Prior information can alter how sounds are perceived and emotionally regulated.

Abstract

In the current study, we provided participants with written information about emotional dimensions of a sound presented as a task-irrelevant sound in the context of a serial recall task. We were interested in whether this manipulation would influence sound perception and spontaneous use of emotion regulation strategies. Participants were informed that they would hear either an aversive and annoying sound, or a pleasant and calming sound. They subsequently performed three blocks of a serial recall task with the sound presented in the background and rated the sound after each block. Results showed that participants in the negative information group rated the sound as more negative, with effects diminishing over repeated trials. While not impacting emotion regulation strategy directly, the manipulation indirectly influenced the degree to which participants used mental suppression as a regulatory strategy via changing affective responses. In the negative information condition specifically, participants who experienced the sound as more negative were more inclined to use mental suppression to deal with the sound, whereas no such relationship was observed in the positive information condition. The study adds to our understanding of how sounds come to acquire emotional meaning and how individuals spontaneously cope with emotional, task-irrelevant sounds.
