Rhythms of dialogue in infancy: comments on Jaffe, Beebe, Feldstein, Crown, and Jasnow (2001)

Analysis of coordinated interpersonal timing has become an important tool for the study of infant-adult, peer, and marital interactions. Past research suggests that social coordination is informative about the quality of the caregiver-child social relationship. Does infant experience of certain types of coordination and pattern in early social interactions with caregivers predict better cognitive and social developmental outcomes? The recent monograph "Rhythms of dialogue in infancy" (Jaffe, Beebe, Feldstein, Crown, & Jasnow, 2001) provides the strongest evidence to date that it does. Moderately coordinated social interactions in early infancy predicted the most favorable developmental outcomes, and degree of coordination was influenced by contextual factors such as setting and nature of the relationship between the infant and its social interaction partner. This study provides a model for future research in this area and points toward important questions for future research on infant-caregiver social interactions.
