Growing evidence suggests that generalized anxiety disorder (GAD) is associated with poor affective flexibility, defined as the ability to switch between emotional aspects and non-emotional aspects of a situation. However, it is unclear whether affective inflexibility is valence-specific in GAD. Participants with GAD ( = 21) and non-clinical control participants ( = 28) were tested on an Affective Switching Task during which participants were asked to categorize pictures either by the valence or by the number of humans present in the pictures. Individuals with GAD, but not healthy controls, exhibited greater difficulty shifting from emotional aspects of negative material compared to emotional aspects of positive material and shifting to the emotional aspects of positive material compared to emotional aspects of negative material. These findings suggest that GAD is associated with valence-specific affective flexibility biases. The relevance of the findings and directions for future research are discussed.
越来越多的证据表明,广泛性焦虑障碍(GAD)与不良的情感灵活性有关,情感灵活性定义为在情境的情感方面和非情感方面之间进行切换的能力。然而,GAD 中的情感不灵活性是否具有效价特异性尚不清楚。在情感转换任务中对 GAD 患者( = 21)和非临床对照参与者( = 28)进行了测试,在此任务中,参与者被要求根据图片的效价或图片中出现的人数对图片进行分类。与积极材料的情感方面相比,GAD 患者而非健康对照组在从消极材料的情感方面转换时表现出更大的困难,并且与消极材料的情感方面相比,转换为积极材料的情感方面也更为困难。这些发现表明,GAD 与效价特异性情感灵活性偏见有关。讨论了研究结果的相关性和未来研究方向。
