Birth weight is a robust predictor of valued life course outcomes, emphasizing the importance of prenatal development. But does birth weight act as a proxy for environmental conditions in utero, or do biological processes surrounding birth weight themselves play a role in healthy development? To answer this question, we leverage variation in birth…

This article explores the relationship between toddlers' (age: 30-33 months) well-being (WB), play (PL), social-emotional competence (SC) and movement skills (MS). Two hypotheses were put forward for testing: (1) there is a significant positive correlation between WB, PL, SC and MS, and (2) toddlers' WB can be predicted from their PL, SC and MS.…

This longitudinal research examines maternal and child behaviors during joint planning over a 3-year period of middle childhood. 118 mother-child dyads were observed once a year beginning when the children were 8 years of age. Coding focused on mother and child planning behaviors, maternal instructional support, and child task engagement.…

By using a panel design in a sample of 298 undergraduate/master students at an Italian public university, the present study aimed to test longitudinally the interplay among environmental attitudes, pro-environmental behavior, social identity, and pro-environmental institutional climate. The relationships were tested with cross-lagged analysis…

This longitudinal study considers the contributions of language awareness to children's learning to read and spell. The aim of the study was to examine whether the connection between phonemic awareness and literacy in Greek is constant over time even when appropriate controls are taken into account. I examined this hypothesis with Greek Cypriot…

This study had three purposes and four hypotheses were tested. Three purposes: (1) To use hierarchical linear modeling (HLM) to investigate whether students' perceptions of their engineering career intentions changed over time; (2) To use HLM to test the effects of gender, engineering identification (the degree to which an individual values a…

This study examined children's expectancies about interactions with own- and other-gender peers. Goals were to examine expectancies about the outcomes related to own- versus other-gender group interactions, assess cohort and temporal changes in expectancies, and assess the effect of expectancies on school-related outcomes. Students in second and…

This paper tests the hypothesis that stream placement influences teacher judgements of pupils, thus investigating a route through which streaming by "ability" may contribute to inequalities. Regression modelling of data for 800+ 7-year-olds taking part in the Millennium Cohort Study examines whether teachers' reported perceptions of…

We examined the prediction that the interaction between Glucocorticoid Receptor Gene ("NR3C1") methylation, stress, and experienced maternal support predicts anxious and avoidant attachment development. This was tested in a general population sample of 487 children and adolescents (44% boys, M[subscript age] = 11.84, SD[subscript age] =…

Our newly proposed integrated academic self-concept model integrates 3 major theories of academic self-concept formation and developmental perspectives into a unified conceptual and methodological framework. Relations among math self-concept (MSC), school grades, test scores, and school-level contextual effects over 6 years, from the end of…

Given that maternal support promotes healthy social and emotional development in early childhood, it is important to understand the predictors of such support, especially during emotional challenges. In this study, mothers' dispositional distress reactivity (i.e., the tendency toward experiencing distress in response to children's negative…

The relationship between public education expenditures and student outcomes remains an important concern for policy analysts, educational administrators, and the public at large. While previous studies have failed to identify a consistent relationship between public investments in education and positive student outcomes, most analyses have not…

Prior scholastic journalism research did not adequately address the possibility that journalism students perform better academically because of their backgrounds and inherent abilities. Using Education Longitudinal Study of 2002 data, this study shows that high school journalism attracts better students. Although for-credit and extracurricular…

This study examined the reciprocal longitudinal relations between homophobic attitudes and homophobic bullying at school. Furthermore, the study also assessed the roles of exposure to homophobic bullying at school, homophobic language at home, and previous social interaction with individuals who identify as lesbian, gay, bisexual, or transgender…

Objective: This study examined how freshman year substance use prospectively predicted time to college graduation, and whether delayed graduation predicted postponed adoption of adult roles and future substance use. Participants: Participants were part of a longitudinal study that began in 2004. The first analyses focused on freshman year (N =…
