本研究采用一种包含语义操作的改良Stroop任务来研究强迫症患者对恐惧相关信息的加工。23个有洗涤仪式的业主立案法团（洗衣机），10个没有洗涤仪式的业主立案法团（nonwashers），和14个正常人进行了修改后的Stroop任务，他们被要求以颜色命名污染的话，一般的威胁词，中性词，和nonwords。每个单词之前都有四个随机顺序的启动刺激之一：XXXXX，危险，打扰，水果。OC洗衣机表现出更长的反应延迟污染的话比中性的话。此外，他们对污染词的潜伏期比OC非洗涤者和正常人的潜伏期长，但只有后者的差异达到显著性。OC nonwashers表现出较长的laerance一般威胁词比nonwords和normals的颜色命名中性词比污染或一般威胁词。假设所有的主题将显示效果的启动水果的话的数据支持，较长的颜色命名lasting水果的话之前，总理水果。假设洗衣机将显示更长的时间lasting污染的话，当他们被启动的危险比当他们被启动的非字XXXXX没有得到证实。本文还讨论了与启动操作相关的研究结果的理论意义、改良Stroop效应的特异性及其临床意义
A modified Stroop task incorporating a semantic manipulation was used to study processing of fear-related information in patients diagnosed with obsessive-compulsive disorder (OCD). Twenty-three OCs with washing rituals (washers), 10 OCs without washing rituals (nonwashers), and 14 normals were administered a modified Stroop task in which they were asked to color-name contamination words, general threat words, neutral words, and nonwords. Each word was preceded by one of four priming stimuli in a randomized order; XXXXX, danger, disturb, fruit. OC washers evidenced longer response latencies to contamination words than to neutral words. Also, their latencies to contamination words were longer than the latencies of OC nonwashers and of normals, but only the latter difference reached significance. OC nonwashers evidenced longer latencies to general threat words than to nonwords and normals were slower in color naming neutral words than either contamination or general threat words. The hypothesis that all subjects would show an effect of priming for the fruit words was supported by the data; longer color-naming latencies were found for fruit words when preceded by the prime fruit. The hypothesis that washers would show longer latencies for contamination words when they were primed by danger than when they were primed by the nonword XXXXX was not confirmed. The theoretical implication of the findings related to the priming manipulation, the specificity of the modified Stroop effects, and their clinical relevance are discussed
