作者采用改良的Stroop程序研究了机动车事故幸存者对威胁词的加工。包括三个样本：28名参与者患有创伤后应激障碍（PTSD）和疼痛，26名参与者患有疼痛而没有PTSD，21名参与者没有疼痛或任何精神疾病。使用了四个词类别：（a）事故词，（B）疼痛词，（c）积极词，（d）中性词。本研究探讨了是否会发生加工偏见事故的话，只有在参与者与创伤后应激障碍，或者如果这些偏见也会注意到在没有创伤后应激障碍/疼痛样本。此外，本研究探讨是否加工偏见会注意到疼痛的话，在2个疼痛样本，无论创伤后应激障碍。总体而言，与其他组相比，创伤后应激障碍/疼痛组的颜色命名明显较慢。同样，PTSD/疼痛样本显示出对事故和疼痛相关词语的显著反应延迟，而无PTSD/疼痛的患者仅显示出对疼痛刺激的延迟。
The authors investigated processing of threat words in motor vehicle accident survivors using a modified Stroop procedure. Three samples were included: 28 participants with comorbid posttraumatic stress disorder (PTSD) and pain, 26 participants with pain without PTSD, and 21 participants without pain or any psychiatric conditions. Four word categories were used: (a) accident words, (b) pain words, (c) positive words, and (d) neutral words. This study examined whether processing biases would occur to accident words only in participants with PTSD or if these biases would also be noted in the No PTSD/Pain sample. Additionally, this study examined whether processing biases would be noted to pain words in the 2 pain samples, irrespective of PTSD. Overall, color naming was significantly slower in the PTSD/Pain group in comparison with the other groups. As well, the PTSD/Pain sample showed significant response delays to both accident and pain-related words, whereas patients with No PTSD/Pain showed delays to pain stimuli only.
