The timing of turns in mother-infant interactions: A Longitudinal Study

Infant response times were calculated from the end of the mother’s utterance until the start of the infant’s vocalization. Maternal response times were calculated from the end of the infant’s vocalization until the start of the mother’s utterance. Negative response times indicate that the vocalization starts in overlap with the vocalization of the interaction partner. Within turn pauses are the pauses between two consecutive utterances of one speaker.
