Purpose: We sought to determine whether speech perception and language skills measured early after cochlear implantation in children who are deaf, and early postimplant growth in speech perception and language skills, predict long-term speech perception, language, and neurocognitive outcomes. Method: Thirty-six long-term users of cochlear…

Purpose: The purpose of this study was to investigate the aging effect on the categorical perception of Mandarin Chinese tones with varied fundamental frequency (F0) contours and signal duration. Method: Both younger and older native Chinese listeners with normal hearing were recruited in 2 experiments--tone identification and tone discrimination…

Learning to recognize a stimulus category requires experience with its many natural variations. However, the mechanisms that allow a category's sensorineural representation to be updated after experiencing new exemplars are not well understood, particularly at the molecular level. Here we investigate how a natural vocal category induces expression…

Purpose: Listeners with hearing loss, as well as many listeners with clinically normal hearing, often experience great difficulty segregating talkers in a multiple-talker sound field and selectively attending to the desired "target" talker while ignoring the speech from unwanted "masker" talkers and other sources of sound. This…

Purpose: This review article provides a new perspective on the role of attention in auditory scene analysis. Method: A framework for understanding how attention interacts with stimulus-driven processes to facilitate task goals is presented. Previously reported data obtained through behavioral and electrophysiological measures in adults with normal…

Learning style has been considered as one of determining factors for learning processes. This study aimed at observing the correlation between students' learning style and performance of Nigerian students in biology. The sample of this study consisted of 100 students which were randomly selected from the secondary schools in Ifelodun LGA, Kwara…

Background: Literacy achievement of learners is a concern in many developing countries, particularly for English second language (EL2) learners with inadequate language development. It is important to investigate foundational phonological awareness (PA), as well as speech perception skills to guide the development of effective intervention for EL2…

Previous work suggests that adolescents are still refining acoustic-phonetic cue use in clear-speech perception. This study shows adolescents' immature perception of reduced speech, in which speech sounds are naturally deleted and merged within and across words. German adults and 16-year-olds listened to either German reduced or unreduced (few or…

This article reports on the influence of three modalities used in three versions of instructional software designed for different learning styles. Students having visual, auditory, and kinesthetic learning styles are grouped and experimentally investigated through three different versions of the software. The results indicated that cognitive load…

Purpose: This study tested the hypothesis that audiovisual training benefits children more than it does adults and that it improves Japanese-speaking children's English /r/-/l/ perception to a native-like level. Method: Ten sessions of audiovisual English /r/-/l/ identification training were conducted for Japanese-speaking adults and children.…

Purpose: Individuals vary in their ability to learn the sound categories of nonnative languages (nonnative phonetic learning) and to adapt to systematic differences, such as accent or talker differences, in the sounds of their native language (native phonetic learning). Difficulties with both native and nonnative learning are well attested in…

This study examined the effects of a 9-week auditory intervention on the auditory skills of five children with hearing loss who experienced prolonged auditory deprivation before receiving hearing aids. A single-case multiple baseline design across participants was used to examine the effect of the intervention on the children's auditory skills…

This paper focuses on Partial and Synchronized Caption (PSC) as a tool to train L2 listening and introduces new features to facilitate speech-related difficulties. PSC is an intelligent caption that extensively processes the audio and transcript to detect and present difficult words or phrases for L2 learners. With the new features, learners can…

This dissertation investigates how English-speaking second language (L2) learners of Mandarin perceive, process and learn Mandarin lexical tones. While most languages use modulations in pitch (intonation) to convey meanings at the phrasal and sentential levels, a number of languages, including Mandarin, also use suprasegmental features such as…

Purpose: General language abilities of children with cochlear implants have been thoroughly investigated, especially at young ages, but far less is known about how well they process language in real-world settings, especially in higher grades. This study addressed this gap in knowledge by examining recognition of sentences with complex syntactic…
