Investigating memory reliability in intoxicated witnesses of crime. Eyewitness testimony is a crucial piece of evidence for solving a crime. Inaccurate testimony leads to miscarriages of justice such as failed prosecutions or false convictions. Many witnesses and victims are affected by alcohol or other drugs during the crime. This project brings together a multidisciplinary team aiming to improve understanding of how intoxication with different substances affects the reliability of victim and w ....Investigating memory reliability in intoxicated witnesses of crime. Eyewitness testimony is a crucial piece of evidence for solving a crime. Inaccurate testimony leads to miscarriages of justice such as failed prosecutions or false convictions. Many witnesses and victims are affected by alcohol or other drugs during the crime. This project brings together a multidisciplinary team aiming to improve understanding of how intoxication with different substances affects the reliability of victim and witness memory accuracy. Crucially, crimes are frequently distressing; therefore the interaction between intoxication and stress urgently requires exploration. This project will significantly advance our understanding of key mechanisms behind drug effects on memory, and support fairer judicial outcomes for all. Read moreRead less

Summary
Measuring the sound of inner speech with advanced brain signal analyses. The overarching aim of this project is to develop an objective, electrophysiological marker capable of identifying the auditory properties of a person’s inner speech, which is defined as the silent production of words in one’s mind. This will be accomplished by combining novel experimental paradigms with advanced brain signal analyses. This marker would represent a historically significant event, placing Australia at the fo ....Measuring the sound of inner speech with advanced brain signal analyses. The overarching aim of this project is to develop an objective, electrophysiological marker capable of identifying the auditory properties of a person’s inner speech, which is defined as the silent production of words in one’s mind. This will be accomplished by combining novel experimental paradigms with advanced brain signal analyses. This marker would represent a historically significant event, placing Australia at the forefront of cognitive science. It would provide deep insight into the fundamental nature of inner speech, such as whether it is a “special form” of overt speech, and would inform the ongoing development of brain-computer interfaces aimed at deciphering inner speech for people who are unable to produce overt speech.Read moreRead less
Integrating holistic processing and face-space approaches to the perception of facial identity. Recognising faces is a socially crucial task, and humans are remarkably good at it. Scientists investigating the 'software' our brains use to recognise faces have referred to two different theories -- one when explaining why we distinguish faces better than objects, and the other in explaining why we distinguish some people's faces more easily than others. The project aims to integrate these two theor ....Integrating holistic processing and face-space approaches to the perception of facial identity. Recognising faces is a socially crucial task, and humans are remarkably good at it. Scientists investigating the 'software' our brains use to recognise faces have referred to two different theories -- one when explaining why we distinguish faces better than objects, and the other in explaining why we distinguish some people's faces more easily than others. The project aims to integrate these two theories. This has two potential long-term benefits: it will give a stronger basis for understanding what goes wrong in people where face recognition does not develop normally; and, the improved knowledge from a biological system may also lead to improved computer face recognition algorithms (eg. for airport security).Read moreRead less
Testing theoretical models of age and disease related changes to inform prevention. Pathological brain changes associated with future cognitive decline become detectable in the 40s or earlier. Yet little is known about what constitutes normal brain ageing in mid-life. Using a number of neuroimaging and epidemiological techniques this project will scrutinise brain and cognitive ageing in middle-age and their significance.
Future Keepers: impacts of climate change on ecosystem function providers. The aim of this project is to predict how key ecosystem service providers may change under resource limitation and thermal stress. The project seeks to assess how common species respond to climatic fluctuations and resource limitations when competing for resources in familiar and novel environments along six biogeographic transects throughout Australia. In combination with hypothesis-driven field, laboratory and transplan ....Future Keepers: impacts of climate change on ecosystem function providers. The aim of this project is to predict how key ecosystem service providers may change under resource limitation and thermal stress. The project seeks to assess how common species respond to climatic fluctuations and resource limitations when competing for resources in familiar and novel environments along six biogeographic transects throughout Australia. In combination with hypothesis-driven field, laboratory and transplant experiments, citizen science will be used to create a longitudinal data set of the constraints put on dominant and functionally important species. The project also seeks to enable more robust forecasting of biological responses to environmental change by integrating both empirical and theoretical capabilities.Read moreRead less
Variation in the arginine vasopressin 1a receptor (AVPR1a) gene, the social environment, general health and wellbeing. The project aims to investigate how the arginine vasopressin 1a gene affects gene expression and influences social behaviour and ultimately health and wellbeing. This research will contribute to understanding the importance of individual differences in social policy and interventions aimed at improving health and wellbeing.
Temperature-dependent toxicity of plant secondary compounds to mammalian herbivores. Changes in the toxicity of plant secondary compounds is an unexplored consequence of rises in ambient temperatures. Evidence from agricultural and laboratory studies suggests that temperature dependent toxicity can have major effects on the intake and metabolism of plant secondary metabolites by mammals. These effects are mediated by a decrease in liver metabolism and by the effects of plant secondary metabolite ....Temperature-dependent toxicity of plant secondary compounds to mammalian herbivores. Changes in the toxicity of plant secondary compounds is an unexplored consequence of rises in ambient temperatures. Evidence from agricultural and laboratory studies suggests that temperature dependent toxicity can have major effects on the intake and metabolism of plant secondary metabolites by mammals. These effects are mediated by a decrease in liver metabolism and by the effects of plant secondary metabolites on mitochondrial function which leads to greater heat production. The project will quantify the importance of temperature dependent toxicity and measures the changes in the cost of detoxification to better model the effects of climate change on marsupial herbivores.Read moreRead less
Sensory integration in the whisker pathway: cortical transformations and the neuronal mechanisms that underlie decision confidence. How does the brain use information collected by sensory systems to make decisions? This study combines behavioural experiments with neuronal recording from various brain regions to understand the neuronal mechanisms that integrate sensory signals to generate representations and guide the appropriate behavioural action.
Perceptual and psychosocial factors associated with individual differences in face identity and face expression processing. What makes one person better or worse than another at recognising faces, or the emotions displayed in those faces? This project examines which aspects of visual perception contribute to these abilities, and their associations with problems such as debilitating social anxiety and young children's anti-social behaviour.

This project will enable Australia to remain at the forefront of research in the cognitive neurosciences, as well as provide training opportunities to Australian doctoral students and postdoctoral fellows in the use of MEG in research. Finally, the MEG laboratory will allow Australian researchers to fill important gaps in our understanding of several areas of cognitive neuroscience, including basic auditory and visual processing, the study of cognitive processing in schizophrenia and in children with dyslexia and/or specific language impairment.Read moreRead less
