈现的带有中性面孔的厌恶面孔、恐惧面孔或开心面孔。结果发现，威胁存在警觉和维持偏见的证据。与低恐惧组相比，高恐惧组将注意力集中在恐惧面孔上，而不是厌恶面孔上。然而，与低恐惧组相比，高恐惧组在 3 秒试验中都保持对厌恶和恐惧表情的注意力，这一模式贯穿始终。这些发现对概念化调节污染性 OCD 中注意力偏见的情绪因素具有重要意义。
