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
A model of sex offender registration, monitoring, and risk management. This research will investigate the ways in which sexual offenders are managed in the community and identify the most effective means of preventing further offending, thereby promoting community safety.
Improving the diagnosticity of eyewitness memory choices. Eyewitness identification error is common and costly. This project aims to improve the quality of information provided by eyewitnesses, and the ability of police officers and triers of fact (e.g., juries, judges) to evaluate this information. Laboratory investigations will determine how best to test memory and confidence to achieve this aim. A new class of cognitive models will provide a unified account of response accuracy, response time ....Improving the diagnosticity of eyewitness memory choices. Eyewitness identification error is common and costly. This project aims to improve the quality of information provided by eyewitnesses, and the ability of police officers and triers of fact (e.g., juries, judges) to evaluate this information. Laboratory investigations will determine how best to test memory and confidence to achieve this aim. A new class of cognitive models will provide a unified account of response accuracy, response time, and confidence, suitable for application to computerized testing scenarios. The models and testing methods validated in the laboratory will be refined for application in eyewitness memory settings, facilitating better evaluation of identification evidence, and potentially reducing wrongful convictions.Read moreRead less
Killing which averts suffering: the role of norms and empathy. Abattoir workers and butchers kill animals to prepare food, farmers to cull stock, and veterinarians to alleviate suffering. Soldiers kill other humans in war, police or security guards to protect the public, and doctors to enact legal euthanasia. Research shows that these tasks can be confronting, and even traumatic. This project aims to test the processes through which people learn socially supported palliative killing to avert suf ....Killing which averts suffering: the role of norms and empathy. Abattoir workers and butchers kill animals to prepare food, farmers to cull stock, and veterinarians to alleviate suffering. Soldiers kill other humans in war, police or security guards to protect the public, and doctors to enact legal euthanasia. Research shows that these tasks can be confronting, and even traumatic. This project aims to test the processes through which people learn socially supported palliative killing to avert suffering and their neural underpinnings, with a focus on norms and empathic distress. It will focus on two core samples: veterinarians, who must euthanize animals, and health practitioners in Victoria, where legal changes will introduce ‘voluntary assisted dying’ in mid-2019. It will investigate how practitioners learn palliative killing, and what the impact is on psychological variables such as empathy and identity. It will generate new understandings of social influence around life and death decisions, provide an evidence basis to inform policy makers, and help institutions and practitioners seeking to manage distress and respond to fast-moving, controversial policy changes.Read moreRead less
How inhibition shapes human brain oscillations and working memory capacity. This project aims to investigate the link between inhibitory mechanisms, gamma oscillations and working memory in humans. Retaining information in short-term ‘working’ memory is crucial for cognition, influencing our personality and intelligence. However, the brain mechanisms underlying this process are unclear. Evidence from animal/computational research indicates that brain oscillations in high frequency ‘gamma’ bands, ....How inhibition shapes human brain oscillations and working memory capacity. This project aims to investigate the link between inhibitory mechanisms, gamma oscillations and working memory in humans. Retaining information in short-term ‘working’ memory is crucial for cognition, influencing our personality and intelligence. However, the brain mechanisms underlying this process are unclear. Evidence from animal/computational research indicates that brain oscillations in high frequency ‘gamma’ bands, which depend on neural inhibition, are critical for working memory. Mapping a path from molecules to cognition will detail how neural mechanisms shape human behavioural performance and guide efforts to enhance memory and cognitive function.Read moreRead less
Functional impact of high fat and high sugar diets on memory encoding. This project aims to determine the functional mechanisms of how fats and sugar affect neuronal processes vital for learning and memory. Expected outcomes will define the neural mechanisms underpinning cognitive changes in emotional and spatial memory encoding, and how these relate to brain and metabolic parameters. This will provide benefits by unveiling the possible consequences of dietary fat and sugar on the brain, and th ....Functional impact of high fat and high sugar diets on memory encoding.

Common synaptic inputs to human upper airway muscles. Changes in the activity of upper airway muscles at sleep onset contribute to the development of Obstructive Sleep Apnoea. The aim of this project is to investigate how the brain controls upper airway muscles during wakefulness and sleep and to identify the pathological processes that lead to the development of Obstructive Sleep Apnoea.
Left of centre: Attentional distortions in the mental representation of space in healthy and clinical populations. Stroke patients cost the Australian economy $1.3bn pa in addition to their social burden, but effective diagnosis and rehabilitation is impeded by a lack of fundamental research into the cognitive and neural mechanisms that underlie attentional disorders. Our research will provide significant new insights into how the brain deploys attention in external and imagined space and will l ....Left of centre: Attentional distortions in the mental representation of space in healthy and clinical populations. Stroke patients cost the Australian economy $1.3bn pa in addition to their social burden, but effective diagnosis and rehabilitation is impeded by a lack of fundamental research into the cognitive and neural mechanisms that underlie attentional disorders. Our research will provide significant new insights into how the brain deploys attention in external and imagined space and will lead to more effective management and treatment of stroke victims. Our new test of attentional disorders is independent of a patient's inability to see or move and will enable more effective diagnosis. Our research provides the fundamental knowledge base for our discipline and is vital for developing the next generation of Australia's cognitive neuroscientists. Read moreRead less
Left to right is front to back: attentional distortions in near and far space for healthy and clinical populations. We are investigating a perceptual bias that makes people think objects right in front of them are actually slightly to the right but objects far away are slightly to the left. This project will help understand why this happens, to help reduce traffic collisions and help people with brain damage that causes similar perceptual biases.
Attentional asymmetries for navigation in healthy and clinical groups. This project plans to investigate how differences in attentional capacity between the left and right sides of the brain affect the ability to walk or manoeuvre vehicles between obstacles. To navigate our environment and avoid obstacles, we need to attend to stimuli that are important and ignore those that are not. Unfortunately, the brain’s attentional capacity is limited, which can result in errors and collisions. Using the ....Attentional asymmetries for navigation in healthy and clinical groups. This project plans to investigate how differences in attentional capacity between the left and right sides of the brain affect the ability to walk or manoeuvre vehicles between obstacles. To navigate our environment and avoid obstacles, we need to attend to stimuli that are important and ignore those that are not. Unfortunately, the brain’s attentional capacity is limited, which can result in errors and collisions. Using the techniques of cognitive neuroscience, the project aims to provide a better understanding of the cognitive and neural mechanisms that govern attention in an applied setting. It expects to identify the factors that exacerbate lapses in attention and collisions. The effect of everyday impediments such as mobile phones, alcohol and fatigue will be investigated together with means of minimising these attentional lapses and improving safety.Read moreRead less
