Neuronal and behavioural correlates of sensory adaptation. Sensory systems adapt to the statistics of their environment, and the consequences of this adaptation are evident in neuronal activity and in animal’s behaviour. This project will employ a novel paradigm to characterise how adaptation changes the response properties of individual sensory neurons to improve efficiency of information transmission.
Fake News and Post-Truth Impacts: Responses to Conflictive Uncertainty. Attributions of fake news and post-truth are symptoms of uncertainty arising from conflicting information. Little is known about human responses to conflictive uncertainty other than that people find it aversive. This project aims to identify the determinants of human attitudes towards conflictive uncertainty. The aims will be achieved via the development of measures of attitudes toward conflictive uncertainty, and studies i ....Fake News and Post-Truth Impacts: Responses to Conflictive Uncertainty. Attributions of fake news and post-truth are symptoms of uncertainty arising from conflicting information. Little is known about human responses to conflictive uncertainty other than that people find it aversive. This project aims to identify the determinants of human attitudes towards conflictive uncertainty. The aims will be achieved via the development of measures of attitudes toward conflictive uncertainty, and studies identifying the major influences thereof. Expected outcomes include advances in knowledge of how conflictive uncertainty attitudes relate to risk orientations, personality, and situational factors. Anticipated benefits include improved strategies for decision makers and communicators faced with conflictive uncertainty.Read moreRead less

This project aims to develop a comprehensive psychological framework and effective measures for assessing attitudes to ambiguity. Using empirical work and quantitative modelling, it will address the multidimensional nature of ambiguity, and likely individual and cultural differences. Attitudes to ambiguity strongly influence people's judgments and the expected outcomes from this project will enhance theoretical understandings and measurement tools for psychological research in decision making. This project aims to provide significant benefits by developing novel strategies for improving decision making in contexts of ambiguity.Read moreRead less
Role of form information in motion processing. The study of the mind, and its relationship to the brain, is currently at the forefront of new developments in science. 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.

The study of the mind, and its relationship to the brain, is currently at the forefront of new developments in science. 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
