Slowed color naming of threat-related words on the modified Stroop task has been interpreted as indicative of selective processing biases, although alternative models have been proposed to explain inconsistent findings. The present study compared the performance of participants with obsessive-compulsive disorder (OCD) and normal controls on a computerized version of the modified Stroop, and investigated the relationship of Stroop effects to avoidant cognitive strategies. Contrary to predictions, control and OCD groups were notably faster at color naming OCD threat, general threat, and positive words compared to neutral words at the strategic level of awareness. This was not the case for OCD threat words at the automatic level of awareness where faster color naming was observed, although the expected differences between groups were not found. A thought replacement measure was generally predictive of OCD participants' automatic pattern of interference for negatively valenced words. Results indicate the complexity of the Stroop effect and the need for its ongoing review.
在改良版斯特鲁普任务中，对与威胁相关词汇的颜色命名速度减慢被解释为选择性加工偏差的表现，不过也有人提出了其他模型来解释不一致的研究结果。本研究比较了强迫症（OCD）患者和正常对照组在计算机化改良版斯特鲁普任务中的表现，并探究了斯特鲁普效应与回避性认知策略之间的关系。与预测相反，在策略性意识水平上，对照组和强迫症组在对强迫症威胁、一般威胁及积极词汇进行颜色命名时，相比中性词汇显著更快。在自动意识水平上，对强迫症威胁词汇进行颜色命名时观察到更快的速度，情况并非如此，尽管未发现两组之间的预期差异。思维替换测量通常能预测强迫症患者对负性情绪词汇的自动干扰模式。结果表明斯特鲁普效应的复杂性以及对其持续审视的必要性。
