Narrative story stem techniques (NSSTs) offer insight into attachment and other representational aspects of preschool to young school aged children's inner lives. While the method moved into the academic and clinical mainstream some 35 years ago, their applicability to "non-Western" contexts remains little understood. This synthesis…

The goal of this study was to track the progress of Italian children at risk for school failure enrolled in preschools based on the Reggio-Emilia approach. Risk factors considered included family socioeconomic status (SES), child receptive language, and child gender. Participants were 211 children (Mage = 60.8 months, 116 girls) in Reggio-inspired…

This study investigated the longitudinal trajectories of peer rejection and their predictive effects on Internet gaming addiction among Chinese children. The sample comprised 818 students from Grades 1 to 3 (M = 8.30, SD = 1.11, 51.3% boys). Peer rejection was assessed using peer nominations in five waves over a period of 2.5 years, and Internet…

Human observations can only capture a portion of ongoing classroom social activity, and are not ideal for understanding how children's interactions are spatially structured. Here we demonstrate how social interaction can be investigated by modeling automated continuous measurements of children's location and movement using a commercial system…

Social norms are vital for the functioning of adolescent peer groups; they can protect the well-being of groups and individual members, often by deterring harmful behaviors, such as aggression, through enforcement mechanisms like peer victimization; in adolescent peer groups, those who violate aggression norms are often subject to victimization.…

Social anxiety is a common mental disorder with an average age of onset in early adolescence. Current theories focus largely on risk factors that are present from early in life, but reasons for onset of the disorder as youth move into adolescence are rarely discussed. We recently proposed a model of the onset of certain mental disorders during the…

We examined how two different definitions of cross-ethnic friendships, namely reciprocal peer nominations for shared activities and mutual trust, predict attitudes towards immigrant students among non-immigrant Swiss children and early adolescents (N = 309). Among both Swiss children and early adolescents, only the number of mutually trusting peer…

Though it is well-established that self-esteem develops from childhood well into old age, little is known about the processes that influence this change, especially among young populations. This international, cross-sequential study examined the development of self-esteem in 1599 second-graders (Age M[subscript T1] = 7.99, SD[subscript T1] = 0.52…

Cultural and socioeconomic differences in children's perceptions of their peers as being typical members of the cis gender group were examined in a cross-sectional sample of 351 girls (N = 164) and boys from 19 fifth- and sixth-grade classrooms (M age = 11.5) in three primary schools in Montréal (N = 156) and two schools in Barranquilla.…

Evidence of cultural comparisons of gender-identity-measurement scales is scarce. The present study aims to assess the scalar invariance of two dimensions of a widely used gender identity scale (Egan and Perry's Multidimensional Gender Identity Inventory) across two cultural contexts. Fourth, sixth, and fifth graders from Barranquilla (Colombia)…

Theory of mind is one of the most important cognitive factors in social information-processing, and deficits in theory of mind have been linked to aggressive behavior in childhood. The present longitudinal study investigated reciprocal links between theory of mind and two forms of aggression--physical and relational--in middle childhood with three…

The present study assesses the factor structure, psychometric adequacy, and invariance across sex and age of the Relational Provisions Loneliness Questionnaire (RPLQ). Discriminant validity with an external criterion was also tested. In a sample of Portuguese adolescents, from 7th to 9th grade (N = 817), Confirmatory Factor Analyses (CFA) were…

Extant literature suggests that oppositional defiant disorder (ODD) and callous-unemotional (CU) behaviors in childhood and adolescence are associated with distinct patterns of psychophysiological functioning, and that individual differences in these patterns have implications for developmental pathways to disorder. Very little is known about the…

Internationally, girls outperform boys in overall school performance. The gender gap is particularly large among those in at-risk groups, such as children from families at economic disadvantage. This study modeled the academic trajectories of a low-income sample of boys and girls from the Concordia Longitudinal Risk Project across the full course…

Executive functions (EFs) may help children to regulate their food-intake in an "obesogenic" environment, where energy-dense food is easily available. There is mounting evidence that overweight is associated with diminished hot and cool EFs, and several longitudinal studies found evidence for a predictive effect of hot EFs on children's…
