The desire for knowledge: Neural mechanisms of information-seeking. This project aims to determine the mechanisms that drive individuals to seek out information, and to characterise the neural processes that underlie how that information is valued. The project tests the idea that information is represented in the brain as a form of reward. The results are expected to contribute significant mechanistic insights at the level of brain and behaviour on the nature of information value.

This project aims to determine the mechanisms that drive individuals to seek out information, and to characterise the neural processes that underlie how that information is valued. The project tests the idea that information is represented in the brain as a form of reward. The results are expected to contribute significant mechanistic insights at the level of brain and behaviour on the nature of information value. This is likely to have wide-ranging implications across multiple domains of human endeavour, including education, work-place efficiency, policy development, and consumer behaviour.Read moreRead less

A Brain-Behaviour Model of Decision-Making Under Distraction. People make thousands of decisions each day, such as judging whether it is safe to cross the street at a busy intersection. This project aims to investigate how decision-making is impacted when a person is temporarily distracted, for example when receiving a text message alert from one’s phone.

People make thousands of decisions each day, such as judging whether it is safe to cross the street at a busy intersection. This project aims to investigate how decision-making is impacted when a person is temporarily distracted, for example when receiving a text message alert from one’s phone. By combining recordings of brain activity with cutting-edge mathematical modelling techniques, this project expects to develop a novel theoretical framework that captures the effects of distraction on brain networks that underpin human decision-making performance. This knowledge should be highly beneficial for developing informed policies that reduce effects of distraction and preserve decision-making capacity in safety critical situations.Read moreRead less

Summary
Impact of shift work on emergency performance, decision making and stress. Sleep and circadian disruptions due to shift work are common for emergency personnel, but their impact on team performance and decision making is poorly understood. Using an ecologically relevant simulated work environment, this project aims to examine how shift work influences work performance and team decision making and identify potential stress-related mechanisms that may underpin impairments in these outcomes. By und ....Impact of shift work on emergency performance, decision making and stress. Sleep and circadian disruptions due to shift work are common for emergency personnel, but their impact on team performance and decision making is poorly understood. Using an ecologically relevant simulated work environment, this project aims to examine how shift work influences work performance and team decision making and identify potential stress-related mechanisms that may underpin impairments in these outcomes. By understanding the role poor sleep and circadian misalignment due to shift work play on work performance, this project will inform industry practices and training approaches designed to optimise workplace safety and emergency performance. This project will benefit emergency personnel and the people who depend on these services.Read moreRead less

This project aims to develop a new framework for understanding how the anatomy of the brain shapes its function and influences individual differences in human behaviour. The project expects to develop innovative methods for mapping and modelling human brain function by combining techniques from neuroscience, physics, informatics, psychology, and genetics. Expected outcomes include new tools for analysing brain imaging data, new models of brain structure and function, an understanding of how genes shape brain architecture, and a comprehensive characterization of how individual differences in brain organization relate to behaviour. These outcomes should benefit our understanding of how the brain works and of the biological basis of behaviour.Read moreRead less

Mapping the genetics of brain connectivity. The brain is a complex biological system that gives rise to our consciousness, thoughts, and experiences, yet we still do not know how this complexity emerges. This project aims to comprehensively investigate the genetics of brain connectivity combining cutting-edge techniques in neuroimaging, genomics, mathematical modelling, and cognitive neuroscience, focusing specifically on the connectivity of functionally important brain network hubs.

This project aims to comprehensively investigate the genetics of brain connectivity combining cutting-edge techniques in neuroimaging, genomics, mathematical modelling, and cognitive neuroscience, focusing specifically on the connectivity of functionally important brain network hubs. The outcomes will provide a mechanistic understanding of the genetic origins of brain network formation and an explanation for how genetic influences on brain organisation shape human behaviour advancing the fundamental knowledge about the complexity of the brain.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

This project aims to develop a theoretical framework that will explain how the retrieval of autobiographical memories may be essential for good mental health. Using cutting-edge statistical techniques, an international team of researchers will track young adults over a number of years to explore whether autobiographical memory retrieval underlies development of both adaptive and dysfunctional aspects of psychological functioning. Expected project outcomes will indicate whether future researchers could enhance autobiographical memory to promote healthy development and potentially prevent mental illness from ever emerging. This will allow future researchers to use cognitive science to benefit the mental health of Australians.Read moreRead less

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

Languages around the world incorporate different systems of categories, and understanding this variation can contribute to a better understanding of similarities and differences between cultures. This project examines how linguistic variation is shaped in part by variation in the local physical and social environment. The methods include computational analyses of large electronic data sets including dictionaries and linguistic corpora that have become available only recently, and psychological experiments that probe the causal mechanisms that lead to variation across languages. The outcomes include computational tools that pick out key differences between languages and therefore support cross-cultural communication.Read moreRead less
