Attention vs Perception: When is selection optimal, when relational? This project aims to investigate an important, newly discovered dissociation between early visual selection and perceptual decision-making. Contrary to current theories, attentional and perceptual processes are tuned to different stimulus attributes described in the relational vs. optimal account, which implies that current theories of attention do not describe early attention but later, decisional processes. This project will ....Attention vs Perception: When is selection optimal, when relational? This project aims to investigate an important, newly discovered dissociation between early visual selection and perceptual decision-making. Contrary to current theories, attentional and perceptual processes are tuned to different stimulus attributes described in the relational vs. optimal account, which implies that current theories of attention do not describe early attention but later, decisional processes. This project will provide an accurate description of these processes, which promises important theoretical breakthroughs. Work on this project will also significantly advance methods to detect and describe early attentional processes, by identifying error-prone methods of Psychophysics and Neuroscience studies, and proposing remedies.Read moreRead less
Cortical topology underlying the representation and analysis of visual scenes. When we look around us we seem to perceive our visual surroundings fully, accurately and instantaneously. Despite this strong impression, recent research has revealed that none of this is true. Using virtual environments, brain imaging and neural network simulations, this project aims to discover more about what we do see, which part of our brain stores what we see, and how this storage takes place. The work has the p ....Cortical topology underlying the representation and analysis of visual scenes. When we look around us we seem to perceive our visual surroundings fully, accurately and instantaneously. Despite this strong impression, recent research has revealed that none of this is true. Using virtual environments, brain imaging and neural network simulations, this project aims to discover more about what we do see, which part of our brain stores what we see, and how this storage takes place. The work has the potential to influence the design of danger signs, teleoperated and virtual displays and autonomous machines. It should also help motivate new treatments and rehabilitation regimes for stroke victims.Read moreRead less
Can the Relational Account predict search in multiple-element displays? . This project provides evidence of a novel mechanism that guides visual attention. Our results confirm the existence of a mechanism that can rapidly and automatically assess the dominant feature(s) in a visual scene and radically change how attention is tuned to a target object. Moreover, this attention-guiding target template can change systematically as observers search through different items in visual search, possibly d ....Can the Relational Account predict search in multiple-element displays? . This project provides evidence of a novel mechanism that guides visual attention. Our results confirm the existence of a mechanism that can rapidly and automatically assess the dominant feature(s) in a visual scene and radically change how attention is tuned to a target object. Moreover, this attention-guiding target template can change systematically as observers search through different items in visual search, possibly due to a re-shaping and narrowing of the target template. These are both ground-breaking discoveries that have not been described before. Work on this project promises to lead to important theoretical breakthroughs, resolve current discrepancies in the literature and advance methods of Cognitive Psychology and Neuroscience.Read moreRead less

Summary
The Creation of an Eye Movement Recording Facility in Queensland. There are countless uses for technology that records visual behaviour; these include reading and cognitive psychology research, ergonomic design, web site usability testing, and evaluation of visual information (for example advertising or in ?virtual? environments). As such, recording eye movements has applications in pure and applied research, and in teaching demonstrations for students.

There are countless uses for technology that records visual behaviour; these include reading and cognitive psychology research, ergonomic design, web site usability testing, and evaluation of visual information (for example advertising or in ?virtual? environments). As such, recording eye movements has applications in pure and applied research, and in teaching demonstrations for students.
This application proposes to purchase eye movement recording equipment to form a dedicated and truly collaborative facility to measure visual behaviour. The facility would be unique in Australia and would be invaluable to both further understand visual/cognitive processes and how individuals interact with their environments.Read moreRead less
Cortical regulation of attentional capture. The proposed experiments examine how brain mechanisms interact to determine whether a stimulus will capture our attention, distracting us from the task at hand. The experiments test competing theories of attentional control and have implications for clinical populations (for example, stroke) that have difficulty avoiding distraction.
Multimodal testing for a fast subcortical route for salient visual stimuli. This project aims to uncover links between underlying brain circuitry, uncertainty and consciousness, and perceptions of fear. The project will use a multi-modal combination of brain imaging and neural recording techniques to generate new knowledge about the brain’s processing of biologically relevant information. The expected outcomes will enhance our knowledge of how the brain rapidly and non-consciously prepares the ....Multimodal testing for a fast subcortical route for salient visual stimuli. This project aims to uncover links between underlying brain circuitry, uncertainty and consciousness, and perceptions of fear. The project will use a multi-modal combination of brain imaging and neural recording techniques to generate new knowledge about the brain’s processing of biologically relevant information. The expected outcomes will enhance our knowledge of how the brain rapidly and non-consciously prepares the body for potential escape behaviours and of the brain pathways engaged in fear perception. The outcomes have the potential to inform strategies for overcoming anxiety and its effects on daily life, social interactions and workplace productivity.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
Intervalence Transfer in Dinuclear and Oligonuclear Polymetallic Assemblies. Mixed-valence compounds (such as the pigment Prussian Blue) have been known for over two centuries, and possess important conductivity, magnetic and spectral properties. Electron transfer between the elements of different valency (intervalence charge transfer, IVCT) gives rise to absorbances in the red or near-infrared region of the spectrum which provide fundamental information on the electron migration. By design of ....Intervalence Transfer in Dinuclear and Oligonuclear Polymetallic Assemblies. Mixed-valence compounds (such as the pigment Prussian Blue) have been known for over two centuries, and possess important conductivity, magnetic and spectral properties. Electron transfer between the elements of different valency (intervalence charge transfer, IVCT) gives rise to absorbances in the red or near-infrared region of the spectrum which provide fundamental information on the electron migration. By design of target di- and higher nuclearity polymetallic species, the project will study IVCT phenomena to understand electron movement, allowing rational development of applicable materials such as catalysts, light-activated devices and non-linear optical materials.Read moreRead less
THE UNWRITTEN HISTORY OF AUSTRALIAN MODERNISM. Most histories treat modernism in Australia as a phenomenon of ?fine art,? or simply painting. This project will instead reveal modernism's highly public impact across a range of media (design, photography, advertising, architecture and art). This new history will better explain how modernist visual idioms became ubiquitous in everyday contemporary design and our built environment after their initial, often hostile reception. The project will provid ....THE UNWRITTEN HISTORY OF AUSTRALIAN MODERNISM. Most histories treat modernism in Australia as a phenomenon of ?fine art,? or simply painting. This project will instead reveal modernism's highly public impact across a range of media (design, photography, advertising, architecture and art). This new history will better explain how modernist visual idioms became ubiquitous in everyday contemporary design and our built environment after their initial, often hostile reception. The project will provide an integrated research analysis of the extensive, but disparate, archives on Australian modernism. It will communicate its research findings through a new scholarly study, a major large-scale travelling public exhibition, a CD, and a website.Read moreRead less
