To evaluate whether there is an early attentional bias towards negative stimuli, we tracked participants' eyes while they passively viewed displays composed of four Ekman faces. In Experiment 1 each display consisted of three neutral faces and one face depicting fear or happiness. In half of the trials, all faces were inverted. Although the passive viewing task should have been very sensitive to attentional biases, we found no evidence that overt attention was biased towards fearful faces. Instead, people tended to actively avoid looking at the fearful face. This avoidance was evident very early in scene viewing, suggesting that the threat associated with the faces was evaluated rapidly. Experiment 2 replicated this effect and extended it to angry faces. In sum, our data suggest that negative facial expressions are rapidly analysed and influence visual scanning, but, rather than attract attention, such faces are actively avoided.
为了评估是否存在对负面刺激的早期注意力偏向,我们在参与者被动观看由四张埃克曼面部表情组成的展示时跟踪他们的眼睛。在实验1中,每个展示由三张中性面部表情和一张描绘恐惧或快乐的面部表情组成。在一半的试验中,所有面部表情都是倒置的。尽管被动观看任务应该对注意力偏向非常敏感,但我们没有发现明显的注意力偏向恐惧面部表情的证据。相反,人们倾向于主动避免看向恐惧的面部表情。这种回避在场景观看的早期就很明显,表明与这些面部表情相关的威胁被迅速评估。实验2重复了这一效应,并将其扩展到愤怒的面部表情。总之,我们的数据表明,负面面部表情会被迅速分析并影响视觉扫描,但这些面部表情非但不会吸引注意力,反而会被主动回避。
