Much research has been conducted in adult second language learning through interaction, but knowledge about the child language learner has remained scarce. To address social language development in middle childhood, the article presents a longitudinal case study concerning a nine-year-old L1 Russian-speaking learner of Finnish. The data consist of…

Errors with "be", whether omission (e.g., "John happy") or overuse (i.e., "be"-insertion; e.g., "John is love Mary"), have received particular attention in L2 acquisition studies exploring L1 transfer. This study investigates such errors in the context of L3 acquisition, focusing on L1 transfer. L1-Chinese…

We present the case study of MB--a bilingual child with Down syndrome (DS) who speaks Russian (first language [L1]) and English (second language [L2]) and has learned to read in two different alphabets with different symbol systems. We demonstrate that, in terms of oral language, MB is as proficient in Russian as English, with a mild advantage for…

In order to reach far in the work for sustainable development, communication in foreign languages prior to strategic decisions is required from international partners. In this communication English has become the lingua franca. Even though the use of EFL (English as a foreign language) is widely spread, it is clear that in some geographical…

This study looks at the relationship between L1 (Russian) attrition and L1 reading ability in Russian-English-speaking bilingual children. Ten Russian-English bilingual children and 10 adults participated in this study. Nine out of 10 children participants were born in the US and used L1 as their primary language of interaction within the family,…

This paper examines article use in the L2-English of adult and child speakers of Russian, an article-less language. In earlier work on articles in adult L2-English, Ionin, Ko and Wexler (2004) proposed that speakers of article-less L1s fluctuate between dividing English articles on the basis of definiteness vs. specificity, as a result of direct…

In this paper we argue that investigation of third language (L3) acquisition by adults and children provides essential new insights about the language learning process that neither the study of first language (L1) nor second language (L2) acquisition alone can provide. The focus of this paper concerns the role the learner's L1 plays in succeeding…

Examines how second-language knowledge is integrated with the first, noting elements of native language development that are most resistant to influence from second languages and those that are most permeable. Discusses how the process of integration and influence can be universal or different depending on the language, using data from native…
