Recent decades have seen an increase in research informing our understanding of the complex ways in which bilingual development is shaped by biological, cognitive, and behavioral factors. We investigate the predictors that shape, drive, and constrain the development of the first language (L1) of bilinguals, focusing on 92 Turkish-English bilingual…

This study aimed to test three competing hypotheses concerning the strength of the cross-language relationship in listening comprehension proficiency in emergent bilinguals: Cummins's developmental linguistic interdependence hypothesis, Proctor, August, Snow, and Barr's interdependence continuum hypothesis, and Goodrich, Lonigan, Kleuver, and…

This investigation aimed to provide insights into the controversial debate on the role that age at onset of bilingualism plays in human language capacity with a focus on what it entails for first language (L1) attrition. L1 performance of Turkish immigrants (n = 57) in the United Kingdom with age at onset ranging between 7 and 34 years was…

This study investigated the influence of cognitive ability on bilingual children's vocabulary development in both their languages. Sixty-nine bilingual immigrant children participated, with data collected at three annual intervals. At Time 1, the participants were 5 or 6 years old. Receptive vocabulary was tested in the minority (Turkish, Tarifit)…

The current study examined academic language (AL) input of mothers and teachers to 15 monolingual Dutch and 15 bilingual Turkish-Dutch 4- to 6-year-old children and its relationships with the children's language development. At two times, shared book reading was videotaped and analyzed for academic features: lexical diversity, syntactic…

Children who start formal education in a second language may experience slower vocabulary growth in that language and subsequently experience disadvantages in literacy acquisition. The current study asked whether lexical specificity training can stimulate bilingual children's phonological awareness, which is considered to be a precursor to…

The linguistic interdependence hypothesis states that the development of skills in a second language (L2) partly depends on the skill level in the first language (L1). It has been suggested that the theory lacked attention for differential interdependence. In this study we test what we call the hypothesis of context-dependent linguistic…

This study examined to what extent young second language (L2) learners showed morphological family size effects in L2 word recognition and whether the effects were grade-level related. Turkish-Dutch bilingual children (L2) and Dutch (first language, L1) children from second, fourth, and sixth grade performed a Dutch lexical decision task on words…

The purpose of this study was to identify factors that predict the first- and second-language proficiency of ethnic minority children at the age of six. Results of the study show two dimensions that underlie children's proficiency in either language: communicative skills versus cognitive/academic skills. (45 references) (JL)

Data on Dutch-Turkish language-mixing behavior of Turkish children growing up in The Netherlands are presented and analyzed. While functional characteristics of the children's language-mixing were compatible with models from earlier research, structural analysis suggests no universality of surface structure constraint rules for sentence-internal…

This study examined linguistic interdependence in 98 bilingual Turkish/Dutch children of Turkish background living in the Netherlands since birth, to determine whether language and literacy skills can be transferred from 1 language. The results indicated that, although the transference of lexicon and syntax skills was limited, pragmatic,…
