Purpose: Spontaneous speech tasks are critically important for characterizing spoken language production deficits in aphasia and for assessing the impact of therapy. The utility of such tasks arises from the complex interaction of linguistic demands (word retrieval, sentence formulation, articulation). However, this complexity also makes…

Much language teaching still depends on assumptions established in the nineteenth century, namely the priority of speech over writing, the maximal use of the target language in the classroom, the rejection of explicit explanation of grammar and the use of the native speaker as the role model for the student. None of these assumptions are supported…

Contending with talker variability has been found to lead to processing costs but also benefits by focusing learners on invariant properties of the signal, indicating that talker variability acts as a desirable difficulty. That is, talker variability may lead to initial costs followed by long-term benefits for retention and generalization. Adult…

Purpose: Although conversational recast treatment is generally efficacious, there are many ways in which the individual components of the treatment can be delivered. Some of these are known to enhance treatment, others appear to interfere with learning, and still others appear to have no impact at all. This study tests the potential effect of…

This paper investigates the difference between the production of grammatical determiners and lexical determiners in the production of adjective-noun phrases (NPs) in Danish. Models of sentence processing (Garrett in "Psychology of learning and motivation," Academic press, New York, pp 133-177, 1975; Bock in "J Mem Lang"…

Many people want to learn a foreign language, but issues of time, convenience and cost mean that classes are often insufficient for learners, and increasingly learners are supplementing or replacing their classroom learning with online learning. The majority of existing online language learning systems use the traditional grammar-translation…

The positive effects of shared book reading on vocabulary and reading development are well attested (e.g., Bus, van Ijzendoorn, & Pellegrini, 1995). However, the role of shared book reading in GRAMMATICAL DEVELOPMENT remains unclear. In this study, we conducted a construction-based analysis of caregivers' child-directed speech during shared…

This study examines the effects of form-focused instruction (FFI) on the acquisition of subject-verb inversion word order in declarative sentences in German. A group of U.S. college students who participated in a semester-long study abroad program in Germany and were comparable in terms of preprogram oral proficiency levels and accuracy scores in…

The growth of English into a lingua franca has inevitably created linguistic deviations and innovations in the use of English. These emerging uses that result from the needs and preferences of speakers whose mother tongues are all different can be broadly identified as lexico-grammatical and pronunciation features and they compose one of the main…

Purpose: This study investigated methodological and theoretical aspects of using mean length of utterance (MLU) and its alternatives in cross-linguistic research and, in particular, its applicability to Russian--a language with a rich system of grammatical and derivational morphemes. Method: We collected audio recordings of spontaneous speech…

The current project examined whether and to what degree age of acquisition (AOA), defined as the first intensive exposure to a second language (L2) environment, can be predictive of the end state of postpubertal L2 oral proficiency attainment. Data were collected from 88 experienced Japanese learners of English and two groups of 20 baseline…

This paper investigates the development of discourse referencing in spoken Cantonese of fifteen deaf/hard-of-hearing children studying in a sign bilingual and co-enrolment education programme in a mainstream setting in Hong Kong. A comparison of their elicited narratives with those of the hearing children and adults shows that, despite a delay in…

This study investigates the developmental trajectory of relative clauses (RCs) in Mandarin-learning children's speech. We analyze the spontaneous production of RCs by four monolingual Mandarin-learning children (0;11 to 3;5) and their input from a longitudinal naturalistic speech corpus (Min, 1994). The results reveal that in terms of the…

Whereas studies show that comprehensible output facilitates L2 learning, hypothesis testing has received little attention in Second Language Acquisition (SLA). Following Shehadeh (2003), we focus on hypothesis testing episodes (HTEs) in which learners initiate repair of their own speech in interaction. In the context of a one-way information gap…

This paper introduces a Dialog-Based Computer-Assisted second-Language Learning (DB-CALL) system using semantic and grammar correctness evaluations and the results of its experiment. While the system dialogues with English learners about a given topic, it automatically evaluates the grammar and content properness of their English utterances, then…
