Literature on early language acquisition has observed that age of onset of acquisition (AoA) is relevant for certain grammatical phenomena. Simultaneous bilinguals receive regular and extensive exposure to two languages from birth (Müller, 2009), whereas sequential child learners get in extensive contact to L[subscript B] once the L[subscript A]…

Verbal morphology has been identified as a particularly vulnerable domain for adult heritage speakers (HSs) of Spanish, especially when it involves the selection of subjunctive mood. A minimal amount is known, however, about the potential effects of the variability associated with these forms on the acquisition of related epiphenomena, such as the…

Assessing vocabulary knowledge is an important part of establishing language proficiency in bilingual children. The crosslinguistic lexical tasks (CLTs) provide a framework for testing vocabulary development in three-to-six year-olds using a standard procedure and comparable items for multiple languages. This study describes the development of the…

As critical approaches to Heritage Language (HL) instruction are increasingly more widespread, it is now more pertinent than ever to conduct research on Spanish linguistic variation that reveals systematicity and refutes hegemonic notions of 'incorrectness'. This variationist study examines the use and distribution of the Preterite and Imperfect…

The Interface Hypothesis proposes that the pragmatic-discursive interface with syntax is more vulnerable to crosslinguistic influence than the syntactic-semantic interface [Tsimpli, Ianthi, and Antonella Sorace. 2006. "Differentiating Interfaces: L2 Performance in Syntax- Semantics and Syntax-Discourse Phenomena." In Proceedings of the…

This longitudinal study examined the development of narrative micro- and macrostructure in Japanese-English bilingual returnee children. Returnees are children of immigrant families who move to a foreign country, spending a significant portion of their formative developmental years in the foreign majority language context before returning to their…

Heritage language (HL) speakers seem to diverge from monolingual speakers in the acquisition of syntax-discourse interface phenomena. However, most of the studies reporting this finding do not make any distinction between different types of syntax-discourse interface structures. Therefore, it is an open question whether these structures are…

Cross-linguistically, monolingual children produce target-like inflected verbs much earlier than they can reliably distinguish between singular and plural subject-verb agreement morphology in comprehension (i.e. Johnson, V., J. de Villiers, and H. Seymour. 2005. "Agreement Without Understanding? The Case of Third Person Singular /s/."…

This is a longitudinal and naturalistic study of the bilingual acquisition of English and Turkish languages simultaneously by a 28-month old Turkish infant. The emphasis is on empirical findings collected from a two-year period of observations beginning from the subject's birth and lasting until his 28-month old linguistic status. The study is…

This study contributes to current trends of heritage speaker bilingualism research by examining the syntax of so-called Spanish dative-experiencer predicates ("gustar"-like verbs). Building on previous findings (e.g., Silva-Corvalán 1994; Toribio and Nye 2006), it is hypothesized that Spanish heritage speakers can project an optional…

In this article the way bilinguals handle differing semantic categories in their two languages will be investigated. Drawing on bilingual data from multilingual speakers of Romansh as well as from speakers of (Swiss) German, the tensions that emerge from "conflicting habits" in the two languages are analyzed in the semantic domain of…

Background: The phonological and morphosyntactic structures of English and Mandarin contrast maximally and an increasing number of bilinguals speak these two languages. Speech and language therapists need to understand bilingual development for children speaking these languages in order reliably to assess and provide intervention for this…

This study investigates the use of the Spanish subjunctive in bilingual children with and without specific language impairments (SLI). Using an elicitation task, we examine: (i) the potential of the subjunctive as a grammatical marker of SLI in Spanish-English bilingual children, (ii) the extent to which degree of bilingualism affects performance,…

Lexical development in first language (L1) Turkish and second language (L2) German in two- to three-year-old children was examined, using parental vocabulary checklists in Turkish and in German. Children showed strong Turkish dominance in the number of lexical items they produced, which was due to the more frequent exposure to Turkish and higher…

Cognates have served as a useful tool for investigating the bilingual lexicon in many studies, but very little research has been carried out on different types of cognates, specifically, partial cognates and their role in cross-linguistic effect. The present study examines cognate effect in the speech production and acceptability judgment of two…
