Social psychological, personality, and neural processes underlying anger, aggression, and health. The Australian Institute of Criminology estimates the cost of assault, sexual assault, and homicide in Australia at over $2.5 billion per annum. Despite these enormous costs, very little is known about the cognitive and neural mechanisms guiding these phenomena. This research will also provide cues regarding risk for domestic violence.

The Australian Institute of Criminology estimates the cost of assault, sexual assault, and homicide in Australia at over $2.5 billion per annum. Despite these enormous costs, very little is known about the cognitive and neural mechanisms guiding these phenomena. This research will also provide cues regarding risk for domestic violence. Understanding domestic violence is especially significant because it is the leading cause of homicide among women in Australia. The insights gained from this research may lead to substantial social (e.g., stronger social fabric, reduced crime) and economic benefit (e.g., reduced spending on healthcare and crime).Read moreRead less
Are there common mechanisms for the inhibition of fear? Disorders of fear and anxiety affect up to 28% of Australians across their lives. This project studies how the brain inhibits fear and anxiety. It has four National Benefits. First, the knowledge generated by this project will contribute to coherent theoretical accounts of fear inhibition. Second, it will increase Australia's competitiveness and reputation in experimental psychology and behavioural neuroscience. Third, it will provide novel ....Are there common mechanisms for the inhibition of fear? Disorders of fear and anxiety affect up to 28% of Australians across their lives. This project studies how the brain inhibits fear and anxiety. It has four National Benefits. First, the knowledge generated by this project will contribute to coherent theoretical accounts of fear inhibition. Second, it will increase Australia's competitiveness and reputation in experimental psychology and behavioural neuroscience. Third, it will provide novel insights into ways of reducing anxiety and fear among sufferers of clinical anxiety disorders. Finally, it will provide internationally competitive training opportunities for Australian students.

The regulation of fear and attention: From genes to the brain to behaviour. Exposure to dangerous events elicits fear concomitant with attentional processing of environmental stimuli accompanying those events. However this fear and attention are typically inhibited so that they are restricted to dangerous events or stimuli which signal them. This project studies the role of endogenous opioids in the inhibition of fear and threat-related attention. It studies opioid inhibition in terms of its con ....The regulation of fear and attention: From genes to the brain to behaviour. Exposure to dangerous events elicits fear concomitant with attentional processing of environmental stimuli accompanying those events. However this fear and attention are typically inhibited so that they are restricted to dangerous events or stimuli which signal them. This project studies the role of endogenous opioids in the inhibition of fear and threat-related attention. It studies opioid inhibition in terms of its consequences for gene transcription, learning, and attention. It will provide the first integrated analysis of fear inhibition, from the level of the gene to the brain to behaviour. Thus, the project will provide significant insights into the biological complexity underpinning vulnerability to anxiety and fear.Read moreRead less
Predicting danger: The nature, consequences, and neural mechanisms of predictive fear learning. This project has four major national benefits. First, it addresses a fundamental scientific issue from a novel perspective to increase knowledge. By combining innovative approaches to study how the brain predicts danger, it will shed light on the relationship between brain and behaviour. Second, the project will contribute significantly to Australia's international competitiveness and reputation in ex ....Predicting danger: The nature, consequences, and neural mechanisms of predictive fear learning. This project has four major national benefits. First, it addresses a fundamental scientific issue from a novel perspective to increase knowledge. By combining innovative approaches to study how the brain predicts danger, it will shed light on the relationship between brain and behaviour. Second, the project will contribute significantly to Australia's international competitiveness and reputation in experimental psychology. Third, the knowledge generated by this project has the potential to improve the welfare of Australians by addressing an increasingly important health problem - anxiety. Finally, the project provides outstanding, internationally competitive, training opportunities for Australian students in Psychology.Read moreRead less
Neural mechanisms of attention in the honeybee and Drosophila melanogaster. By examining convergent neural mechanisms of attention in insects and comparing these mechanisms to those found in vertebrates, we may uncover basic principles of how attention operates in widely divergent systems. This type of basic scientific research could be used to provide a framework to develop better approaches for treatment for individuals with defects in attention. Such defects are symptoms of several psycholo ....Neural mechanisms of attention in the honeybee and Drosophila melanogaster. By examining convergent neural mechanisms of attention in insects and comparing these mechanisms to those found in vertebrates, we may uncover basic principles of how attention operates in widely divergent systems. This type of basic scientific research could be used to provide a framework to develop better approaches for treatment for individuals with defects in attention. Such defects are symptoms of several psychological conditions, including attention deficit disorder, autism, and schizophrenia, which have major social and economic costs in Australia. Therefore, by expanding our understanding of how attention operates at the level of neurons, we can begin to develop targeted treatments for addressing these conditions. Read moreRead less
Cerebral plasticity or early vulnerability? Identifying critical periods for childhood development and recovery. The primary aim of the study is to identify critical time periods during brain development when an insult will have more deleterious consequences for recovery and outcome. The study will also examine the impact of other potential influences to recovery following early brain disease, and determine whether their impact varies across development. Finally, the study will investigate wh ....Cerebral plasticity or early vulnerability? Identifying critical periods for childhood development and recovery. The primary aim of the study is to identify critical time periods during brain development when an insult will have more deleterious consequences for recovery and outcome. The study will also examine the impact of other potential influences to recovery following early brain disease, and determine whether their impact varies across development. Finally, the study will investigate whether specific cognitive and behavioural domains are differentially effected, depending on their maturity at the time of brain insult. Findings from this study will inform the development of conceptual models of early brain insult and recovery of function, and contribute to clinical practice.Read moreRead less
