The congruency effect--that is, faster and more accurate processing of congruent multiword units, has been demonstrated in multiple studies. It is still unclear, however, what its underlying mechanism is, and how congruency may interact with other factors. Using an acceptability judgement task, this study examined the congruency effect in…

This study is a replication and extension of Morgan-Short et al.'s (2018) investigation into the role of attention in input processing by L1-Polish learners of L2-Spanish, with proficiency and language of assessment explored as two key methodological factors. Our aims were twofold: to investigate learners' comprehension in different conditions…

Although retrieval of lexical forms is a prerequisite for language production, research of L2 vocabulary learning has focused much more on meanings and form-meaning mappings than on development of detailed, accessible mental representations of forms. This is particularly true with respect to multi-word items (MWIs). We report an experimental study…

In a visual world paradigm study, we manipulated gender congruence between a subject pronoun and two antecedents to investigate whether second language (L2) learners with a null subject first language (L1) acquire and process overt subject pronouns in a nonnull subject L2 in a nativelike way. We also investigated whether L2 speakers revise an…

This study investigated the effectiveness of providing L1 explicit information (EI) with practice for making more accurate and faster interpretations of L2 French "Imparfait" (IMP). Two treatments were investigated: (a) "L2-only," providing EI about the L2 with L2 interpretation practice, and (b) "L2+L1," providing…

This paper presents an experimental study of the rarely explored question of how input through instruction interacts with L2 acquisition at the level of modular linguistic knowledge. The investigation focuses on L2 knowledge of the English polarity item "any," whose properties are only partially covered by typical language-teaching…

This study investigated the influence of frequency effects on the processing of congruent (i.e., having an equivalent first language [L1] construction) collocations and incongruent (i.e., not having an equivalent L1 construction) collocations in a second language (L2). An acceptability judgment task was administered to native and advanced…

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…

The literature on corrective feedback (CF) that second language writers receive in response to their grammatical and lexical errors is plagued by controversies and conflicting findings about the merits of feedback. Although more recent studies suggest that CF is valuable (e.g., Bitchener, 2008; Sheen, 2007), it is still not clear whether direct or…

Responds to Ellis (2002), which focuses on frequency in language processing, language use, and language acquisition. Suggests his findings are consistent with those of second language acquisition researchers working with a variationist framework. Provides a brief overview of this research area and describes a psycholinguistic model of language…

In response to Ellis (2002), which focuses on frequency in language processing, language use, and language acquisition, this article argues in favor of a role for frequency in several areas of second language acquisition, including interactional input and output and speech processing. Also discusses areas where L2 acquisition appears to proceed…

An author reacts to a series of responses written in regard to an earlier article by the author on frequency in language processing, language use, and language acquisition. Addresses a number of issues raised in the responses and concludes by emphasizing that language acquisition is a process of dynamic emergence and learners' language is a…

Responds to Ellis (2002), which focuses on frequency in language processing, language use, and language acquisition. Contextualizes the frequency factor in terms of the evolution of second language acquisition (SLA) research. Suggests that although relevant and important, the frequency factor requires greater definition and qualification.…

Responds to an Ellis (2002), which focuses on frequency in language processing, language use, and language acquisition, Emphasizes the importance of placing frequency in an overarching theoretical framework of language acquisition. (Author/VWL)

A brief review of research on native language production precedes a critical discussion of recent second-language production research, focusing on native language research applications to second-language research, the relationship between second-language learning and production, and the various methodologies used to study such production.
