患有创伤后应激障碍（PTSD）的创伤受害者可能会将模糊的信息解读为威胁，并且很难抑制这些信息。为了检验这些假设，我们在患有和不患有 PTSD 的受创伤个体中使用了 Gernsbacher、Varner 和 Faust 的同形异义范式的修改版（M. A. Gernsbacher、K. R. Varner 和 M. E. Faust，1990）。我们假设患有 PTSD 可能与同形异义词（具有两种含义的单词，例如，杯子）的威胁相关含义的抑制不良有关。与这一假设一致，我们的结果表明，与没有 PTSD 的受创伤个体相比，患有 PTSD 的受创伤个体对同形异义词的威胁含义的抑制程度较低。这些发现与 PTSD 信息处理偏差的延迟激活模型一致。
Trauma victims with posttraumatic stress disorder (PTSD) may interpret ambiguous information as threatening and have difficulties inhibiting this information. To test these hypotheses, we used a modification of Gernsbacher, Varner, and Faust's homograph paradigm in traumatized individuals with and without PTSD (M. A. Gernsbacher, K. R. Varner, & M. E. Faust, 1990). We hypothesized that having PTSD would be related to poor inhibition of the threat-relevant meanings of homographs (words with two meanings, e. g., mug). Consistent with this hypothesis, our results revealed that traumatized individuals with PTSD showed less inhibition of the threat meanings of homographs than did traumatized individuals without PTSD. These findings are consistent with a delayed activation model of information processing bias in PTSD.
