The effect of cochlear implants on cognitive decline in ageing Australians. This project aims to investigate the impact of cochlear implants on cognitive function in elderly people with deafness. Deafness has been found to be independently associated with a 30–40 per cent accelerated rate of cognitive decline in elderly adults. There is currently no effective treatment for cognitive decline. The intended outcomes of this observational study will help us to understand the biological process of co ....The effect of cochlear implants on cognitive decline in ageing Australians. This project aims to investigate the impact of cochlear implants on cognitive function in elderly people with deafness. Deafness has been found to be independently associated with a 30–40 per cent accelerated rate of cognitive decline in elderly adults. There is currently no effective treatment for cognitive decline. The intended outcomes of this observational study will help us to understand the biological process of cognitive decline, whether hearing loss is causal, and whether the process can be altered. These findings should be applicable to all individuals with hearing loss. If cochlear implants delay cognitive decline, this would significantly affect policy, quality of life for the elderly, and the cost to society.Read moreRead less
Optimal Training Methods for Lexical Tone Perception by Children with Cochlear Implants: Application of Experimental Psychology Techniques. Cochlear implants (CIs) stimulate the auditory nerve via electrodes in the cochlear to provide auditory information to people who would otherwise be functionally deaf. Cochlear site stimulation is at a constant rate so, despite the genius of the CI, it cannot convey pitch information effectively. Such information is essential for perceiving and speaking ton ....Optimal Training Methods for Lexical Tone Perception by Children with Cochlear Implants: Application of Experimental Psychology Techniques. Cochlear implants (CIs) stimulate the auditory nerve via electrodes in the cochlear to provide auditory information to people who would otherwise be functionally deaf. Cochlear site stimulation is at a constant rate so, despite the genius of the CI, it cannot convey pitch information effectively. Such information is essential for perceiving and speaking tone languages, in which word meaning depends on consonants, vowels, and tones (conveyed mainly by pitch). A training method to improve tone perception will be developed with non-tone language non-CI through to tone language CI children drawing on experimental psychology methods, auditory and visual (lip & face) speech information, exaggerated tone cues, and metalinguistic instruction.Read moreRead less
Image processing techniques for artificial human vision systems. Blindness affects millions of people worldwide and over 100,000 Australians. Our project supports quality of life improvements for them by developing image processing techniques necessary for artificial human vision systems: "bionic eyes". Our approach will extract the most visually informative content in a scene,allowing low resolution images to be generated which optimise usage of the limited number of eletrodes available in prot ....Image processing techniques for artificial human vision systems. Blindness affects millions of people worldwide and over 100,000 Australians. Our project supports quality of life improvements for them by developing image processing techniques necessary for artificial human vision systems: "bionic eyes". Our approach will extract the most visually informative content in a scene,allowing low resolution images to be generated which optimise usage of the limited number of eletrodes available in prototype bionic eye implants. Psychophysical tests presenting such modified images to normally sighted participants will verify the effectiveness of this approach. The techniques developed will provide a real-time image processing toolkit for visual protheses, with significant commercial and social benefits including enhancement of Australilia's neuroprostheses industry profile.Read moreRead less
Factors impacting on workplace retention in speech pathology. Retention of speech pathologists within their profession and within the public service is presenting a major problem for the professional association, the public service and service users. In repsonse to this situation our study aims to measure the psychological well being of speech pathologists nationally and to identify workplace dimensions that are hindering or enhancing retention. The results of this study will be of significance ....Factors impacting on workplace retention in speech pathology. Retention of speech pathologists within their profession and within the public service is presenting a major problem for the professional association, the public service and service users. In repsonse to this situation our study aims to measure the psychological well being of speech pathologists nationally and to identify workplace dimensions that are hindering or enhancing retention. The results of this study will be of significance to all stakeholders, in particularly individuals with communication disorders. The successful retention of experienced speech pathologists within the profession and the public sector will help ensure expert services are available to Australia's ageing population.Read moreRead less
Beyond Speech: Towards better communication for children with hearing loss. Despite the benefits of early newborn hearing screening and early intervention programs for children with hearing loss, most still experience academic and social challenges at school. This is partly due to ongoing listening effort, leading to communicative breakdown. This project aims to identify the locus of the communicative challenges these children face during daily discourse interactions. The outcomes will identify ....Beyond Speech: Towards better communication for children with hearing loss. Despite the benefits of early newborn hearing screening and early intervention programs for children with hearing loss, most still experience academic and social challenges at school. This is partly due to ongoing listening effort, leading to communicative breakdown. This project aims to identify the locus of the communicative challenges these children face during daily discourse interactions. The outcomes will identify which levels of language are most compromised and will inform future interventions to reduce children’s listening effort. This will be undertaken by bringing together researchers in basic science with hearing service providers, parents and industry, providing an innovative model for solving multidisciplinary challenges.Read moreRead less
Physiologically accurate audio processing in cochlear implants. This project proposes to use a physiologically motivated computational model of the cochlea, which along with newly developed cochlear-implant electrode technology will produce the next quantum improvement in speech intelligibility and quality of hearing for implant recipients.

Captions for the Deaf and Hearing Impaired: Availability versus Accessibility. The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings. These innovations must be matched by equally innovative ways of increasing the accessib ....Captions for the Deaf and Hearing Impaired: Availability versus Accessibility. The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings. These innovations must be matched by equally innovative ways of increasing the accessibility of captions, which is currently limited by English literacy, caption speed, and caption reduction techniques. Here, systematic manipulation of these factors in experiments on television captioning with adults and educational captioning with children will determine how resources might best be directed to improving caption accessibility.Read moreRead less
Tonal language development in Mandarin and Cantonese-speaking children with cochlear implants. Cochlear implantation in children is expanding in countries where tonal languages are spoken, despite limited evidence of the effectiveness of implant use in these settings. This project will examine the impact of implant use on children's perception of tone, their production of speech and assesses how this affects functional communication.

Australia has workforce shortages and an ageing population. Physiotherapists are key players in promoting and maintaining good health through their leadership in physical activity and rehabilitation to retain Australians in the workforce and to ensure quality of life for our ageing population. There is a national shortage of physiotherapists. Increasing numbers of physiotherapists are being trained, requiring new models of clinical training as there is no capacity in conventional training to cope with student numbers. This research will develop and evaluate new models of training incorporating standardised patients (actors) and simulators (mannequins) which increase education capacity. Models are transferable to other health professions.Read moreRead less
