摘　　要：考察正性声音的注意加工对情绪面孔注意偏向的改变,及个体特质(积极倾向)在这一过程中的调节作用。采用听觉版点探测范式呈现声音刺激,靶声音总是与正性声音同耳播放,使得实验组被试总是加工正性听觉刺激,采用点探测范式测量被试对情绪面孔的注意偏向及其改变。结果发现,实验组对负性情绪面孔的解除困难显著减少,个体的积极倾向在负解除困难的改变中起调节作用,低积极倾向个体的改变更为显著。研究表明对正性声音的注意加工能够跨通道影响对情绪面孔的注意偏向,个体特征会调节注意偏向的改变,表明注意偏向的跨通道可塑性。The aim of this research was to investigate how attentional biases towards emotional faces were impacted by attentional processing to auditory stimuli.There were sixty-seven college students recruited in this research and were randomly assigned to complete a computerized task designed to induce selective processing of positive sounds or to a sham condition with auditory adaption of dot-probe paradigm.The attentional biases to emotional faces were measured twice before and after the task with dot-probe paradigm.Our results revealed that participants who completed the computerized task showed more reduction of disengagement bias to angry faces compared to that in sham condition.What s more,participants in the two groups didn t show different motion change in the whole experiment.We also measured individual s positivity and found that individual s positivity played a moderating role in attentional bias change.People with lower-level positivity obtained more reduction of disengagement bias toward angry faces.Our results support that attentional bias towards visual stimuli could be changed by processing of positive auditory stimuli,which showing great malleability,and is influenced by individual characteristics.
