Previous research suggested that individuals with high trait anxiety have difficulties disengaging their attention from threatening cues, whereas those with low trait anxiety have no such attentional bias. However, according to some cognitive models of threat-related attention, low anxious people should show the same pattern as high anxious people when the threat value is large enough. To test this hypothesis, extremely threatening pictures were used as predictive location cues in a cue-target task. Neutral pictures were included as controls. 15 High Anxious participants and 17 Low Anxious participants were selected from 213 volunteers who all were police veterans. Analysis showed that threat cues produced greater facilitation effects than neutral cues, but this was not modulated by anxiety. This suggests that both high and low anxious individuals may have difficulties disengaging their attention from threat-cued locations when the threat value is large enough.
先前的研究表明，特质焦虑水平高的个体难以将注意力从威胁性线索上转移，而特质焦虑水平低的个体则不存在这种注意偏向。然而，根据一些与威胁相关的注意的认知模型，当威胁值足够大时，低焦虑的人应该表现出与高焦虑的人相同的模式。为了验证这一假设，在一个线索-目标任务中，使用极度威胁性的图片作为预测位置线索。中性图片作为对照。从213名均为退伍警察的志愿者中选取了15名高焦虑参与者和17名低焦虑参与者。分析表明，威胁线索比中性线索产生了更大的促进作用，但这并未受到焦虑的调节。这表明，当威胁值足够大时，高焦虑和低焦虑个体都可能难以将注意力从由威胁线索提示的位置上转移。
