The present study aimed to clarify: 1) the presence of depression-related attention bias related to a social stressor, 2) its association with depression-related attention biases as measured under standard conditions, and 3) their association with impaired stress recovery in depression. A sample of 39 participants reporting a broad range of depression levels completed a standard eye-tracking paradigm in which they had to engage/disengage their gaze with/from emotional faces. Participants then underwent a stress induction (i.e., giving a speech), in which their eye movements to false emotional feedback were measured, and stress reactivity and recovery were assessed. Depression level was associated with longer times to engage/disengage attention with/from negative faces under standard conditions and with sustained attention to negative feedback during the speech. These depression-related biases were associated and mediated the association between depression level and self-reported stress recovery, predicting lower recovery from stress after giving the speech.
1)与社会应激源相关的抑郁相关注意偏向的存在;2)其与标准条件下所测量的抑郁相关注意偏向的关联;3)它们与抑郁症中应激恢复受损的关联。39名报告了广泛抑郁水平的参与者完成了一项标准的眼动追踪范式,在此范式中,他们必须注视/移开对情绪面孔的目光。参与者随后接受了一次应激诱导(即发表演讲),在此过程中测量他们对虚假情绪反馈的眼动,并评估应激反应性和恢复情况。抑郁水平与在标准条件下注视/移开负面面孔的时间更长以及在演讲过程中持续关注负面反馈有关。这些与抑郁相关的偏向相互关联,并介导了抑郁水平与自我报告的应激恢复之间的关联,预测了演讲后应激恢复较低。
