Determining the role of disease avoidance in stigmatisation. The aim of this project is to test a disease avoidance model of stigmatisation. Stigmatisation is characterised by chronic avoidance of a person(s) by other people. Infectious disease may produce an apparently similar form of isolation—disease avoidance. This project proposes that many forms of stigmatisation reflect the activation of this disease avoidance system, which is predisposed to respond to signs of disease, irrespective of th ....Determining the role of disease avoidance in stigmatisation. The aim of this project is to test a disease avoidance model of stigmatisation. Stigmatisation is characterised by chronic avoidance of a person(s) by other people. Infectious disease may produce an apparently similar form of isolation—disease avoidance. This project proposes that many forms of stigmatisation reflect the activation of this disease avoidance system, which is predisposed to respond to signs of disease, irrespective of their accuracy. This will represent a significant shift in thinking about this issue and aims to provide the first empirically based model of stigmatisation as an evolved disposition that causes the exclusion of people who look like they may carry an infectious disease - even if they do not.Read moreRead less
A behaviour-genetic study of the National Assessment Program - Literacy and Numeracy (NAPLAN) results. The National Assessment Program - Literacy and Numeracy (NAPLAN) tests are designed by educational authorities, are objective, and have been administered Australia-wide since 2008 so are unquestionably the most valuable national database on school achievement available. This project's twin studies of this data will provide a more solid base for public policy debates on educational policy and pr ....A behaviour-genetic study of the National Assessment Program - Literacy and Numeracy (NAPLAN) results.

Mapping the learning mechanisms linking adversity with maladjustment. Exposure to adversity, such as violence, neglect and natural disasters, is common and a powerful risk factor for emotional maladjustment. Yet knowledge of the underlying mechanisms linking adversity with emotional maladjustment is remarkably limited. By drawing from theories of adversity and learning and utilising novel experimental methodology, this project aims to map how adverse experiences have different negative effects o ....Mapping the learning mechanisms linking adversity with maladjustment. Exposure to adversity, such as violence, neglect and natural disasters, is common and a powerful risk factor for emotional maladjustment. Yet knowledge of the underlying mechanisms linking adversity with emotional maladjustment is remarkably limited. By drawing from theories of adversity and learning and utilising novel experimental methodology, this project aims to map how adverse experiences have different negative effects on daily emotional wellbeing by disrupting the mechanisms underlying how people learn to acquire and reduce reactivity to new threats. Expected benefits include new knowledge about the pathways linking adversity with psychopathology as well as the vital evidence-base for clear targets for behavioural interventions.

Modelling and manipulating brain network dynamics across the lifespan. This project aims to integrate advanced computational modelling and state-of-the-art recording techniques to generate new knowledge on the neural basis of ageing. People are said to grow wiser as they grow older, though more likely they will experience cognitive slowing and reduced memory functions that interfere with their daily lives. The anticipated goal of the project is to develop techniques to predict the personalised e ....Modelling and manipulating brain network dynamics across the lifespan. This project aims to integrate advanced computational modelling and state-of-the-art recording techniques to generate new knowledge on the neural basis of ageing. People are said to grow wiser as they grow older, though more likely they will experience cognitive slowing and reduced memory functions that interfere with their daily lives. The anticipated goal of the project is to develop techniques to predict the personalised effects of brain stimulation on the ageing brain. The outcomes of this research could significantly improve understanding of brain ageing, and advance the fields of systems neuroscience, network science, and brain stimulation.Read moreRead less
The role of early testosterone and brain laterality in language development. The aim of the project is to provide key insights into how foetal hormone exposure and early brain growth support child language. The specialisation of the left cerebral hemisphere for language function is considered critical to supporting the complexity of human language. There is evidence of sex differences in patterns of brain specialisation, which has led to popular but unsubstantiated hypotheses linking prenatal te ....The role of early testosterone and brain laterality in language development. The aim of the project is to provide key insights into how foetal hormone exposure and early brain growth support child language. The specialisation of the left cerebral hemisphere for language function is considered critical to supporting the complexity of human language. There is evidence of sex differences in patterns of brain specialisation, which has led to popular but unsubstantiated hypotheses linking prenatal testosterone and language development. The project aims to explore this by using innovative neuroimaging, endocrine and genetic techniques to track neurodevelopment longitudinally from prenatal life to three years of age. An important aspect of the project is the anticipated refinement of innovative methods for measuring early human development.Read moreRead less
Testing theoretical models of age and disease related changes to inform prevention. Pathological brain changes associated with future cognitive decline become detectable in the 40s or earlier. Yet little is known about what constitutes normal brain ageing in mid-life. Using a number of neuroimaging and epidemiological techniques this project will scrutinise brain and cognitive ageing in middle-age and their significance.
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
The ageing brain: plasticity and training. This project will investigate how the capacity of a person's brain for reorganisation (plasticity) influences cognitive and motor function and training benefits in older adults. The findings will support new training initiatives to promote brain health and well-being across the lifespan.
Do family environments influence children's brain development during the transition to adolescence? Late childhood marks the first stages of a wave of brain growth and reorganisation, second only to infancy in terms of its extent and significance. This project will investigate whether brain development during this period is affected by parenting behaviours, which will ultimately inform early intervention and prevention efforts.
Cognitive flexibility from adolescence to senescence: variability associated with cognitive strategy and brain connectivity. Healthy living in our complex and unpredictable world depends on the ability to flexibly adjust to novelty and change. This project will study how cognitive flexibility changes from adolescence to senescence, identify the brain networks that mediate this change and explore the implications for successful adaptation in everyday life.
