A quarter of a century has passed since complex dynamic systems theory was proposed as an alternative paradigm to rethink and reexamine some of the main questions and phenomena in applied linguistics and language learning. In this article, we report a scoping review of the heterogenous body of research adopting this framework. We analyzed 158…

Complex Dynamic Systems Theory (CDST), an instantiation in applied linguistics of complexity epistemology that transcends disciplinary boundaries, has gained much traction and momentum over the last decade, finding expressions in a fast-growing number of empirical second language developmental studies. However, the literature, while rapidly…

Evidence for the role of procedural memory in second language (L2) acquisition has emerged in our field. However, little is known about the reliability and validity of the procedural memory measures used in this research. The present study (N = 119) examined the reliability and the convergent and discriminant validity of three assessments that…

The traditional implicit learning literature has focused primarily on the abstraction of statistical regularities in form-form connections. More attention has been recently directed toward the implicit learning of form-meaning connections, which might be crucial in the acquisition of natural languages. The current article reports evidence for…

This article examines how changes in linguistic theory affect the debate between the fundamental difference hypothesis and the access-to-Universal Grammar (UG) approach to SLA. With a focus on subjacency (Chomsky, 1973), a principle of UG that places constraints on "wh"-movement and that has frequently been taken as a test case for verifying…

Foreign language learning contrasts with native language development in two key respects: It is unreliable and it is nonconvergent. At the same time, it is clear that foreign languages are languages. The fundamental difference hypothesis (FDH) was introduced as a way to account for the general characteristics of foreign language learning. The FDH…

A fundamental question in the study of second language (L2) fluency is the extent to which temporal characteristics of speakers' first language (L1) productions predict the same characteristics in the L2. A close relationship between a speaker's L1 and L2 temporal characteristics would suggest that fluency is governed by an underlying trait. This…

Whereas most research in SLA assumes the relationship between the first language (L1) and the second language (L2) to be unidirectional, this study investigates the possibility of a bidirectional relationship. We examine the domain of manner of motion, in which monolingual Japanese and English speakers differ both in speech and gesture. Parallel…

Discusses the motivation for Universal Grammar (UG), as assumed in the principles and parameters framework of generative grammar (Chomsky, 1981), focusing on the logical problem of first-language acquisition and the potential role of UG in second-language acquisition. Recent experimental research regarding the second-language status of the…

Considers some of the claims for learnability principles that have been proposed within the first language context and the problems associated with their application to second language acquisition. A discussion of the ways research on learnability in second language acquisition can contribute to further development of learnability theory is…

It is shown that supplying positive evidence in the second-language (L2) classroom does not necessarily trigger the appropriate L2 value of a parameter of Universal Grammar. The verb movement parameter of Pollock is investigated; results suggest that positive evidence does not preempt the first-language parameter. (27 references) (Author/LB)

Discusses the minimal requirements that any serious theory of language acquisition must meet, including the particular properties of the human language processor and linguistic and nonlinguistic input. A review of literature regarding the role of Universal Grammar in second-language acquisition suggests alternative theories to investigate for…

The production of unstressed vowels in English by early and late Korean- and Japanese-English bilinguals was investigated. All groups were nativelike in having a lower fundamental frequency for unstressed as opposed to stressed vowels. Both Korean groups made less of an intensity difference between unstressed and stressed vowels than the native…

Researches the extent to which attrition is the reverse of the language acquisition process by studying the German case system. The Linguistic Hypothesis (based on the notion of regression) and the Cognitive Hypothesis (based on the assumption that there is a tendency to establish one-to-one correspondence between function and morphological case…

The study of SLA, as is true for much social science research, aims broadly at answering questions of causality--for instance, "Is one learning context more likely than another to promote gains in second language learning?" Context-of-learning research in the study of SLA, however, often involves observational, rather than experimental,…
