60名患有创伤后应激障碍的退伍军人在4种情境条件中完成了一项情绪Stroop任务，旨在测试对注意偏差抑制效应的理论解释。结果显示，当情绪Stroop任务是在未来威胁观看战斗视频或发表演讲的情况下进行时，注意力偏向受到抑制。当应激源内容与Stroop上的单词内容匹配时，抑制效应最强的预测得到的支持有限。与威胁条件下的参与者相比，那些认为他们会因为快速命名颜色而获得额外补偿的退伍军人，或者认为他们不会有其他实验要求的退伍军人，在用颜色命名战斗威胁词时速度较慢。对这些发现可能的理论解释也进行了讨论。
Sixty combat veterans with posttraumatic stress disorder performed an emotional Stroop task under I of 4 contextual conditions designed to test theoretical explanations for an attentional bias suppression effect. Results revealed that when the emotional Stroop task was performed under conditions involving a future threat of either watching a combat video or giving a speech, attentional bias was inhibited. There was limited support for the prediction that the suppression effect was strongest when stressor content matched word content on the Stroop. In contrast to participants in the threat conditions, veterans who believed that they would receive additional compensation for speeded color naming or who believed that they would have no other experimental demands were slower when color naming combat-threat words. Potential theoretical explanations of the findings are discussed.
