Abstract: 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.

Key words: positive sounds, emotional faces, disengagement bias, positivity
