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

This project aims to understand the neural mechanisms of working memory, a fundamental cognitive function in humans, using a novel framework which combines non-invasive brain stimulation, neuroimaging, pharmacological and experimental manipulations, and biological modelling. Expected outcomes include a critical understanding of the cellular mechanisms underlying both neural activity and working memory ability in healthy individuals and a detailed knowledge of how to non-invasively interact with these mechanisms using brain stimulation. This will provide significant benefits such as the development of individually optimised brain stimulation protocols, enabling tailored approaches to reliably alter brain function and cognition.Read moreRead less
Expecting the unexpected: how people prioritise predictability. This project aims to investigate how people represent and use information about unpredictability in their environment. Seeing too much predictability is problematic, but seeing too little can also be a problem, for example inappropriate "learned helplessness" can occur, whereby people feel disempowered because the world is seen as random. Recent findings demonstrated a bias in fundamental learning that may maintain these inappropria ....Expecting the unexpected: how people prioritise predictability. This project aims to investigate how people represent and use information about unpredictability in their environment. Seeing too much predictability is problematic, but seeing too little can also be a problem, for example inappropriate "learned helplessness" can occur, whereby people feel disempowered because the world is seen as random. Recent findings demonstrated a bias in fundamental learning that may maintain these inappropriate beliefs about unpredictability. This bias is not anticipated by formal theories of learning. The project will investigate how this bias is brought about by first formalising a novel theory of fundamental learning and then systematically testing its assumptions.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.

Reconnecting the ageing brain to enhance plasticity and motor learning. The ability to execute and learn skillful actions deteriorates with advancing age, but the cause remains elusive. The main aim of this project is to use new neurophysiological techniques to examine the age-related changes in brain function that contribute to reduced movement control in healthy older adults. The research will use multimodal approaches to reveal the causal role of age-related changes in specific brain networks ....Reconnecting the ageing brain to enhance plasticity and motor learning.

The main aim of this project is to use new neurophysiological techniques to examine the age-related changes in brain function that contribute to reduced movement control in healthy older adults. The research will use multimodal approaches to reveal the causal role of age-related changes in specific brain networks to motor behaviour and learning. The outcomes will provide significant new knowledge that may help to optimise the design of targeted interventions aimed at rejuvenating brain function and movement quality in the elderly.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

This project aims to generate new knowledge about the impact of inadequate sleep and prolonged sitting on health markers and performance. Many workers, particularly those working outside standard hours, experience both prolonged sitting and inadequate sleep. Expected outcomes of this project include critical evidence to address the dual burden experienced by a large population of workers who are both sleepy and sitting. This should provide significant benefits for the many working Australians whose health and safety is compromised due to their exposure to inadequate sleep and prolonged sitting. It will also contribute to the evidence-base for workplace policies and public health guidelines.Read moreRead less
A more sound approach to the neurobiology of language. How does the brain attain spoken language? Current neurobiological models assume either implicitly or explicitly that there is no relationship between a word's sound and its meaning. Yet considerable evidence shows this strong assumption about the arbitrariness of language is invalid. This project will use a combination of behavioural, neuroimaging and computational studies to characterise how the brain processes statistical regularities in ....A more sound approach to the neurobiology of language. How does the brain attain spoken language? Current neurobiological models assume either implicitly or explicitly that there is no relationship between a word's sound and its meaning. Yet considerable evidence shows this strong assumption about the arbitrariness of language is invalid. This project will use a combination of behavioural, neuroimaging and computational studies to characterise how the brain processes statistical regularities in sound-to-meaning correspondences as probabilistic cues to attain spoken language. The outcome will be a better neural account of language comprehension and production. The benefit of this new account will be a stronger basis for assessment and treatment of developmental and acquired language impairments.Read moreRead less
