Bilingualism: Language and Cognition最新文献

The present paper investigates whether school-aged French-English bilingual children’s implicit and explicit knowledge of article use is affected by cross-linguistic influence (CLI) during online and offline sentence comprehension. The studies focus on the encoding of plural and mass nouns in specific and generic contexts. We also explore whether individual measures of oral proficiency, language exposure and age play a role in the children’s performance. Forty-three 8-to-10-year-old French-English bilingual children took part in a Self-Paced Reading task, a Grammaticality Judgement task and a Cloze test in their two languages. Overall, CLI was observed across tasks in English and French. These findings suggest that CLI can be bi-directional and tap into school-aged bilinguals’ implicit and explicit representations during sentence comprehension and production. The data also makes a new contribution to our understanding of the relative amount of language exposure, oral proficiency and age on CLI.

Verbal fluency data for semantic (animals, fruit and vegetables and objects) and formal fluency (X [Chi], Σ [Sigma] Α [Alpha]) were collected from 32 L1Greek-L2English late bilingual speakers and 32 Greek monolinguals. The verbal fluency task has been used in both language attrition and bilingualism studies. Language attrition studies, which mostly employ only the semantic task, show that bilinguals perform worse than monolinguals. In bilingualism studies, which employ both the semantic and formal tasks, we find greater variance and the results are mixed (bilinguals perform similarly, better or poorly compared to monolinguals). In our study, we investigated quantitative measures (number of correct responses) and strategic processes (clustering, switching). In the quantitative measures, monolinguals outperformed bilinguals in both tasks with the difference being more pronounced in the semantic task. In clustering, both groups behaved similarly, while in switching monolinguals performed better than bilinguals. The implications of these results are discussed.

Whether speaking two or more languages (multilingualism) or dialects of one language (bidialectalism) affect executive function (EF) is controversial. Theoretically, these effects may depend on at least two conditions. First, the multilingual and bidialectal characteristics; particularly, (second) language proficiency and the sociolinguistic context of language use (e.g., Green & Abutalebi, 2013). Second, the EF aspects examined; specifically, recent accounts of the locus of the multilingual effect propose a general EF effect rather than an impact on specific processes (Bialystok, 2017). We compared 52 “monolingual” (with limited additional-language/dialect experience), 79 bidialectal and 50 multilingual young adults in the diglossic context of Cyprus, where bidialectalism is widespread and Cypriot and Standard Greek are used in different everyday situations. Three EF processes were examined via seven tasks: inhibition, switching and working memory (Miyake et al., 2000). We found better multilingual and bidialectal performance in overall EF, an effect moderated by high (second) language proficiency.

Phoneme discrimination is believed to be less accurate in non-native languages compared to native ones. What remains unclear is whether differences in pre-attentive phonological processing emerge between the first foreign language (L2) and additional ones (L3/Ln), and whether they might be influenced by the acquisition setting (formal vs. naturalistic). We conducted an event-related brain potential oddball study with native Polish learners of English (L2) and Norwegian (L3/Ln). The results revealed a graded amplitude of the mismatch negativity (MMN) effect, which was largest in L1, smaller in L2, and smallest in L3/Ln. Considering the previously obtained results for naturalistic/mixed learners with the same language combination, we believe that the acquisition setting is an important factor influencing the perception of phonemic contrasts. In the naturalistic group, no difference was observed between L1 and L2, while the instructed group exhibited more fine-grained distinctions between all tested languages.

Cross-linguistic interactions are the hallmark of bilingual development. Theoretical perspectives highlight the key role of cross-linguistic distances and language structure in literacy development. Despite the strong theoretical assumptions, the impact of such bilingualism factors in heritage-language speakers remains elusive given high variability in children's heritage-language experiences. A longitudinal inquiry of heritage-language learners of structurally distinct languages – Spanish–English and Chinese–English bilinguals (N = 181, Mage = 7.57, measured 1.5 years apart) aimed to fill this gap. Spanish–English bilinguals showed stronger associations between morphological awareness skills across their two languages, across time, likely reflecting cross-linguistic similarities in vocabulary and lexical morphology between Spanish and English. Chinese–English bilinguals, however, showed stronger associations between morphological and word reading skills in English, likely reflecting the critical role of morphology in spoken and written Chinese word structure. The findings inform theories of literacy by uncovering the mechanisms by which bilingualism factors influence child literacy development.
