Decoding change of mind decisions and errors from brain activity in humans. This project intends to provide new insights into how the brain changes a decision to achieve better outcomes. Decision-making is rarely optimal, and in a dynamic world people must often change their initial decisions in order to avoid consequential errors. This project aims to investigate the neural mechanisms underlying such change-of-mind decisions and decision errors in humans. To this end, it plans to use novel deco ....Decoding change of mind decisions and errors from brain activity in humans. This project intends to provide new insights into how the brain changes a decision to achieve better outcomes. Decision-making is rarely optimal, and in a dynamic world people must often change their initial decisions in order to avoid consequential errors. This project aims to investigate the neural mechanisms underlying such change-of-mind decisions and decision errors in humans. To this end, it plans to use novel decoding techniques to predict the evolution of change-of-mind decisions from brain activity while decisions unfold. This approach would clarify how quality of information, effort, and reward are integrated at a neural level to bias people towards changing their decisions. The expected results would provide an improved understanding of the neural dynamics of errors and how the brain corrects decisions online to achieve better outcomes.Read moreRead less
Modelling trajectories of cognitive control in adolescents and young adults. This project aims to develop an innovative framework that models behaviour, brain function and brain structure to characterise developmental trajectories of cognitive control in typically-developing young people, and to test the model’s ability to predict psychosocial outcomes. Cognitive control processes are supported by complex frontal brain networks that develop well into adulthood. Poor cognitive control is linked t ....Modelling trajectories of cognitive control in adolescents and young adults. This project aims to develop an innovative framework that models behaviour, brain function and brain structure to characterise developmental trajectories of cognitive control in typically-developing young people, and to test the model’s ability to predict psychosocial outcomes. Cognitive control processes are supported by complex frontal brain networks that develop well into adulthood. Poor cognitive control is linked to negative psychosocial outcomes (e.g. substance use, high-risk behaviours). This work is expected to inform evidence-based programmes that identify young people at risk and develop targeted training strategies to improve psychosocial outcomes.Read moreRead less

Summary
Decoding unstable decision preferences from brain activity. We often have to make decisions despite lacking clear preferences. This leaves us susceptible to biases from stimuli and information in our environment. This project investigates how simple, perceptual decisions and financial decisions are influenced by contextual information. The project will combine state-of-the-art neuroimaging technology with machine learning methods to develop a novel decision-decoding toolbox that directly predict ....Decoding unstable decision preferences from brain activity. We often have to make decisions despite lacking clear preferences. This leaves us susceptible to biases from stimuli and information in our environment. This project investigates how simple, perceptual decisions and financial decisions are influenced by contextual information. The project will combine state-of-the-art neuroimaging technology with machine learning methods to develop a novel decision-decoding toolbox that directly predicts decision outcomes from brain activity. This will allow investigation of how decision encoding in the brain changes under the influence of contextual information, and will provide the basis for developing an advanced model for human decision-making in real-life situations.Read moreRead less
The brain in real time: a neural model of rhythmic action and perception. This project aims to study a fundamental function of the human brain: its temporal architecture. It will provide an innovative perspective on the neural mechanisms underlying and relating perception, intention, and voluntary action in real time, though a combination of eye-tracking, behaviour, and neural recordings. By providing a common language with which to relate perception, cognition, volition and action, this will ....The brain in real time: a neural model of rhythmic action and perception. This project aims to study a fundamental function of the human brain: its temporal architecture. It will provide an innovative perspective on the neural mechanisms underlying and relating perception, intention, and voluntary action in real time, though a combination of eye-tracking, behaviour, and neural recordings. By providing a common language with which to relate perception, cognition, volition and action, this will provide significant benefits that will transform the way we think about brain function.Read moreRead less
Suicide prevention and management of deliberate self-harm: randomised control trial of an assertive engagement, brief psychotherapy and community linkage model. Suicide is the second commonest cause of death by injury in Australia. Suicide prevention is an important public health priority but rates remain high. People who have previously attempted suicide are most likely to kill themselves.

Suicide is the second commonest cause of death by injury in Australia. Suicide prevention is an important public health priority but rates remain high. People who have previously attempted suicide are most likely to kill themselves. Most suicidal people attend emergency departments where they get inadequate treatment for their psychological and social problems and remain depressed and suicidal. This project will test the effectiveness of a new psychological and social treatment to reduce the depression and link suicidal people with community supports. If successful, this treatment could be provided in any emergency department and help decrease suicide rates in Australia.Read moreRead less
Whether social media literacy mitigates effects of social media in adolescents. This project aims to determine protective and risk factors for problems associated with social media use in early adolescents. In particular, it aims to determine the protective role of social media literacy (the skill to analyse, critique and evaluate social media posts). Although most Australian adolescents use social media, frequent social media engagement and photo-based activities can cause body dissatisfaction, ....Whether social media literacy mitigates effects of social media in adolescents. This project aims to determine protective and risk factors for problems associated with social media use in early adolescents. In particular, it aims to determine the protective role of social media literacy (the skill to analyse, critique and evaluate social media posts). Although most Australian adolescents use social media, frequent social media engagement and photo-based activities can cause body dissatisfaction, disordered eating and compromised well-being. Findings supporting a protective role for social media literacy are expected to inform policy to improve adolescent well-being and pave the way for school-based social media literacy interventions.Read moreRead less
Improving the retention rate for residential treatment of substance abuse by sequential intervention for social anxiety. Alcohol and other drug use is a major social and medical problem, costing the Australian community an estimated $7.6 billion annually. Mental health disorders have been closely linked with increased illicit drug use and physical health problems. Social anxiety (SAD) is highly prevalent amongst individuals presenting with drug and alcohol use disorders. Evidence suggests that ....Improving the retention rate for residential treatment of substance abuse by sequential intervention for social anxiety. Alcohol and other drug use is a major social and medical problem, costing the Australian community an estimated $7.6 billion annually. Mental health disorders have been closely linked with increased illicit drug use and physical health problems. Social anxiety (SAD) is highly prevalent amongst individuals presenting with drug and alcohol use disorders. Evidence suggests that social anxiety symptoms may be responsible for promoting excessive drug use and may be a particularly influential factor in poor treatment retention rates and promoting relapse. Thus, the focus on improving treatment outcomes for individuals with comorbid anxiety and drug use disorders represents an area of considerable importance both nationally and internationally.Read moreRead less
Body image instability, disordered eating and muscle dysmorphia. Body image is a serious public health issue. Dissatisfaction with body shape promotes disordered eating in females who fast and purge to lose weight, and muscle dysmorphia in males who over-exercise and use steroids to gain muscle. We will test the idea that these psychological disorders stem from an unstable body image. Our research will reveal the fundamental risk factors associated with disordered eating and muscle dysmorphia an ....Body image instability, disordered eating and muscle dysmorphia. Body image is a serious public health issue. Dissatisfaction with body shape promotes disordered eating in females who fast and purge to lose weight, and muscle dysmorphia in males who over-exercise and use steroids to gain muscle. We will test the idea that these psychological disorders stem from an unstable body image. Our research will reveal the fundamental risk factors associated with disordered eating and muscle dysmorphia and allow us to identify at-risk individuals on the basis of their body image instability. It will also predict patients' amenability to treatments that target body image, thereby improving outcomes for these individuals.Read moreRead less
Relative efficacy of self-help treatment for insomnia. This project aims to improve available non-pharmacological treatments for insomnia by determining the relative efficacy of various forms of self-help treatment compared to standard, therapist-led, treatment. Sleep disorders have serious consequences and are widespread. Drug therapies are costly and ineffective and, while psychological treatments have a well-established evidence base, they are not utilised by many. Self-help is a potential ....Relative efficacy of self-help treatment for insomnia. This project aims to improve available non-pharmacological treatments for insomnia by determining the relative efficacy of various forms of self-help treatment compared to standard, therapist-led, treatment. Sleep disorders have serious consequences and are widespread. Drug therapies are costly and ineffective and, while psychological treatments have a well-established evidence base, they are not utilised by many. Self-help is a potential solution, but has not been properly evaluated. This project will determine the efficacy of self-help, the best delivery methods, and should result in more individuals with sleep problems receiving better and cheaper help with benefits for them and society in general.Read moreRead less
