Goo and Mackey (this issue) outline several apparent design flaws in studies that have compared the impact of different types of corrective feedback (CF). Furthermore, they argue that SLA researchers should stop comparing recasts to other types of CF because they are inherently different kinds of phenomena. Our response to their article addresses…

There is a growing theoretical, empirical, and methodological debate in the SLA field as to whether unawareness plays a role during attention to or processing of new incoming second language (L2) data. Indeed, studies that have methodologically addressed the construct of unawareness in their research designs offer both empirical support (e.g.,…

This article reexamines Bley-Vroman's original (1990) and evolved fundamental difference hypothesis that argues that differences in path and endstate of first language acquisition and adult foreign language learning result from differences in the acquisition procedure (i.e., language faculty and cognitive strategies, respectively). The evolved…

Ellis's target article suggests that language processing is based on frequency and probabilistic knowledge and that language learning is implicit. These findings are consistent with those of SLA researchers working within a variationist framework (e.g., Tarone, 1985; Bayley & Preston, 1996). This paper provides a brief overview of this research…

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)

Discusses the role of frequency in phonological reduction. Argues that phonological alternations provide evidence for the size and nature of morphosyntactic chunks. The phonological shape of words provides evidence that categorization is not completely exemplar based, but rather involves some abstraction resembling the construction of a prototype.…

In response to Ellis (2002), which resurrects the notion that language acquisition consists of frequency-based abstraction of regularities from input, this article suggests Ellis ignores fundamental and well-known problems, including the poverty of the stimulus, cases of instantaneous acquisition, and evidence for innate knowledge. (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…

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…

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)

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 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…

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…

Examines Tomlin and Villa's (1994) analysis of attention and Leow's (1998) attempt to operationalize this model. Argues that Leow's efforts to provide empirical support for the model fall short of that goal. (Author/VWL)

Discusses key points raised in the articles in this special issue of the journal. Suggests progress is being made in using complementary theories of the role of lexical representation, prediction, and crosslinguistic variation to get a full picture of this complex area of lexico-morhposyntactic knowledge.
