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.

Enhancing emotion knowledge in pre-schoolers with disruptive behaviour: the role of mother-child emotion talk. How can the mother of a disruptive son help him deal better with his anger and fears? The research identifies aspects of mother-child emotion talk that influence the child's ability to understand negative emotions. It assesses if mothers can alter their emotion talk with their children to improve their child's emotion knowledge and behaviour.
The cognitive basis of resilience. This project aims to test whether resilience to bad events can be influenced by modifying information processing factors. High resilience reflects the ability to sustain adaptive psychological functioning in the wake of bad events, and affects physical, emotional, social, and economic wellbeing. The project will test the hypothesis that biases in attention and implicational inferencing at differing stages of event processing affect wellbeing. It will use cognit ....The cognitive basis of resilience. This project aims to test whether resilience to bad events can be influenced by modifying information processing factors. High resilience reflects the ability to sustain adaptive psychological functioning in the wake of bad events, and affects physical, emotional, social, and economic wellbeing. The project will test the hypothesis that biases in attention and implicational inferencing at differing stages of event processing affect wellbeing. It will use cognitive methodologies that sensitively assess and manipulate biases, thereby revealing their causal role in the determination of resilience. The findings are expected to directly contribute to national efforts to build healthy and resilient communities.Read moreRead less
The impact of motherhood on fear extinction in rats. This project aims to identify how motherhood, a time of significant hormonal flux, alters the mechanisms underlying fear regulation in female rats. Current theories of fear regulation are limited because they have been derived from studies that have focused on males but recent work suggests that sex hormones influence fear regulation. The expected outcomes of this project will help to develop a more ecologically valid model of fear regulation ....The impact of motherhood on fear extinction in rats. This project aims to identify how motherhood, a time of significant hormonal flux, alters the mechanisms underlying fear regulation in female rats. Current theories of fear regulation are limited because they have been derived from studies that have focused on males but recent work suggests that sex hormones influence fear regulation. The expected outcomes of this project will help to develop a more ecologically valid model of fear regulation that accounts for fluctuations in female sex hormones and reproductive experience. This should provide unique insights into fear reduction and protection against anxiety.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.
Memory consolidation - Integrating cognitive science and neuroscience approaches to how we remember and how we forget. How can we forget what happened yesterday, but vividly remember our first kiss? Neuroscientists think the brain has a special mechanism to strengthen memories with time, but many psychologists disagree. The project aims to bring the brain and the mind closer together, using the cutting-edge combination of brain imaging and psychological modelling.
The extinction of human fear. Excessive fear negatively impacts the lives of many Australians - so how can we increase the effectiveness of exposure based treatments to reduce human fear? The present basic research will investigate the process thought to underlie exposure-based treatments, extinction of human fear learning, in order to answer this applied question.
Placing prediction into the fear circuit. How do we predict danger in our world? This project will identify the psychological mechanisms and brain pathways that allow us to learn to fear and to also overcome fear when it becomes pathological.
Understanding the emotional brain in risk for depression. The burden of illness due to depression is enormous; family disruption, lost productivity and a high healthcare spend. There are no objective ways to target who will benefit most from preventative programs. This study will detail for the first time how genetic risk may develop into overt depression due to effects on emotional brain systems.
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.
