The current study explored the proposition that anxiety is associated with impaired inhibition of threat. Using a modified version of the remote distractor paradigm, we considered whether this impairment is related to attentional capture by threat, difficulties disengaging from threat presented within foveal vision, or difficulties orienting to task-relevant stimuli when threat is present in central, parafoveal and peripheral locations in the visual field. Participants were asked to direct their eyes towards and identify a target in the presence and absence of a distractor (an angry, happy or neutral face). Trait anxiety was associated with a delay in initiating eye movements to the target in the presence of central, parafoveal and peripheral threatening distractors. These findings suggest that elevated anxiety is linked to difficulties inhibiting task-irrelevant threat presented across a broad region of the visual field.
本研究探讨了焦虑与威胁抑制受损有关的假设。使用改良的远程干扰范式，我们考虑了这种损害是否与威胁引起的注意力捕获、在中央、旁中央和外周视野中出现威胁时从中央注视视野中呈现的威胁中难以解脱、或难以朝向与任务相关的刺激有关。参与者被要求在有和没有干扰物（愤怒、快乐或中性面孔）的情况下将眼睛转向并识别目标。特质焦虑与在中央、旁中央和外周威胁性干扰物存在的情况下，眼睛向目标移动的延迟有关。这些发现表明，焦虑水平升高与在广阔的视野区域呈现的抑制无关的任务威胁有关。
