在有人看管的地方，情绪和注意力相互作用，有利于对比敏感度，一个基本的视觉尺寸。无人值守地点是否有相关费用尚不清楚。此外，情绪和注意力会影响反应时间，而焦虑会调节这些影响。本研究探讨特质焦虑对情绪与注意交互作用对对比敏感度的影响。在每一次试验中，非预测性的precues（中性或恐惧的面孔）将外源性注意力引导到四个对比度变化的倾斜刺激（Gabor贴片）。注意力被指向目标（有效）、分心物（无效）或分布在所有位置。观察者辨别目标取向，并完成自我报告的焦虑措施。恐惧表情的影响由特质焦虑介导。只有高特质焦虑的个人表现出降低目标对比敏感度后，注意力转移到一个分心的可怕的线索，焦虑分数与受损程度的参与者。这表明焦虑的增加加剧了与威胁相关的视觉感知注意力成本，阻碍了非威胁相关位置的处理。
At attended locations emotion and attention interact to benefit contrast sensitivity, a basic visual dimension. Whether there are associated costs at unattended locations is unknown. Furthermore, emotion and attention affect response time, and anxiety modulates these effects. We investigated how trait-anxiety influences the interaction of emotion and attention on contrast sensitivity. On each trial, non-predictive precues (neutral or fearful faces) directed exogenous attention to four contrast-varying, tilted stimuli (Gabor patches). Attention was cued toward the target (valid), a distracter (invalid), or distributed over all locations. Observers discriminated target orientation, and completed self-report measures of anxiety. Effects of fearful expressions were mediated by trait-anxiety. Only high-trait anxious individuals showed decreased target contrast sensitivity after attention was diverted to a distracter by a fearful cue, and anxiety score correlated with degree of impairment across participants. This indicates that increasing anxiety exacerbates threat-related attentional costs to visual perception, hampering processing at non-threat-related locations.
