Hazard Perception and Cognitive Ageing in Older Drivers: Investigation and Development. Older road users have high fatal crash rates that cost the Australian economy $500 million each year. However, driving cessation is associated with depression and reduced social participation among older adults. The present study will benefit older road users and the wider community by identifying which traffic hazards pose the greatest difficulty for older drivers and providing information that may lead to a ....Hazard Perception and Cognitive Ageing in Older Drivers: Investigation and Development. Older road users have high fatal crash rates that cost the Australian economy $500 million each year. However, driving cessation is associated with depression and reduced social participation among older adults. The present study will benefit older road users and the wider community by identifying which traffic hazards pose the greatest difficulty for older drivers and providing information that may lead to adaptation of roads, and vehicles to reduce crash risk among older Australians. This will reduce injury and healthcare costs and allow older Australians to maintain higher levels of social participation.Read moreRead less
Radicalisation, Counter-Radicalisation, and De-Radicalisation: Developing a New Understanding of Terrorism in the Australian Context. Concentrating on the unique drivers of extremism within Victoria (and Australia), the study will enhance counter terrorism stakeholders' understanding of domestic radicalization. This will assist in designing policies appropriate for Australian circumstances that can: 1. pre-empt, prevent and detect radicalisation without jeopardising social cohesion and 2. reduce ....Radicalisation, Counter-Radicalisation, and De-Radicalisation: Developing a New Understanding of Terrorism in the Australian Context. Concentrating on the unique drivers of extremism within Victoria (and Australia), the study will enhance counter terrorism stakeholders' understanding of domestic radicalization. This will assist in designing policies appropriate for Australian circumstances that can: 1. pre-empt, prevent and detect radicalisation without jeopardising social cohesion and 2. reduce Australia's reliance on overseas counter-radicalisation and de-radicalisation models, where practitioners confront different community dynamics. Working towards understanding what causes radicalization in Australia, the project offers to enhance national security and by addressing local circumstances carries the prospect of creating more cost-efficient counter terrorism practices.Read moreRead less

In the international setting, visual psychophysics is playing a major role in this development. The present project will help maintain Australia's international competitiveness in this rapidly growing field. Also, given how important being able to accurately perceive motion is to our ability to safely interact with the world, there are a number of potential applied benefits of the proposed research. These benefits range from areas like road safety to clinical neuropsychology.Read moreRead less
Perceiving and tracking moving objects. Processing and tracking moving objects poses challenges for human perception. To succeed, visual processing must accumulate analyses of the object from its different positions. Perceptual experiments will reveal human limits and yield insights into the underlying mechanisms, providing a basis for understanding object tracking in tasks like driving.
The causes and consequences of attentional rescaling. This project aims to investigate the mechanisms that underlie people’s capacity to rescale the focus of their visual attention. Such rescalings are important because they are linked with people’s capacity to perform specific tasks. Using an innovative approach within cognitive psychology that integrates individual differences, experimental, and training frameworks, this project expects to generate new theoretical knowledge about attentional ....The causes and consequences of attentional rescaling. This project aims to investigate the mechanisms that underlie people’s capacity to rescale the focus of their visual attention. Such rescalings are important because they are linked with people’s capacity to perform specific tasks. Using an innovative approach within cognitive psychology that integrates individual differences, experimental, and training frameworks, this project expects to generate new theoretical knowledge about attentional re-scaling and its possible improvement. The expected outcomes include selection and training programs for specific contexts such as training athletes and flight attendants. Economic benefits can be expected through the identification of those who will benefit most from training (reducing waste) and developing cost-effective forms of training which improve task performance.Read moreRead less
Form and motion interactions in human motion perception. Vision works efficiently to detect the motion of both ourselves and other objects by combining motion and pattern information. This project will determine how the visual system achieves this and also create a detailed model that will be directly applicable to areas ranging from clinical neuropsychology to the analysis and design of visual displays.

Summary
The temporal dynamics of conscious object perception . We live in a constantly changing visual world. Thus a key inferential challenge that the human brain must solve is whether ongoing visual input represents a single object varying over time (for example, one person moving through a scene), or two distinct objects (for example, two different people successively occupying the same location). This project will investigate, for the first time, how the brain optimises this inference by using infor ....The temporal dynamics of conscious object perception . We live in a constantly changing visual world. Thus a key inferential challenge that the human brain must solve is whether ongoing visual input represents a single object varying over time (for example, one person moving through a scene), or two distinct objects (for example, two different people successively occupying the same location). This project will investigate, for the first time, how the brain optimises this inference by using information about context, whether the flexibility of the inference process reduces with ageing, and the role of the two main visual pathways in this inference. This will enhance our knowledge of this fundamental process in vision, and our ability to promote optimal functioning into later life.Read moreRead less
Just add noise: the benefits of neural and stimulus noise for perception. This project aims to improve visual perception by maximising the beneficial effects of neural and stimulus noise, i.e. stochastic resonance (SR). SR challenges conventional thinking that noise decreases performance. We expect to reveal the underlying mechanisms using experimental and computational approaches. This project is expected to generate unprecedented insights into how noise influences brain processing, leading to ....Just add noise: the benefits of neural and stimulus noise for perception. This project aims to improve visual perception by maximising the beneficial effects of neural and stimulus noise, i.e. stochastic resonance (SR). SR challenges conventional thinking that noise decreases performance. We expect to reveal the underlying mechanisms using experimental and computational approaches. This project is expected to generate unprecedented insights into how noise influences brain processing, leading to a possible re-evaluation of the function of noise in the brain. Expected outcomes include protocols to optimise human performance through SR, and an augmented reality set-up to apply SR to real-world settings. Economic and social benefits include the ability to individually optimise performance in visual tasks using noise.Read moreRead less

This project aims to create the next generation of experts in Australia’s policing and national security agencies, by improving crime scene evidence interpretation. Agencies are under pressure to develop more rigorous training practices that go beyond mere intuition and tradition. This project will use a novel approach that directs learning toward the most diagnostic perceptual cues. Expected outcomes include a solid empirical basis for national training programs designed to create experts that are accurate, reliable, and continuously improving. Improving the training of experts will ensure the integrity of forensics as evidentiary tools available to police, lead to more reliable courtroom convictions and help safeguard Australia from terrorism and crime.Read moreRead less
How human vision separately determines object and scene motion. This project aims to enhance understanding of how people process visual scenes containing multiple moving objects of interest. The project intends to measure human visual performance to determine how the brain processes multiple motion signals simultaneously. Expected outcomes include an increased understanding of how we are able to use an evolving visual scene to distinguish between changes due to self-motion and those due to the m ....How human vision separately determines object and scene motion. This project aims to enhance understanding of how people process visual scenes containing multiple moving objects of interest. The project intends to measure human visual performance to determine how the brain processes multiple motion signals simultaneously. Expected outcomes include an increased understanding of how we are able to use an evolving visual scene to distinguish between changes due to self-motion and those due to the motion of multiple moving objects such as crowded city footpaths and busy roads. The results will improve our understanding of failures to see moving objects in challenging viewing conditions (for example, high density traffic), and inform work in the design of autonomous driving and augmented reality display systems.Read moreRead less
