Abstract:
The failure of emotional processing in patients with depression is one of the main factors leading to depression. The mechanism of emotional processing failure can be explained by three models of emotional processing theory. The three models are depression cognitive model, situational sensitivity retardation model and cognitive control impaired model. A large number of behavioral, electrophysiological and brain imaging studies have proved the explanation of these three models for depression from various aspects. And based on this perspective, attention bias correction, cognitive behavioral therapy and drug herapy are provided to intervene and treat depression. At present, there are some problems to be solved in this field, such as unclear relationship between models, unclear relationship between negative enhancement effects of various cognitive links, uncle ar pathogenesis of depression and so on, which can be the research direction of future researchers.
抑郁患者的情绪加工过程失效是导致抑郁的一个主要因素,对于患者情绪加工失效的机制可从情绪加工理论的三种模型来解释,这三种模型分别为抑郁认知模型、情境敏感性迟钝模型和认知控制受损模型。大量行为学、电生理学以及脑成像学的研究都从各个方面证明了这三种模型对抑郁发生的解释,并基于此视角,提供注意偏向矫正法、认知行为疗法和药物疗法来对抑郁症进行干预治疗。目前此领域存在各模型间的关系不明确、各认知环节的负性增强效应间的联系不明确、抑郁症的发病机理不明确等有待解决的问题,这可以是未来研究者的研究方向。
