Abstract

Most people enjoy music and often use music to regulate their emotions. Although pleasure derived from music-listening has been shown to be mediated by dopaminergic signals in the mesolimbic reward network, its relationship with physiology is still poorly understood. Here, we introduced time-warped representational similarity analysis (twRSA) to directly map dynamic representations of multiple modalities across variable-duration stimuli. Our method revealed that although time-varying spectral and tonal acoustic features predicted changes in autonomic neural responses (measured via cardiac, pupil, and respiratory activity) during music-listening, only a small subset was in fact relevant to listeners’ on-line pleasure ratings. Despite that, we identified a weak mediation effect of physiology on shaping musical pleasure. Our results thus indicate that whilst musical pleasure may be embodied in bodily responses, the mapping between subjective experience and physiology is likely one-to-many—in line with psychological construction theories of emotion—and not one-to-one as is commonly assumed in classical basic emotion theories.
