Age has often been considered a major, if not the primary, factor determining success in learning a second or foreign language. Children are generally considered capable of acquiring a new language rapidly and with little effort, whereas adults are believed to be doomed to failure. Although older learners are indeed less likely than young children to master an L2, a close examination of studies relating age to language acquisition reveals that age differences reflect differences in the situation of learning rather than in capacity to learn. They do not demonstrate any constraint on the possibility that adults can become highly proficient, even nativelike, speakers of L2s. Researchers, in other words, have often committed the same blunders as members of the general public: misinterpretation of the facts relating to speed of acquisition, misattribution of age differences in language abilities to neurobiological factors, and, most notably, a misemphasis on poor adult learners and an underemphasis on adults who master L2s to nativelike levels. By clarifying these misconceptions, we hope this article will lead to a better understanding of L2 learning and, in turn, better approaches to L2 teaching.
Studying lexical diversity in bilingual children with autism spectrum disorders (ASD) can contribute important information to our understanding of language development in this diverse population. In this exploratory study, lexical comprehension and production and overall language skills were investigated in 14 English-Chinese bilingual and 14 English monolingual preschool-age children with ASD. Results indicated that both groups had equivalent scores on all but one measure of language and vocabulary, including English production vocabulary, conceptual production vocabulary, and vocabulary comprehension. When comparing the two languages of bilingual participants, there were no significant differences in production vocabulary size or vocabulary comprehension scores. The results provide evidence that bilingual English-Chinese preschool-age children with ASD have the capacity to function successfully as bilinguals.
This study aimed to gather information from school- and clinic-based professionals about their practices and opinions pertaining to the provision of bilingual supports to students with developmental disabilities. Using an online survey, data were collected in six socio-culturally and linguistically diverse locations across four countries: the United States, Canada, the United Kingdom, and the Netherlands. In total, 361 surveys were included in the analysis from respondents who were primarily teachers and speech-language pathologists working in schools, daycares/preschools, or community-based clinics. The overall picture that emerged from the data reflected a disconnection between practice and opinion. In general, respondents believed that children with both mild and severe disabilities are capable of learning a second language, although their opinions were more neutral for the latter group. However, children with both mild and severe disabilities who spoke only a minority language at home had less access to services for second language learners than did their typically developing peers, although respondents agreed that such services should be more available. Regardless of clinical group, children who lived in homes where a minority language was spoken were often exposed to, assessed in, and treated in the majority language only; again, respondents generally disagreed with these practices. Finally, second language classes were less available to children in the two disability groups compared to typically developing bilingual children, with general agreement that the opportunity to acquire a second language should be more available, especially to those with mild disabilities. Although the results indicate that there is a considerable gap between current practices and professional opinions, professionals appear to be more supportive of bilingual educational opportunities for these populations than was suggested by previous research.
A number of studies have shown that bilingual children have an advantage when performing on phonological awareness tasks, particularly in their stronger language. Little research has been done to date, examining the effects of bilingualism on both languages of bilingual children. In this study Mandarin-English bilingual children's performance on phonological awareness tests was compared with that of Mandarin monolingual children and English monolingual children. The Mandarin-English bilinguals performed better than English monolinguals on the Elision and Blending sub-tests of the Comprehensive Test of Phonological Processing (CTOPP). Similarly, Mandarin-English bilinguals also performed better than their Mandarin monolingual counterparts on most of the experimental Mandarin phonological awareness tasks. The results from the study are discussed in terms of the effects of bilingualism on phonological awareness in both languages of bilingual children. Further clinical and educational implications of these results are also discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
