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
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
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.
Multiscale and multimodal modelling of brain dynamics. This project aims to understand dynamics of how several brain regions work together to process information. This project will generate new knowledge in brain sciences by using state of the art computational modelling and neuroimaging methods like functional and diffusion magnetic resonance imaging and electromagnetic measurements. This project will develop technologies to compute multiscale, multimodal and directed connectivity in the brain. ....Multiscale and multimodal modelling of brain dynamics.

This project will develop technologies to compute multiscale, multimodal and directed connectivity in the brain. Expected outcomes of this project will enhance our understanding of the brain’s functional organization and dynamics. The benefits of this project will include breakthroughs in development of new neuro-technologies like brain-machine interfaces and neuroscience inspired artificial intelligence. Read moreRead less

Summary
Information processing in the brain. This project aims to understand the brain's functional organisation by developing non-invasive methods to characterise connectivity between interacting brain regions. No model-based methods to compute directional coupling between brain regions can be applied to large scale networks for resting state functional MRI data. This capability would be a major breakthrough in neuroimaging, given uninformative (non-directional) network connectivity analysis restricts ....Information processing in the brain. This project aims to understand the brain's functional organisation by developing non-invasive methods to characterise connectivity between interacting brain regions. No model-based methods to compute directional coupling between brain regions can be applied to large scale networks for resting state functional MRI data. This capability would be a major breakthrough in neuroimaging, given uninformative (non-directional) network connectivity analysis restricts research. This project is expected to advance our understanding of information processing in the brain by providing a mechanistic approach to functional integration.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
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
