Usage-based theory has proposed that learning of linguistic constructions is facilitated by input that contains few high-frequency exemplars, in what is known as a skewed (or Zipfian) input distribution. Early empirical work provided support to this idea, but subsequent L2 research has provided mixed findings. However, previous approaches have not…

Usage-based theories hold that mental representation of language is shaped by a lifetime of usage. Both input to which first language (L1) and second language (L2) users are exposed and their own language production affect their construction learning and entrenchment. The present study investigates L2 users' knowledge of two…

In this study, we propose a hypothesis that domain-general auditory processing, a perceptual anchor of L1 acquisition, can serve as the foundation of successful post-pubertal L2 learning. This hypothesis was tested with 139 post-pubertal L2 immersion learners by linking individual differences in auditory discrimination across multiple acoustic…

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 fundamental difference hypothesis (FDH), as formulated by Bley-Vroman (1990), claims that SLA tends to be nonconvergent because domain-specific linguistic mechanisms available in early childhood cannot be used for language learning in adulthood: Instead, second language (L2) learners deploy domain-general problem solving skills. I claim that…

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)

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.…

The concept of input to the language learner is examined with reference to some current theorizing about language processing and the idea of modular systems of knowledge. It is argued that exposure to a second language engages the learner in a whole battery of different processing mechanisms. (21 references) (Author/LB)

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)

The hypothesis defended is that negative data and explicit data result in a type of knowledge that is not to be equated with linguistic competence. The specific claim is that only positive data can effect the construction of an interlanguage grammar comparable to the knowledge system characterizing the results of first-language acquisition. (60…

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…

Attempts to determine whether or not explicit information given to second-language learners receiving processing instruction is responsible for the beneficial effects of instruction. Results indicate that these beneficial effects derived from the structured input activities and not from the explicit explanation provided to learners. (22…

Stable nonnative varieties of English acquired and used in the absence of native English input can diverge systematically from native varieties over time (Cheshire, 1991; Kachru, 1983; Platt, Weber, & Ho, 1984). Focusing on Indian English article use, this study asks the following question: If divergence is indeed occurring, do new features…

Addresses a number of issues that have to do with nature of mental representation of an interlanguage grammar. Major focus is on necessity of positing some sort of hierarchical constituent structure to account for what second-language learners do in their phonology. The purpose is to show the utility of invoking a theory of abstract phonological…

Examined the influence of input and interactional modifications on second-language acquisition, assigning 41 learners of Japanese to 1 of 3 experimental groups: (1) unmodified input with no interaction; (2) premodified input with no interaction; and (3) unmodified input with the chance for negotiated input. Results indicated that comprehension was…
