注意偏误被认为是焦虑的病因和维持因素。然而，建立这种因果关系的经验证据很少，而且只在成人中提供。在这项初步研究中，我们测试了注意偏差的诱导是否会导致报告正常焦虑水平的儿童对压力的脆弱性发生变化。26名7-12岁的儿童被随机分为两组。一组被暴露在一个训练条件下，旨在诱导注意力偏向于远离威胁。另一组则暴露在一个旨在诱导对威胁的注意偏向的训练条件下。接受过应对威胁训练的儿童对与威胁相关的信息提高了注意力警惕性。训练程序对那些被训练以避免威胁的儿童是无效的，他们的注意力仍然是公正的。两个训练组的孩子在压力诱导后都报告抑郁得分升高。然而，只有那些接受过威胁训练的孩子随后报告了焦虑程度的上升。研究结果表明，儿童对威胁的偏向性注意力反应会对面对压力时的焦虑倾向产生特定的影响。(c) 2008 Elsevier Ltd.版权所有。
Attention bias has been suggested as an etiological and maintaining factor in anxiety. However, empirical evidence establishing this causal association is scarce and has been provided only in adults. In this preliminary study, we tested whether an induction of attentional bias can cause changes in vulnerability to stress in children reporting normal anxiety levels. Twenty-six 7-12 year-old children were randomly assigned to two groups. One group was exposed to a training condition designed to induce an attentional bias away from threat. The other group was exposed to a training condition designed to induce an attentional bias toward threat. Children who were trained to attend to threat developed attentional vigilance to threat-related information. The training procedure was ineffective with children who were trained to avoid threat, and their attention remained unbiased. Children from both training groups reported elevated depression scores following stress-induction. However, only the children who were trained to attend to threat subsequently reported elevations in anxiety. The findings suggest that biased attentional responses to threat, among children, can exert a specific influence on the tendency to experience anxiety in the face of stress. (c) 2008 Elsevier Ltd.
