In this article we compare five groups of learners acquiring Dutch gender as marked on determiners and adjectival inflection. Groups of L1 (first language) children and L1-SLI (first-language specific-language-impairment) children are compared to three Turkish-Dutch L2 (second language) groups: adult L2, child L2 and child L2-SLI. Overall, our…

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)

Examines the connection between empirical studies of interaction involving second-language learners and the specific claims of Krashen's Input Hypothesis, as modified by Chaudron, White, and Swain. (36 references) (GLR)

The notion that a sensitive period exists for language acquisition has gained support from several studies. This study demonstrates that there exist differing periods of heightened sensitivity for certain aspects of the target language, periods before and after in which the learner is less sensitive to the relevant input. (Author/JL)

A comparison of the error profiles of monolingual (child L1) learners of Dutch, Moroccan children (child L2) and Moroccan adults (adult L2) learning Dutch as their L2 shows that participants in all groups massively overgeneralize [-neuter] articles to [+neuter] contexts. In all groups, the reverse gender mistake infrequently occurs. Gender…

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…

In a series of studies children show increasing mastery of irregular plural forms (such as "mice") simply by producing erroneous over-regularized versions of them (such as "mouses"). We explain this phenomenon in terms of successive approximation in imitation: Children over-regularize early in acquisition because the representations of frequent,…

Proposes a research agenda that makes acquisitional research central to the study of comprehensible output (CO). Looks at the context in which the CO hypothesis was proposed--that of looking beyond comprehensible input as a condition for second language acquisition. (Author/VWL)

Responds to comments made regarding an earlier article written by the author on processing instruction in second language learning. (Author/VWL)

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,…

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.…

Reviews processing (PI) instruction, outlines a model of input processing, describes the nature of PI, and discusses research on it to date. (Author/VWL)

Responds to VanPatten's update of the findings for processing instruction. Questions the explanatory adequacy of the model of input processing that VanPatten proposed and that underpins his pedagogic proposals. Questions the validity of the limited-capacity, single-resource model of attention proposed for second language learning. (Author/VWL)
