Mothers whose infants varied in early biological characteristics (born at term, n = 120; born at very low birth weight [VLBW], n = 144) were randomized to a target group (n = 133) or developmental feedback comparison group (n = 131) to determine whether learning responsive behaviors would facilitate infant development. The target condition included(More)
The relationship of gestural joint attention behaviors and the development of effective communication skills in autism and developmental language delay (DLD) was investigated. Autistic and DLD children matched for MA and MLU were compared on measures of gestural joint attention behavior, personal pronoun use, and spontaneous communicative behavior. DLD(More)
The role of early versus ongoing maternal responsiveness in predicting cognitive and social development was examined in home visits for mothers, full-term children (n = 103), and medically low-risk (n = 102) and high-risk (n = 77) preterm children at 5 ages. There were 4 maternal clusters based on warm and contingent responsiveness behaviors observed early(More)
OBJECTIVE To characterize neuroimaging, physical, neurobehavioral, and developmental findings in children with inflicted and noninflicted traumatic brain injury (TBI) and to identify characteristic features of inflicted TBI. METHODS AND PATIENTS Forty children, 0 to 6 years of age, hospitalized for TBI who had no documented history of previous brain(More)
Growth modeling was used to examine the relation of early parenting behaviors (averaged across 6 and 12 months) with rates of change in children's cognitive-language and social response and initiating skills assessed at 6, 12, 24, and 40 months. Groups of full-term (n = 112) and very low birth weight children, divided into medically low (n = 114) and high(More)
AIM To understand the relationship between cognition and white-matter structure in adolescents born preterm without obvious brain injury. METHODS Thirty-two adolescents from a longitudinal study of child development were selected according to risk of developmental disorders at birth (born at term: eight males, five females; median age 16y 1mo,(More)
The present study examined whether parenting and child characteristics of 2- and 3 1/2-year-old children had common paths of influence on their 4 1/2-year independent cognitive and social functioning. Structural equation modeling was guided by hypotheses that assumed children's later independence is facilitated by specialized parental support in early(More)
This study examined the optimal timing (infancy, toddler-preschool, or both) for facilitating responsive parenting and the intervention effects on maternal behaviors and child social and communication skills for children who vary in biological risk. The intervention during infancy, Playing and Learning Strategies (PALS I), showed strong changes in maternal(More)
Using structural modeling, we examined the influence of mothers' verbal input that provided information about associations between objects and actions (scaffolding) at 3 and 4 years of age on children's 6-year executive processing skills. Executive processing skills were measured by search retrieval and independent goal-directed play tasks. A set of 4-year(More)
12-month-old infants with Down syndrome (n = 14) and mental and motor age-matched high-risk preterm infants (n = 14) were studied with respect to their ability to attend to and explore their environment in interactions with their mothers. The effectiveness of particular maternal attention-directing techniques in modifying infant responses to toys was(More)
