情感状态影响随后的注意力分配。我们通过重新评估广泛性焦虑症（GAD）患者相对于正常对照的情绪消极偏差调节情况。获得事件相关电位 (ERP) 记录，并在减少负面情绪或建立中性条件后记录对负面或中性词语反应的 P200 和 P300 振幅的变化。我们发现，仅在 GAD 患者中，出现负面词后的平均 P200 幅度远高于出现中性词后。在正常对照中，负面情绪下调后，对负面词的反应的平均 P300 幅度远低于对中性词的反应，这在左右区域都很显着。在GAD患者中，负偏倚仍然突出，并且不受早期重新评估的影响。观察到重新评估在后期具有偏向效应。
Affective states influence subsequent attention allocation. We evaluated emotional negativity bias modulation by reappraisal in patients with generalized anxiety disorder (GAD) relative to normal controls. Event-related potential (ERP) recordings were obtained, and changes in P200 and P300 amplitudes in response to negative or neutral words were noted after decreasing negative emotion or establishing a neutral condition. We found that in GAD patients only, the mean P200 amplitude after negative word presentation was much higher than after the presentation of neutral words. In normal controls, after downregulation of negative emotion, the mean P300 amplitude in response to negative words was much lower than after neutral words, and this was significant in both the left and right regions. In GAD patients, the negative bias remained prominent and was not affected by reappraisal at the early stage. Reappraisal was observed to have a lateralized effect at the late stage.
