Previous research has consistently demonstrated that false-belief (FB) understanding correlates with and predicts metalinguistic ability in preschoolers. Surprisingly, however, there is scant evidence on the question of whether this relation persists at later ages. The present cross-sectional study sought to fill this gap by examining the…

The current study describes the development and validation of a novel scale (BILEX) designed to assess young bilingual children's receptive vocabulary in both languages, their conceptual vocabulary, and translational equivalents. BILEX was developed to facilitate the assessment of vocabulary size for both of the children's languages within one…

Cognates are known to facilitate second language acquisition and use, as learners tend to assign to a new L2 word the meaning of a similar L1 word. Consequently, for L2 tests that rely largely on lexical items, performance may prove inflated for examinees whose L1 shares many cognates with the language being tested. This article examines the…

Purpose: The aim of this study was to investigate language growth in individuals with fragile X syndrome (FXS) from early childhood to adolescence and the influence of maternal responsivity on language growth. Method: We conducted a longitudinal analysis of language development in 55 youths (44 males, 11 females) with FXS. Data collection spanned…

Purpose: Elementary-age dual language learners (DLLs) from Spanish-speaking homes in the United States are often characterized as at risk for low vocabulary in both Spanish and English. This longitudinal study examined conceptually scored receptive and expressive vocabulary development among DLLs from Spanish-speaking, low-income homes and…

Purpose: The purpose of this study was to understand how joint attention and sensory-regulatory features are related in early childhood and predict language and social-communication outcomes in preschool in order to build mechanistic theories that can inform early intervention directed at improving these outcomes. Method: Cross-lagged panel…

In recent years, the widespread growth of mobile-assisted language learning using apps has made English vocabulary learning increasingly accessible. This study investigated students' perceptions of a vocabulary learning app developed by the researcher as a tool to help them to improve their L2 receptive vocabulary. The app, containing 20 levels,…

Current literacy assessments are focused on a single mode of meaning-making (reading and writing, whether oral or written) and assume that literacy and language are 'fixed systems'-- comprised of discrete skills that can be taught and measured in isolation. This validation and privileging of a single mode of assessment are most culpable in…

Measures of decoding and oral language have been shown to predict early reading comprehension across a wide variety of languages, though the timeframe and strength of the predictions vary by orthographic depth. This study is the first to examine predictors of early reading in Vietnamese, a transparent orthography of Romanized letters and…

This article examines factors that promote active multilingualism. For this purpose, the "Peabody Picture Vocabulary Test" was used with 48 children. Their results were linked to a parental questionnaire designed to evaluate the children's linguistic input in their immediate environment. The study shows that, besides a minimum amount of…

In this multi-year study, we taught English/Language Arts teachers of students with learning disabilities in middle school to incorporate 15 min of daily vocabulary activities with students in their intact special education English/Language Arts classes. During Year 1, teachers taught 48 words to their sixth grade students, who learned and…

Learning collocations poses difficulties for foreign language learners despite their importance for fluency in the target language. Collocation learning and teaching should therefore be an integral part of foreign language instruction. With a focus on the receptive knowledge of collocations, this 5-week-long pretest/posttest quasi-experimental…

Research Findings: Promoting inhibitory control in preschoolers could increase the likelihood of positive developmental trajectories. Nevertheless, to date only a limited number of studies have focused on inhibitory control training, reporting mixed results. To examine the efficacy and the transfer effects of the training on preschoolers, seven…

This research analyzes data collected by the Young Lives project on childhood poverty. It addresses the effect of socio-demographic, individual, and linguistic variables -- focusing on the latter -- on reading comprehension in Spanish by 502 Peruvian Quechua-Spanish bilingual children aged 8 years. The regression model tested explained 46% of the…

Executive function (EF) skills play a crucial role in young children's academic and social-emotional development. Given that factors associated with poverty can compromise the development of EF skills, it is vital to continue to examine what factors help predict and support EF skills in children from at-risk backgrounds. Using a sample of Head…
