Inuit communities in Northern Quebec (Canada) are exposed to environmental contaminants, particularly to mercury, lead and polychlorinated biphenyls (PCBs). Previous studies reported adverse associations between these neurotoxicants and memory performance. Here we aimed to determine the associations of pre- and postnatal exposures to mercury, lead…

Children are exposed to many trace elements throughout their development. Given their ubiquity and potential to have effects on children's neurodevelopment, these exposures are a public health concern. This study sought to identify trace element mixture-associated deficits in learning behavior using operant testing in a prospective cohort. We…

Talent development constitutes an important phenomenon of human development; yet it is rarely considered a mainstream topic in the field of child and adolescent development. Conversely, in the field of gifted and talented studies, various talent development (TD) models developed in the past have had minimal interaction with the literature on child…

Developmental scientists are often interested in subgroups of people who share commonalities in aspects of development; these subgroups often cannot be captured directly but instead must be inferred from other information. Mixture models can be used in these situations. Two specific types of mixture models, latent profile transition analyses and…

Grandmothers are important in Chinese families. This study explored the early emerging mother-grandmother-infant network and its association with child's socioemotional development in multigenerational families in a non-WEIRD country. The analytic sample included 60 children (T1: M[subscript age] = 6.5 months) and their caregivers residing in…

Although peer relations are recognized as a fundamental developmental context, they have been rarely studied as a means of understanding the effects of socioeconomic status and inequality. In this paper, we show how and why peer relations provide a unique and powerful opportunity to assess the differential risks and resources available in the peer…

With increasing rates of globalization, understanding the cultural factors that promote positive adaptation in migrant children and adolescents is vital. In prior research, acculturation and enculturation frameworks often rely on unidimensional or bidimensional conceptions of culture to study the effects of migration on child and adolescent…

The research presented in this Issue impressively documents the great variety of conditions of live that impact child and adolescent migrants' development. The studies conducted in various receiving countries include young refugees as well as the first- and second-generation offspring of migrant families who left their homes in different areas of…

Although children's school success is a parental goal in most cultures, there is wide cultural variation in the qualities that parents most wish their children to develop for that purpose. A questionnaire contained forty-one child qualities was administered to 757 parents in seven cultural communities in Australia, Italy, the Netherlands, Poland,…

This chapter highlights the key assumptions underlying Randomized Control Trials (RCTs) and illustrates them with regard to the practice of RCTs in the realm of child and adolescent development. Given the prominence of RCTs in policy research, we analyze the possible ways in which these assumptions might not be met by single randomized…

The behavior of newborns is ambiguous. Cultural models--representations shared by members of a community--provide new parents and others with a cognitive and motivational structure to understand them. This study asks members of several cultural groups (total n = 100) to judge the "similarity" of behavioral items in the Neonatal…

Iron is needed for normal development in adolescence. Exposure to individual environmental metals (e.g., lead) has been associated with altered iron status in adolescence, but little is known about the cumulative associations of multiple metals with Fe status. We used data from the 2017-2018 National Health and Nutrition Examination Survey…

Early attachment has been commonly hypothesized to predict children's future developmental outcomes, and robust evidence relying on assessments of single caregiver-child attachment patterns has corroborated this hypothesis. Nevertheless, most often children are raised by multiple caregivers, and they tend to form attachment bonds with more than…

How can high potential in childhood be transformed into outstanding adult accomplishment? Research indicates that individuals who become outstanding performers and producers have more than just raw talent in the domain or opportunities to develop their talent--they have the will, drive, and focus to take advantage of the opportunities with which…

Environmental contaminants, which include several heavy metals, persistent organic pollutants, and other harmful chemicals, impair several domains of child development. This article describes four themes from recent research on the impact of environmental contaminants on child development. The first theme, disparities in exposure, focuses on how…
