Analysis of adult-neonate synchrony during speech and nonspeech.
Five neonates and two adult female interactants were video-taped and categorized as to their interactionally synchronous movements during speech and nonspeech. Although synchrony occurred during speech as well as nonspeech, it was significantly more likely to occur during periods of speech. Duration of adults' movement were significantly shorter during speech and longer during nonspeech. These findings corroborate previous suggestions that interactional synchrony between adults and infants occurs on a micro-level.
