This project aims to investigate one of society’s most invisible ‘frontline’ trauma workforces—the online content moderators responsible for limiting the public’s exposure to distressing and sensitive content on social media. Using a series of rigorous experiments, and cutting-edge psychological and physiological assessment techniques, the research will advance our understanding of the impact of indirect trauma on mental health. Expected outcomes include novel empirical evidence for preventative strategies that will predict, monitor and reduce negative mental health outcomes. This will provide significant global benefits to people with indirect trauma experiences, such as defence and forensic personnel.Read moreRead less

Child victims: Providing protection from re-victimisation and offending. This project aims to improve understanding of the impact of child abuse, neglect and exposure to domestic violence on young people’s future experiences of re-victimisation and offending. It expects to generate new evidence about the maltreatment experiences that increase risk of youth re-victimisation and offending, potential causal mechanisms and factors that might aggravate or buffer children from these harmful effects. E ....Child victims: Providing protection from re-victimisation and offending. This project aims to improve understanding of the impact of child abuse, neglect and exposure to domestic violence on young people’s future experiences of re-victimisation and offending. It expects to generate new evidence about the maltreatment experiences that increase risk of youth re-victimisation and offending, potential causal mechanisms and factors that might aggravate or buffer children from these harmful effects. Expected outcomes include increased knowledge to inform effective policy and interventions aimed at identifying at-risk children and meeting young people’s needs related to adverse legal outcomes. This should help improve public safety, reduce the economic impact of maltreatment and support vulnerable children to thrive.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
Investigating the role of Zona Incerta RXFP3+ cells in learning and memory. Learning and memory are fundamental to human and animal behaviour. We identified a specific population of cells in the zona incerta of the brain, where activation inhibits expression of memory, and facilitates the acquisition of new learning. Aside from our observations, nothing is currently known about the anatomy and function of these cells. This project aims to map how they connect to the rest of the brain, to observe ....Investigating the role of Zona Incerta RXFP3+ cells in learning and memory. Learning and memory are fundamental to human and animal behaviour. We identified a specific population of cells in the zona incerta of the brain, where activation inhibits expression of memory, and facilitates the acquisition of new learning. Aside from our observations, nothing is currently known about the anatomy and function of these cells. This project aims to map how they connect to the rest of the brain, to observe how these connections are recruited during learning and memory, and then to test their function experimentally. The outcomes will extend the known neural circuitry that controls learning by defining how and where these unexplored pathways fit within it; thus advancing knowledge regarding neural regulation of behaviour.

Hunger flexibly modifies hypothalamic neural circuits responding to threat. Animal and human behaviour frequently involves a choice between actions or goals with conflicting positive and negative outcomes. However, the appropriate action or goal in conflicting situations often depends on physiological pressures like hunger, stress and mating opportunities. For example, the need for resources within an environment, such as food, drives approach behaviour, whereas threats to survival, such as pred ....Hunger flexibly modifies hypothalamic neural circuits responding to threat. Animal and human behaviour frequently involves a choice between actions or goals with conflicting positive and negative outcomes. However, the appropriate action or goal in conflicting situations often depends on physiological pressures like hunger, stress and mating opportunities. For example, the need for resources within an environment, such as food, drives approach behaviour, whereas threats to survival, such as predator cues, enhance avoidance behaviour. This project will uncover the neural circuitry and endocrine mechanisms through which hunger influences hypothalamic threat-detecting circuits that suppress food intake. These studies provide a new hypothalamic model to understand risk/reward decision in the brain.Read moreRead less
Informing intervention responses to violent offenders through data linkage. The project aims to capitalise on new data access capacity to improve knowledge on violent offender pathways and criminogenic needs, such as acquired brain injury, to reduce offending and re-offending. Violence is a major social and health issue nationally and internationally. While there has been substantial investment in treatment/prevention campaigns, rates of violence remain high.

The project aims to capitalise on new data access capacity to improve knowledge on violent offender pathways and criminogenic needs, such as acquired brain injury, to reduce offending and re-offending. Violence is a major social and health issue nationally and internationally. While there has been substantial investment in treatment/prevention campaigns, rates of violence remain high. Using diverse linked administrative data, we will identify key risk factors and times in trajectories, as well as effective treatment/justice responses. Expected benefits include evidence-based recommendations and engagement with policymakers targeting recidivism, offender screening, treatment, and coordinated violence prevention policy and practice.Read moreRead less

The ups and downs of visuospatial attention. The brain has a remarkable capacity to provide a coherent experience of the world by seamlessly integrating sights and sounds from different locations. It is only after brain damage, or when faced with a high attentional load, that our limitations become apparent. The project aims to investigate these limitations by determining how spatial location influences attention in relation to distractibility, cross-modal input and emotionality.

The brain has a remarkable capacity to provide a coherent experience of the world by seamlessly integrating sights and sounds from different locations. It is only after brain damage, or when faced with a high attentional load, that our limitations become apparent. The project aims to investigate these limitations by determining how spatial location influences attention in relation to distractibility, cross-modal input and emotionality. Eye tracking and physiological measures of arousal will be combined with traditional cognitive measures to provide a deeper understanding of spatial attention. This project aims to improve attentional models and develop innovative strategies to increase safety by decreasing inattention and distraction.Read moreRead less
The impact of female sex hormones on neurodevelopment. This project aims to characterise the contribution of sex hormones to the development of emotional brain circuits in female adolescents. Puberty is associated with profound changes in emotional behaviours in females, but we know little about the underlying brain mechanisms. In particular, research has neglected to consider the role of the sex hormones for which changes are a defining feature of female puberty (eg, oestradiol). This work will ....The impact of female sex hormones on neurodevelopment. This project aims to characterise the contribution of sex hormones to the development of emotional brain circuits in female adolescents. Puberty is associated with profound changes in emotional behaviours in females, but we know little about the underlying brain mechanisms. In particular, research has neglected to consider the role of the sex hormones for which changes are a defining feature of female puberty (eg, oestradiol). This work will be the first to comprehensively advance our understanding of the unique role of sex hormones in shaping the adolescent female brain. It will provide critical understanding of how individual differences in hormonal factors increase risk for emotional problems in females, and inform treatment strategies.Read moreRead less

Using cutting-edge technology to manipulate and record neural activity this project will elucidate the brain circuits that integrate threat and appetite to minimize stress exposure during foraging. This will expand our knowledge on how the brain perceives and responds to hunger and may provide relevant information for a large number of basic biological processes controlling the brain. Expected outcomes of this project will contribute to a better understanding of the circuitry controlling more complex decisions from food selection through to social interactions. This should provide significant benefits for Australia’s competitiveness within neuroscience research.Read moreRead less
