使用视觉搜索方法，我们研究了害怕的动物刺激对注意力的影响。我们的结果证实了情绪对注意力的重要作用。所有参与者在水果背景下检测到与恐惧相关的刺激（蛇和蜘蛛）都比中性刺激（蘑菇）更快。此外，与恐惧相关但不害怕的刺激（蛇）和中性刺激相比，害怕蜘蛛的参与者特别敏感地检测他们害怕的刺激（蜘蛛）。然而，对于害怕蛇的参与者来说，害怕的（蛇）和与恐惧相关但不害怕的动物刺激（蜘蛛）之间的检测潜伏期没有显着差异。注意力任务的结果反映在情绪评级中，这表明蜘蛛恐惧是高度具体的，而蛇恐惧与对所有负面刺激的更普遍的增强评估相关。 (C) 2009 Elsevier Ltd，保留所有权利，
Using a visual search methodology we investigated the effect of feared animal stimuli on attention. Our results confirmed the important role of emotion on attention. All participants detected fear-relevant stimuli (snakes and spiders) faster than neutral (mushrooms) ones against a background of fruits. In addition, spider fearful participants were sensitized specifically to detect their feared stimulus (spiders), compared to their fear-relevant but non-feared (snakes) and neutral stimuli. However, for participants fearful of snakes there was no significant difference in detection latencies between the feared (snakes) and the fear-relevant but non-feared animal stimuli (spiders). The results from the attention task were mirrored in the emotional ratings, which showed that spider fear was highly specific, whereas snake fear was associated with a more generalized enhanced evaluation of all negative stimuli.
