Understanding biological pathways underlying social behaviour in humans. This project aims to show for the first time how oxytocin interacts with neural social and reward pathways to guide social behaviour. Oxytocin is a natural neuropeptide and hormone that has a critical role in the regulation of social behaviour across mammalian species. In animals, direct evidence demonstrates how endogenous and exogenous oxytocin interacts with social and reward neural pathways to alter social behaviour, in ....Understanding biological pathways underlying social behaviour in humans. This project aims to show for the first time how oxytocin interacts with neural social and reward pathways to guide social behaviour. Oxytocin is a natural neuropeptide and hormone that has a critical role in the regulation of social behaviour across mammalian species. In animals, direct evidence demonstrates how endogenous and exogenous oxytocin interacts with social and reward neural pathways to alter social behaviour, including social recognition, relationship formation, and long-term bonds. The project intends to use radio-labelling techniques in combination with positron emission tomography to track oxytocin and show what regions of the brain oxytocin impacts to then influence social cognition and behaviour in humans.Read moreRead less
Neural mechanisms for human form perception. This project aims to determine if there is a single cortical mechanism underlying the human ability to discriminate and recognise objects. It has been speculated that different classes of objects, or forms require different processes. Demonstrating a single process would be a significant advance towards understanding the neural mechanisms giving rise to our ability to segment visual fields into meaningful objects and background. This research provides ....Neural mechanisms for human form perception. This project aims to determine if there is a single cortical mechanism underlying the human ability to discriminate and recognise objects. It has been speculated that different classes of objects, or forms require different processes. Demonstrating a single process would be a significant advance towards understanding the neural mechanisms giving rise to our ability to segment visual fields into meaningful objects and background. This research provides a means for testing models of the neural interactions thought to be generating human form perception and will help us discover how the visual cortex converts raw sensory input into object and form perception.Read moreRead less

This project aims to investigate the neurobiological and neuropsychological determinants of habit formation and change in the context of ageing, by combining cutting-edge techniques in psychology, behavioural neuroscience and neuroimaging. This research expects to generate new knowledge in the area of automatic habits and behaviour change, by investigating how these processes are affected in ageing using an interdisciplinary approach. Expected outcomes include a new, comprehensive model of habit formation and change in ageing. This should provide significant benefits, as it will lay the foundation for future habit-based behaviour change interventions to support older people to age well and productively.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

For the first time scientists are beginning to reveal the complex relationship between human brain function and behaviour. These advances have stemmed almost exclusively from the development of sophisticated brain scanning techniques that provide high-resolution images of physiological changes associated with perceptual, cognitive and motor behaviours. This application seeks support for a state-of-the-art scanner to obtain high-resolution images of the brain as healthy adults perceive, think, learn, remember and decide. The facility will enable Australian scientists to understand the complex links between brain and behaviour in health and disease.Read moreRead less

Understanding how the brain combines sensory information. The ease with which we perceive the external world belies the complexity involved in integrating different sensory inputs. How does the brain achieve this fundamental operation?

The ease with which we perceive the external world belies the complexity involved in integrating different sensory inputs. How does the brain achieve this fundamental operation? The project will address this question using a multidisciplinary approach that combines computational modelling, brain imaging, and psychophysical techniques. The expected outcomes of the project are a better understanding of how people perceive the world through optimal integration of sensory cues. In addition to advancing basic scientific knowledge, the findings will illuminate perceptual anomalies in normally developing children and will provide a foundation for reducing a debilitating side effect of virtual reality systems known as ‘cybersickness’.Read moreRead less
Western-style diet and impairments in food-intake control in humans. Animals fed a Western-style (W-S) diet high in saturated fat and added sugar rapidly develop cognitive impairments, which include disrupted food-intake control. This project aims to see if this also occurs in lean healthy people who eat a W-S diet. That is, are W-S diets associated with impaired cognition, and especially food-intake control, in adults and children, and is this caused by a W-S diet?

Animals fed a Western-style (W-S) diet high in saturated fat and added sugar rapidly develop cognitive impairments, which include disrupted food-intake control. This project aims to see if this also occurs in lean healthy people who eat a W-S diet. That is, are W-S diets associated with impaired cognition, and especially food-intake control, in adults and children, and is this caused by a W-S diet? Obesity is a major public health issue and the significance of this project lies in testing a new account of how overeating may first occur. The expected outcome aims to show that a W-S diet can disrupt various aspects of cognition in adults and children, including food-intake control, providing an entirely new basis to argue for a better diet.Read moreRead less

Research demonstrates that structured writing about past upsetting experiences is beneficial for physical and psychological health. The aim of this study is to identify the process of change responsible for these benefits. Three processes, based on trauma theory, have been identified (exposure, devaluation, and benefit-finding) and are manipulated within the writing paradigm. This study will test these processes in predicting future health benefits. It will increase the effectiveness of the writing paradigm for the general population, provide manualised variations of the writing paradigm based on trauma theory, examine patient-matching variables, and provide a base to conduct research in clinical populations.Read moreRead less

Stigmatisation is characterised by chronic avoidance of a person(s) by other people. Infectious disease may produce an apparently similar form of isolation—disease avoidance.

The aim of this project is to test a disease avoidance model of stigmatisation. Stigmatisation is characterised by chronic avoidance of a person(s) by other people. Infectious disease may produce an apparently similar form of isolation—disease avoidance. This project proposes that many forms of stigmatisation reflect the activation of this disease avoidance system, which is predisposed to respond to signs of disease, irrespective of their accuracy. This will represent a significant shift in thinking about this issue and aims to provide the first empirically based model of stigmatisation as an evolved disposition that causes the exclusion of people who look like they may carry an infectious disease - even if they do not.Read moreRead less
