Neighborhood is a key context where children learn to process social information; however, the field has largely overlooked the ways children's individual characteristics might be moderated by neighborhood effects. We examined 1,030 six- to 11-year-olds (48.7% female; 82% White) twin pairs oversampled for neighborhood disadvantage from the Twin…

Violent crimes and domestic violence are notoriously high in South Africa, which leaves many children defenceless to struggle with emotions such as loneliness and sadness. The healthy development and socialisation of children can be difficult in a society characterised by domestic tribulations, poverty, crime, single-parent homes, and absent…

Aims: This systematic analysis aims to address the research question -- do whole-school nurturing approaches show any impact in the short or long term on (1) emotional/behavioural, (2) cognitive/educational or (3) teacher/school variables? Rationale: Trauma or Adverse Childhood Experiences can have long-term consequences though causing problems in…

Conoley, Powers, and Gutkin (2020) called for an increased emphasis on models of psychological service delivery that are primarily indirect, adult-focused, and geared toward systems-level change in the schools. They asserted that research in school psychology should not focus on the problems of individual children and youth but address the…

This report examines the importance and multidimensional nature of well-being, in general, and the well-being of Black, Native, Latinx, and Asian youth involved in systems of care, in particular. These young people must navigate three significant challenges: typical developmental issues and stressors associated with child and adolescent…

Recent advances in molecular genetics and epigenetics are reviewed that have major implications for the bio-behavioral sciences and for understanding how organisms adapt to their environments at both phylogenetic and ontogenic levels. From a post-genomics perspective, the environment is as crucial as the DNA sequence for constructing the…

Successful transition practices are essential in moving students forward into new facets of learning and life. Noteworthy is the transition into kindergarten, as students experience a new environment, with new academic, social, and behavioral expectations. Research has reviewed teacher and student perceptions on this topic, but has traditionally…

Chaos in the home is a key environment in cognitive and behavioural development. However, we show that children's experience of home chaos is partly genetically mediated. We assessed children's perceptions of household chaos at ages 9 and 12 in 2337 pairs of twins. Using child-specific reports allowed us to use structural equation modelling to…

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…

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…

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…

Gilbert Gottlieb's theory of probabilistic epigenesis replaced the nature-nurture dichotomy, and similar oppositions, with an integrated account of the development of the entire behavioral phenotype. In that theory, invariant developmental outcomes cannot be identified with an organism's 'nature,' if by that term is meant a set of predetermined…

Paper presented at the Merrill-Palmer Conference on Research and Teaching of Infant Development, February 13-15, 1970. (JE)

Gilbert Gottlieb's formative role in establishing a science of experimental behavioral embryology is described. His experimental program on the development of species identification served as a model for developmental psychobiologists seeking alternatives to the nature-nurture dichotomies prevalent in the 20th century. Two of the major concepts…
