Children acquire language embedded within the rich social context of interaction. This paper reports on a longitudinal study investigating the developmental relationship between conversational turn-taking and vocabulary growth in English-acquiring children (N = 122) followed between 9 and 24 months.

This study investigated the motion event language children and their parents engaged in while playing a board game. Children are sensitive to differences in manner and path at infancy, yet adult-like motion event expression appears relatively late in development. While multiple studies have examined how exposure to parent speech generally relates…
