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…

The current study investigates the impact of the teachers' societal dominant language use within a weak version of translanguaging in early heritage language education. We explored five preschool teachers' use of English, the dominant majority language, in Tamil heritage language classes in Singapore and examined its impact on 33 children's…

This study investigates the effects of native language experience and phonetic properties on the discrimination of labial-velar versus labial and velar contrasts, as well as voicing contrasts in labials, velars, and labial-velars. Research indicates that phonological perceptions are influenced by native language experience and the specific…

This study explored Chinese heritage language learners' prior Mandarin experiences and their current Mandarin-learning experiences to reveal factors that influence their motivation and intention to continue or discontinue their Mandarin coursework. Using a Grounded Theory approach, we conducted demographic surveys and semi-structured interviews…

For many children in Flanders, Belgium, the language of instruction is not their first language. Allowing children to use their heritage languages in the classroom has been argued to have functional and socioemotional benefits. In two exploratory studies, we introduced a multilingual task in four classrooms across three linguistically and socially…

The Topic Hypothesis posits that Chinese language learners progress through a developmental sequence comprising five stages (Gao, 2009; Wang, 2011), which includes the Object-Subject-Verb (OSV) structure at stage 4 and the ba-construct at stage 5. According to this hypothesis, learners typically master the OSV structure before acquiring the…

This study investigated three key issues in heritage language (HL) research. Previous research shows HL speakers have an advantage on oral production tasks compared to L2 speakers who instead perform better on written tasks. Furthermore, both L2 and HL speakers are claimed to have a "yes-bias" towards retaining ungrammaticality in GJTs.…

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…

Code-switching has been studied from different approaches, ranging from syntactical, sociolinguistic, psycholinguistic, phonetically and many others. One key area that phonetic studies have explore has been the production of VOT in Spanish-English bilinguals due to the differences across the languages. To understand how bilinguals co-activate…

This dissertation examines heritage language learners of Spanish enrolled in university Spanish courses, focusing on their strategic use of suprasegmental speech features in two speaking tasks. The research investigates attitudes' influence on heritage language learners' speech production in different task types. Participants engaged in two…

Upon acquiring or learning another language, cross-linguistic influence (CLI) is an inevitable phenomenon with which a bilingual speaker lives. One key aspect of CLI is its bidirectionality, flowing between both the first (L1) and second languages (L2) mutually affecting each other. However, investigations of L1 CLI on L2 have dominated previous…

This study explored second language (L2) competence in discontinuous discursive formulaic sequences, namely Chinese correlative connectives (CCCs; e.g. yinwei . . . suy 'because . . . so'), in relation to the determinants of formulaic sequence acquisition by scrutinizing L2 Chinese learners' performance on two controlled tasks. Mixed-effects…

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…

Arabic emphasis refers to the production of consonants resulting from a primary constriction in the dental or alveolar region and a secondary constriction in the back of the vocal tract, recognized as 'Emphatic.' These have contrastive consonants produced in the dental or alveolar region, recognized as 'Plain.' The existing research on emphasis in…

To this day, there are only a few studies that have used a controlled instructional intervention on specific linguistic structures to investigate if language instruction is beneficial for heritage learners (HLs), in the same way it is for second (L2) language learners, and more research in this area is rapidly needed (Bowles, 2018). The results…
