Previous research using attentional search tasks has revealed an anxiety-related bias favouring attention to threatening words when they are presented simultaneously with emotionally neutral words. In Experiment 1, using a similar task, a related effect was found here with emotionally threatening pictures. When pictures were used as location cues in a second experiment, high-trait anxious individuals were slower than less anxious controls when responding to targets requiring attentional disengagement from threat, and they were slower in general with pictures judged to be highly threatening. In a third experiment using the same task but with a longer cue exposure, a related disengagement difficulty occurred across both groups, although the more general slowing with severe threat was again confined to the anxious group. We conclude that attentional bias involves both a specific difficulty in disengaging attention from the location of any threat and a more general interference effect that is related to threat level.
以往使用注意力搜索任务的研究表明,当威胁性词语与情绪中性词语同时出现时,存在一种与焦虑相关的偏向,即更倾向于关注威胁性词语。在实验1中,使用类似任务,在此发现了情绪威胁性图片的相关效应。在第二个实验中,当图片用作位置线索时,高特质焦虑个体在对需要从威胁中脱离注意力的目标做出反应时,比低焦虑对照组更慢,而且他们对被判定为高度威胁性的图片总体反应更慢。在第三个实验中,使用相同任务但线索呈现时间更长,两组都出现了相关的脱离困难,尽管严重威胁导致的更普遍的反应迟缓再次仅限于焦虑组。我们得出结论,注意力偏向既涉及从任何威胁位置脱离注意力的特定困难,也涉及与威胁水平相关的更普遍的干扰效应。
