Prior work has conceptualized children's executive function and self-regulation skills as relatively stable across short periods of time. Grounded in long-standing contextual theories of human development, this study introduces a new observational tool for measuring children's regulatory skills across different naturally occurring situations…

The purpose of this study is to investigate the relations among children's symbolic functioning at 15 months, joint attention at 24 months, expressive communication at 24 and 36 months, and executive functioning at 36 months. With the sample from rural areas in the United States collected by the Family Life Project (N = 1,008), a longitudinal data…

The main goals of the study were to replicate and measure the test-retest reliability of a previously used preschool working memory task, to analyze the relationship between working memory and school readiness above and beyond attention and an indicator of overall development, and to investigate these relationships for gender differences.…

Executive function (EF) is considered a set of interrelated cognitive processes, including inhibitory control, working memory, and attentional shifting, that are connected to the development of the prefrontal cortex and contribute to children's problem solving skills and self regulatory behavior (Best & Miller, 2010; Garon, Bryson, &…

Across the country, school administrators and educators struggle to find time for children to engage in physical activity while still giving them enough time in academic instruction. The steep rise in childhood obesity in the U.S. (National Center for Health Statistics, 2011; Ogden, Carroll, Kit, & Flegal, 2014) suggests that the concern is…

This study examined longitudinal relations between early measures of prosocial action in infancy as well as cognitive and social-cognitive abilities, and the sharing behaviour of preschool children. The results reveal relations between delay-of-gratification at 24 months and inhibitory control at 30 months, and children's sharing at 5 years.…

This study examined developmental associations between growth in domain-general cognitive processes (working memory and attention control) and growth in domain-specific skills (emergent literacy and numeracy) across the prekindergarten year and their relative contributions to kindergarten reading and math achievement. One hundred sixty-four Head…
