Social-communication differences are a robust and defining feature of autism spectrum disorder (ASD) but identifying early points of divergence in infancy has been a challenge. The current study examines social communication in 9- to 12-month-old infants who develop ASD (N = 30; 23% female; 70% white) compared to typically developing (TD) infants…

Investigates 8-, 11-, 14- and 17-year-old students' choices of either a familiar adult or peer, or an adult or peer expert to provide counsel. The findings support the conceptualization that adult-child relations are transformed from unilateral dependence in childhood to increasing mutuality in adolescence. (RJC)

Compares 17 methadone-exposed and 23 control four-month-old infants in interactions with their mothers. Results indicate that methadone is only one of several risk factors affecting interaction. Mothers rated poor in communication have poor psychosocial and psychological resources, and infants rated poor in communication showed problematic motor…

Examined infants' tendency, from a few days to nine months of age, to prefer infant-directed over adult-directed speech. Results suggest that exaggerated pitch contours that characterize infant-directed speech may become salient communicative signals for infants through language-rich, interactive experiences with caretakers and increased…

Examined children's developmental trajectories in five domains. Children were assigned to same- or mixed-age child care groups and assessed at 6-month intervals between approximately 32 and 49 months. Children in the two groups differed in their trajectories for communication, cognitive, and motor development but showed similar trajectories for…
