Executive functions (EF) are crucial to regulating learning and are predictors of emerging mathematics. However, interventions that leverage EF to improve mathematics remain poorly understood. 193 four-year-olds (mean age = 3 years; 11 months pre-intervention; 111 female, 69% White) were assessed 5 months apart, with 103 children randomised to an…

Sleep is a robust predictor of child and adolescent development. Race/ethnicity, socioeconomic status (SES), and related experiences (e.g., discrimination) are associated with sleep, but researchers have just begun to understand the role of sleep in the development of racial/ethnic and SES disparities in broader psychosocial adjustment and…

Parenting is widely considered to be among the most important influences on early childhood (EC) development. But to what extent and under what circumstances can EC parenting programs improve child learning outcomes? While substantial progress has been made toward addressing these questions in recent years, there have been few attempts to…

Differences in socioeconomic status (SES) correlate both with differences in cognitive development and in brain structure. Associations between SES and brain measures such as cortical surface area and cortical thickness mediate differences in cognitive skills such as executive function and language. However, causal accounts that link SES, brain,…

The current study investigated the effects of metacognitive and executive function (EF) training on childhood EF (inhibition, working memory [WM], cognitive flexibility, and proactive/reactive control) and academic skills (reading, reasoning, and math) among children from disadvantaged backgrounds. Children (N = 134, M[subscript age] = 8.70 years)…

Despite a robust literature examining the association between sleep problems and cognitive abilities in childhood, little is known about this association in toddlerhood, a period of rapid cognitive development. The present study examined the association between various sleep problems, using actigraphy, and performance on a standardized test of…

The socioeconomic attainment gap in mathematics starts early and increases over time. This study aimed to examine why this gap exists. Four-year-olds from diverse backgrounds were randomly allocated to a brief intervention designed to improve executive functions (N = 87) or to an active control group (N = 88). The study was preregistered and…

This study, using longitudinal data from the South African Birth to Twenty Plus study, assessed associations between early childcare quality in the home between six months and two years, household SES and cognitive development at age 5. Childcare quality was assessed using measures of maternal responsiveness and cognitive stimulation. Cognitive…

The aim of this study is to examine the attitudes of high school students towards mind and intelligence games and how these attitudes differ based on various variables. The study population consists of 800 students studying in different departments at Konya Selçuklu Türk Telekom Vocational and Technical Anatolian High School during the 2023-2024…

Theorists and researchers have been discussing the relationship between social class background and differences observed in cognitive ability test points of children from lower social class families and their middle or upper SES peers. It has been discussed that for a "more detailed understanding" of these cognitive inequalities, it…

Measurement of early childhood development at the population level has traditionally been neglected in Latin America. In this context, Uruguay stands out for having two population-based protocols: the Nutrition, Child Development and Health Survey (ENDIS), a home survey, and the School Readiness - Child Development Inventory (INDI). This paper…

In this study (n = 1000, M[subscript age at K1entry] = 53.4 months, SD = 3.4; 53% females), we investigated the contributions of the family socioeconomic status (SES; maternal education and an income-related measure) and number and age of siblings to the development of children's math, reading, and working memory (WM) updating skills over the…

The COVID-19 context has created the most severe disruption to education systems in recent history. Its impact on child development was estimated comparing two cohorts of 4- to 6-year-old Uruguayan children: control (n = 34,355, 48.87% girls) and COVID cohort (n = 30,158, 48.95% girls) assessed between 2018 and 2020 in three waves, by a routinely…

In 1968, Paul Freire brought to the world, "Pedagogy of the Oppressed." The way he categorized "the haves and have nots" still resonates with the wealth disparity in the United States. The need to create a level of equity in education by providing equal access was fundamental in his philosophy (Freire, 1968). Similarly,…

This study used a machine learning framework in conjunction with a large battery of measures from 9,718 school-age children (ages 9-11) from the Adolescent Brain Cognitive Development[superscript SM] (ABCD) Study to identify factors associated with fluid cognitive functioning (FCF), or the capacity to learn, solve problems, and adapt to novel…
