先前的研究经常使用点探测任务将焦虑与对威胁的注意力警惕联系起来，该任务在空间位置中呈现探测，这些空间位置之前有或没有假定的威胁刺激。本研究调查的影响，担心的威胁警惕性，通过管理这项任务在担心的条件下，在心算控制条件下，56名本科生得分在低正常范围内的长期担心的措施。担心感应与更快的反应比算术探头在参加的位置以下的威胁词，表明担心和威胁的综合影响，促进注意力。在担心的条件下，在出席的位置探测的反应更快的审判含有威胁词比只有中性词的审判，而匡威的模式观察到在无人值守的位置探测的反应。担心状态和威胁引起的注意力捕获之间的这种联系可能是理解过度警觉对焦虑及其障碍中信息处理的影响的核心。
Prior research has often linked anxiety to attentional vigilance for threat using the dot probe task, which presents probes in spatial locations that were or were not preceded by a putative threat stimulus. The present study investigated the impact of worry on threat vigilance by administering this task during a worry condition and during a mental arithmetic control condition to 56 undergraduate students scoring in the low normal range on a measure of chronic worry. The worry induction was associated with faster responses than arithmetic to probes in the attended location following threat words, indicating the combined influence of worry and threat in facilitating attention. Within the worry condition, responses to probes in the attended location were faster for trials containing threat words than for trials with only neutral words, whereas the converse pattern was observed for responses to probes in the unattended location. This connection between worry states and attentional capture by threat may be central to understanding the impact of hypervigilance on information processing in anxiety and its disorders.
