Purpose: This study was designed to (a) compare the speech fluency of school-age children who do and do not stutter (CWS and CWNS, respectively) within 2 standard diagnostic speaking contexts (conversation and narration) while also controlling for speaking topic, and (b) examine the extent to which children's performance on such discourse tasks is…

The purpose of this research was to firstly develop a protocol for video recording student group oral presentations, for later viewing and self-assessment by student group members. Secondly, evaluations of students' experiences of this process were undertaken to determine if this self-assessment method was a positive experience for them in gaining…

Concern for the impact of prenatal cocaine exposure (PCE) on human language development is based on observations of impaired performance on assessments of language skills in these children relative to non-exposed children. We investigated the effects of PCE on speech processing ability using event-related potentials (ERPs) among a sample of…

The present study examined the language development of children adopted from China to examine possible early age effects with respect to their use of complement clitics, lexical diversity and verb morphology. We focused on these aspects of French because they distinguish second language learners of French and native French-speaking children with…

Despite acknowledgement of the limited English vocabularies demonstrated by many language minority (LM) learners, few studies have identified skills that relate to variation in vocabulary growth in this population. This study investigated the concurrent development of morphological awareness (i.e., students' understanding of complex words as…

In this study, the Canadian English and French versions of the Problem-Solving Measure of the Programme for International Student Assessment 2003 were examined to investigate their degree of measurement comparability at the item- and test-levels. Three methods of differential item functioning (DIF) were compared: parametric and nonparametric item…

Research on language learning strategies (LLS) has pointed to a significant association at a general level between learners' gender and their choice of LLS. To explore this generality further, we conducted a study on gender and strategy use with Sri Lankan learners (N = 886) of English as a second language (ESL) in five different learning…

Forty-six Consumer Affairs (CA) internship supervisors were surveyed to identify critical knowledge and skills demonstrated by interns and to examine the importance of knowledge and skills needed in the workplace from the supervisors' perspectives.The knowledge and skills measured were identified through program goals. Results revealed that CA…

This case study explores the motivations for code switching (CS) in the interactions of Tunisian students at the faculty of Economics and Management in Sfax, Tunisia. The study focuses on students' (EMSs) classroom conversations and out-of-classroom peer interactions. The analysis of the social motivations of EMSs' CS behaviour shows that…

Upon hearing an ambiguous speech sound dubbed onto lipread speech, listeners adjust their phonetic categories in accordance with the lipread information (recalibration) that tells what the phoneme should be. Here we used sine wave speech (SWS) to show that this tuning effect occurs if the SWS sounds are perceived as speech, but not if the sounds…

The purpose of this dissertation is to empirically test the hypothesis that children's omission of functional elements reflects performance factors (McKee, 1994; McKee & Iwasaki, 2001), rather than lack of knowledge (Felix, 1987; Radford, 1990, 1995; Tomasello, 2000). The multi-level production system treats content and function morphemes…

Listeners segment words from the continuous speech stream in their native language by using rhythmic structure, phrasal structure, and phonotactics (e.g. Christophe et al, 2003: McQueen, 1998). One challenging aspect of second language acquisition is the extraction of words from fluent speech, possibly because learners apply a native language…

The core objective of this study was to examine whether acoustic variability of vowel production in American English, across speaking tasks, is systematic. Ten male speakers who spoke a relatively homogeneous Wisconsin dialect produced eight monophthong vowels (in hVd and CVC contexts) in four speaking tasks, including clear-speech, citation form,…

Proficiency in oral communication is necessary in school and in society. To do well in the different curriculum areas, pupils must speak with clarity and understanding. For example, in a discussion group in the social studies involving the topic "the pros and cons of raising taxes," pupils need to express knowledgeable ideas with appropriate voice…

Effective communication is essential for young children's academic and social competence. During the preschool years, children acquire the language and communication skills necessary to express their needs, thoughts, and feelings in social interactions, and they learn to respond appropriately to others. Through effective communication, they also…
