Improving the identification of juvenile firesetters at high risk of recidivism. Young firesetters are not only responsible for some fifth of all fires, they also are at risk of becoming adult arsonists. Australian fire services provide educational programs for young firesetters but about a third may continue to light fires. This project will allow clarification of variables most associated with ongoing firesetting behaviour (recidivism), better prediction of high risk juveniles, understanding ....Improving the identification of juvenile firesetters at high risk of recidivism. Young firesetters are not only responsible for some fifth of all fires, they also are at risk of becoming adult arsonists. Australian fire services provide educational programs for young firesetters but about a third may continue to light fires. This project will allow clarification of variables most associated with ongoing firesetting behaviour (recidivism), better prediction of high risk juveniles, understanding of the predictive value of a screening tool, valid assessment of recidivism rates and an increased understanding of mental health agency involvement with firesetter families. These outcomes will help improve programs involving juvenile firesetters, thereby reducing arson and the high cost of uncontrolled fire.Read moreRead less
Brain development during adolescence and the emergence of depression: A longitudinal MRI study. Traditionally mental health services have focused on established disorders. Whilst significant gains in outcomes have been obtained in other areas of health by focusing on early intervention and prevention, in the mental health field this approach has been limited by the inability to predict who is likely to go on to develop serious mental disorder. This study will provide critical information for und ....Brain development during adolescence and the emergence of depression: A longitudinal MRI study. Traditionally mental health services have focused on established disorders. Whilst significant gains in outcomes have been obtained in other areas of health by focusing on early intervention and prevention, in the mental health field this approach has been limited by the inability to predict who is likely to go on to develop serious mental disorder. This study will provide critical information for understanding the risk processes that are operating during the critical phase of early adolescence, and will therefore make a fundamental contribution to our understanding of who, and what, to target in early intervention and prevention strategies.Read moreRead less
Genes, neuroanatomy and family process: Predicting adolescent anxiety and depression. Whilst significant gains in outcomes have been obtained in other areas of health by focusing on early intervention and prevention, in the mental health field this approach has been limited by the paucity of developmentally targeted treatment and prevention strategies. This study will provide unique information regarding the risk processes that are operating during early and late adolescence, and will inform us ....Genes, neuroanatomy and family process: Predicting adolescent anxiety and depression. Whilst significant gains in outcomes have been obtained in other areas of health by focusing on early intervention and prevention, in the mental health field this approach has been limited by the paucity of developmentally targeted treatment and prevention strategies. This study will provide unique information regarding the risk processes that are operating during early and late adolescence, and will inform us about how the family environment can act to modulate the impacts of biological vulnerability on risk for mental disorder. This project will contribute to our understanding of who, and what, to target in early intervention and prevention strategies.Read moreRead less
The cognitive neuroscience of executive control: behavioural, physiological and genetic mechanisms. How genes influence our human abilities to think, reason and control behaviour has puzzled scientists for decades. The human genome project has allowed us to ask how individual genes influence these capacities. Understanding the genetics of these abilities provides a solid platform from which to launch gene discovery projects in clinical disorders where these abilities are compromised. The curr ....The cognitive neuroscience of executive control: behavioural, physiological and genetic mechanisms. How genes influence our human abilities to think, reason and control behaviour has puzzled scientists for decades. The human genome project has allowed us to ask how individual genes influence these capacities. Understanding the genetics of these abilities provides a solid platform from which to launch gene discovery projects in clinical disorders where these abilities are compromised. The current project is directly relevant to the genetics of mental disorders, such as attention deficit hyperactivity (ADHD), that place a large burden, both financially and emotionally, on our society. Understanding the genes and biological pathways that increase risk for mental disorders will ultimately lead to improved treatments for these conditions.Read moreRead less
The etiology of social anxiety and its impact on development across the lifespan. Social anxiety is a distressing early-onset disorder often associated with other psychiatric conditions in later life. This study will extend our previous work that has identified factors associated with its onset. We propose that these factors and the social anxiety itself may disrupt psychosocial development, at the time of onset, and throughout the lifespan. We aim to investigate these innovative hypotheses thro ....The etiology of social anxiety and its impact on development across the lifespan. Social anxiety is a distressing early-onset disorder often associated with other psychiatric conditions in later life. This study will extend our previous work that has identified factors associated with its onset. We propose that these factors and the social anxiety itself may disrupt psychosocial development, at the time of onset, and throughout the lifespan. We aim to investigate these innovative hypotheses through a sequence of three studies, with adults, children and adolescents. The results will inform prevention and early intervention regimes, thereby reducing both the incidence of social anxiety and the burden of the disorder.Read moreRead less
Investigating the social brain: The neural basis of the link between depressed mood and social cognition. Mood and social relationships are amongst the most important determinants of well being, life functioning, and both mental and physical health. To understand how mood and social behaviour interact, this project will examine the brain mechanisms that are responsible for the impact of mood states on processing social threat stimuli (e.g., stimuli suggesting humiliation, rejection or defeat). T ....Investigating the social brain: The neural basis of the link between depressed mood and social cognition. Mood and social relationships are amongst the most important determinants of well being, life functioning, and both mental and physical health. To understand how mood and social behaviour interact, this project will examine the brain mechanisms that are responsible for the impact of mood states on processing social threat stimuli (e.g., stimuli suggesting humiliation, rejection or defeat). This work will have important implications for understanding vulnerability to recurrent depression, where these processes have been implicated in previous research. The high prevalence of these disorders, and the high cost that they represent to society, makes basic research of this type vital at this time.Read moreRead less

This research contributes to promoting and maintaining good health. The burden of bulimic eating disorders in the community is high, frequently ignored and increasing. Our research will pave the way for improved understanding of eating disorders and a reduction of stigma in relation to these problems. In so doing, it will lead to reduced shame and suffering for people with eating disorders and enhance appropriate treatment seeking and the quality of advice received from family, friends and health professionals. A public health intervention based on our findings will contribute to a more tolerant and understanding community.Read moreRead less
Studying the effects of repetitive transcranial magnetic stimulation with near Infrared spectroscopy. Repetitive transcranial magnetic stimulation (rTMS) is increasingly being used as a tool in studying human and animal brain function and in the treatment of brain disorders but there are fundamental gaps in our understanding of its basic mechanisms of action and hence our capacity to optimise protocols. This research will use near infrared spectroscopy to study the range of potential ways of alt ....Studying the effects of repetitive transcranial magnetic stimulation with near Infrared spectroscopy. Repetitive transcranial magnetic stimulation (rTMS) is increasingly being used as a tool in studying human and animal brain function and in the treatment of brain disorders but there are fundamental gaps in our understanding of its basic mechanisms of action and hence our capacity to optimise protocols. This research will use near infrared spectroscopy to study the range of potential ways of altering brain activity with rTMS. It will substantially enhance the applicability of the technique ultimately improving our knowledge of human and animal brain function and outcomes for patients with depression and other disorders. It will help reinforce Australia as a leading country in the development of brain stimulation techniques.Read moreRead less
Evaluation of a Training Program for Staff to Recognize Depression Among Aged People Living in Residential and Community Care. Depression is a significant problem among older people, and is likely to increase in prevalence with the aging of the population. A large percentage of depressed older people fail to receive treatment because their depression is not diagnosed. This illness leads to high economic and social costs if it is not diagnosed and treated. This project will evaluate the effective ....Evaluation of a Training Program for Staff to Recognize Depression Among Aged People Living in Residential and Community Care. Depression is a significant problem among older people, and is likely to increase in prevalence with the aging of the population. A large percentage of depressed older people fail to receive treatment because their depression is not diagnosed. This illness leads to high economic and social costs if it is not diagnosed and treated. This project will evaluate the effectiveness of a training program to assist carers to detect depression, and so refer older people for treatment of this condition. Read moreRead less
Sleep and circadian influences on mood and Autonomic Nervous System control of the heart. Most biological and behavioural processes have a 24-hour oscillation in activity. A critical question is whether this oscillation is a consequence of the sleep-wake cycle or the circadian system (our internal biological clock). This project will investigate circadian influence over two biological systems that have important influences over behaviour, the Autonomic Nervous System (ANS) and the Behavioural Fa ....Sleep and circadian influences on mood and Autonomic Nervous System control of the heart. Most biological and behavioural processes have a 24-hour oscillation in activity. A critical question is whether this oscillation is a consequence of the sleep-wake cycle or the circadian system (our internal biological clock). This project will investigate circadian influence over two biological systems that have important influences over behaviour, the Autonomic Nervous System (ANS) and the Behavioural Facilitation System (BFS). Specifically, we will investigate the relationship between circadian control of the heart and the induction and quality of sleep, and the circadian influence on aspects of personality (neuroticism) and mood (Positive Affect) that are related to the BFS.Read moreRead less
