Effect of Infants' Utterance Duration on Joint Coordinated Engagement (JCE) Scores

This figure depicts that a longer duration of infants' utterances is correlated with a higher joint coordinated engagement score (JCE) in video chat, while the longer duration of infants' utterances is correlated with a lower JCE in the face-to-face with a shared tablet condition. The size of the dots and triangles corresponds to the number of utterances. Larger sizes represent a greater number of utterances.
