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.

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
A comprehensive framework for modelling the human connectome. The human brain is an extraordinarily complex network of interconnected cells. This project aims to use mathematical modelling and brain imaging to uncover key principles of network wiring in the human brain. Using an interdisciplinary approach that combines elements of neuroscience, genetics, physics, and psychology, the project will result in a new, rigorous framework for testing competing theories of brain development, the identifi ....A comprehensive framework for modelling the human connectome. The human brain is an extraordinarily complex network of interconnected cells. This project aims to use mathematical modelling and brain imaging to uncover key principles of network wiring in the human brain. Using an interdisciplinary approach that combines elements of neuroscience, genetics, physics, and psychology, the project will result in a new, rigorous framework for testing competing theories of brain development, the identification of key wiring principles for developing brains, and an understanding of how these principles shape behaviour. This work will shed new light on the developmental processes that underlie human behaviour and disease.Read moreRead less
Mapping cognitive impulsivity through online testing. The project aims to develop a new model of cognitive impulsivity and produce an online tool to measure it. Impulsivity is defined as the skill/s that exert control over impulsive behaviours. It is a trait of human cognition that affects health and productivity and that varies normatively across the healthy population. However, coherent models of cognitive impulsivity and comprehensive measures of the construct are lacking. The project aims to ....Mapping cognitive impulsivity through online testing.

It is a trait of human cognition that affects health and productivity and that varies normatively across the healthy population. However, coherent models of cognitive impulsivity and comprehensive measures of the construct are lacking. The project aims to unravel and measure the cognitive skills that can produce (or avoid) impulsive behaviour.Read moreRead less
Assessment of circadian and light interactions in adolescent sleepiness. This project aims to examine the relative contributions of multiple biological clock and sleep factors that may be linked to cognitive function and sleepiness in adolescents. Over 70 per cent of adolescents in Australia experience insufficient sleep. Cross-sectional studies have shown that insufficient sleep and mistimed sleep lead to reduced cognitive function. The project intends to identify specific sleep and circadian m ....Assessment of circadian and light interactions in adolescent sleepiness. This project aims to examine the relative contributions of multiple biological clock and sleep factors that may be linked to cognitive function and sleepiness in adolescents. Over 70 per cent of adolescents in Australia experience insufficient sleep. Cross-sectional studies have shown that insufficient sleep and mistimed sleep lead to reduced cognitive function. The project intends to identify specific sleep and circadian markers that are linked to academic performance, and generate innovative algorithms that predict these associations. The project will provide new knowledge to drive prevention and early intervention programs that use sleep-wake and light exposure information to improve sleep quality.Read moreRead less
A theory of attention and decision-making in multi-attribute and multi-object perceptual judgements. The human brain is an efficient biological computation device for rapidly translating perception into action. This project will develop and test a mathematical model of the processes of visual selective attention and perceptual decision-making. These processes are at the heart of the brain's ability to carry out this translation in a fast and accurate way.
Computational neuroanatomy: analysis of neural connections in the primate brain. This project will map the full network of connections between brain cells, using a computer graphics database that will consolidate data from hundreds of experiments. This will allow the first realistic simulations of neural activity, and will provide new insights about the structure and function of the nervous system.
From fluid intelligence to crystallised expertise: an integrative Bayesian approach. Intelligence is correlated with learning but uncorrelated with most aspects of expertise. Why is this so? Why does the role of intelligence diminish as one becomes more expert at a task? This project examines a broad range of cognitive tasks to provide a concise mathematical description of how intelligence relates to expertise.

Summary
Wandering minds in sleep and wakefulness: Attention, consciousness, self. This project aims to develop a theory of mind wandering. A large portion of our conscious lives is spent mind wandering: attention periodically drifts away from current tasks, often without our noticing. This challenges the assumption that healthy adults are normally aware of and able to control their thought processes. This project will use cognitive neuroscience, sleep and dream research and philosophy of mind to develop ....Wandering minds in sleep and wakefulness: Attention, consciousness, self. This project aims to develop a theory of mind wandering. A large portion of our conscious lives is spent mind wandering: attention periodically drifts away from current tasks, often without our noticing. This challenges the assumption that healthy adults are normally aware of and able to control their thought processes. This project will use cognitive neuroscience, sleep and dream research and philosophy of mind to develop a theory of mind wandering across the sleep-wake cycle and an interdisciplinary methodology for its investigation. The anticipated outcome is understanding of spontaneous thought and its relationship to attention, consciousness and the self. This potentially throws new light on important issues relating to mental health and sleep disorders.Read moreRead less
The intergenerational origins of social and emotional wellbeing. This project aims to map inter-generational pathways that connect parental life histories, from infancy to parenthood, to offspring development decades later. The project brings together rare data from three long running studies of social development in Australia and New Zealand: The Australian Temperament Project (est. 1983), The Victorian Inter-generational Health Cohort (est. 1992), and The Dunedin Multidisciplinary Health & Dev ....The intergenerational origins of social and emotional wellbeing.

Expected outcomes include enhanced understanding of the factors that strengthen or undermine well-being in families from one generation to the next.Read moreRead less
Humans as animals and objects: the psychology of dehumanisation. This project will clarify how some individuals and groups as perceived as less than human. It will examine how some groups are subtly seen as animal-like and how some media images objectify individuals. It will yield a deeper understanding of how people may be degraded, dismissed, vilified and dehumanised.
