Cognitive theorists propose that attentional biases for threatening information play an important role in the development and maintenance of anxiety disorders. If attentional biases for threat figure in the maintenance of anxiety, then the experimental reduction of the bias for threat (attention training) should reduce anxiety. We randomly assigned 41 spider-fearful individuals to receive either attention training (n=20) or control procedures (n=21). We used a modified dot-probe discrimination paradigm with photographs of spiders and cows to train attention. Training reduced attentional bias for spiders, but only temporarily. Although both groups declined in spider fear and avoidance, reduction in attentional bias did not produce significantly greater symptom reduction in the training group than in the control group. However, reduction in attentional bias predicted reduction in self-reported fear for the training group. The reduction in attentional bias for threat may have been insufficiently robust to produce symptom reduction greater than that produced by exposure to a live spider and spider photographs alone. Alternatively, attention training may be an unsuitable intervention for spider fear.
认知理论家提出,对威胁信息的注意力偏差在焦虑障碍的发展和维持中起着重要作用。如果对威胁的注意力偏差在焦虑的维持中起作用,那么实验性地减少对威胁的偏差(注意力训练)应该会降低焦虑。我们随机分配了 41 名蜘蛛恐惧症患者,分别接受注意力训练(n=20)或对照程序(n=21)。我们使用改良的点探测辨别范式,用蜘蛛和奶牛的照片来训练注意力。训练降低了对蜘蛛的注意力偏差,但只是暂时的。尽管两组的蜘蛛恐惧和回避都有所减少,但训练组的注意力偏差减少并没有比对照组产生更大的症状减轻。然而,注意力偏差的减少预测了训练组自我报告恐惧的减少。对威胁的注意力偏差的减少可能不够稳健,无法产生比单独接触活蜘蛛和蜘蛛照片更大的症状减轻。或者,注意力训练可能不适合蜘蛛恐惧的干预。
