In contrast to research that examines the effects of socioeconomic status (SES) and bilingualism on development by comparing clearly disparate groups, the present study investigated the role of subtle differences in these experiences for their joint impact on performance on a verbal fluency task and an executive function (EF) task. The study…

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…

Studies have demonstrated significant associations between executive function (EF) and reading ability. Many of these studies have evaluated this association through composite EF skills. In this study, we evaluated the indirect effects of working memory (WM) and cognitive flexibility (CF) in the relation between kindergarten socioeconomic status…

Parenting has a prominent role in predicting children's externalizing behaviors (EB). Although parenting behavior has been shown by prior research to mediate the relationship between parenting self-efficacy (PSE) as the cognitive aspect of parenting and child EB, the role of children's cognitive aspects in the relationship is not yet well…

Although broad associations between socioeconomic status (SES) and child executive functions (EFs) are well established, contextual factors that may matter for effects of SES on EF are not fully understood. This study used a bioecological approach to examine factors that may moderate SES-EF relations. A socioeconomically diverse sample of children…

Executive functions (EF), including working memory, inhibition, and cognitive flexibility, vary as a function of socioeconomic status (SES), with children from economically disadvantaged backgrounds having poorer performance than their higher SES peers. Using observational methods, we investigated cognitive stimulation in the home as a mechanism…

The number of Chinese children living in poverty has risen steadily in Hong Kong, China. However, little is known on the longitudinal effects of family socioeconomic status (SES) on cognitive-linguistic skills, word reading and writing in children from low-SES backgrounds. This study examines differences in cognitive-linguistic skills and word…

This article examined longitudinal relations among socioeconomic risk, maternal language input, child vocabulary, and child executive function in a large sample (N =1,009) recruited for a prospective longitudinal study. Two measures of maternal language input derived from a parent- child picture book task, vocabulary diversity and language…

This article examined longitudinal relations among socioeconomic risk, maternal language input, child vocabulary, and child executive function (EF) in a large sample (N = 1,009) recruited for a prospective longitudinal study. Two measures of maternal language input derived from a parent-child picture book task, vocabulary diversity (VOCD), and…

Although there is substantial evidence that socioeconomic status (SES) predicts children's executive function (EF), the mechanisms underlying this association are poorly understood. This study tested the utility of two theories proposed to link SES to children's EF: the family stress model and the family investment model. Data came from the…

Socioeconomic status (SES) and bilingualism have been shown to influence executive functioning during early childhood. Less is known, however, about how the two factors interact within an individual. By analyzing a nationally representative sample of approximately 18,200 children who were tracked from ages 5 to 7 across four waves, both higher SES…

To determine whether patterning instruction was as useful or more useful than other forms of instruction, kindergarten children (age five) were taught either patterning or early literacy or mathematics or social studies in matched sessions. Instruction was conducted in 15-minute sessions from November through mid-April. Posttests on patterning,…

Poor sleep is thought to interfere with children's learning and academic achievement (AA). However, existing research and theory indicate there are factors that may mitigate the academic risk associated with poor sleep. The purpose of this study was to examine the moderating role of children's effortful control (EC) on the relation between sleep…

Childhood socioeconomic status (SES) predicts executive function (EF), but fundamental aspects of this relation remain unknown: the developmental course of the SES disparity, its continued sensitivity to SES changes during that course, and the features of childhood experience responsible for the SES-EF relation. Regarding course, early disparities…

Past research suggests robust positive associations between household socioeconomic status and children's early cognitive development in Western countries. Relatively little is known about these relations in low-income country settings characterized by economic adversity, high prevalence of malnutrition and infectious disease, and relatively lower…
