Cognitive theories of anxiety psychopathology cite biased attention towards threat as a central vulnerability and maintaining factor. However, many studies have found threat bias indices to have poor reliability and have failed to observe the theorized relationship between threat bias and anxiety symptoms; this may be due to the non-unitary nature of threat bias and the influence of state-level variables on its expression. Accumulating data suggests that state anxious mood is important for the robust expression of threat bias and for relations to emerge between threat bias and symptoms, though this possibility has not been experimentally tested. Eye-tracking was used to assess multiple forms of threat bias (i.e., early vigilance, sustained attention, facilitated engagement, delayed disengagement) thought to be related to anxiety. A non-clinical sample (N = 165) was recruited to test the hypothesis that biased attention towards threat, but not dysphoric or positive emotional stimuli, during an anxious mood induction, but not at a pre-stress baseline, would prospectively predict greater worry symptoms on days in which more naturalistic stressors occurred. Results revealed the hypothesized moderation effect for sustained attention towards threat after the mood induction but not at baseline, though sustained attention towards dysphoric stimuli also moderated the effect of stressors on worry. Worry-relevant sustained attention towards negative emotional stimuli may be a partially mood-context dependent phenomenon.
焦虑心理病理学的认知理论认为,对威胁的偏向性注意是一个核心的易感性因素和维持因素。然而,许多研究发现威胁偏向指数的可靠性较差,并且未能观察到理论上所认为的威胁偏向与焦虑症状之间的关系;这可能是由于威胁偏向的非单一性质以及状态水平变量对其表现的影响。越来越多的数据表明,状态焦虑情绪对于威胁偏向的强烈表现以及威胁偏向与症状之间关系的出现很重要,尽管这种可能性尚未经过实验验证。眼动追踪被用于评估被认为与焦虑相关的多种形式的威胁偏向(即早期警觉、持续注意、促进参与、延迟脱离)。招募了一个非临床样本(N = 165)来检验以下假设:在诱发焦虑情绪期间而非应激前基线时,对威胁而非烦躁或积极情绪刺激的偏向性注意将前瞻性地预测在出现更多自然主义应激源的日子里会有更严重的担忧症状。结果显示,在情绪诱发后但不是在基线时,对威胁的持续注意存在假设中的调节效应,尽管对烦躁刺激的持续注意也调节了应激源对担忧的影响。与担忧相关的对负面情绪刺激的持续注意可能是一种部分依赖情绪背景的现象。
