Brain structure and function of neonates at risk for stuttering. The aim of the project is to determine whether the brain abnormalities that have been found in people who stutter are present at birth. The hypothesis is that the brains of neonates who subsequently start to stutter will differ significantly from those who do not. This is the first project to investigate the brains of infants before they start to stutter.
Relationship of retinal directionality to human retinal anatomy variations. This project aims to improve measurement of retinal directionality, which is the reduction in brightness when a light beam’s entry into the human eye is shifted from the centre to the edge of the pupil. This influences retinal image quality and can be used to measure changes in shape of the peripheral eye. This project will apply advanced technologies in holography, and heads-up displays to explore how retinal directiona ....Relationship of retinal directionality to human retinal anatomy variations. This project aims to improve measurement of retinal directionality, which is the reduction in brightness when a light beam’s entry into the human eye is shifted from the centre to the edge of the pupil. This influences retinal image quality and can be used to measure changes in shape of the peripheral eye. This project will apply advanced technologies in holography, and heads-up displays to explore how retinal directionality changes during accommodation (focusing). The expected outcome is improved understanding of retinal stretching changes during focusing. The benefit is that the project will lead to advancements in retinal imaging.Read moreRead less
Removing the blinkers: a wider study of the human eye. Peripheral aberrations, wide-field retinal imaging and optical parameters. This project will study peripheral (side vision) optics of the human eye and its role in the limits of visual performance. This will improve ocular measurements and contribute towards improved diagnosis and treatment of ocular diseases and short-sightedness.
Advanced methods for intraocular imaging. The ability to image the retina of the human eye at high resolution is fundamental to improving understanding of ocular physiology, ocular optics and disease diagnosis. This project applies the relatively new application of active optics to vision science. This project will investigate the advantages of using new beam shaping techniques for characterising the optics of the eye, improving retinal imagery and improving fixation stability. This project will ....Advanced methods for intraocular imaging.

This project applies the relatively new application of active optics to vision science. This project will investigate the advantages of using new beam shaping techniques for characterising the optics of the eye, improving retinal imagery and improving fixation stability. This project will achieve three-dimensional holography of human eyes and develop holography plates for correcting the aberrations of eyes. Expected outcomes are not-before experienced resolution images of the retina and better understanding of the optical characteristics of the refractive surfaces and media in the eye.Read moreRead less
Neural mechanisms for human form perception. This project aims to determine if there is a single cortical mechanism underlying the human ability to discriminate and recognise objects. It has been speculated that different classes of objects, or forms require different processes. Demonstrating a single process would be a significant advance towards understanding the neural mechanisms giving rise to our ability to segment visual fields into meaningful objects and background. This research provides ....Neural mechanisms for human form perception. This project aims to determine if there is a single cortical mechanism underlying the human ability to discriminate and recognise objects. It has been speculated that different classes of objects, or forms require different processes. Demonstrating a single process would be a significant advance towards understanding the neural mechanisms giving rise to our ability to segment visual fields into meaningful objects and background. This research provides a means for testing models of the neural interactions thought to be generating human form perception and will help us discover how the visual cortex converts raw sensory input into object and form perception.Read moreRead less
A process model of visual working memory. This project aims to develop a process model of encoding of items into memory. Working memory is central to almost all cognitive functions, but little is known about short-term memory for visual information. Progress in this area is slow because of a focus on models that do not specify the processes underlying memory, and no model explains the processes that would limit the number of items the memory can hold to four. A process model is expected to addre ....A process model of visual working memory. This project aims to develop a process model of encoding of items into memory.

The flipside of noise: Does it benefit listening and learning? People with low attention capacity can experience improvements in cognitive function (eg memory) in the presence of external white noise. This project aims to determine the brain mechanisms for this improvement and how it affects oral language comprehension and verbal learning. In doing so, the research would change the prevailing view that noise is always detrimental to mental processes, and provide a theoretical framework for predi ....The flipside of noise: Does it benefit listening and learning? People with low attention capacity can experience improvements in cognitive function (eg memory) in the presence of external white noise. This project aims to determine the brain mechanisms for this improvement and how it affects oral language comprehension and verbal learning. In doing so, the research would change the prevailing view that noise is always detrimental to mental processes, and provide a theoretical framework for predicting how an individual’s cognitive capacity is affected by the presence of noise. It may support the development of methods to improve educational participation and outcomes for children, particularly those with lower attention, and for older adults.Read moreRead less

The question ?What does it mean to be Australian?? raises issues of deep significance about our values, goals, loyalties, behaviours, and international image. Identity conceptions are fundamental to diverse national interest issues (e.g., social cohesion, multiculturalism, defence, promoting industry, social action/reform, immigration) and imagining our future. This study will characterise: national identity; personal, ethnic, generational, regional and gender commonalities and variations; preferred futures; and moderating influences on identifying as Australian. Outcomes include new knowledge about contemporary national identity, multi-identity constructions, and processes underpinning identity formation; and advances in identity theory/research that will inform social, economic, and educational policy and practice.Read moreRead less
