Research in the field of third language acquisition has consistently identified two key factors which have an effect on the ways in which the two known languages may influence the acquisition of a third. These factors are language distance (typology) and language status (more specifically, second language, L2, or non-native language status). To…

Purpose: The contemporary practices of delivering speech, language, and hearing services in schools reflect palpable gains in professional sensitivity to linguistic and cultural diversity. Method: This article reviews the dominant research themes on the oral language of African American preschoolers who contribute to such diversity in the United…

This dissertation presents results from a series of experiments investigating adult learning of an artificial language and the effects that input frequency (high vs. low token frequency), frequency distribution (skewed vs. balanced), presentation mode (structured vs. scrambled), and first language (English vs. Japanese) have on such learning.…

It has been widely shown that infants and adults are capable of using only prosodic information to discriminate between languages. However, it remains unclear which aspects of prosody, either rhythm or intonation, listeners attend to for language discrimination. Previous researchers have suggested that rhythm, the duration and timing of speech…

The present study explores knowledge of Spanish grammatical gender in both comprehension and production by heritage language speakers and second language (L2) learners, with native Spanish speakers as a baseline. Most L2 research has tended to interpret morphosyntactic variability in interlanguage production, such as errors in gender agreement, as…

This article reviews research on working memory (WM) and its use in second language (L2) acquisition research. Recent developments in the model and issues surrounding the operationalization of the construct itself are presented, followed by a discussion of various methods of measuring WM. These methods include word and digit span tasks, reading,…

This article addresses the role of previously acquired languages in the acquisition of a third language (L3) in two experimental studies on object expression in Brazilian Portuguese (BP). Participants were English-speaking learners of BP as L3 with knowledge of Spanish as a second language (L2) and Spanish-speaking learners of BP with knowledge of…

Although there have been many studies examining the acquisition of grammar in Japanese as a second language (L2) (e.g., Nagatomo, 1993; Noda, Sakoda, Shibuya, & Kobayashi, 2001), discourse analysis research on the L2 acquisition of Japanese discourse structure is still in its infancy. This study examines how L2 learners organize their spoken…

In sign language studies, it is generally assumed that a sign can be divided into several phases in time (preparation, stroke, and retraction) and that the stroke contains all of the necessary information. However, this has not been tested empirically. In order to learn where the information truly resides, we present an experiment that…

When addressing infants, many adults adopt a particular type of speech, known as infant-directed speech (IDS). IDS is characterized by exaggerated intonation, as well as reduced speech rate, shorter utterance duration, and grammatical simplification. It is commonly asserted that IDS serves in part to facilitate language learning. Although…

The conclusion begins with an analysis of the common thread that ties the papers included in this special issue together. The collection hinges on an analysis of issues of language and power in diverse contexts, seen in a perspective "a la" Jim Cummins. Included in the Conclusion is a discussion of how the papers in this collection illustrate or…

The Second Language Studies (SLS) Program was established in 2005 with the express purpose of providing "a firm foundation in the field of Second Language Acquisition and its application to current second language research and teaching" (http://sls.msu.edu). Under the leadership of Professor Susan Gass, the program has grown to include…

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…

Since language is a biological trait, it is necessary to investigate its evolution, development, and functions, along with the mechanisms that have been set aside, and are now recruited, for its acquisition and use. It is argued here that progress toward each of these goals can be facilitated by new programs of research, carried out within a new…

Speech priming tasks are frequently used to delineate stages in the speech process such as lexical retrieval and motor programming. These tasks, often measured in reaction time (RT), require fast and accurate responses, reflecting maximized participant performance, to result in robust priming effects. Encouraging speed and accuracy in responding…
