Understanding the changes in our language abilities along the lifespan is a crucial step for understanding the aging process both in normal and in abnormal circumstances. Besides controlled experimental tasks, it is equally crucial to investigate language in unconstrained conversation. I present an information-theoretical analysis of a corpus of…

This study adopted Ambridge's research paradigm to examine the effects of entrenchment, preemption, and verb semantics in second language (L2) acquisition of English "un-" prefixation. Three groups of Chinese learners of English (second- and fourth-year English majors and teachers of English) rated the acceptability of 48 "un-"…

Collaborative text reconstruction tasks such as dictogloss have been suggested as effective second language (L2) learning tasks that promote meaningful interaction between learners and their awareness of L2 target grammatical structures. However, it should be noted that the effect of pair interaction on the final product may differ depending on…

Most studies on task-based language learning focus on the oral performance of advanced level learners of English as a second language (ESL), while little research examines the written performance of beginning language learners in non-ESL contexts. This exploratory study aims to address this gap, by examining the effect of pre-writing tasks on…

Evidence of learning following incidental exposure has been found for aspects of nonnative syntax in adults (Rebuschat & Williams, 2006, 2012; Williams & Kuribara, 2008). However, little research has tested delayed effects of learning under an incidental condition or moved beyond word order. This study investigated learning of third…

One of the intricate properties of second language acquisition is that some types of grammatical feature appear to be acquired easily and in a native-like way, while others remain persistently difficult. There is much evidence related to the issue in the current empirical studies, and the issue raises an important explanatory problem for a theory…

This study used quantitative analyses complemented by the retrospective data obtained through a stimulated recall procedure to address three interrelated issues: (a) whether second language learners use online planning opportunities to carefully plan their speech to enhance the quality of the language they produce, (b) what kinds of self-repair…

In this study we investigate the linguistic performance of a school age French-Greek simultaneous bilingual boy with specific language impairment (SLI) on the production of subject-verb agreement, object clitic pronouns and wh-questions. In addition, we compare his performance on these linguistic structures with that of two French-Greek bilingual…

Assessments developed and field tested for the mainstream student population may not be accessible for students with disabilities (SWDs) as a result of the impact of extraneous variables, including cognitive features, such as depth of knowledge required, grammatical and lexical complexity, lexical density, and textual/visual features. This study…

This paper reports a case study of the nature and extent of progress in speaking skills made by a group of upper intermediate instructed learners, and also assessors' perceptions of that progress. Initial and final interview data were analysed using several measures of Grammatical and Lexical Complexity, Language Accuracy and Fluency. These…

The 2001 reauthorization of the "Elementary and Secondary Education Act (ESEA)," represented a turning point in federal policy for the education of English Learners (ELs) in U.S. public schools. At the center of the changes in the 2001 reauthorization of the "ESEA" lie the English language proficiency (ELP) standards. These ELP…

Current approaches to assessing agrammatism use data from restricted contexts, such as picture description and story telling tasks. There is evidence in the conversation analysis literature to suggest that conversational grammar may differ markedly from the grammar of such elicited language samples. The disparity between conversational and test…

The role of grammatical knowledge in inferencing word meaning has not received proper attention in L2 research. Addressing this issue, the present paper provides research-based and introspective think-aloud data to examine the contribution of grammatical knowledge to inferencing the meaning of unknown words. It addresses (a) the effects of…

This article presents findings from a year-long study of how intermediate second language (L2) learners of German (English first language) used case markings, word order, and semantic information when comprehending individual German sentences. The results showed that the learners relied on word order and semantic information, but did not…

The present paper looks at the growing population of Russian heritage speakers from a linguistic and psycholinguistic perspective. The study attempts to clarify further the notion of heritage language by comparing the linguistic performance of heritage speakers with that of monolinguals and second language learners. The amount of exposure to…
