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…

Possessive determiners (PDs) "his" and "her" are challenging for L2 learners to acquire, and this difficulty has been attributed to several factors, including negative L1 transfer effects (White et al., 2007). What researchers have not yet considered is how PDs are acquired by learners whose L1 predicts positive transfer…

Feature-based approaches to acquisition principally focus on second language (L2) learners' ability to perceive non-native consonants when the features required are either contrastively present or entirely absent from the first language (L1) grammar. As features may function contrastively or allophonically in the consonant and/or vowel systems of…

This text critically examines traditional methodologies for teaching grammar in the context of Portuguese as a Foreign Language (PFL). It proposes an alternative, eclectic approach, which can be used in any foreign language. Drawing on evidence from research and pedagogical practices, it highlights areas for improvement in current approaches, such…

The present dissertation brings together research on heritage language acquisition and bilingual education and makes inroads into the limited research on heritage language development in school-aged bilingual children. This study explores how bilingual education, patterns of exposure, and lexical frequency shape adolescent Spanish heritage…

This article reports on an experimental study on the acquisition of prepositional relative clauses in second language European Portuguese by Chinese native speakers. It focuses on the role of resumption, mandatory in prepositional relative clauses in Chinese (the native language of the learners) and non-conventional in European Portuguese (the…

Due to the relevance of the discussions on the use of counterbalance for content-based and form-focused second language instruction, the purpose of this study is to present some pedagogical strategies to teach and reinforce the correct use of articles, gender and number of nouns in Portuguese when teaching Language and Arts (first grade) and…

While formal L3 morphosyntactic acquisition research has focused on the roles of the L1 versus L2 during the L3 initial stages, we examine their roles during development. Specifically, we explore whether the L3 (here, Portuguese) revision process after non-facilitative transfer differs whether the initial L3 representation reflects the L1 or L2.…

Immersion students' language abilities are generally characterized by strong receptive skills (listening, reading) and less developed productive skills (speaking, writing) when compared with L1 speakers of the immersion language (e.g., Allen et al. 1990; Cummins 1998; Harley 1992). In this paper we report results from a six-month mixed-methods…

Considering the acquisition of past tense uses by L2 Spanish advanced learners with closely related L1s (French, Portuguese), this study attempts to identify factors associated with variability, such as negative transfer or interface integration. We report data on the acquisition, by adult L1 French and Portuguese learners at B2 and C1 CEFR…

Research on linguistic variation suggests that usage patterns are deeply embedded in native and non-native speakers' knowledge of grammar. This study explores the transfer of these variable sociolinguistic patterns at the initial stages of third language acquisition. We elicited narratives in Portuguese from two mirror-image groups of sequential…

This article proposes that second language learners can use indirect positive evidence (IPE) to acquire a phonological grammar that is a subset of their L1 grammar. IPE is evidence from errors in the learner's L1 made by native speakers of the learner's L2. It has been assumed that subset grammars may be acquired using direct or indirect negative…

This study tests native Brazilian Portuguese (BP) speakers of second language (L2) Spanish in the domain of phonologically null object pronouns. This is a worthwhile first language (L1)-L2 pairing given that these languages are historically and typologically related and both seemingly allow for object drop. Nevertheless, the underlying syntax of…

Language acquisition research frequently concerns itself with linguistic development and result of the acquisition process with respect to a first or subsequent language. For some, it seems tacitly assumed that a first language, once acquired, remains stable, regardless of exposure to and the acquisition of additional language(s) beyond the first…

This article addresses the role of previously acquired languages in the acquisition of a third language (L3) in two experimental studies on object expression in Brazilian Portuguese (BP). Participants were English-speaking learners of BP as L3 with knowledge of Spanish as a second language (L2) and Spanish-speaking learners of BP with knowledge of…
