We examined developmental trajectories of attention-deficit/hyperactivity disorder (ADHD) symptoms, standardized achievement, and school performance for adolescents with and without ADHD who did and did not enroll in postsecondary education (PSE; N = 749; 79% boys; 63% White, 17% non-Hispanic Black, 10% Hispanic, and 10% other ethnicities). In a…

Algebraic competence is a major determinant of college access and career prospects, and equal sign knowledge is taken to be foundational to algebra knowledge. However, few studies have documented a causal effect of early equal sign knowledge on later algebra skill. This study assessed whether second-grade students' equal sign knowledge…

Numerous studies suggest an association between language and executive function (EF), but evidence of a developmental relationship remains inconclusive. Data were collected from 75 deaf/hard-of-hearing (DHH) children and 82 hearing age-matched controls. Children were 6-11 years old at first time of testing and completed a battery of nonverbal EF…

This study investigated bidirectional links between the quality of teacher-child relationships and children's interest and pre-academic skills in literacy and math. Furthermore, differences in the patterns of bidirectionality between boys and girls were explored. Participants were 461 Finnish kindergarteners (6-year-olds) and their teachers…

Anti-racist efforts require talking with children about race. The present work tested the predictors of U.S. adults' (N = 441; 52% female; 32% BIPOC participants; M[subscript age] = 35 years) conversations about race with children across two timepoints in 2019. Approximately 60% of adult participants talked to their children (3-12 years) about…

The current study examined relations between distinct aspects of moral functioning, and their cognitive and emotional correlates, in preschool age children. Participants were 171 typically developing 3- to 6-year-olds. Each child completed several tasks, including (a) moral tasks assessing both performance of various moral actions and evaluations…

Historic racial disparities in the United States have created an urgent need for evidence-based strategies promoting African American students' academic performance via school-based ethnic-racial socialization and identity development. However, the temporal order among socialization, identity, and academic performance remains unclear in extant…

Understanding the cognitive processes central to mathematical development is crucial to addressing systemic inequities in math achievement. We investigate the "Groupitizing" ability in 1209 third to eighth graders (mean age at first timepoint = 10.48, 586 girls, 39.16% Asian, 28.88% Hispanic/Latino, 18.51% White), a process that captures…

This 2-year longitudinal study examined relations between enjoyment of learning in Chinese and mathematics, two major subjects in Chinese schools, and indexes of school performance. The participants included 1041 students (501 boys) initially in third, fifth, and seventh grades (mean age = 10.49 years) in China. Data on enjoyment of Chinese and…

This study examined how intergroup processes and social-cognitive factors shape bystander responses to bias-based and general bullying. Participants included sixth and ninth graders (N = 179, M = 13.23) who evaluated how likely they would be to intervene if they observed bullying of immigrant-origin and nonimmigrant-origin peers. Adolescents'…

This study of 195 (108 boys) children seen twice during infancy (Time 1: 4.12 months; Time 2: 14.42 months) aimed to investigate the associations between and infant predictors of executive function (EF) at 14 months. Infants showed high levels of compliance with the EF tasks at 14 months. There was little evidence of cohesion among EF tasks but…

Little is known about how children's value priorities develop over time. This study identifies children's value priority profiles and follows their development during middle childhood. Australian children (N = 609; ages 5-12 at Time 1) reported their values over 2 years. Latent Transition Analysis indicated four profiles: Social-Focus, Self-Focus,…

The maternal language input literature suggests that mothers with more education use a greater quantity and complexity of language with their young children compared to mothers with less education although race and socioeconomic status have been confounded in most studies because of small sample sizes. The current Family Life study included a…

Little research has considered whether prenatal experience contributes to executive function (EF) development above and beyond postnatal experience. This study tests direct, mediated, and moderated associations between prenatal risk factors and preschool EF and IQ in a longitudinal sample of 1,292 children from the Family Life Project. A composite…

Parents visiting a gear exhibit at a children's museum were instructed to encourage their children (N = 65; ages 4-6) to explain, explore, or engage as usual. Instructions led to different patterns of play at the exhibit: Encouragement to explain led to greater discussion of gear mechanisms, whereas encouragement to explore led to more time…
