Major depressive disorder (MDD) is characterized by pervasive mood disturbance as well as deficits in emotional processing, reactivity, and regulation. There is accumulating evidence that MDD is characterized by emotional patterns consistent with environmental disengagement, as reflected in attenuated positive and negative emotional reactivity, consistent with Emotion Context Insensitivity (ECI) theory. However, MDD individuals vary considerably in the extent to which they exhibit specific alterations in patterns of emotional responding. Emotions are complex, multicomponent processes that invoke responses across multiple functional domains and levels of analysis, including subjective experience, behavior, autonomic regulation, cognition, and neural processing. In this article, I review the current state of the literature on emotional responding and MDD from the lens of ECI. I focus on the importance of assessing emotional indices from multiple levels of analysis across development and contexts. I also discuss methodological and measurement issues that may contribute to inconsistent findings. In particular, I emphasize how psychophysiological measures can help elucidate emotional processes that underlie the pathophysiology of MDD as part of an integrated and contextualized approach.
重度抑郁症(MDD)的特征是普遍的情绪障碍,以及在情绪处理、反应和调节方面的缺陷。越来越多的证据表明,MDD 的特征是与环境脱节一致的情绪模式,这反映在减弱的积极和消极情绪反应上,与情绪情境不敏感(ECI)理论一致。然而,MDD 个体在表现出特定的情绪反应模式改变的程度上存在很大差异。情绪是复杂的、多成分的过程,它会在多个功能领域和分析层次上引发反应,包括主观体验、行为、自主调节、认知和神经处理。在本文中,我从 ECI 的角度回顾了关于情绪反应和 MDD 的现有文献。我重点介绍了在发展和背景下从多个分析层次评估情绪指标的重要性。我还讨论了可能导致不一致发现的方法学和测量问题。特别是,我强调了生理心理测量如何有助于阐明 MDD 病理生理学的情绪过程,作为综合和情境化方法的一部分。
