The detrimental effects of lead exposure in children have been known for over 100 years. Although a few initial measures implemented about 30 years ago were effective in somewhat reducing levels of lead exposure in children, relatively little has been done recently from a policy perspective to protect children from lead. We now know from recent…

In spite of numerous recent outcome studies of extremely low birth weight (ELBW) infants, no data exist on their development prior to term. In this study we traced and compared the neurobehavioral development of 251 ELBW (less than 1,000 g) and 240 low birth weight (LBW; 1,000 g-2,500 g) preterms born between 1995 and 2004 from 32 to 37 weeks…

The purpose of this study was to provide insight regarding the impact that the alternative to suspension program Achievement Character Excellence (ACE) has on the students who are placed there. The study utilized four achievement indicators to track the level of improvement of students after they were placed in the ACE program and after they were…

Gottlieb's (1991/2007) study on social malleability of ducking response to maternal calls is perhaps a paradigmatic example of research within the transactional approach to behavioral development--an approach which has fundamental links with the ecological approach to perception-action (Gibson, 1979). This commentary fleshes out these links…

Is human ontogenesis a product of evolution or a result of individual decisions and actions? In the present paper we aim at solving this apparent conflict between a behavioral genetics approach and an action-theoretical perspective to human development. After a discussion of the idea of active and intentional self-development and the role of genes…

In addition to his pioneering studies on prenatal development of social responses in the mallard, Gilbert Gottlieb made important theoretical contributions to the study of the evolution of behavior. This tribute to Gottlieb presents his early view that prenatal behavioral development is the product of evolution and his revision of this view in his…

Approximately 20,000 children are adopted from foreign countries each year. Of these children, approximately 46% are adopted before they are 12 months old and 43% are adopted between 1 and 4 years of age. The development of children adopted from abroad before or by 2 years of age is the focus of this article. Given the impoverished language input…

While both positive and negative peer interactions have long been a focus of scientific interest, much less attention has been given to children who tend to refrain from interacting with peers. This volume brings together leading authorities to review progress in understanding the development, causes, and consequences of shyness and social…

This volume brings together leading authorities from multiple disciplines to examine the relationship between brain development and behavior in typically developing children. Presented are innovative cross-sectional and longitudinal studies that shed light on brain-behavior connections in infancy and toddlerhood through adolescence. Chapters…

The authors of the present study addressed the measurement of temperament by examining the convergence between observational and questionnaire measures and the occurrence of contrast effects in parental ratings of nontwin siblings on the Children's Behavior Questionnaire. Fathers', mothers', and observers' ratings of 94 early-school-age sibling…

The current study investigated child behavioral change during the early years of elementary school. Behavioral Assessment System for Children (BASC; Reynolds & Kamphaus, 1992) teacher ratings of child behavior were collected over a three-year period. The sample consisted of 162 children measured yearly between first and third grade.…

Adaptation of internationally adopted children to another culture and language has not been studied extensively. This study followed four infant girls from China during the 1st year postadoption, measuring vocabulary, gestural, social, communication, and symbolic behavior development each month. The children were also tested at 2 and 3 years…

Near the end of his illustrious career, Gottlieb lamented the continued dominance of heritability analysis in human psychology and the difficulties in winning support for the developmental point of view. Recent, spectacular progress in molecular genetic neuroscience and the genetic study of behavior, however, is rendering heritability analysis…

The purpose of the study was to examine the contributions of maternal encouragement of autonomy and maternal encouragement of connectedness to the prediction of children's social behaviors. A sample of children (N = 94), initially aged two years, and their mothers in China participated in the two-year longitudinal study. Child autonomy and…

Although we are far from a universally accepted pattern of impaired function at altitude, there is evidence indicating motor, perceptual, memory and behavioural deficits in adults. Even relatively low altitudes (2500 m) may delay reaction time, and impair motor function. Extreme altitude exposure (greater than 5000 m) may result in more pronounced…
