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…

For more than a decade, research on heritage speakers' (HSs') mood selection has documented a high degree of variability in their interpretation and use of mood morphology in variable contexts. Most of the previous literature, however, has focused on late-acquired alternations, and often limited analyses to one form (i.e., subjunctive), making it…

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 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,…

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…

This dissertation compares the knowledge of Russian Verbal Aspect in two types of learners enrolled in college level Russian courses: foreign language learners of Russian whose native language is English and heritage language speakers of Russian whose dominant language at the time of study is English. Russian Aspect is known to be problematic both…
