Overinvolved and overcontrolling parenting seems to be on the rise as families are confronted with an unsteady world. This project aims to investigate how overparenting affects youth's achievements and well-being as they transition out of secondary school, and will isolate societal and cultural determinants of overparenting. This project will generate new knowledge on family influences on youth's progress, and will substantially contribute to an existing multinational study to identify macro social-cultural determinants of overcontrolling parenting. Expected outcomes are the generation of new knowledge relevant to family policy and practice within Australia, growth in cross-national collaborations, and new theories and methods.Read moreRead less

How satiation control reward value and cue-induced appetitive behaviours. This proposal aims to identify mechanisms that control environment-driven food-seeking behaviours. It seeks to do so by using modern virally-mediated and basic behavioural as well as histological techniques in a transgenic rat to characterise novel hindbrain circuits that control these feeding behaviours. This is significant as environment-driven overeating is problematic yet underlying mechanisms are unclear. This project ....How satiation control reward value and cue-induced appetitive behaviours. This proposal aims to identify mechanisms that control environment-driven food-seeking behaviours. It seeks to do so by using modern virally-mediated and basic behavioural as well as histological techniques in a transgenic rat to characterise novel hindbrain circuits that control these feeding behaviours. This is significant as environment-driven overeating is problematic yet underlying mechanisms are unclear. This project expects to provide new knowledge on when, where and how hindbrain neurons control environment-driven food-seeking behaviours. This should provide benefits to the advancement of knowledge on the neural mechanisms of food-seeking and provide a basic science platform for future research on the study of feeding behaviours.

Hippocampal regulation of goal-directed decision-making. The hippocampus is a part of the brain that is central to learning and memory yet little is known about its role in decision-making. It is the aim of this application to provide the first detailed, causal evidence of hippocampal regulation of decision-making. This is significant because many mental health disorders and dementias that involve decision-making deficits are characterised by hippocampal dysfunction, but any direct link between ....Hippocampal regulation of goal-directed decision-making. The hippocampus is a part of the brain that is central to learning and memory yet little is known about its role in decision-making. It is the aim of this application to provide the first detailed, causal evidence of hippocampal regulation of decision-making. This is significant because many mental health disorders and dementias that involve decision-making deficits are characterised by hippocampal dysfunction, but any direct link between these factors is unknown. The outcomes of the current grant will provide the first evidence of that link, thus providing deeper understanding of the neurophysiological mechanisms of these disorders, which could eventuate in the creation of more beneficial treatments.

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

For decades, compensation experts have advocated for the use of financial incentives to motivate work performance, yet organisations keep encountering performance issues caused by these incentives. Using agency, expectancy, and self-determination theory to inform a meta-analysis and a series of experiments, this research will help uncover the most important motivational mechanisms that explain how financial incentives influence different types of performance. Given that compensation accounts for an important proportion of an organisation's operating expenses and that employee engagement is on the decline around the world, this research will provide a strong empirical basis to develop more effective compensation systems.Read moreRead less
