Whereas the association between depression and the perception of emotions has been widely studied, only few studies have examined the association between depression and the ability to discriminate genuine (Duchenne) from fake (non-Duchenne) smiles. The present study examined this by comparing currently depressed, previously depressed, and healthy control individuals. Guided by recent theory, the present study also investigated the effect of depression recurrence on smile identification.
Participants were 27 healthy controls, 33 with past depression (51% with recurrent depression), and 22 with current depression (77% with recurrent depression). Participants were presented with a series of 20 videos depicting smiling individuals, and were asked to indicate whether each smile was genuine or fake.
Having (or having had) a first episode of depression was associated with more mistakes in categorizing smiles as genuine or fake compared to having recurrent depression or to having no history of depression.
Cross sectional design and a (relatively) small sample size.
Our results show that an impaired ability to differentiate between markers of affiliation and politeness is specific to first-episode depression, even after the depression has remitted.
尽管抑郁与情绪感知之间的关联已得到广泛研究，但仅有少数研究考察了抑郁与区分真实（杜兴氏）微笑和虚假（非杜兴氏）微笑能力之间的关联。本研究通过比较当前抑郁、既往抑郁和健康对照个体来对此进行研究。在近期理论的指导下，本研究还调查了抑郁复发对微笑识别的影响。
参与者包括27名健康对照者、33名既往有抑郁史者（51%有复发性抑郁）以及22名当前抑郁者（77%有复发性抑郁）。向参与者展示一系列20个描绘微笑个体的视频，并要求他们指出每个微笑是真实的还是虚假的。
与有复发性抑郁或无抑郁病史相比，首次发作抑郁（或曾有过首次发作抑郁）与在将微笑分类为真实或虚假时出现更多错误有关。
横断面设计以及（相对）较小的样本量。
我们的结果表明，区分亲和与礼貌标志的能力受损是首次发作抑郁所特有的，即使在抑郁缓解之后也是如此。
