Evaluates what has been learned regarding the impact of early close relationships on psychological development, by examining the origins of continuity and change in attachment security and its prediction of later behavior. Evaluates research on impact of changing family circumstances and quality of care on attachment security. Offers new…

Using longitudinal data collected over 2 years on a sample of 2,745 urban elementary school children (1st-6th graders, ages 6-11 years) from economically disadvantaged communities, effects of stressful experiences within 3 contexts (school, family, neighborhood), cumulative stress, and multiple context stress on 3 indices of children's adjustment…

Investigated the development of inattentiveness and hyperactivity in middle childhood through a prospective study that followed 191 children from birth through age 11. In early childhood, quality of caregiving better predicted distractibility, an early precursor of hyperactivity, than did early biological or temperament factors. Caregiving and…

Examined the role of individual characteristics and peer influences in evoking early substance abuse in young boys. Individual characteristics, such as fighting, hyperactivity, oppositional behaviors, and likability, were found to be pivotal in the development of substance abuse--more than friends' deviance. Results suggest that prevention…

Examined relationship between child behavior and peer preference from the person-group similarity and the social-skill models with 2,895 first graders. Found support for both predictive models, with the acceptability aggression and withdrawal varying across classrooms and the effects of inattentive/hyperactive behavior and prosocial behavior…

Examined if and how differences in functioning of single-mother and two-parent families relate to occurrence of behavioral problems among inner-city boys ages 10-15. Findings included (1) multiple family risk factors contribute to occurrence of behavior problems; (2) most family risk factors were generalizable to both single-mother and two-parent…

Data from national sample of 3- to 16-year-olds show that lower test scores and increased behavior problems of children of younger mothers resulted from family background rather than maternal age. For nonfirstborns, maternal age at first birth, not at child's birth, influenced test scores. Disadvantage of children born to younger mothers was…

Observed home interaction between parents and 2- and 4-year-olds at Time 1 and 2 years later. Found that parent mental state talk to children varied by child's age, context of talk, and parent gender. Four-year-olds with older siblings produced and heard more cognitive talk and less desire talk than children without older siblings. Time 1 family…

Examined how relational stressors and supports interface with aggression to influence early adjustment trajectories from Fall of kindergarten year to Spring of first grade. Found that with few exceptions, relational experiences predicted adjustment beyond children's aggressive risk status. Chronicity of aggressive risk status and relational…

Assessed mothers' childrearing attitudes and toddler behavior to predict mothers' emotions, attributions, parenting goals, and socialization strategies in response to vignettes depicting aggressive and withdrawn child behaviors two years later. Found that most child effects were moderated by maternal attitudes or gender effects. Authoritarian…

Examined association between infants' emotional reactivity and reliance on mother and cognitive and language development at 2 years. Found that infants with high reactivity and reliance on mother during emotion challenges had higher cognitive and language skills than infants with low reactivity and reliance. Poor developmental outcomes were…

Identified groups of economically disadvantaged children showing high externalizing behavior in first grade that persisted (persistent) or decreased (improver) in third grade, or low first- grade levels that were stable (unproblematic) or increased (new problem) in third grade. Found that verbal ability, behavioral impulsivity, parent…

Compared socialization, family, and mental health variables among 231 low socioeconomic status Hispanic and Anglo-American preadolescents and their mothers.

Used longitudinal data from a sample of African-American children of teenaged mothers in the Baltimore, Maryland, area to examine determinants of functional literacy in adulthood. Found that preschool cognitive and behavioral functioning predicted literacy in young adulthood. Family environmental factors that predicted literacy in young adulthood…

Predictive links between social difficulties in early childhood and problems in middle childhood were examined. Peer, teacher, and self-assessments of behaviors and difficulties were obtained. Early peer rejection and aggression predicted later externalizing difficulties. Early poor peer acceptance, social isolation, and social incompetence…
