Based on the bilingual children's and adults' code-switching (CS) dependency treebanks, this paper investigates the syntactic features and pragmatic functions of the Chinese-English bilingual children's CS and compares them with bilingual adults'. It is mainly found that (1) As to the bilingual children, the mixed sentences present the longest…

Previous research on the L1 acquisition of motion event expression suggests that mapping multiple semantic components onto syntactic units is associated with greater difficulties in verb-framed than in satellite-framed languages, because the former require more complex structures (using subordination). This study investigated the impact of this…

Purpose: This study examined the frequency, direction, and structural characteristics of code-switching (CS) during narratives by Spanish-English bilingual children with and without developmental language disorder (DLD) to determine whether children with DLD exhibit unique features in their CS that may inform clinical decision-making. Method:…

The research on language acquisition and retention has primarily focused on monolinguals and bilinguals, with comparatively few studies including trilinguals. To address this gap, the current study compares the acquisition and retention of a novel morphosyntactic rule in Spanish in twelve monolinguals, twelve bilinguals, and twelve trilinguals.…

Purpose: The purpose of this study was to find morphological markers with good diagnostic accuracy to identify developmental language disorders (DLD) in Spanish-English bilingual children. Method: The participants in this study included 66 Spanish-English bilingual children between the ages of 4;0 and 6;11 (years; months) with (n = 33) and without…

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…

The present study contributes to our understanding of the effects of age and type of linguistic input in the acquisition of Spanish as a second language in adulthood. I examine the Spanish syntax (word order) of three groups of speakers, monolingual Spanish speakers from Mexico and two bilingual English-Spanish speakers born and raised in the…

This study investigated cross-linguistic priming in six-year-old, balanced Spanish-English bilinguals (n = 60). We examined bilinguals' production of transitive forms in English (active, passive) after exposure to Spanish transitives (Study 1; M age = 6.2 years; SD = 0.3) and their production of transitive forms in Spanish (active, passive) after…

This paper shows the need to triangulate different approaches in Bilingualism and Second Language Acquisition (SLA) research to fully understand late bilinguals' interlanguage grammars. Methodologically, we show how experimental and corpus data can be (and should be) triangulated by reporting on a corpus study (Lozano and Mendikoetxea in…

This work investigates the acquisition of Spanish dative alternation (DA) in the production of English-Spanish bilingual and Spanish monolingual children. We explore whether "a/para"-datives and dative clitic doubled (DCLD) structures are syntactically derived from one another or, whether they are different structures. We also examine…

The present study examines the tradeoff between the on-line construction of modifier-noun gender agreement and verb-subject person/number agreement vs. the automatization and entrenchment of agreement, through the study of bilingual speakers of Spanish and the Afro-Colombian creole language Palenquero, whose lexicon is highly cognate with Spanish,…

Background: Grammatical morphology has been shown to be problematic for children with specific language impairment (SLI) or developmental language disorder (DLD). Most research on this topic comes from widely spoken languages, such as English. Despite Welsh being the most extensively spoken indigenous in the UK after English, and Wales being the…

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…

Mixed languages like Media Lengua incorporate grammar from one source language (here, Quichua) but lexicon from another (here, Spanish). Due to their linguistic profile, they provide a unique window into bilingual language usage and language representation. Drawing on sociolinguistic, structural and psycholinguistic perspectives, the current…

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…
