The traditional implicit learning literature has focused primarily on the abstraction of statistical regularities in form-form connections. More attention has been recently directed toward the implicit learning of form-meaning connections, which might be crucial in the acquisition of natural languages. The current article reports evidence for…

In response to new theoretical claims and inconclusive empirical findings regarding relative clauses in East Asian languages, this study examined the factors relevant to relative clause production by Korean heritage speakers. Gap position (subject vs. object), animacy (plus or minus animate), and the topicality of head nouns (plus or minus…

This review examines whether similarity between the first language (L1) and second language (L2) influences the (morpho)syntactic processing of the L2, using both neural location and temporal processing information. Results from functional magnetic resonance imaging (fMRI) and event-related potential (ERP) studies show that nonnative speakers can…

Morphological variability and the source of these errors have been intensely debated in SLA. A recurrent finding is that postpuberty second language (L2) learners often omit or use the wrong affix for nominal and verbal inflections in oral production but less so in written tasks. According to the missing surface inflection hypothesis, L2 learners…

The position of antecedent strategy (Carminati, 2002) claims that speakers of null-subject languages prefer to resolve intrasentential anaphora by linking pro to an antecedent in the specifier of the inflection phrase and the overt pronoun to an antecedent lower in the clause. The present study has two aims: (a) to determine whether adult early…

It is widely recognized that the processor has a key role to play in creating and strengthening the mapping between form and meaning that is integral to language use. Adopting an emergentist approach to heritage language acquisition, the current study considers the extent to which the operation of the processor can contribute to an account of what…

Although claims about explicit and implicit language knowledge are central to many debates in SLA, little research has been dedicated to measuring the two knowledge types (R. Ellis, 2004, 2005). The purpose of this study was to validate the use of the battery of tests reported in Ellis (2005) to measure implicit and explicit language knowledge.…

This study presents an investigation of oral narratives collected from heritage Egyptian and Palestinian Arabic speakers living in the United States. The focus is on a number of syntactic and morphological features in their production, such as word order, use of null subjects, selection of prepositions, agreement, and possession. The degree of…

This study presents and analyzes the comprehension of relative clauses in child and adult speakers of Russian, comparing monolingual controls with Russian heritage speakers (HSs) who are English-dominant. Monolingual and bilingual children demonstrate full adultlike mastery of relative clauses. Adult HSs, however, are significantly different from…

The present study aims to sensitize SLA researchers to the importance of documenting and controlling for their participants' proficiency in the target language, with the goal of establishing more robust proficiency assessment standards in experimental research. First, this article presents a survey of recent (2000-2008) foreign and second-language…

Word association responses in first-language (L1) Spanish and second-language (L2) English were investigated by means of response latencies and types of associative response produced. The primary aims were to establish whether (a) some response types are produced more often or faster than others, (b) participants' L2 response time profiles mirror…

The present study is concerned with the upper limits of SLA--specifically, mastery of the syntax-discourse interface in successful endstate learners of second-language (L2) French (near-native speakers). Left dislocation (LD) is a syntactic means of structuring spoken French discourse by marking topic. Its use requires speakers to coordinate…

Improvement in second-language (L2) perception has been posited to occur early in L2 learning when the L2 vocabulary is still small, whereas a large L2 vocabulary curtails perceptual learning (the perceptual assimilation model for SLA [PAM-L2]; Best & Tyler, 2007). This proposition is extended by suggesting that early L2 lexical development…

Over the last 40 years, there have been successive attempts to define or refine a set of key concepts intended to guide theory and experimentation in SLA. These include "input," "intake," and "consciousness." This article tries to take these attempts a stage further by integrating the conceptualization of these notions into a larger…

The purpose of this study is to begin work toward a grammatical assessment measure that could bridge the gap between theoretical work on grammatical development, on the one hand, and tools such as the Michigan Test (which uses multiple-choice questions on vocabulary and grammar) or the American Council on the Teaching of Foreign Languages scale…
