Depressive disorder is characterized by a polymorphic symptomatology associating emotional, cognitive and behavioral disturbances. One of the most specific symptoms is negative beliefs, called congruent to mood. Despite the importance of these beliefs in the development, the maintenance, and the recurrence of depressive episodes, little is known about the processes underlying the generation of depressive beliefs. In this paper, we detail the link between belief updating mechanisms and the genesis of depressive beliefs. We show how depression alters information processing, generating cognitive immunization when processing positive information, affective updating bias related to the valence of belief and prediction error, and difficultie to disengage from negative information. We suggest that disruption of belief-updating mechanisms forms the basis of belief-mood congruence in depression.
抑郁症的特征是具有多态性症状，伴有情绪、认知和行为障碍。最具特异性的症状之一是消极信念，即与情绪相符的信念。尽管这些信念在抑郁发作的发展、维持和复发中具有重要作用，但对于抑郁信念产生的潜在过程却知之甚少。在本文中，我们详细阐述了信念更新机制与抑郁信念产生之间的联系。我们展示了抑郁症如何改变信息处理过程，在处理积极信息时产生认知免疫，与信念的效价和预测误差相关的情感更新偏差，以及难以从消极信息中脱离出来。我们认为信念更新机制的破坏构成了抑郁症中信念-情绪一致性的基础。
