Towards a cognitive process model of how attention and choice interact. Before making any decision, we must gather information on what options are available. This process may influence the choices we make: if we do not notice an option, we will not choose it even if it would have been valuable. This project aims to examine how prior experience can produce attentional biases that influence decisions, and will develop a new computational model of this interaction of attention and choice as an outc ....Towards a cognitive process model of how attention and choice interact. Before making any decision, we must gather information on what options are available. This process may influence the choices we make: if we do not notice an option, we will not choose it even if it would have been valuable. This project aims to examine how prior experience can produce attentional biases that influence decisions, and will develop a new computational model of this interaction of attention and choice as an outcome. This new knowledge will enhance the world-class status of Australian cognitive psychology. Moreover, it should provide significant benefits through improving our ability to predict and shape behaviour, and shedding light on the role of biases in healthy cognition and in the context of compulsive behaviours.Read moreRead less

This project aims to develop the first-ever set of explanatory principles for how people successfully retain and retrieve individual episode memories from repeated experiences (e.g., one occurrence of a routine social encounter or job-related activity). By deepening our understanding of how memory works, this new knowledge is expected to lay the foundation for interview guidance and ongoing research aimed at enhancing the proficiency of investigations into matters that rely on detailed and accurate accounts of specific episodes. This includes workplace or traffic accident investigations, infectious disease contact tracing, as well as prosecution of repeated sexual offences.Read moreRead less
Human Scheduling of Perceptual Tasks. This project aims to develop a novel approach for synthesising how people prioritise information with theories of attention and decision making. Characterising inefficient scheduling in the tradeoff between the difficulty and the cost/benefit of different subtasks will allow the development of a formal computional model that generalises statistical models of rank order data to a theory of the timing of scheduling decisions and task completions. Outcomes incl ....Human Scheduling of Perceptual Tasks. This project aims to develop a novel approach for synthesising how people prioritise information with theories of attention and decision making. Characterising inefficient scheduling in the tradeoff between the difficulty and the cost/benefit of different subtasks will allow the development of a formal computional model that generalises statistical models of rank order data to a theory of the timing of scheduling decisions and task completions. Outcomes include benchmark data from a novel paradigm for studying perceptual decisions and behavior and a model which can explain and predict human scheduling. This project aims to benefit industry by allowing for the simulation of information prioritisation by human agents in complex environments.Read moreRead less

Summary
Is degradation of photovoltaic modules predictable and preventable? This project aims to determine the fundamental properties of the hydrogen related defect causing degradation of commercial solar modules and develop models to predict its impact. The defect causes up to 16% power loss and is likely to affect all photovoltaics due to the universal behaviour of hydrogen in semiconductors. Through new techniques combining deuterium (heavy hydrogen) and machine learning, the key project outcomes are ....Is degradation of photovoltaic modules predictable and preventable? This project aims to determine the fundamental properties of the hydrogen related defect causing degradation of commercial solar modules and develop models to predict its impact. The defect causes up to 16% power loss and is likely to affect all photovoltaics due to the universal behaviour of hydrogen in semiconductors. Through new techniques combining deuterium (heavy hydrogen) and machine learning, the key project outcomes are new knowledge of hydrogen behaviour, mitigation of degradation and predictive models to test and forecast the future output of affected modules. This is critical for system design and reliability, manufacturer warranty terms, investor returns, consumer confidence, and ultimately mitigating the climate crisis.Read moreRead less

This project aims to improve the quality of information provided by eyewitnesses, and the ability of police officers and triers of fact (e.g., juries, judges) to evaluate this information. Laboratory investigations will determine how best to test memory and confidence to achieve this aim. A new class of cognitive models will provide a unified account of response accuracy, response time ....Improving the diagnosticity of eyewitness memory choices. Eyewitness identification error is common and costly. This project aims to improve the quality of information provided by eyewitnesses, and the ability of police officers and triers of fact (e.g., juries, judges) to evaluate this information. Laboratory investigations will determine how best to test memory and confidence to achieve this aim. A new class of cognitive models will provide a unified account of response accuracy, response time, and confidence, suitable for application to computerized testing scenarios. The models and testing methods validated in the laboratory will be refined for application in eyewitness memory settings, facilitating better evaluation of identification evidence, and potentially reducing wrongful convictions.Read moreRead less
Combating Misinformation – Designing a Toolkit to Address a Global Problem. Misinformation impairs people’s cognition – their memory, reasoning and judgements – even if credible corrections are issued; it therefore poses a significant threat to evidence-based practice and policy.

Misinformation impairs people’s cognition – their memory, reasoning and judgements – even if credible corrections are issued; it therefore poses a significant threat to evidence-based practice and policy. This project aims to develop novel psychological interventions to reduce the impact of misinformation, based on an experimental research program designed to systematically assess the effects of various types of misinformation on cognition and behaviour. The expected outcome is the development of new knowledge regarding misinformation processing and communication and its translation into a toolkit for practical application. This promises to improve individual and public decision making and foster a culture of accurate information exchange.Read moreRead less

Investigating the role of Zona Incerta RXFP3+ cells in learning and memory. Learning and memory are fundamental to human and animal behaviour. We identified a specific population of cells in the zona incerta of the brain, where activation inhibits expression of memory, and facilitates the acquisition of new learning. Aside from our observations, nothing is currently known about the anatomy and function of these cells. This project aims to map how they connect to the rest of the brain, to observe ....Investigating the role of Zona Incerta RXFP3+ cells in learning and memory. Learning and memory are fundamental to human and animal behaviour. We identified a specific population of cells in the zona incerta of the brain, where activation inhibits expression of memory, and facilitates the acquisition of new learning. Aside from our observations, nothing is currently known about the anatomy and function of these cells. This project aims to map how they connect to the rest of the brain, to observe how these connections are recruited during learning and memory, and then to test their function experimentally. The outcomes will extend the known neural circuitry that controls learning by defining how and where these unexplored pathways fit within it; thus advancing knowledge regarding neural regulation of behaviour.
