Greek and Spanish are two languages that display a similar subject distribution with unergative/unaccusative verbs, but different word orders with focused subjects (SV in Greek and VS in Spanish). Here we consider subject-verb word order in second language (L2) Greek and L2 Spanish in order to test the Interface Hypothesis (IH). To this end, we…

Constructivist approaches to language acquisition predict that form-function mappings are derived from distributional patterns in the input, and their contextual embedding. This requires a detailed analysis of the input, and the integration of information from different contingencies. Regarding the acquisition of morphology, it is shown which…

This study investigates the role of parental input quality on the acquisition of Greek as a heritage language in Western Canada. Focusing on subject use, we tested four groups of Greek speakers: monolingual children, heritage children, and the parents of each one of those groups. Participants completed an elicited production task designed to…

This article provides an overview of the research on morpho-syntactic challenges in Swedish-speaking children with developmental language disorder (DLD), compared with typically developing (TD) children learning Swedish as their first and second language (L1/L2). Children with DLD show vulnerabilities with verb finiteness, the possessive…

This study examined the linguistic and individual-level factors that render case marking a vulnerable domain in English-dominant Greek heritage children. We also investigated whether heritage language (HL) children can use case-marking cues to interpret (non-)canonical sentences in Greek similarly to their monolingual peers. A group of six- to…

This dissertation investigates how bilinguals use their two grammars to comprehend written intra-sentential codeswitches. I focus on adjective/noun constructions in Spanish and English where I manipulate the congruence of grammatical word order in the two languages across the codeswitch boundary. This allows me to test three codeswitching…

The study explores the extent to which the intrinsic complexity of relative clauses (RCs) and prior linguistic knowledge impact the acquisition of RCs by L2 learners. The study investigates the main sources of the erroneous and avoided types of English RCs produced by Persian-speaking learners of English at three proficiency levels. The data…

The present study examines the relative order of noun-adjective sequences within code-switched Determiner Phrases. Several hypotheses have been considered: is this a property defined by the determiner (Bartlett, 2013), the noun (Arnaus et al., 2012) or the adjective (Cantone & MacSwan, 2009)? Or on the contrary, if a carrier phrase is present,…

Previous studies suggest that age of acquisition affects the outcomes of learning, especially at the morphosyntactic level. Unknown is how syntactic development is affected by increased cognitive maturity and delayed language onset. The current paper studied the early syntactic development of adolescent first language learners by examining word…

Several studies used artificial language (AL) learning paradigms to investigate structural priming between languages in early phases of learning. The presence of such priming would indicate that these languages share syntactic representations. Muylle et al. (2020a) found similar priming of transitives and ditransitives between Dutch (SVO order)…

Grammar competition has been proposed as a model for second language (L2) acquisition. Variational Learning provides a framework within which to investigate the idea of grammar competition as the model requires a marriage of quantitative properties of the input with Universal Grammar. A diachronic variational model of grammar competition is…

Natural languages make prolific use of conventional constituent-ordering patterns to indicate "who did what to whom," yet the mechanisms through which these regularities arise are not well understood. A series of recent experiments demonstrates that, when prompted to express meanings through silent gesture, people bypass native language…

This study addresses the question of how the main factors related to input--including the environment in which children are exposed to both languages, the relative timing of the onset of the exposure to them and the amount of input--affect bilingual language acquisition at primary-school age. We examined the data of 42 German Polish bilinguals who…

Purpose: Diagnoses, assessments, and treatments, as well as social and language interventions, can be effective in identifying and interpreting specific linguistic features that present special challenges to the language abilities of individuals who are deaf and hard of hearing (DHH). This article reports on a study analyzing complex sentences and…

This study is aimed to re-examine the Interface Hypothesis via investigating the adult L2 acquisition of the word order variation of numeral classifier indefinites at the syntax-semantics and syntax-discourse interfaces in L2 Chinese. A computerized acceptability judgment task was administered to 41 advanced and intermediate adult Korean learners…
