A pervasive question in second language (L2) research is whether L2 learners can acquire parameterized functional features that are not instantiated in their first language (L1). While some researchers have argued for a representational deficit (e.g., Clahsen & Muysken, 1989; Hawkins & Chan, 1997), claiming that L2 learners' competence is…

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 contributes to current trends of heritage speaker bilingualism research by examining the syntax of so-called Spanish dative-experiencer predicates ("gustar"-like verbs). Building on previous findings (e.g., Silva-Corvalán 1994; Toribio and Nye 2006), it is hypothesized that Spanish heritage speakers can project an optional…

This article reports an empirical study investigating L2 acquisition of the Mandarin Chinese "shì…de" cleft construction by adult English-speaking learners within the framework of the Feature Reassembly Hypothesis (Lardiere, 2009). A Sentence Completion task, an interpretation task, two Acceptability Judgement tasks, and a felicity…

This exploratory study investigated whether joint attention through eye gaze was predictive of second language (L2) speakers' responses to recasts. L2 English learners (N = 20) carried out communicative tasks with research assistants who provided feedback in response to non-targetlike (non-TL) forms. Their interaction was audio-recorded and their…

This study presents the results from a computer-assisted language learning (CALL) system of Runyakitara (RU_CALL). The major objective was to provide an electronic language learning environment that can enable learners with mother tongue deficiencies to enhance their knowledge of grammar and acquire writing skills in Runyakitara. The system…

L2 learners' problems with English articles have been linked to learners' L1 and their access to universal semantic features (e.g., definiteness and specificity). Studies suggest that L2 adults rely on their L1 knowledge, while child L2 learners rely more on their access to semantic universals. The present study investigates whether child L2…

This article investigates spoken productions of complex questions with long-distance wh-movement in the L2 English of speakers whose first language is (Canadian) French or Bulgarian. Long-distance wh-movement is of interest as it can be argued that it poses difficulty in acquisition due to its syntactic complexity and related high processing load.…

This article reports a study that sought to determine whether non-native sentence comprehension can show sensitivity to two different types of Spanish case marking. Sensitivity to case violations was generally more robust with indirect objects in ditransitive constructions than with differential object marking of animate direct objects, even among…

The present study examines and compares the extent to which advanced L2 learners of Spanish and Spanish heritage speakers acquire the syntactic and semantic properties that regulate the grammatical representation of double complementizer questions in Spanish, a CP-related structure not present in English. Results from an aural sentence completion…

This study investigates whether adult second language learners' online processing of "wh"-dependencies is constrained by island constraints on movement. Proficiency-matched Spanish and Korean learners of English completed a grammaticality judgment task and a stop-making-sense task designed to examine their knowledge of the relative…

Implicit and explicit knowledge of the second language (L2) are two central constructs in the field of second language acquisition (SLA). In recent years, there has been a renewed interest in obtaining valid and reliable measures of L2 learners' implicit and explicit knowledge (e.g., Bowles, 2011; R. Ellis, 2005). The purpose of the present study…

Language interference is one of the factors that affect language learning by many learners of second and third languages. In Zambia, the impact of language interference on the learners of French requires closer attention. Our literature review shows that few studies have looked at the impact of interference from Zambian languages on the learners…

The present article provides an exploration of ultimate attainment in second language (L2) and its limitations. It is argued that the question of maturational constraints can best be investigated when the reference population is bilingual and exposed on a regular basis to varieties of their first language (L1) that show cross-linguistic influence.…

This study examined the second language (L2) development of adult learners of Spanish at three levels of proficiency during and after a semester of instruction. A fundamental goal was to identify cognitive and psychosocial individual differences (IDs) that can explain between-learner variation over time in order to expand our understanding of the…
