Research on input processing and processing instruction has often employed a scoring method known as trials to criterion to observe the effects of instruction that emerge during training. Despite its common use in this research (see Fernández, 2021) this metric has never been evaluated critically. The present study first discusses several…

This article has two main goals. The first is to summarize and comment on the current state of affairs of generative approaches to SLA (GenSLA), 35 years into its history. This discussion brings the readership of SSLA up to date on the questions driving GenSLA agendas and clears up misconceptions about what GenSLA does and does not endeavor to…

In this article, we challenge the notion that aptitude--operationalized as grammatical sensitivity as measured by the Words in Sentences section of the Modern Language Aptitude Test--is central to adult second language (L2) acquisition. We present the findings of a study on the acquisition of two properties of Japanese, head-final word order and…

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…

Second language (L2) researchers are becoming more interested in both L2 learners' knowledge of the target language and how that knowledge is put to use during real-time language processing. Researchers are therefore beginning to see the importance of combining traditional L2 research methods with those that capture the moment-by-moment…

In the previous 20 years, more than 60 studies have been carried out within the input and interaction approach to SLA (Long, 2007; Mackey 2012), many of which have found positive associations between different types of recasts and the learning of a range of linguistic forms for a number of different second languages (L2s), in different learning…

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…

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…

This article provides a comprehensive synthesis of research on language attrition to date, with a view to establishing a theoretically sound basis for future research in the domain of second language (L2) attrition. We identify the variables that must be tracked in populations who experience language loss, and we develop a general model for the…

The role of explicit information (EI) as an independent variable in instructed SLA is largely underresearched. Using the framework of processing instruction, however, a series of offline studies has found no effect for EI (e.g., Benati, 2004; Sanz & Morgan-Short, 2004; VanPatten & Oikkenon, 1996). Fernandez (2008) presented two online experiments…

Researchers have claimed that recasts might be ambiguous as feedback. Because recasts serve a dual function, as both feedback and conversational response, learners might not always interpret them as feedback (e.g., Lyster & Ranta, 1997). This study explores how learners interpret recasts they notice (as responses to content, negative evidence,…

Responds to Ellis (2002), which suggests the statistical structure of the linguistic environment is a crucial and relatively neglected variable in language learning. This approach makes three assumptions about cognition and language learning that are not universally shared. Describes a distributed, instance-based approach that retains key features…

Discusses frequency effects in language acquisition. Provides an example of how frequency may relate to grammatical judgments of nonnative speakers acquisition of multiple wh-questions. (Author/VWL)

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…
