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
Mental imagery and visual working memory. Remembering information “in mind” is severely limited by restrictions in capacity, duration and precision. The limits on capacity and precision in visual working memory remain unclear. Likewise, the search for the neural correlates of visual working memory has produced conflicting results. This proposal will show that the limits in precision, capacity and the neural correlates of visual working memory are driven by visual mental imagery. By showing that ....Mental imagery and visual working memory. Remembering information “in mind” is severely limited by restrictions in capacity, duration and precision. The limits on capacity and precision in visual working memory remain unclear. Likewise, the search for the neural correlates of visual working memory has produced conflicting results. This proposal will show that the limits in precision, capacity and the neural correlates of visual working memory are driven by visual mental imagery. By showing that mental imagery is the missing link to a comprehensive understanding of working memory, This project will show that mental imagery strength limits how much visual information can be held "in mind”. This work will unify two heated scientific debates and produce a complete map of working memory.Read moreRead less
Poor social functioning in schizophrenia: understanding its causes and developing better treatments. This project will advance knowledge of the thinking processes and the associated neural changes that cause the lifelong social disability which characterises schizophrenia. Findings will, in turn, contribute to better identifying young people, at risk of developing schizophrenia, and inform the design of new interventions and treatments.
Moral reasoning and mental illness: towards a model of moral judgment and moral accountability. This research examines capacities for moral judgment in people with schizophrenia, some of whom act on their delusional beliefs and commit crimes. Findings will, in turn, inform legal and philosophical consideration of the moral accountability of mentally ill defendants, and advance theoretical knowledge of healthy moral decision making.

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

Do physical activity and electronic screen behaviours influence cognitive and psychosocial development in preschool children? Levels of physical inactivity and screen-based entertainment are alarmingly high among preschool children, yet little is known about the independent effects of these behaviours on cognitive and psychosocial development during early childhood.

Levels of physical inactivity and screen-based entertainment are alarmingly high among preschool children, yet little is known about the independent effects of these behaviours on cognitive and psychosocial development during early childhood. This project will investigate the associations between physical activity and screen-based entertainment and cognitive and psychosocial development in preschool children. The findings will identify how much and which types of these behaviours influence developmental outcomes in young children. This knowledge will benefit parents, educators, health professionals and governments to develop and implement evidence-based strategies and policies to give young children the best start in life.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
