Event-Related Potentials Reflect the Affective Priming Capacity of Music on Speech

Abstract

<p>Music, like language, is a universal means of communication unique to humans, and the overlap of music and linguistic cognitive and neurological processes is well established. Performers and listeners alike are drawn to music as an avenue of emotional expression, as music is recognized for its rich emotional content. The study of affective priming indicates the communication of emotion-based concepts: stimuli that are related by affect give rise to response facilitation, an effect not observed to stimuli that are unrelated by affect. The measure of event-related brain potentials (ERPs) reveal, with exquisite temporal accuracy, that music clearly conveys emotion concepts in a manner commensurate to written language and prosody. To date, ERP studies of affective priming with music have involved written language and prosody, and have focused on the N400, an indication of semantic cognitive integration. The current study is the first to measure ERP responses in an affective priming paradigm of music and speech. In addition to the N400, the current study is the first of its kind to measure the N300, indicating cognitive categorization and the P300, reflecting recognition. Three sets of analyses – based on categorically correct responses, behaviourally correct responses and subjective responses – reveal N300 and N400 affective priming effects, corresponding to deliberate cognitive categorization and conceptual integration, respectively.</p>
