Developmental science has increasingly scrutinized how environmental hazards influence child outcomes, but few studies examine how contaminants affect disparities in early skill formation. Linking research on environmental inequality and early childhood development, this study assessed whether differences in exposure to neurotoxic lead explain…

This study examines the socioeconomic status gradients in children's well-being at school using data on the total population of Danish public school children age 6-11 (N = 147,994). Children completed the national well-being at school survey, an environment-specific self-report of satisfaction with school, social well-being at school, and…

Classifying people into categories not only helps humans simplify a complex social world but also contributes to stereotyping and discrimination. This research examines how social categorization develops by testing how language imbues with meaning otherwise arbitrary differences between people. Experimental studies (N = 129) with 2-year-olds…

Extensive research has explored the ability of young children to learn about the causal structure of the world from patterns of evidence. These studies, however, have been conducted with middle-class samples from North America and Europe. In the present study, low-income Peruvian 4- and 5-year-olds and adults, low-income U.S. 4- and 5-year-olds in…

This study examined young children's contact with individuals of high-wealth and low-wealth backgrounds and their behavior toward peers of these backgrounds in a resource distribution task. The sample included 72 ethnically diverse higher income children (M[subscript age] = 6.68 years, SD = 0.98 years). Contact with individuals of low-wealth…

This research examines the complex patterns by which distinct dimensions of critical consciousness may lead marginalized adolescents toward distinct forms of political action. Structural equation modeling was applied to nationally representative data from the Civic Education Study (2,811 ninth graders; M[subscript age] = 14.6), first establishing…

Poverty-related developmental-risk theories dominate accounts of uneven levels of household functioning and effects on children. But immigrant parents may sustain norms and practices--stemming from heritage culture, selective migration, and social support--that buffer economic exigencies. "Comparable" levels of social-emotional functioning in…

Mothers and fathers of 40 preschool children equally distributed by child gender and socioeconomic status (low and middle) were asked to predict the level of success for their child on 4 achievement-type tasks. (Author/JMB)

The social interactions of 60 mother-infant pairs were observed for 25 minutes in a seminaturalistic setting when the infants were 6 months old and again at 20 months. Forty-six of the infants were termed at high risk for later school failure due to the socioeconomic situations of their families. (Author)

It is suggested that altruism is a multidimensional concept and that in the young child its expression may in part reflect differing levels of cognitive development. (Authors)

Middle-class teachers were significantly more permissive and less puritanical in outlook, took more pleasure in the emotional aspects of teacher-pupil relationships, and showed less authoritarian attitudes toward children than did lower-class teachers. (Author/MB)
