Cognitive theories of depression assume biased attention towards mood-congruent information as a central vulnerability and maintaining factor. Among other symptoms, depression is characterized by excessive negative affect (NA). Yet, little is known about the impact of naturally occurring NA on the allocation of attention to emotional information. The study investigates how implicit and explicit NA as well as self-reported depressive symptoms predict attentional biases in a sample of healthy individuals (N = 104). Attentional biases were assessed using eye-tracking during a free viewing task in which images of sad, angry, happy and neutral faces were shown simultaneously. Participants' implicit affectivity was measured indirectly using the Implicit Positive and Negative Affect Test. Questionnaires were administered to assess actual and habitual explicit NA and presence of depressive symptoms. Higher levels of depressive symptoms were associated with sustained attention to sad faces and reduced attention to happy faces. Implicit but not explicit NA significantly predicted gaze behavior towards sad faces independently from depressive symptoms. The present study supports the idea that naturally occurring implicit NA is associated with attention allocation to dysphoric facial expression. The findings demonstrate the utility of implicit affectivity measures in studying individual differences in depression-relevant attentional biases and cognitive vulnerability.
抑郁的认知理论假设,对与情绪一致的信息的偏向性注意是一个核心的脆弱性和维持因素。除了其他症状外,抑郁的特征还包括过度的消极情绪(NA)。然而,人们对自然产生的 NA 对情绪信息注意力分配的影响知之甚少。本研究调查了在健康个体样本中,内隐和外显的 NA 以及自我报告的抑郁症状如何预测注意力偏向(N=104)。在自由观看任务中使用眼动追踪评估注意力偏向,同时显示悲伤、愤怒、快乐和中性面孔的图像。参与者的内隐情感通过内隐正负面情感测试间接测量。通过问卷调查评估实际和习惯性的外显 NA 和抑郁症状的存在。较高的抑郁症状与对悲伤面孔的持续注意力和对快乐面孔的注意力减少有关。内隐但不是外显的 NA 显著预测了对悲伤面孔的注视行为,与抑郁症状无关。本研究支持这样一种观点,即自然产生的内隐 NA 与对不愉快面部表情的注意力分配有关。研究结果表明,内隐情感测量在研究与抑郁相关的注意力偏向和认知脆弱性的个体差异方面具有实用性。
