Summary
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. This project will investigate the associations between physical activity and screen-based entertainment and cognitive and psychosoc ....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. 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
Uncertainty and response control in the prefrontal cortex. This project will identify how complex behaviours come to be performed habitually. It is proposed that statistical certainty in the learning environment is a key determinant of automatic behaviour, that detection of uncertainty can restore voluntary control of behaviour and that this is an important function of the prefrontal cortex of the brain.

Summary
Effects of reducing sitting on toddlers’ executive functions: Cluster RCT. The levels of sedentary behaviour are now alarmingly high in toddlers, yet little is known about the effect of this behaviour on cognitive development and executive functions during early childhood. This 15 month cluster randomised controlled trial will examine the effects of reduced sitting time on cognitive development and executive functions in Australian toddlers from low socio-economic families. This project aims to ....Effects of reducing sitting on toddlers’ executive functions: Cluster RCT. The levels of sedentary behaviour are now alarmingly high in toddlers, yet little is known about the effect of this behaviour on cognitive development and executive functions during early childhood. This 15 month cluster randomised controlled trial will examine the effects of reduced sitting time on cognitive development and executive functions in Australian toddlers from low socio-economic families. This project aims to develop and implement evidence-based strategies and policies designed to optimise developmental and health outcomes in young children, specifically in those from a low socio-economic status, thus giving young children the best start in life.Read moreRead less
The NSW child development study. Research shows that a child's development predicts health and social outcomes later in life. This Australian project will be the first to identify risk and protective factors associated with these outcomes in 87,000 children from birth to 10 years. The results will help inform governments to improve our children's health and educational achievements.
The Power of Causal Attributions: Genetic Essentialist Biases and Health. Great advancements in the science of genetics are accompanied by increased public propensity to attribute causality to the genes for diverse outcomes such as abilities, social group differences, attitudes, and diseases. These genetic attributions activate cognitive biases termed Genetic Essentialist Biases, which have been shown to instigate a variety of deleterious outcomes. The project will evaluate hypothesized detrimen ....The Power of Causal Attributions: Genetic Essentialist Biases and Health. Great advancements in the science of genetics are accompanied by increased public propensity to attribute causality to the genes for diverse outcomes such as abilities, social group differences, attitudes, and diseases. These genetic attributions activate cognitive biases termed Genetic Essentialist Biases, which have been shown to instigate a variety of deleterious outcomes. The project will evaluate hypothesized detrimental effects of genetic attributions on actual health behaviours, endorsement of health policies, and disease related stigma. Furthermore, it will test interventions designed to reduce the negative effects of such attributions on attitudes, beliefs, intentions, and behaviours related to a common disease. Read moreRead less
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
