Parallel and generative binding in human visual cortex. Imagine watching a group of children running around in brightly coloured T-shirts. How does your brain keep track of which colour goes with which T-shirt goes with which child? This project will use magnetic resonance imaging to identify where in our brains information about colour, shape and motion gets put together.
Resolving multi-sensory conflict as we age: audio-visual integration and the role of normal and abnormal sensory decline. Australia has an ageing population. Even the healthiest older individuals undergo some deterioration of vision and hearing, however, these senses are almost invariably studied in isolation. The real world is multisensory. This project will enhance our knowledge of how ageing impacts on the interpretation of visual and auditory information regarding the timing and location of ....Resolving multi-sensory conflict as we age: audio-visual integration and the role of normal and abnormal sensory decline. Australia has an ageing population. Even the healthiest older individuals undergo some deterioration of vision and hearing, however, these senses are almost invariably studied in isolation. The real world is multisensory. This project will enhance our knowledge of how ageing impacts on the interpretation of visual and auditory information regarding the timing and location of objects; essential precursors to many real world tasks, for example: driving, interpreting speech, and hazard avoidance. This knowledge is essential for the optimisation of audio-visual environments for the elderly, and for the development of tools to improve performance in the presence of sensory decline due to age-related eye disease.Read moreRead less
The articulate brain. Language is essential to human interaction, yet we know comparatively little about the mental processes involved and how they are represented in the brain, how genetic and environmental factors contribute to the development of language, or how effective treatments of language disorders work. The significance of this program of research lies in its capacity to enhance our understanding of a range of mechanisms responsible for a fundamentally human ability, and provide inform ....The articulate brain. Language is essential to human interaction, yet we know comparatively little about the mental processes involved and how they are represented in the brain, how genetic and environmental factors contribute to the development of language, or how effective treatments of language disorders work. The significance of this program of research lies in its capacity to enhance our understanding of a range of mechanisms responsible for a fundamentally human ability, and provide information that will ultimately inform clinical practice. In particular, new knowledge about the brain mechanisms involved in language processing and recovery will inform clinicians about the optimal choice of treatment to maximise outcomes for the individual patient.

Seeing the forest and the trees: Cognitive and neural mechanisms underlying recognition of individual objects and sets. When confronted with a set of similar objects, such as a crowd of faces or a flow of oncoming cars, human observers can rapidly and seemingly automatically extract summary statistics of these sets of objects (e.g., mean expression or location). This research will provide insights into how the human visual system executes this massive feat of computation. This represents a vital ....Seeing the forest and the trees: Cognitive and neural mechanisms underlying recognition of individual objects and sets. When confronted with a set of similar objects, such as a crowd of faces or a flow of oncoming cars, human observers can rapidly and seemingly automatically extract summary statistics of these sets of objects (e.g., mean expression or location). This research will provide insights into how the human visual system executes this massive feat of computation. This represents a vital step in understanding vision in general and in eventually applying our knowledge to the development of artificial vision systems and to rehabilitation of visual disorders. The research will also investigate the effects of attentional load on perception of summary statistics of the environment, which is critical for tasks such as driving in busy traffic.Read moreRead less
