Completion of this project will depend upon international collaboration - forging links between a young Australian investigator and outstanding overseas scientists as well as providing excellent training opportunities. Subsequent publication of the research in top-ranking international journals will further promote Australian science abroad.
Enhancing Language Learning in Ageing With Exercise. This project aims to determine if exercise improves language learning and consolidation in ageing. There is now compelling evidence for the benefits of exercise on cognition in older adults, however, it is unclear whether exercise improves age-related language problems. The project plans to examine exercise-induced changes in brain activity and biomarkers in an innovative set of studies that seeks to identify the brain mechanisms involved. The ....Enhancing Language Learning in Ageing With Exercise. This project aims to determine if exercise improves language learning and consolidation in ageing. There is now compelling evidence for the benefits of exercise on cognition in older adults, however, it is unclear whether exercise improves age-related language problems. The project plans to examine exercise-induced changes in brain activity and biomarkers in an innovative set of studies that seeks to identify the brain mechanisms involved. The findings are expected to contribute to theories of word learning and cognitive ageing and should advance our understanding of how exercise may be harnessed to optimise language and cognition. This would have practical applications in a range of populations with language and learning difficulties.Read moreRead less
Square Eyes or All Lies? Understanding Children's Exposure to Screens. This project will examine Australian parents’ number one concern about their children’s health and behaviour – their interactions with electronic screens. Current screen time guidelines are based on low-quality evidence and lack the nuance required to address this complex issue. This project will use innovative technology to resolve these weaknesses. Wearable cameras will measure what children are doing on screens, and where, ....Square Eyes or All Lies? Understanding Children's Exposure to Screens. This project will examine Australian parents’ number one concern about their children’s health and behaviour – their interactions with electronic screens. Current screen time guidelines are based on low-quality evidence and lack the nuance required to address this complex issue. This project will use innovative technology to resolve these weaknesses. Wearable cameras will measure what children are doing on screens, and where, when, and how long they are doing it. The project will also investigate how screen time impacts children’s development and how it is influenced by their environment. This evidence will benefit children by improving screen time guidelines, and help parents understand the impact of screen time on children’s development.

Sleep and speech: objectively monitoring the residual effects of sleep promoting compounds. This project will benefit the one in 11 Australians with sleep difficulties. The project will improve how the safety of drugs for insomnia are evaluated by examining the changes in our speech that occur when we are impaired. The findings are expected to reduce the cost of accidents and injuries due to impairment from sleep medications.
How the brain produces speech. Speech production is a fundamental ability that enables human interaction through language. Brain injuries impair this ability, with profound negative consequences for the individual and their immediate family and friends. This project will increase our understanding of the brain mechanisms involved in producing speech by using state-of-the-art brain imaging techniques. The findings will inform future clinical research and improve the advice given to clinicians, pa ....How the brain produces speech. Speech production is a fundamental ability that enables human interaction through language. Brain injuries impair this ability, with profound negative consequences for the individual and their immediate family and friends. This project will increase our understanding of the brain mechanisms involved in producing speech by using state-of-the-art brain imaging techniques. The findings will inform future clinical research and improve the advice given to clinicians, patients and the broader community about the nature of language production and its impairments and ultimately the treatment of speech disorders.Read moreRead less
The Ins and Outs of the Central Bottleneck. Humans display severe capacity limitations at multiple levels of information processing. When considering, with modern technological advances, the amount of multitasking one is called upon to do in every day life (e.g., talking on a hands-free mobile phone device and driving) it is vital to understand what stages of information processing interfere with one another. The present work will extend our knowledge regarding which cognitive operations can be ....The Ins and Outs of the Central Bottleneck. Humans display severe capacity limitations at multiple levels of information processing. When considering, with modern technological advances, the amount of multitasking one is called upon to do in every day life (e.g., talking on a hands-free mobile phone device and driving) it is vital to understand what stages of information processing interfere with one another. The present work will extend our knowledge regarding which cognitive operations can be performed concurrently without impairment. In addition, it will help us better understand processing limitations that have been linked to a variety of clinical groups such as those suffering from schizophrenia and mood disorders.Read moreRead less
How does dopamine modulate adult new word learning? Stroke is a chronic disease of increasing prevalence with increasing age. There is a critical need to develop more effective treatments of communication disorders in this population. One way of achieving this is to combine certain drugs with language therapy.

Stroke is a chronic disease of increasing prevalence with increasing age. There is a critical need to develop more effective treatments of communication disorders in this population. One way of achieving this is to combine certain drugs with language therapy. Through studying how these drugs influence language, this research will provide vital knowledge for developing effective forms of pharmacotherapy for adults with language disorders after brain injury. More effective language rehabilitation can have direct positive consequences on the ability to regain and maintain employment and social relationships after stroke or brain injury and will address the large and growing social and economic cost to the nation.Read moreRead less
A functional imaging study of semantic processing modulated by dopamine. The role of dopamine in language processing is largely unknown, despite emerging evidence that dopaminergic alterations can modulate language in schizophrenia, Parkinson's disease, and healthy individuals. The research aims to reveal the neural and behavioural correlates of dopaminergic modulation of semantic processing using neuroimaging in healthy individuals who have ingested levodopa. It is hypothesised that levodopa wi ....A functional imaging study of semantic processing modulated by dopamine. The role of dopamine in language processing is largely unknown, despite emerging evidence that dopaminergic alterations can modulate language in schizophrenia, Parkinson's disease, and healthy individuals. The research aims to reveal the neural and behavioural correlates of dopaminergic modulation of semantic processing using neuroimaging in healthy individuals who have ingested levodopa. It is hypothesised that levodopa will modulate brain activity under circumstances where there is heightened semantic competition, consistent with a contemporary theory of dopaminergic cognitive control. The expected outcome of the research is an increased understanding of the interactions between dopamine, the language faculty, and associated neural systems.Read moreRead less
