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
New, Efficient Tests That Map Both Central and Peripheral Vision. This project seeks to develop a new, combined approach for quantifying both central and peripheral vision with a single test. Current methods for testing far peripheral vision are not efficient and not fully automated. Yet peripheral vision is important for tasks involving navigation and hazard avoidance such as driving. The project intends to invent and test new approaches to sampling and measuring the spatial extent of vision. T ....New, Efficient Tests That Map Both Central and Peripheral Vision. This project seeks to develop a new, combined approach for quantifying both central and peripheral vision with a single test. Current methods for testing far peripheral vision are not efficient and not fully automated. Yet peripheral vision is important for tasks involving navigation and hazard avoidance such as driving. The project intends to invent and test new approaches to sampling and measuring the spatial extent of vision. The anticipated algorithms will be more accurate and efficient than current tests, will be suitable for older adults, and will enable ready assessment of vision for occupational tasks.Read moreRead less
Vision Impairment and Fitness to Drive. Vision is fundamental to driving. Intuitively vision impairments will significantly affect fitness to drive. However the relationship between vision and crash risk is not well understood and current tests are unreliable. This study will describe the way in which specific vision conditions affect driving performance. The study will examine the effects of visual field loss on drivers' ability to monitor information, allocate attention and minimise the effect ....Vision Impairment and Fitness to Drive. Vision is fundamental to driving. Intuitively vision impairments will significantly affect fitness to drive. However the relationship between vision and crash risk is not well understood and current tests are unreliable. This study will describe the way in which specific vision conditions affect driving performance. The study will examine the effects of visual field loss on drivers' ability to monitor information, allocate attention and minimise the effect of distractions. Outcomes of the study will enable the development of evidence-based guidelines for assessment of vision for driving and effective countermeasures to enhance mobility and reduce crash risk.Read moreRead less
Biomarkers and objective assessment of cognitive and brain effects of fish oil dietary supplementation. There are potential widespread community benefits from knowing whether consuming fish oils will improve cognitive function. This is mainfest in children and even more so in those suffering attention deficits at a time when inattention and hyperacitvity is likely to permanently lower their overall career prospects.
Exploiting high resolution images of the retina to customise vision tests. This project will make vision tests more accurate and faster by using a person's individual eye anatomy to customise the test. The basic understandings discovered in this project are expected to be applied in clinical and research settings thus saving sight, dollars and time.
Smart algorithms for visual field assessment. Australian demographic studies show that visual impairment contributes significantly to elderly disability. Visual field loss due to glaucoma, the second leading cause of blindness in developed nations, may be slowed if detected early, but recent studies estimate 50% of Australians with glaucoma are undiagnosed. The fast and effective approaches to measuring visual fields discovered in this project will allow more accurate diagnosis and monitoring of ....Smart algorithms for visual field assessment. Australian demographic studies show that visual impairment contributes significantly to elderly disability.

The fast and effective approaches to measuring visual fields discovered in this project will allow more accurate diagnosis and monitoring of vision loss; crucial for the ARC's priority goals of "ageing well, ageing productively" and "preventative healthcare". Developing smart algorithms in conjunction with Heidelberg Engineering creates an opportunity for the international promotion of Australia's biomedical software capabilities.Read moreRead less

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
