Purpose: Children who are deaf or hard of hearing (D/HH) are at increased risk for neurocognitive delays, which can have cascading effects on development. Associations between neurocognition and the content of parental language--specifically the use of mental state vocabulary--have been observed in typically hearing (TH) children. This study…

Research Findings: Using two groups of dual language learners (DLLs), the current study examined links between two developmental constructs closely linked to school readiness: the home language environment (HLE) and executive function (EF). In a sample of 90 children (age range = 38-70 months, 59% girls) from either Mexican American (MA, N = 46)…

Language switch costs have been explored less in receptive tasks than in productive tasks, and previous studies have produced mixed findings with regard to switch cost symmetry and the relationship of switch costs to executive function. To address these unresolved gaps, one hundred Chinese-English bilingual adults completed a bilingual lexical…

Research has yet to reach a definitive consensus on whether or how bilingualism confers benefits on Executive Function (EF): numerous studies show an EF advantage for bilinguals over monolinguals, while others indicate no significant differences. These inconsistencies demonstrate that the mechanisms behind a potential bilingualism-to-EF…

Research Findings: A substantial body of research has demonstrated social and academic benefits of sociodramatic play (SDP) for young children. However, substantially less research has explored the factors related to increased amounts of SDP occurring during free play, an activity time that comprises the greatest portion of the daily schedule in…

Research Findings: The present study examined patterns of longitudinal associations between inhibitory control (IC) and early academic skills during the preschool and kindergarten years. Using data from the Head Start Family and Child Experiences Survey Cohort 2009 (FACES 2009) (N = 939), a national data set of predominantly low-income children…

How does multilingualism affect thinking and behavior? Recent findings demonstrate that multilingualism influences executive functioning, as well as personality traits and dimensions. Concordant outcomes show that multilingual individuals are more likely to be successful at inhibiting certain types of conduct (e.g., impulsivity) than monolinguals.…

The purpose of this study was to examine the relationship between school-based kindergarten transition practices and student achievement and executive functioning using recent, nationally representative data from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11. The analysis employed 3-level hierarchical linear models and…

Children vary in their ability to use language in social contexts and this has important consequences for wellbeing. We review studies that test whether individual differences in pragmatic skill are associated with formal language ability, mentalizing, and executive functions in both typical and atypical development. The strongest and most…

This longitudinal study examined pragmatic language in boys and girls with Down syndrome (DS) at up to three time points, using parent report, standardized and direct assessments. We also explored relationships among theory of mind, executive function, nonverbal mental age, receptive and expressive vocabulary, grammatical complexity, and pragmatic…

Using an epidemiological sample (N = 1,117) and a prospective longitudinal design, this study tested the direct and indirect effects of preverbal and verbal communication (15 months to 3 years) on executive function (EF) at age 4 years. Results indicated that whereas gestures (15 months), as well as language (2 and 3 years), were correlated with…

In recent decades, the share of ethnically and linguistically diverse children enrolled in schools in the United States has exponentially increased. Despite the growing representation of ethnic minority and dual language learner (DLL) children, there is persistent evidence of early vocabulary gaps between low-income and DLL children and their…
