背景。抑郁症患者与健康人在利用新的积极信息调整消极预期的程度上有所不同。在本研究中，我们检验了两组人在接收到意外的消极信息后更新积极预期方面是否也存在差异。
方法：对76名有抑郁症状的人和81名健康对照者进行研究，我们使用了一个先前经过验证的范式的改编版本。在最初建立积极的表现预期之后，参与者进行TEMINT表现测试，随后一半的参与者收到证实先前积极预期的标准化反馈，而另一半则收到否定性的消极反馈。接着，再次评估参与者的表现预期。此外，我们还评估了参与者对反馈的评价，特别是他们是否倾向于忽视反馈。
结果：结果表明，健康受试者总体上比有抑郁症状的人有更积极的预期，但两组在更新预期方面没有差异：两组在收到消极反馈后都朝着消极方向改变了预期；同样，在收到证实性的积极反馈后，两组之间也没有差异。有抑郁症状和无抑郁症状的人如果收到的反馈是消极的，都更有可能忽视该反馈，并且这种对反馈的消极评价与较小的预期更新相关。
结论：结合先前的研究，目前的发现表明，有抑郁症状的人不会对意外的消极信息过度敏感反应；相反，正如先前所示，抑郁症的主要问题似乎是对新的积极信息的整合。
Background. People with depression differ from healthy people in the extent to which they use novel positive information to adjust negative expectations. In this study, we examined whether the two groups also differ in updating positive expectations after receiving unexpectedly negative information.Methods: Examining 76 people with depressive symptoms and 81 healthy controls, we used an adapted version of a previously validated paradigm. After the initial establishment of positive performance expectations, participants worked on the TEMINT performance test, whereupon half of the participants received standardized feedback that confirmed previous positive expectations while the other half received disconfirming negative feedback. Subsequently, participants' performance expectations were assessed again. Additionally, we assessed participants' appraisal of the feedback, particularly whether they tended to disregard it.Results: Results indicated that healthy subjects had overall more positive expectations than people with depressive symptoms, but the two samples did not differ in updating their expectations: both groups changed their expectations in a negative direction after receiving negative feedback; similarly, there were no differences between the two samples after receiving confirmatory positive feedback. Both people with and without depressive symptoms were more likely to disregard the feedback received if the feedback was negative, and such a negative appraisal of the feedback was associated with smaller expectation update.Conclusions: In combination with prior work, the current findings suggest that people with depressive symptoms do not over-sensitively react to unexpectedly negative information; rather, the main problem of depression seems to be the integration of novel positive information, as shown previously.
