Reciprocity in mother-infant vocal interactions: Relationship to the quantity of mothers' vocal stimulation.

Abstract

A study of 147 mother-infant dyads revealed that the most talkative mothers did not allow their infants to initiate many conversations. The least talkative mothers ignored many of their infants' vocalizations. Mothers in the mid-level talking range demonstrated the greatest reciprocity, allowing their infants to initiate more conversations.
