Advancing the science of willpower: investigating the mechanisms and processes of self-control. Willpower or 'good' self control is important for success in our academic, occupational, and social lives. This project will use cutting-edge scientific methods to investigate how glucose, the primary fuel for body function, promotes 'good' self-control and stimulates regions in the brain important for self-control.

The whole is greater than its parts: Improving rail safety through teamwork. This project seeks to develop a train driving risk model that includes human factors, to enable rail organisations to better identify and mitigate safety risks. Train driving is a cognitively demanding task in which errors can quickly lead to catastrophic consequences. Signals passed at danger (SPADs) occur when a train goes past a red light. Despite significant investment in better signalling and communications infrast ....The whole is greater than its parts: Improving rail safety through teamwork. This project seeks to develop a train driving risk model that includes human factors, to enable rail organisations to better identify and mitigate safety risks. Train driving is a cognitively demanding task in which errors can quickly lead to catastrophic consequences. Signals passed at danger (SPADs) occur when a train goes past a red light. Despite significant investment in better signalling and communications infrastructure, SPAD rates remain unacceptably high and are projected to rise. SPAD risk is currently managed with a retrospective approach that fails to consider non-technical human factors such as time pressure, workload and team communications. By including non-technical dimensions, this project seeks to develop a comprehensive model to explain and prevent SPADs.Read moreRead less
Mechanisms of Recovery after Extinction of Conditioned Behaviour. Old habits die hard and may never die at all. My previous ARC-funded research has revealed that extinguished learning can be recovered rapidly and in unsuspected ways. This project is aimed at building a neural network to explain how old learning can recovered. In practical terms, rapid recovery has both benefits, e.g., our ability to regain old skills with brief refresher training, and costs, e.g., relapse after therapies for anx ....Mechanisms of Recovery after Extinction of Conditioned Behaviour. Old habits die hard and may never die at all. My previous ARC-funded research has revealed that extinguished learning can be recovered rapidly and in unsuspected ways. This project is aimed at building a neural network to explain how old learning can recovered. In practical terms, rapid recovery has both benefits, e.g., our ability to regain old skills with brief refresher training, and costs, e.g., relapse after therapies for anxiety disorders and substance abuse. In theoretical terms, understanding recovery in biological systems will inform research concerning both the neural basis of memory and the design of robots.Read moreRead less
A community based social identity approach to loneliness. Loneliness across Australia is a deep concern. Social prescribing is a novel community-based approach to managing loneliness, however it is unclear when and in what circumstances it is effective. This project aims to test a social identity approach to loneliness, incorporating longitudinal, cross-sectional, and experimental methods to understand how best to engage isolated people in group programs. The expected benefits of this project ar ....A community based social identity approach to loneliness. Loneliness across Australia is a deep concern. Social prescribing is a novel community-based approach to managing loneliness, however it is unclear when and in what circumstances it is effective. This project aims to test a social identity approach to loneliness, incorporating longitudinal, cross-sectional, and experimental methods to understand how best to engage isolated people in group programs. The expected benefits of this project are to produce a validated social prescribing model that can be implemented in multiple settings across Australia in order to reduce loneliness, strengthen communities, and guide more appropriate uses of health services.Read moreRead less

New directions for using brain stimulation to understand brain function. Neuroplasticity is of fundamental importance to brain function as it mediates learning, memory and development. Deficits in neuroplasticity are observed in a number of neurological conditions and thought to contribute to cognitive dysfunction. This study is designed to develop a better understanding of the neurochemical and genetic factors impacting on neuroplasticity. In addition, it aims to (i) upregulate brain connectivi ....New directions for using brain stimulation to understand brain function. Neuroplasticity is of fundamental importance to brain function as it mediates learning, memory and development. Deficits in neuroplasticity are observed in a number of neurological conditions and thought to contribute to cognitive dysfunction. This study is designed to develop a better understanding of the neurochemical and genetic factors impacting on neuroplasticity. In addition, it aims to (i) upregulate brain connectivity in a precise and targeted manner, (ii) elicit functional increases in cognitive performance and (iii) demonstrate the relationship between functional connectivity and cognition. Outcomes include a better understanding of plasticity in the brain & a enhanced capacity to examine and modulate brain plasticity.Read moreRead less

Ageing well in a foreign land. This project aims to enhance well-being among people ageing in a foreign land, by understanding the best approaches to connect them. Older people from diverse cultural backgrounds are socially isolated as they age in a foreign land. This project will use a mixed methods approach to identify the factors that contribute to social isolation and low well-being; understand when and how engagement in ethnocultural and multicultural activities enhances social connectedness and well-being; and evaluate and determine key principles underlying effective identity-based interventions. The intended outcome of the project is a new policy model that builds Australia’s care capacity in tandem with its diverse ageing population.Read moreRead less
Breaking the cycle of homelessness: an identity change approach to enhance resilience and well-being. This project will explore the factors that contribute to the development of well-being and resilience among those who are homeless. We focus on the importance of social connections in enhancing resilience, well-being and breaking the cycle of homelessness. Findings will inform best practice guidelines and policy in emergency accommodation centres.
Antecedents of innovation vs. conservatism in rural industries and communities. This project will investigate antecedents of conservatism and innovation within rural communities and industries. Whilst effort, from government, community and industry, has focussed on social, economic and environmental reform, intended shifts in thinking and practice are frequently not realised. .Personality literature suggests individual differences in conservatism/innovation. Further, people are drawn towards ....Antecedents of innovation vs. conservatism in rural industries and communities. This project will investigate antecedents of conservatism and innovation within rural communities and industries. Whilst effort, from government, community and industry, has focussed on social, economic and environmental reform, intended shifts in thinking and practice are frequently not realised. .Personality literature suggests individual differences in conservatism/innovation. Further, people are drawn towards situations that satisfy intrinsic needs and away from situations that do not. The result may be greater concentrations of particular personality types in conservative industries and communities and a quite different concentration in innovative groups. Validation of this hypothesis would permit more appropriate and effective policy and management strategy.Read moreRead less
A unified theory of performance in absolute identification tasks. The ability to identify stimuli is fundamentally important in human cognition and is studied in absolute identification tasks, where people must identify one out of a number of stimuli, varying on a single dimension, with an appropriate label. A remarkable finding is that people cannot reliably identify more than about seven different stimuli. This limit imposes severe practical restrictions on our ability to categorise stimuli an ....A unified theory of performance in absolute identification tasks. The ability to identify stimuli is fundamentally important in human cognition and is studied in absolute identification tasks, where people must identify one out of a number of stimuli, varying on a single dimension, with an appropriate label. A remarkable finding is that people cannot reliably identify more than about seven different stimuli. This limit imposes severe practical restrictions on our ability to categorise stimuli and constitutes a perplexing problem for cognitive theory. This project involves an international collaborative effort by five leading researchers in mathematical psychology to develop a comprehensive, integrative model of human performance in absolute identification tasks.

Unconscious processing: To what extent, how flexible and how smart? We are unaware of the sophisticated pattern analyses conducted by our perceptual systems that enable us to operate in a complex environment.

We are unaware of the sophisticated pattern analyses conducted by our perceptual systems that enable us to operate in a complex environment. Less clear is whether unconsciously presented information itself can influence our behaviour or indeed whether unconscious cognition occurs. The proposed studies provide the foundation and structure for a pioneering examination of the extent, flexibility and computational power of unconscious processing at the level of neural response and behaviour. The impact and benefits of the project will be in its contribution to theory with outcomes revealing the boundary conditions governing unconscious cognition and providing a first benchmark for how such conditions might vary across the lifespan.Read moreRead less
