Using an experimentally based, computer-presented task, this study assessed cognitive inhibition and interference in individuals from the dissociative identity disorder (DID; n=12), generalized anxiety disorder (GAD; n=12) and non-clinical (n=12) populations. Participants were assessed in a neutral and emotionally negative (anxiety provoking) context, manipulated by experimental instructions and word stimuli. The DID sample displayed effective cognitive inhibition in the neutral but not the anxious context. The GAD sample displayed the opposite findings. However, the interaction between group and context failed to reach significance. There was no indication of an attentional bias to non-schema specific negative words in any sample. Results are discussed in terms of the potential benefit of weakened cognitive inhibition during anxious arousal in dissociative individuals.
本研究采用基于实验的计算机呈现任务，评估了分离性身份障碍（DID；n = 12）、广泛性焦虑症（GAD；n = 12）和非临床人群（n = 12）的认知抑制和干扰情况。通过实验指导语和单词刺激，在中性和情绪消极（引发焦虑）的情境下对参与者进行评估。DID样本在中性情境下表现出有效的认知抑制，但在焦虑情境下则不然。GAD样本呈现出相反的结果。然而，组间与情境之间的交互作用未达到显著水平。在任何样本中，均未显示出对非图式特定消极词汇的注意偏向。本文根据分离性个体在焦虑唤起期间认知抑制减弱的潜在益处对研究结果进行了讨论。
