Motherese is but one part of a ritualized, multimodal, temporally organized, affiliative interaction

Abstract:

Visual (facial), tactile, and gestural, as well as vocal, elements of mother-infant interactions are each formalizations, repetitions, exaggerations, and elaborations of ordinary adult communicative signals of affiliation – suggesting ritualization. They are temporally organized and enable emotional coordination of the interacting pair. This larger view of motherese supports Falk's claim that the social-emotional elements of language are primary and suggests that language and music have common evolutionary foundations.
