焦虑心理病理学的认知理论将对威胁的偏见视为核心脆弱性和维持因素。然而，许多研究发现威胁偏见指标的可靠性较差，并且未能观察到威胁偏见与焦虑症状之间的理论关系;这可能是由于威胁偏见的非单一性以及状态变量对其表达的影响。积累的数据表明，状态焦虑情绪是重要的强大的威胁偏见的表达和威胁偏见和症状之间出现的关系，虽然这种可能性还没有经过实验测试。眼动追踪被用来评估多种形式的威胁偏见（即，早期警惕，持续关注，促进参与，延迟脱离）被认为与焦虑有关。招募了一个非临床样本（N = 165）来检验这一假设，即在焦虑情绪诱导期间，而不是在预压力基线时，将注意力偏向威胁，而不是烦躁或积极的情绪刺激，这将前瞻性地预测更自然的压力源发生的日子里更大的担忧症状。结果显示，假设的温和效应，持续关注的情绪诱导后，对威胁，但不是在基线，虽然持续关注焦虑刺激也缓和的压力源的影响担心。对负面情绪刺激的忧虑相关持续注意可能是一种部分情绪-情境依赖现象。
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.
