Purpose: This study examined the ability of listeners using cochlear implants (CIs) and listeners with normal hearing (NH) to identify silent gaps of different duration and the relation of this ability to speech understanding in CI users. Method: Sixteen NH adults and 11 postlingually deafened adults with CIs identified synthetic vowel-like…

This research developed a multimodal picture-word task for assessing the influence of visual speech on phonological processing by 100 children between 4 and 14 years of age. We assessed how manipulation of seemingly to-be-ignored auditory (A) and audiovisual (AV) phonological distractors affected picture naming without participants consciously…

This dissertation presents an empirical analysis of Korean hedges in contemporary spoken discourse. The data analyzed was drawn from my corpus based on approximately 17 hours of unplanned, naturally occurring conversations. This study classified lexical and syntactic hedges in my corpus and investigated the frequency of individual hedge items. It…

The central purpose of this three-paper dissertation was to explore the ability of school-age children with and without language-learning disabilities (LLD) to apply sound/word level structure knowledge when performing speaking, spelling, and reading tasks. Data came from a larger investigation that used stratified sampling to create two ability…

Previous research demonstrates enhanced speech perception abilities for typically hearing and hearing-impaired listeners when speakers use clear versus plain speech, particularly in the presence of background noise. To date, very few studies have investigated the effects of noise on word learning and no studies have examined the effects of clear…

Research on learning to teach mathematics reveals that mathematics teaching is a complex process (Lerman, 2000) and classroom teaching and learning is a "multifaceted, extraordinarily complex phenomenon" (O'Connor, 1998, p. 43). Moreover, research reveals that the mathematics reform agenda has had an impact on what happens in the mathematics…

Background: Children with word-finding difficulties manifest a high frequency of word-finding characteristics in narrative, yet word-finding interventions have concentrated on single-word treatments and outcome measures. Aims: This study measured the effectiveness of a narrative-based intervention in improving single-word picture-naming and…

This study compared two phonological assessment tools for use with young Spanish-speaking children in the American Southwest, FON and STAR. Each was administered to 27 1-, 2- and 3-year-old monolingual Spanish-speaking children in the greater Phoenix area. Analyses compared the children's rate of response, complexity of the children's productions,…

To meet the needs of a diverse student population while addressing the knowledge and skills outcomes of the curriculum, faculty should develop a repertoire of instructional models. Research-based instructional models from the fields of education and health care have been developed to support various learner outcomes. Emphasis on evidence-based…

To improve more effectively the learners' proficiency to control contrast of the stressed to the unstressed in English teaching, it is necessary to analyze how the acoustical characteristics of learners' speech are related to the perceptual evaluation by teachers. This paper analyzes A) learner characteristics of durations measured in speech units…

Purpose: The well-known decline in the use of African American English (AAE) features by groups of school-aged AAE-speaking children was reexamined for patterns of overt-, zero-, and mixed-marking for individual features and individual speakers. Methods: Seven hundred twenty-nine typically developing children between the ages of 4 and 12--511…

This article explores the process of embedding information literacy into a basic oral communication course. Discussion includes student performance as an impetus for change, collaborative course design between the oral communication teaching team and instructional librarians, and assessment initiatives.

This research examined how students in foundation English classes perceive their Thai and native-speaking teachers. The researchers surveyed students at five universities and compared a group of 600 students studying with native-speaking teachers with another group of 600 students studying with Thai teachers in order to investigate three areas:…

The relationship between maternal ADHD symptoms and maternal language was examined in a community sample of 50 mothers of infants age 3-12 months. It was hypothesized that higher maternal symptoms of ADHD would be related to lower quality of maternal language use. Recordings of mothers' speech were coded for complexity and elaboration of speech…
