Presents a conceptual framework to guide understanding of the peer network. Uses this network approach to study changes in younger adolescents' popularity over a six-month period. Reports that changes in popularity are related to the child's initial level of aggression, observable prominence, and the popularity of the child's best friend.…

Investigated effect of classroom type (DAP versus DIP) on stress behaviors and activity participation of 102 preschool children as moderated by socioeconomic status (SES) and sex. Found twice the level of overall stress behavior in DIP classrooms, with lower SES children and males (during small motor/paper-and-pencil activities) exhibiting…

A study examined associations between bilateral visual acuity and depression among 391 Cuban Americans, 1,514 Mexican Americans, and 527 Puerto Ricans. Among Mexicans, depression was higher for those with moderate and greater impairment. Among Cubans, depression was higher for those with a distance visual acuity worse than 20/50. (Contains…

Examined ability of individuals biologically predisposed to poor spatial skills to capitalize on opportunities to develop these skills. Found that for girls with brothers, those from all right-handed families had lower mental-rotation scores than did others. Among children participating in mental-rotation-type activities with their brothers,…

Tested hypotheses from an organizational-developmental model for childhood resilience among 7- to 9-year olds. Found that caregiving factors and early development differentiated children with resilient and stress-affected adaptations. Variables reflecting emotionally responsive, competent parenting were direct, proximal predictors of resilience…

A study documented and analyzed the attendance of 155 children (birth-36 months) in an inner city early intervention program as related to several factors, including demographic information, caregivers' perception of the child's disability, and the teaching staff's perception of a child's cognitive and motor disabilities.

A study of 270 children (ages 1-22) with emotional or behavior problems found symptoms, functioning, and risk were significantly related to child strengths, and children in home-like settings were found to possess significantly higher levels of strengths than children in non-homelike settings. Child strengths were significantly associated with…

Examined relationship of helplessness exhibited in 112 kindergarten children's responses to a challenging, developmentally appropriate task with depression and negative self-worth 5 years later. Found that helplessness in kindergarten predicted more depressive symptoms, as reported by children and their teachers, and more negative feelings of…

The role of temperament was explored as a predictor of preschoolers' literacy and numeracy skills. Hierarchical regression analyses revealed that temperament contributed uniquely to the explanation of literacy and numeracy skills over and above well-established indicators of a child's academic achievement such as parent education, gender, and…

A study of 171 students in management classes taught by 3 professors found that the congruence between student and professor personalities was a significant predictor of student performance. Significant predictors of satisfaction were (1) congruence between students' ideal class and the actual environment and (2) congruence between student values…

Examined effects of four coping dimensions on conduct problems, depression, and achievement in multiethnic, inner- city sample of early adolescents. Found that for girls, interactions of active coping with family and community stress revealed a classic stress-buffering effect for active coping. Findings for boys did not support this effect.…

Examined the role of early versus ongoing maternal responsiveness in predicting cognitive and social development for full-term and preterm children (low- and high-risk) at five ages. Found that children, especially preterm children, showed faster cognitive growth when mothers were consistently responsive. Social growth was similar in the…

A longitudinal study involving 85 winners of the Westinghouse Science Talent Search investigated variables that led to their retention or attrition in science. Results found certain family variables, appeal of other domains of study, and shrinking grant money and academic positions contributed to attrition. The influence of mentors is discussed.…

A study of 162 maltreated children found significant risk factors within mothers' backgrounds were: younger than 20, lower educational achievement, sexual abuse history, absence of father during childhood, and history of psychiatric illness. Factors for fathers included: younger than 20, lower educational achievement, in care during childhood, and…

Rats obtained food-pellet reinforcers by nose poking a lighted key. Experiment 1 examined resistance to extinction following single-schedule training with different variable-interval schedules, ranging from a mean interval of 16 min to 0.25 min. That is, for each schedule, the rats received 20 consecutive daily baseline sessions and then a session…
