The Null Subject Parameter (NSP) has long been considered pertinent to Second Language Acquisition (SLA) studies, especially when the native language (NL) and target language (TL) have different NSP settings. The study aimed to investigate whether seventy English L2 learners in Puerto Rico who were native Spanish speakers transferred their L1…

This paper provides fresh insights on how PIs (Polarity Items) in non-veridical contexts (questions and conditionals) are represented in the grammar of multilingual learners of Catalan at different stages of development. It explores how this non-native grammatical system interacts with other previously acquired systems of negation and the implicit…

The purpose of this study was to assess the use of an adapted picture description task described by Eisenberg and Guo to explore the morphosyntactic error patterns of English-Spanish preschool simultaneous bilingual learners. Language samples were collected from 28 bilingual preschool children aged 3 to 5 years. Language samples were elicited in…

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:…

Referential expressions (REs) have been investigated in L2 English but to date there is no single study that systematically and simultaneously analyzes the development and acquisition of the multiple factors that constrain the choice of REs in natural discourse production. We investigate L1 Spanish-L2 English learners across three proficiency…

Recent approaches to the "that"-trace phenomenon in English include syntactic analyses based on the principle of Anti-locality and a sentence production analysis based on the Principle of End Weight. These analyses have many similarities, but they differ in their predictions for second language (L2) speakers. In an Anti-locality…

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…

Translanguaging pedagogy is gaining widespread recognition as an approach that recognizes and builds on multilingual students' linguistic resources. Research on translanguaging pedagogy has predominantly focused on classroom language practices, while studies on the design and enactment of translanguaged instruction are limited. This pilot study…

Purpose: This study aimed to examine changes in English and Spanish morphosyntactic standardized scores over time in bilingual children. Method: One hundred bilingual children participated in this longitudinal study. The average age of the children at the beginning of the study was 5;11 (years; months). A subset of the participants was identified…

Purpose: This study examined the relationship between utterance length, syntactic complexity, and the probability of making an error at the utterance level. Method: The participants in this study included 830 Spanish-speaking first graders who were learning English at school. Story retells in both Spanish and English were collected from all…

Purpose: There is limited research on the writing of young Spanish-English bilinguals and their writing in both languages. In the current study, we addressed whether written syntax features differed by language (English and Spanish) and varied as a function of grade level, English learner status, and instructional program (dual or English…

English ditransitive verbs show a complex alternation between the double object construction (DOC, (1)) and prepositional object datives (POD, (2)). This dissertation examines the acquisition, representation, and learnability of the dative alternation among L2 English learners, presenting experimental data from participants with L1 backgrounds of…

This study attempts to explain a systematic phenomenon that has been described in interlanguage grammars crosslinguistically: Null-Prep, which consists of omitting the obligatory preposition in certain movement constructions. We propose that Null-Prep is not related to lack of knowledge of "wh"-movement, as previously assumed, but to…
