This project aims to investigate the nature of this anxiety and the nature of the stimuli that produce it. The outcomes should be a better understanding of the neural basis and pharmacology of anxiety states and the identification of novel chemicals that have powerful rodent repellent properties. Such chemicals may be of great use in domestic and agricultural contexts where rodents are pests.Read moreRead less
Mechanisms underlying the repellent effects of predator odours in rodents. Rodents show innate fear towards the fur and skin odours of cats. This project seeks to describe the mechanisms behind this phenomenon and determine the potential of cat fur odours as rodent repellents in the field. The project plans to first verify the repellent effects of cat fur on various rat species and house mice in various field locations. It then plans to isolate, identify and synthesise the molecules in cat fur t ....Mechanisms underlying the repellent effects of predator odours in rodents. Rodents show innate fear towards the fur and skin odours of cats. This project seeks to describe the mechanisms behind this phenomenon and determine the potential of cat fur odours as rodent repellents in the field. The project plans to first verify the repellent effects of cat fur on various rat species and house mice in various field locations. It then plans to isolate, identify and synthesise the molecules in cat fur that cause rodent repellent effects and determine their action on rodent pheromone-sensing receptors. Novel cat fur-derived molecules identified in the laboratory will be further tested in the field. Expected project outcomes will be a powerful new rodent repellent with the potential to protect crops and homes, and an understanding of the precise physiological mechanisms whereby feline odours can repel rats and mice which could be used to further develop novel rodent repellents.Read moreRead less
How we remember and misremember traumatic experiences. The project addresses a significant and important problem: the role of memory distortion in Post Traumatic Stress Disorder (PTSD), a global disorder with significant personal, societal and economic costs. The aim of this project is to empirically investigate the extent, causes and triggering conditions of errors in memory for traumatic experiences; particularly exaggeration of these memories, which has been linked to poor psychological adjus ....How we remember and misremember traumatic experiences. The project addresses a significant and important problem: the role of memory distortion in Post Traumatic Stress Disorder (PTSD), a global disorder with significant personal, societal and economic costs. The aim of this project is to empirically investigate the extent, causes and triggering conditions of errors in memory for traumatic experiences; particularly exaggeration of these memories, which has been linked to poor psychological adjustment. Understanding how people exposed to trauma remember, and misremember, aspects of their experiences in ways that influence their recovery is both theoretically and practically important. Indeed, it will help us refine theory and identify possible points of intervention for PTSD sufferers.Read moreRead less
Learning about threats: the neural and behavioural response to predator-related cues in rodents. This project will investigate the anxiety displayed by rats when confronted with the odours of predators such as cats. This anxiety may be very similar to that experienced by humans who suffer from anxiety disorders such as phobias. By investigating the nature of this anxiety, the nature of the stimuli that produce it, and the learning and neural processes that underlie it we may better understand h ....Learning about threats: the neural and behavioural response to predator-related cues in rodents.

By investigating the nature of this anxiety, the nature of the stimuli that produce it, and the learning and neural processes that underlie it we may better understand human anxiety. The project also aims to identify novel chemicals in the fur of cats that have rodent repellent properties. Such chemicals may be of great use in domestic and agricultural contexts where rodents are pests.Read moreRead less
How emotion shapes perception: delineating structural, temporal, and representational properties of emotion-induced blindness. Emotion helps shape conscious perception, with implications for public safety and mental health. This project will reveal mechanisms underlying emotion’s impact on perception. In doing so, it will advance theoretical understanding of basic processes and of how perceptual mechanisms might operate within and inform treatment of emotional disorders.
Assessing the determinants and consequences of safety climate in the maritime industry. This project will examine the predictors and outcomes of safety climate in the Australian maritime industry. Findings from this project will be used to improve safety policies, regulations and practices that aim to minimise the number of accidents and incidents in Australian waters.

Treatment-induced compulsive behaviours: Ethical and policy implications. Compulsive behaviours represent one of the largest preventable burdens in society. Some medications, such as those used to treat Parkinson's disease, can produce severe compulsions in certain individuals, which are akin to addiction. This project will explore: neurocognitive changes caused by these medications; the impact that drug-induced compulsive behaviours have on affected individuals, their sense of agency, identity ....Treatment-induced compulsive behaviours: Ethical and policy implications. Compulsive behaviours represent one of the largest preventable burdens in society. Some medications, such as those used to treat Parkinson's disease, can produce severe compulsions in certain individuals, which are akin to addiction. This project will explore: neurocognitive changes caused by these medications; the impact that drug-induced compulsive behaviours have on affected individuals, their sense of agency, identity and moral responsibility; and the ethical, legal and policy consequences of drug-induced behaviour. This project will help us to understand the neuropsychology of compulsive behaviour and reduce its occurrence. It will also enable society to meet the ethical and policy challenges raised by neuroscience research on compulsive behaviour.Read moreRead less
Impacts of diet on the brain, body, and microbiome. Dietary habits determine cognitive function, metabolism and the composition of the gut microbiome. This project seeks to clarify the role of the gut microbiome in diet-induced changes to cognition. It aims to do so through longitudinal studies of cognitive function in which dietary patterns are systematically varied, and intervention studies where cognition is tested after experimentally manipulating the gut microbiome. Expected outcomes inclu ....Impacts of diet on the brain, body, and microbiome. Dietary habits determine cognitive function, metabolism and the composition of the gut microbiome. This project seeks to clarify the role of the gut microbiome in diet-induced changes to cognition. It aims to do so through longitudinal studies of cognitive function in which dietary patterns are systematically varied, and intervention studies where cognition is tested after experimentally manipulating the gut microbiome. Expected outcomes include new interdisciplinary knowledge spanning psychology, neuroscience, nutrition and metabolism. This project is timely given the enormous shifts in Australian dietary choices. The knowledge to be gained should provide benefits to individual and public health, agriculture, and food systems.Read moreRead less
Sexism in scientific and pseudo-scientific explanations of sex inequality: an empirical, ethical and educative approach. Neuroscientific explanations of sex inequality are scientifically premature, and lead to popular exaggerations that sustain inequality through self-fulfilling effects. This project will increase understanding of these harmful consequences, and bring about essential improvements in both the quality of scientific research, and public understanding.

Unravelling the relationship between food and the brain. This project aims to investigate how highly palatable foods that are high in fat and sugar, interact with the brain to cause their overconsumption. Highly palatable foods cause plasticity in brain reward circuitry in a manner similar to drugs of abuse. Identifying how these "junk" foods interact with reward areas of the brain will explore the neural mechanisms underlying the hedonic nature of appetite. This project will not only inform our ....Unravelling the relationship between food and the brain. This project aims to investigate how highly palatable foods that are high in fat and sugar, interact with the brain to cause their overconsumption. Highly palatable foods cause plasticity in brain reward circuitry in a manner similar to drugs of abuse. Identifying how these "junk" foods interact with reward areas of the brain will explore the neural mechanisms underlying the hedonic nature of appetite. This project will not only inform our understanding of how exposure to these foods can contribute to overeating and obesity, a huge and growing problem in Australia, but will also provide evidence to inform policy options relevant to advertising and marketing of these foods.Read moreRead less
