We studied the effects of negative cognitive style, sad mood, and facial affect on the self-face advantage in a sample of 66 healthy individuals (mean age 26.5 years, range 19-47 years). The sample was subdivided into four groups according to inferential style and responsivity to sad mood induction. Following a sad mood induction, we examined the effect on working memory of an incidental association between facial affect, facial identity, and head-pose orientation. Overall, head-pose recognition was more accurate for the self-face than for nonself face (self-face advantage, SFA). However, participants high in negative cognitive style who experienced higher levels of sadness displayed a stronger SFA for sad expressions than happy expressions. The remaining participants displayed an opposite bias (a stronger SFA for happy expressions than sad expressions), or no bias. These findings highlight the importance of trait-vulnerability status in the working memory biases related to emotional facial expressions.
我们研究了消极认知风格、悲伤情绪和面部表情对 66 名健康个体（平均年龄 26.5 岁，范围 19-47 岁）的自我面孔优势的影响。根据推理风格和对悲伤情绪诱导的反应性，将样本分为四组。在悲伤情绪诱导后，我们研究了面部表情、面部身份和头部姿势方向之间的偶然联想对工作记忆的影响。总的来说，头部姿势识别对于自我面孔比对非自我面孔（自我面孔优势，SFA）更准确。然而，消极认知风格较高且经历较高悲伤水平的参与者对悲伤表情的 SFA 强于对快乐表情的 SFA。其余参与者表现出相反的偏见（对快乐表情的 SFA 强于悲伤表情），或者没有偏见。这些发现强调了特质易损性状态在与情绪面部表情相关的工作记忆偏差中的重要性。
