The burgeoning field of third language (L3) acquisition has increasingly focused on intermediate stages of language development, aiming to establish the groundwork for comprehensive models of L3 learning that encompass the entire developmental sequence. This article underscores the importance of a robust epistemological foundation, advocating for…

Unlike with the typically developing population, non-typically developing individuals, especially those with intellectual disabilities, have usually been recommended to learn and use only one language, despite perhaps coming from bilingual families or living in multilingual environments. This common practice, however, is not backed by empirical…

Spanish native speakers are known to pronounce onset /sC/ clusters in English with a prothetic vowel, as in "esport" for sport, due to their native language phonotactic constraints. We assessed whether accurate production of e.g. "spi" instead of "espi" was related to accurate perceptual discrimination of this…

Success in mathematics contributes to children's future career and lifelong financial security. There have been reports that dual-language education conveys academic advantages in mathematics achievement, although there is debate. This study aimed to investigate whether dual-language education benefits children's mathematics achievement and…

Despite frequent reliance on teacher and parent ratings of children's behavior for multi-informant assessment, agreement between teachers' and parents' ratings is low. This study examined the predictive utility of teacher and parent ratings for children's self-regulatory outcomes (i.e., executive function, continuous performance task) in four…

Success in mathematics contributes to children's future career and lifelong financial security. There have been reports that dual-language education conveys academic advantages in mathematics achievement, although there is debate. This study aimed to investigate whether dual-language education benefits children's mathematics achievement and…

This study centered on emergent bilingual (EB) students with specific reading comprehension deficits (S-RCD), that is, with poor reading comprehension despite solid word identification skills. The participants were 209 students in Grades 2 to 4, including both EBs and English monolinguals (EMs) with and without S-RCD. Mean comparisons indicated…

This study centered on Dual Language Learners (DLLs) with specific reading comprehension deficits (S-RCD), that is, with poor reading comprehension despite solid word identification skills. The participants were 209 students in Grades 2-4, including both DLLs and English Monolinguals (EMs) with and without S-RCD. Mean comparisons indicated that…

Despite much research examining whether bilingual individuals demonstrate superior executive function (EF) skills compared to monolinguals, the purported bilingual advantage remains controversial. One potential reason for discrepant findings across studies examining the bilingual advantage is the difficulty in matching monolingual and bilingual…

Purpose: There is conflicting evidence regarding effects of bilingualism on inhibition, and the mechanisms that might underlie the effects remain unclear. A prominent account views additional demands on structural language use in bilinguals as being at the root of bilingual effects on inhibition. In this study, we tested the novel hypothesis that…

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…

Georgia's Pre-K Longitudinal Study followed a statewide sample of 1,169 children who attended Georgia's Pre-K Program in 2013-14 through their 4th grade year in 2018-19. The study was conducted by researchers at the Frank Porter Graham (FPG) Child Development Institute at the University of North Carolina at Chapel Hill. The following summary…

Research Findings: This study examined the heterogeneity in Spanish-speaking children's (N = 117; M age = 53 months; SD = 5 months; 57% boys) vocabulary and letter-word skills in English and Spanish after one year of preschool and the extent to which early self-regulation abilities (i.e., executive function and effortful control) were associated…

Given concerns about the reading achievement of Dual Language Learners (DLLs) in comparison to English Monolinguals (EMs), this study examined individual difference variables contributing to English reading comprehension growth in Spanish-speaking DLLs and their EM counterparts in Grades 1-4. The participants, who included 578 DLLs and 412 EMs,…

The purpose of this evaluation study was to examine children's longitudinal academic and social outcomes associated with attendance in Georgia's Pre-K Program and to examine the quality of the classrooms attended. This report covers pre-k to 4th grade outcomes collected between the 2013-2014 and 2018-2019 school years as well as a sub-study…
