The aim of this study was to investigate deficits in planning ability using an adapted version of the Modified Six Elements Test, from the Behavioral Assessment of the Dysexecutive Syndrome--BADS [Wilson, B. A., Alderman, N., Burgess, P. W., Emslie, H., & Evans, J. J. (1996). "Behavioural Assessment of the Dysexecutive Syndrome…

This study evaluates the empirical merits of a multilevel model of English language proficiency among immigrants. The model represents a synthesis of Blau's theory of intergroup relations and the human capital model. Hypotheses derived from the model were tested using multilevel ordinal logistic analysis with individual and aggregate data from…

We investigated the associations between Boston naming and the animal fluency tests and cortical atrophy in 19 probable AD and 5 multiple domain amnestic mild cognitive impairment patients who later converted to AD. We applied a surface-based computational anatomy technique to MRI scans of the brain and then used linear regression models to detect…

This dissertation compares the phonetic and phonological features of adult non-speakers' productions of words in an endangered Native American language, Oregon Northern Paiute (also known, and hereafter referred to, as Numu), to productions by fluent speakers. The purpose of this comparison is two-fold. The first purpose is to examine the…

Grounded in research and practical expertise, this volume helps K-6 teachers skillfully support all of their English language learners (ELLs)--from a single student to an entire classroom. Ideas for teaching ELLs across different grade and proficiency levels include ways to link instruction to students' lived experiences, use a variety of…

This dissertation provides an automated scoring method of speech fluency for second language learners of English (L2 learners) based that uses speech recognition technology. Non-standard pronunciation, frequent disfluencies, faulty grammar, and inappropriate lexical choices are crucial characteristics of L2 learners' speech. Due to the ease of…

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…

This work reports on the construction of a rated database of spontaneous speech produced by second language (L2) learners of English. Spontaneous speech was collected from 28 L2 speakers representing six language backgrounds and five different proficiency levels. Speech was elicited using formats similar to that of the TOEFL iBT and the Speaking…

Parents with Limited English Proficiency (LEP) may find it difficult to become involved in their children's education due to their lack of English proficiency. The present study examined the effects of using audio prompting to assist mothers with LEP in teaching their preschool children English vocabulary. Mothers were trained to tutor their…

Experts throughout the United States tell us that teachers must support the home language development of all young children. Karen Nemeth emphasizes the important role early childhood educators play in ensuring that young dual language learners retain skills in their home language while building new English language skills. She invites educators…

By centralizing the issue of test fairness in language proficiency assessments, this study responds to a call by researchers for developing greater social responsibility in the language testing agenda. As inquiries into language attitude and psychology indicate, there is an underlying uncertainty pertaining to the validity of test use and score…

In Sociocultural Theory, mediations in second language learning include (1) mediation by others (2) mediation by self (3) and mediation by artifacts, which incorporates brilliant insights for EFL contexts (Lantolf, 2000). Putting these ideas in a task-based method, the present study aimed at examining the contribution of scaffolding and private…

This study examined adult age differences on five tests of divergent thinking: associational fluency, expressional fluency, ideational fluency, word fluency, and consequences. Our hypothesis was that young adults ( M = 20.53, n = 60) would score higher than old adults (M = 72.10, n = 60) under standard timed test conditions, but old adults would…

The study reported in this paper is an investigation of the nature of speaking proficiency in English as a second language in the context of a larger project to develop a rating scale for a new international test of English for Academic Purposes, TOEFL iBT (Brown et al. 2005). We report on a large-scale study of the relationship between detailed…

This article presents a series of studies focusing on L2 production and processing of adjective-noun collocations (e.g., "social services"). In Study 1, 810 adjective-noun collocations were extracted from 31 essays written by Russian learners of English. About half of these collocations appeared frequently in the British National Corpus (BNC);…
