This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: (Uncorrected OCR) Abstract of dissertation entitled Tone Perception Performance of Cantonese-speaking Prelingually Deaf Children with Cochlear Implants submitted by Angela On-Chi Wong for the degree of Master of Sciences in Audiology at the University of Hong Kong in May 2000 The present study was a preliminary investigation on the tone perception performance of pre lingually hearing-impaired children with cochlear implant. Seventeen native Cantonese-speaking participants were invited in this research. They have been using the Nucleus multichannel cochlear implant with coding strategy of either SPEAK or ACE. Errors from the tone discrimination and the tone identification tests were examined and a tone confusion matrix was plotted. Results revealed that the correct scores for both discrimination and identification tests were slightly above chance levels, indicating that prelingually hearing-impaired children using cochlear implants were able to benefit from SPEAK or ACE strategies for Cantonese tone perception, though the benefit was small. Tonal error and confusion patterns were discussed and some contributing possibilities were suggested. Relationships between tone perception VII performance and other variables such as age at implantation, duration of implantation, frequency of training and overall auditory performance were also examined. The paper also discussed other possibilities that may contribute to tone confusion. VIII.

This book was released on 2019-11-20 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: In psycholinguistic research there has traditionally been a strong emphasis on understanding how particular language types of are processed and learned . In particular, Romance and Germanic languages (e.g. English, French, German) have, until recently, received more attention than other types, such as Chinese languages. This has led to selective emphasis on the phonological building blocks of European languages, consonants and vowels, to the exclusion of lexical tones which, like consonants and vowels, determine lexical meaning, but unlike consonants and vowels are based on pitch variations. Lexical tone is pervasive; it is used in at least half of the world’ languages (Maddieson, 2013), e.g., most Asian and some African, Central American, and European languages. This Research Topic brings together a collection of recent empirical research on the processing and representation of lexical tones across the lifespan with an emphasis on advancing knowledge on how tone systems are acquired. The articles focus on various aspects of tone: early perception of tones, influences of tone on word learning, the acquisition of new tone systems, and production of tones. One set of articles report on tone perception at the earliest stage of development, in infants learning either tone or non-tone languages. Tsao and Chen et al. demonstrate that infants’ sensitivity to Mandarin lexical tones, as well as pitch, improves over the first year of life in native and non-native learners in contrast to traditional accounts of perceptual narrowing for consonants and vowels. Götz et al. report a different pattern of perception for Cantonese tones and further demonstrate influences of methodological approaches on infants’ tone sensitivity. Fan et al. demonstrate that sensitivity to less well-studied properties of tone languages, such as neutral tone, may develop after the first year of life. Cheng and Lee ask a similar question in an electrophysiological study and report effects of stimulus salience on infants’ neural response to native tones. In a complementary set of studies focused on tone sensitivity in word learning, Burnham et al. demonstrate that infants bind tones to newly-learned words if they are learning a tone language, either monolingually or bilingually; although it was also found that object-word binding was influenced by the properties of individual tones. Liu and Kager chart a developmental trajectory over the second year of life in which infants narrow in their interpretation of non-native tones. Choi et al. investigate how learning a tone language can influence uptake of other suprasegmental properties of language, such as stress, and demonstrate that native tone sensitivity in children can facilitate stress sensitivity when learning a stress-based language. Finally, two studies focus on sensitivity to pitch in a sub-class tone languages: pitch accent languages. In a study on Japanese children’s abilities to recognise words they know, Ota et al. demonstrate a limited sensitivity to native pitch contrasts in toddlers. In contrast, Ramachers et al. demonstrate comparatively strong sensitivity to pitch in native and non-native speakers of a different pitch accent system (Limburghian) when learning new words. Several studies focus on learning new tone systems. In a training study with school-aged children, Kasisopa et al. demonstrate that tone language experience increases children’s abilities to learn new tone contrasts. Poltrock et al. demonstrate similar advantages of tone experience in learning new tone systems in adults. And in an elecrophysiological study, Liu et al. demonstrate order effects in adults’ neural responses to new tones, discussing implications for learning tone languages as an adult. Finally, Hannah et al. demonstrate that extralinguistic cues, such as facial expression, can support adults’ learning of new tone systems. In three studies investigating tone production, Rattansone et al. report the results of a study demonstrating kindergartners’ asynchronous mastery of tones – delayed acquisition of tone sandhi forms relative to base forms. In a study interrogating a corpus of adult tone production, Han et al. demonstrate that mothers produce tones in a distinct manner when speaking to infants; tone differences are emphasised more when speaking to infants than to adults. Combining perception and production of tones, Wong et al. report asynchronous development of tone perception and tone production in children. The Research Topic also includes a series of Opinion pieces and Commentaries addressing the broader relevance of tone and pitch to the study of language acquisition. Curtin and Werker discuss ways in which tone can be integrated into their model of infant language development (PRIMIR). Best discusses the phonological status of lexical tones and considers how recent empirical research on tone perception bears on this question. Kager focuses on how language learners distinguish lexical tones from other sources of pitch variation (e.g., affective and pragmatic) that also inform language comprehension. Finally, Antoniou and Chin unite evidence of tone sensitivity from children and adults and discuss how these areas of research can be mutually informative. Psycholinguistic studies of lexical tone acquisition have burgeoned over the past 13 years. This collection of empirical studies and opinion pieces provides a state-of-the-art panoply of the psycholinguistic study of lexical tones, and demonstrate its coming of age. The articles in this Research Topic will help address the hitherto Eurocentric non-tone language research emphasis, and will contribute to an expanding narrative of speech perception, speech production, and language acquisition that includes all of the world’s languages. Importantly, these studies underline the scientific promise of drawing from tone languages in psycholinguistic research; the research questions raised by lexical tone are unique and distinct from those typically applied to more widely studied languages and populations. The comprehensive study of language acquisition can only benefit from this expanded focus.

Abstract: Abstract of thesis entitled "Postoperative Strategies to Improve the Benefit of Cochlear Implantation in a Cantonese-Speaking Population" Submitted by JIN Hao for the degree of Master of Philosophy at The University of Hong Kong in December 2003 The present study contains two parts. In the first part, the changes in psychophysical levels of threshold (THR) and maximum comfortable level (MCL) over time were retrospectively analyzed to evaluate the feasibility of ''early switch-on'' of speech processor after implantation. The second part aimed at evaluating the effects of two independent parameters, stimulation rate and electrode insertion depth, on Cantonese tone perception in quiet and against a background noise in Cantonese-speaking cochlear implant (CI) users. The first part included 24 adults and 33 children implanted with the MED-EL Tempo+ CI system between August 1999 and December 2001. They had an initial mapping of speech processor on the next day after implantation. Subsequent mappings were scheduled on 7, 14, 21, 28, 60, 90, 120, and 180 days after implantation. In adults, there was a rapid increase in THR over the first 7 days, after which followed by a decreasing period up to 21 days after implantation. After that, THR remained stable. In children, THR increased gradually with time and the trend was relatively stable without fluctuations. MCL in adults increased significantly within the first 7 days and then showed a slow steady rise in the subsequent days. In children, MCL increased in a slower rate within the first 7 days compared to adults but increased continuously up to 90 days after implantation. Except for the fluctuation of THR within the initial 3 weeks in adults, no prolonged periods with fluctuations in psychophysical THR and MCL were observed and the levels changed steadily. The second part consists of two independent experiments conducted in 18 postlingually deafened adults implanted with the MED-EL Tempo+ CI system. In Experiment I, stimulation rates of 1515, 800, and 400 pulses per second per channel (pps/ch) were selected to represent high, moderate, and low stimulation rate conditions, respectively. For tone discrimination, significant improvements in correct percent were observed when stimulation rate was increased from low to high at signal-to-noise ratios (SNRs) of 0, +5, and +10, and from low to moderate at SNR of +5. For tone identification, significantly better scores were achieved at high stimulation rate compared to low at SNRs of -5, and 0. In Experiment II, electrode insertion depths of 31.3, 25.5, and 18.3 mm were simulated to represent deep, medium, and shallow electrode insertion conditions, respectively. The results of both tone discrimination and tone identification did not show any significant changes as electrode insertion depth varied. However, better sound quality was reported with the electrode insertion depths to 25 mm. The overall results from this study indicate that both adults and children could adapt to early electrical stimulation. ''Early switch-on'' after implantation is feasible and may be able to facilitate earlier rehabilitation. High stimulation rate of 1515 pps/ch is recommended, which significantly benefits Cantonese tone perception against a background noise. Deep electrode insertion into the cochlea does no significant effect on Cantonese tone perception. However, the sound quality can be im

Available in PDF, EPUB and Kindle. Book excerpt: Cochlear implants are currently the standard treatment for profound sensorineural hearing loss. In the last decade, advances in auditory science and technology have not only greatly expanded the utility of electric stimulation to other parts of the auditory nervous system in addition to the cochlea, but have also demonstrated drastic changes in the brain in responses to electric stimulation, including changes in language development and music perception. Volume 20 of SHAR focused on basic science and technology underlying the cochlear implant. However, due to the newness of the ideas and technology, the volume did not cover any emerging applications such as bilateral cochlear implants, combined acoustic-electric stimulation, and other types of auditory prostheses, nor did it review brain plasticity in responses to electric stimulation and its perceptual and language consequences. This proposed volume takes off from Volume 20, and expands the examination of implants into new and highly exciting areas. This edited book starts with an overview and introduction by Dr. Fan-Gang Zeng. Chapters 2-9 cover technological development and the advances in treating the full spectrum of ear disorders in the last ten years. Chapters 10-15 discuss brain responses to electric stimulation and their perceptual impact. This volume is particularly exciting because there have been quantum leap from the traditional technology discussed in Volume 20. Thus, this volume is timely and will be of real importance to the SHAR audience.
