There is presently a lively debate in second language (L2) acquisition research as to whether (adult) learners can acquire linguistic phenomena located at the interface between syntax and other modules, such as semantics, pragmatics, and lexical semantics, in contrast to phenomena that are purely syntactic in nature. For some researchers, the…

This study examined the event-related potentials (ERPs) elicited by focus processing among first language (L1) speakers and second language (L2) learners of French. Participants read wh-questions containing explicit focus marking, followed by responses instantiating contrastive and informational focus. We hypothesized that L2 proficiency would…

This study investigated the effect of the first language (L1) on the visual word recognition of inflected nouns in second language (L2) Finnish by native Russian and Chinese speakers. Case inflection is common in Russian and in Finnish but nonexistent in Chinese. Several models have been posited to describe L2 morphological processing. The unified…

Evidence of learning following incidental exposure has been found for aspects of nonnative syntax in adults (Rebuschat & Williams, 2006, 2012; Williams & Kuribara, 2008). However, little research has tested delayed effects of learning under an incidental condition or moved beyond word order. This study investigated learning of third…

Adult learners have persistent difficulty processing second language (L2) inflectional morphology. We investigate associative learning explanations that involve the blocking of later experienced cues by earlier learned ones in the first language (L1; i.e., transfer) and the L2 (i.e., proficiency). Sagarra (2008) and Ellis and Sagarra (2010b) found…

A large body of research has shown that suffixes--both inflectional and derivational--can be primed with adult native speakers, which informs our understanding of storage and access to morphology in mature systems. However, this line of research has not yet been conducted from an acquisition perspective: Little is known about whether or not…

With Russian as the target language, a proof of concept study was undertaken to determine whether it is possible to identify linguistic features, control over which is implicated in progress on the Interagency Linguistic Roundtable (ILR) proficiency scale, thereby better to inform the instructional process. Following its development in an…

Research has consistently shown there is a negative correlation between age of onset (AO) of acquisition and ultimate attainment (UA) of either pronunciation or grammar in a second language (L2). A few studies have indeed reported nativelike behavior in some postpuberty learners with respect to either phonetics/phonology or morphosyntax, a result…

The purpose of this article is to offer contextual linguistic explanations for morphosyntactic deviances (MSDs) in high-level second language (L2) French (30 nonnative speakers vs. 10 native speakers). It is hypothesized that the distribution of formulaic sequences (FSs) and the complexity of information structure will influence the occurrence of…

The current study investigates the limited attainment of adult language acquisition in terms of an associative learning phenomenon whereby earlier learned cues attentionally block those that are experienced later. Short- and long-term blocking are demonstrated in experimental investigations of learned attention in the acquisition of temporal…

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…

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…

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…

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…
