Human language and cognition do not develop independently of each other but are intricately intertwined in various ways. This contribution presents the interplay between linguistic and cognitive abilities of learners at the individual level and relates them to the level of external contextual factors in social and educational environments. In…

Children from language minority homes reach school age with variable dual language skills. Cluster analysis identified four bilingual profiles among 126 U.S.-born, 5-year-old Spanish-English bilinguals. The profiles differed on two dimensions: language balance and total language knowledge. Balance varied primarily as a function of indicators of…

This study sought to contribute to the growing literature on third and subsequent language learning by establishing whether bilingualism has an effect on ability to learn a subsequent language, as indicated by a measure of language aptitude, the Defense Language Aptitude Battery (DLAB). Test results were obtained for 142 diplomatic officers in the…

Research on second language acquisition (SLA) has identified language aptitude and age of onset (AO), i.e., the age at which learners are first meaningfully exposed to the L2, as robust predictors of rate of classroom language learning and level of ultimate L2 attainment in naturalistic settings, respectively. It is not surprising, therefore, that…

Among the new and multiple demands from contemporary society, framed in a global context of constant changes and advances, one of the most outstanding needs in recent years is the early acquisition of a second language. It is commonly known that, when starting the process of learning a second language or L2 being in adulthood, the results are not…

Investigators of first language attrition, early bilingualism and child second language learning have found common ground on a number of important points. The present review of the research will show that the study of unevenness in the early development of two languages reveals more clearly how the critical problems for future research on…

This dissertation aims to understand the maturational and non-maturational aspects of early bilingualism and language attrition in heritage speakers who have acquired their L1 incompletely in childhood. The study highlights the influential role of age and input dynamics in early L1 development, where the timing of reduction in L1 input and the…

Purpose: The present study investigated the effects of selected measures of language experience (parent-reported estimates of frequency of output and language use) and language ability (parent-reported language proficiency and mean length of utterance in words) on the segmental accuracy of Spanish- and English-speaking bilingual children. Method:…

Measures of productivity and sentence organization are useful metrics for quantifying language development and language impairments in monolingual and bilingual children. It is not yet known what measures within and across languages are most informative when evaluating the language skills of bilingual children. The purpose of this study was to…

While language aptitude has been investigated actively within second language research, there is a current dearth of research on the effects of aptitude in cases of attrition. The aim of the present investigation was to explore the role of language aptitude for L1 proficiency in speakers who experienced a break with their L1 setting prior to…

Reports research on the communicative behavior of a hearing child whose parents communicated with him, from birth, in both signs and words. The child's expressive ability accelerated in both modalities and this is possibly attributable to the addition of the signed component. (PJM)

Childhood bilingualism may develop toward a steady state of balanced competence in 2 languages or toward an imbalanced competence in which one of the child's languages begins to undergo attrition or early stabilization. In child second language learning an analogous distinction is often drawn between additive and subtractive bilingualism. This…

To investigate the actual and possible roles of parents in the development of preschoolers' bilingual ability, this study examined the home environments and bilingual ability of Singapore preschoolers. A total of 378 children, aged 5 and 6 years, were divided into 2 groups and individually interviewed. Children in one group began the interview in…

This book provides a practical introduction to questions about bilingualism. It is for parents and teachers who are themselves bilingual, for monolinguals who want to know more, for those with some intuitive understanding of bilingual situations and for those who are starting from the very beginning. The book poses questions that people often ask…
