Exposure to environmental pollutants has been associated with cellular aging in children and adolescents. Individuals may vary, however, in their sensitivity or vulnerability to the effects of environmental pollutants. Larger hippocampal volume has emerged as a potential index of increased sensitivity to social contexts. In exploratory analyses…

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…

Child environmental health (CEH) science has identified numerous effects of early life exposures to common, ubiquitous environmental toxicants. CEH scientists have documented the costs not only to individual children but also to population-level health effects of such exposures. Importantly, such risks are unequally distributed in the population,…

Climate change-related disasters have drawn increased attention to the impact of air pollution on health. 122 children ages 9-11 years old, M(SD) = 9.91(.56), participated. Levels of particulate matter (PM2.5) near participants' homes were obtained from the Environmental Protection Agency. Cytokines were assayed from 100 child serum samples: IL-6,…

The purpose of this study was to conduct a small-scale pilot study of Conjoint Behavioral Consultation (CBC), modified for middle school students with social, emotional, and behavioral concerns. Participants were 30 middle school students with social, emotional, and behavioral concerns, along with their parents and teachers. Participants were…

Assessing the effect mentors have on their mentees is methodologically challenging: most programs merely provide relatively short mentoring durations (typically in the range of 1 year), age ranges are usually rather small, and examining dyads with anything other than questionnaires has proven to be challenging in the past. Thus, although some…

The present study explores moral identity, moral emotion attribution, moral responsibility, acceptability, and moral decisions in adolescents. We hypothesized that moral identity predicts moral decisions in adolescents. Furthermore, we hypothesized that moral emotions mediate the relationship between moral identity and moral decisions and moral…

Intellectual giftedness is commonly associated with a high level of intellectual functioning, an identification process whereby individuals are labeled as "gifted," and adjustments in schools such as grade skipping. During adolescence, all these factors are prone to reduce peer connectedness and school life satisfaction. The aim of the…

Despite empirical and epidemiological research indicating that risk taking propensity increases across adolescence, it is unknown whether this is true for positive risk taking. Additionally, adolescents' decisions are heavily influenced by their social environment, but it is unclear to what extent social influences are associated with positive…

This study examined the effects of group art therapy on self-concept and peer relationships among adolescents using a mixed-method approach. Twelve recruited adolescents from a high school in Northern Taiwan attended weekly 2-h group art therapy sessions for 8 weeks. Through a discovery-oriented approach incorporating focus group interviews and…

The present study examined how maltreatment experience was associated with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) symptoms in children under institutional care. The key caregivers of children and adolescents aged 6 to 18 years who were under institutional care in Nagano prefecture, Japan were asked to…

Given the significant amount of time that refugee and asylum-seeking children (RASC) spend in schools, these institutions play an important role in their lives and represent an ideal environment in which to help them to adapt to their host society. The present study aimed to draw attention to the possibility of transferring intervention methods…

This research aims to understand how children conceptualise lying and how they associate it with moral reasoning within a narrative that contains everyday moral transgressions. This study also explores whether children are willing to lie when they are asked to do so by close adults, such as mothers, fathers and teachers, even after declaring that…

Developmental researchers commonly utilize multilevel models (MLMs) to describe and predict individual differences in change over time. In such growth model applications, researchers have been widely encouraged to supplement reporting of statistical significance with measures of effect size, such as R-squareds ("R[superscript 2]") that…

Longitudinal panel studies are widely used in developmental science to address important research questions on human development across the lifespan. These studies, however, are often challenging to implement. They can be costly, time-consuming, and vulnerable to test--retest effects or high attrition over time. Planned missingness designs (PMDs),…
