Hunger flexibly modifies hypothalamic neural circuits responding to threat. Animal and human behaviour frequently involves a choice between actions or goals with conflicting positive and negative outcomes. However, the appropriate action or goal in conflicting situations often depends on physiological pressures like hunger, stress and mating opportunities. For example, the need for resources within an environment, such as food, drives approach behaviour, whereas threats to survival, such as pred ....Hunger flexibly modifies hypothalamic neural circuits responding to threat. Animal and human behaviour frequently involves a choice between actions or goals with conflicting positive and negative outcomes. However, the appropriate action or goal in conflicting situations often depends on physiological pressures like hunger, stress and mating opportunities. For example, the need for resources within an environment, such as food, drives approach behaviour, whereas threats to survival, such as predator cues, enhance avoidance behaviour. This project will uncover the neural circuitry and endocrine mechanisms through which hunger influences hypothalamic threat-detecting circuits that suppress food intake. These studies provide a new hypothalamic model to understand risk/reward decision in the brain.Read moreRead less

Summary
The effects of parental education on child health outcomes. This project aims to understand how public education policies can improve health. Common economic analysis of returns to education fails to capture the critical secondary beneficial effects of parental education on future generations’ health. These positive effects are systematically undercounted in the cost-benefit analysis of Australia’s investment in education. This project will use Australian datasets and natural experiments to iden ....The effects of parental education on child health outcomes. This project aims to understand how public education policies can improve health. Common economic analysis of returns to education fails to capture the critical secondary beneficial effects of parental education on future generations’ health. These positive effects are systematically undercounted in the cost-benefit analysis of Australia’s investment in education. This project will use Australian datasets and natural experiments to identify how parental education affects the health outcomes of the second generation. This project expects to provide policy recommendations to maximise health, wellbeing and economic outcomes for Australia.Read moreRead less

Summary
Autobiographical memory as a key to successful psychological functioning. 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 funct ....Autobiographical memory as a key to successful psychological functioning. 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
Prospective predictors of body image attitudes and dieting beliefs during first years of school: Providing guidance for prevention. Although it is recognised that body dissatisfaction is a risk factor for the development of a wide range of mental health problems, little is known about its early development. There is a distinct increase in body dissatisfaction and dieting awareness during early school years. However, there has not been an exploration of a wide range of family, media, peer and sch ....Prospective predictors of body image attitudes and dieting beliefs during first years of school: Providing guidance for prevention. Although it is recognised that body dissatisfaction is a risk factor for the development of a wide range of mental health problems, little is known about its early development. There is a distinct increase in body dissatisfaction and dieting awareness during early school years. However, there has not been an exploration of a wide range of family, media, peer and school adaptation variables as predictors of body image and weight change behaviours in both girls and boys. This project will examine prospective predictors of body image and related variables in five to seven years old children. Findings will inform development of prevention interventions to assist parents and schools provide a positive body image and eating environment for Australian children.Read moreRead less
Addressing risk factors of overweight and obesity among adolescents in out-of-home care: The Healthy Eating and Active Living (HEAL) study. The health risk of overweight and obesity when adolescents are placed in out-of-home care has been largely ignored. This project will be the first to evaluate a healthy eating and physical activity obesity prevention/intervention program designed specifically for vulnerable and disadvantaged adolescents living in out-of-home residential care.
The impact of female sex hormones on neurodevelopment. This project aims to characterise the contribution of sex hormones to the development of emotional brain circuits in female adolescents. Puberty is associated with profound changes in emotional behaviours in females, but we know little about the underlying brain mechanisms. In particular, research has neglected to consider the role of the sex hormones for which changes are a defining feature of female puberty (eg, oestradiol). This work will ....The impact of female sex hormones on neurodevelopment. This project aims to characterise the contribution of sex hormones to the development of emotional brain circuits in female adolescents. Puberty is associated with profound changes in emotional behaviours in females, but we know little about the underlying brain mechanisms. In particular, research has neglected to consider the role of the sex hormones for which changes are a defining feature of female puberty (eg, oestradiol). This work will be the first to comprehensively advance our understanding of the unique role of sex hormones in shaping the adolescent female brain. It will provide critical understanding of how individual differences in hormonal factors increase risk for emotional problems in females, and inform treatment strategies.Read moreRead less
The cost of keeping gruesome images from the world. This project aims to investigate one of society’s most invisible ‘frontline’ trauma workforces—the online content moderators responsible for limiting the public’s exposure to distressing and sensitive content on social media. Using a series of rigorous experiments, and cutting-edge psychological and physiological assessment techniques, the research will advance our understanding of the impact of indirect trauma on mental health. Expected outcom ....The cost of keeping gruesome images from the world. This project aims to investigate one of society’s most invisible ‘frontline’ trauma workforces—the online content moderators responsible for limiting the public’s exposure to distressing and sensitive content on social media. Using a series of rigorous experiments, and cutting-edge psychological and physiological assessment techniques, the research will advance our understanding of the impact of indirect trauma on mental health. Expected outcomes include novel empirical evidence for preventative strategies that will predict, monitor and reduce negative mental health outcomes. This will provide significant global benefits to people with indirect trauma experiences, such as defence and forensic personnel.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.
A social psychology of affective disturbance. We are in the midst of a depression and anxiety epidemic that cannot be explained by focusing on individual experiences alone. We desperately need to understand the cultural contributors to depression and anxiety, thereby providing insight into the epidemiology of these conditions. Drawing on experimental studies, longitudinal sampling of daily emotional experiences, and multi-national data, the research will show how cultural contexts may exacerbate ....A social psychology of affective disturbance. We are in the midst of a depression and anxiety epidemic that cannot be explained by focusing on individual experiences alone. We desperately need to understand the cultural contributors to depression and anxiety, thereby providing insight into the epidemiology of these conditions. Drawing on experimental studies, longitudinal sampling of daily emotional experiences, and multi-national data, the research will show how cultural contexts may exacerbate individual-level affective disturbance and demonstrate the processes through which occurs. The findings will make a timely and much needed contribution to public policy decisions and preventive health care.Read moreRead less
Mapping, understanding and manipulating the human brain connectome with MRI. The human brain is an extraordinarily complex network, comprising millions of nerve cells connected by trillions of fibres. Understanding this intricate web of connectivity – the so-called human connectome – has become a central goal of neuroscience and is comparable in scale to the human genome project. This project will develop new brain imaging methods for accurately mapping the connectome. It will investigate how in ....Mapping, understanding and manipulating the human brain connectome with MRI. The human brain is an extraordinarily complex network, comprising millions of nerve cells connected by trillions of fibres. Understanding this intricate web of connectivity – the so-called human connectome – has become a central goal of neuroscience and is comparable in scale to the human genome project. This project will develop new brain imaging methods for accurately mapping the connectome. It will investigate how information is communicated between its different regions and how individual differences in brain network function relate to our genetic make-up. It will also determine whether we can manipulate the function of specific circuits of the connectome in a targeted way, in the hope of developing new treatments for brain disorders.Read moreRead less
