Facial crowds of emotion connoting approval or criticism are linked to the fears of socially anxious individuals. We examined evaluation ratings and decision latencies of mixed facial displays by individuals with generalized social phobia (GSPs, n = 18), individuals with comorbid depression and GSP (COMs, n = 18), and normal controls (CONs, n = 18). First, we postulated that GSPs will assign more negative ratings to predominantly disapproving audiences as compared to CONs, and that GSPs will be faster in their evaluation of these audiences (negative bias hypothesis). Second, we expected depression, but not social anxiety, to be associated with diminished positive evaluation of audiences containing predominantly happy expressions and with a slower processing of such positive cues (the impaired positivity hypothesis). Results supported the negative bias hypothesis, and provided partial support for the impaired positivity hypothesis. The importance of examining the processing of complex non-verbal cues in social anxiety and in depression is discussed.
传达赞成或批评情绪的面部表情群体与社交焦虑个体的恐惧有关。我们研究了广泛性社交恐惧症患者（GSPs，n = 18）、共病抑郁症和GSP的个体（COMs，n = 18）以及正常对照组（CONs，n = 18）对混合面部表情的评价等级和决策潜伏期。首先，我们假设与CONs相比，GSPs会给主要持反对态度的观众赋予更多负面评价，并且GSPs对这些观众的评价会更快（负性偏差假设）。其次，我们预期抑郁症而非社交焦虑会与对主要包含快乐表情的观众的积极评价降低以及对这类积极线索的处理速度减慢有关（积极评价受损假设）。结果支持了负性偏差假设，并为积极评价受损假设提供了部分支持。文中讨论了研究社交焦虑和抑郁症中复杂非言语线索处理的重要性。
