Direction dependence analysis (DDA) is a recently developed method that addresses the need for more sophisticated tools to evaluate causal mechanisms of developmental processes and interventions. The present study applied DDA to evaluate the hypothesized mediators of a classroom behavior management training program on student academic competence.…

Mathematical and spatial reasoning abilities during childhood predict later success in male-dominated science, technology, engineering, and math (STEM) disciplines, yet relatively little is known about the affective correlates of children's math and spatial performance or gender differences therein. In the present research, we assessed math and…

We examined the development of children's positive and negative attitudes toward other-gender peers over 1 year, and explored the longitudinal social consequences of holding positive or negative attitudes on the beholder of these attitudes. Participants were 206 second graders (Mage = 7.18 yrs, SD = .56, 50% girls) and 206 fourth graders…

Prior research shows that when parents monitor, check, and assist in completing homework without an invitation, their children's motivation and academic achievement often decline. We propose that intrusive support from parents might also send the message that children are incompetent, especially if they believe their intelligence is fixed. We…

Data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 1,307) were used to estimate the additive and multiplicative benefits of high-quality child care between birth to 54 months of age and high-quality elementary school education between first and fifth grade. Results indicated…

We examined the development of sharing behavior of children (aged 6 to 12) within the unique, minority population of Christian Arab children in Israel (N = 319). Children had the opportunity to share candy with a needy or non-needy recipient. Parents' level of religiosity was assessed using the Duke University Religion Index questionnaire (DUREL).…

Differentiation hypotheses concern changes in the structural organization of cognitive abilities that depend on the level of general intelligence (ability differentiation) or age (developmental differentiation). Part 1 of this article presents a review of the literature on ability and developmental differentiation effects in children, revealing…

Elementary schoolchildren's working memory performance (WMP) fluctuates from moment to moment and day to day, yet the underlying mechanisms are not well understood. In the present study, affective states were investigated as predictors of these fluctuations. Interindividual differences in the intraindividual affect--WMP associations were expected,…

Research in developmental psychology has traditionally focused on parents' roles as agents of emotion socialization in their children's socioemotional development. By contrast, little longitudinal research has examined sociocultural mechanisms shaping parents' own emotional development. Immigrant parents are an ideal population in which to examine…

Concerns regarding the social-behavioral maladjustment of U.S. youth have spurred efforts among educators and policymakers to identify and remedy educational contexts that exacerbate children's anxiety, depression, aggression, and misconduct. However, investigations of the influence of collective classroom student characteristics on individuals'…

Prior evidence has suggested that preschoolers and elementary schoolers search information largely with no systematic plan when making decisions in probabilistic environments. However, this finding might be due to the insensitivity of standard classification methods that assume a lack of variance in decision strategies for tasks of the same kind.…

Although children often believe an adult's claims, they may have opportunities to check these claims by gathering relevant empirical evidence themselves. Here, we examine whether children seize such opportunities, especially when the claim is counterintuitive. Chinese preschool and elementary schoolchildren were presented with five different-sized…

This study investigated the role of school context in changes in the behaviors associated with having high social status during early adolescence. Three waves of surveys were collected from students (N = 542, 53% girls; 44% Black, 44% White, 5% Hispanic/Latinx, and 7% other; 60% free/reduced-fee lunch) in the middle of their sixth, seventh, and…

Accurate monitoring and control are essential for effective self-regulated learning. These metacognitive abilities may be particularly important for developing math skills, such as when children are deciding whether a math task is difficult or whether they made a mistake on a particular item. The present experiments investigate children's ability…

Previous studies suggest that the roots of school dropout (a) can be established early in life, (b) are likely to involve multilevel factors (home, child, classroom) operating prior to and during the elementary school years, and (c) can be identified by 3rd grade. The decision to drop out of school is thus a dynamic developmental process that can…
