Prior studies on attentional biases in obsessive-compulsive disorder (OCD) have yielded conflicting results. Using a new methodology based on a spatial cueing paradigm, it was investigated whether OCD checkers display heightened vigilance for concern-related material or difficulties disengaging from such stimuli. Twenty-eight OCD patients, 21 of whom were checkers, were compared to 27 controls. In the spatial cueing paradigm task, patients and controls responded to a visual target at one out of two possible locations, which was preceded by a verbal cue word presented at the same or at the opposite location of the target. Cue words were either checking-relevant (e.g., doubt), neutral (e.g., box), or paranoia-related (e.g., spy). No evidence for an attentional bias in OCD checkers was found. This study is in accordance with previous studies, which were unable to detect attentional biases in OCD patients.
先前关于强迫症（OCD）患者注意力偏差的研究结果相互矛盾。本研究采用基于空间线索范式的新方法，探究了OCD检查者是否对与担忧相关的材料表现出更高的警觉性，或者是否难以从这类刺激中脱离注意力。研究将28名OCD患者（其中21名是检查者）与27名对照者进行了比较。在空间线索范式任务中，患者和对照者要对两个可能位置之一出现的视觉目标做出反应，在目标出现之前，会在目标的相同或相反位置呈现一个言语线索词。线索词要么与检查相关（如“怀疑”）、中性（如“盒子”），要么与偏执相关（如“间谍”）。研究未发现OCD检查者存在注意力偏差的证据。本研究与先前无法检测出OCD患者注意力偏差的研究结果一致。
