The present study aims to investigate whether it is possible to indetifiy distinctive acoustic breathing patterns related to different emotional conditions (anger, fear, sadness, disgust, joy and tenderness) and to investigate how "breathing together" influences the attunement process between participants, considering different dimensions: emotional decoding, similarity of the emotional experiences, perspective taking and interpersonal synchrony. In particular we hypothesize that the more synchronized the imitation of the partner’s breathing, the more accurate the understanding of his emotional experience.
