Does word similarity across languages help or hinder bilingual speakers? This project aims to understand in more detail how bilinguals can accurately speak in both their languages. Speaking is a complex skill, particularly if you have two languages to choose from, which will be true for over half of Australia’s population by 2025. This project aims to investigate the factors that influence speech production in both monolinguals and bilinguals including those with language impairment, and develop ....Does word similarity across languages help or hinder bilingual speakers? This project aims to understand in more detail how bilinguals can accurately speak in both their languages. Speaking is a complex skill, particularly if you have two languages to choose from, which will be true for over half of Australia’s population by 2025. This project aims to investigate the factors that influence speech production in both monolinguals and bilinguals including those with language impairment, and develop a better bilingual theory. The benefit of this new theory will be to provide a clear basis for diagnosis and treatment for children in bilingual households who have problems learning to speak, and for bilingual people with language problems after a stroke or dementia.Read moreRead less
Beyond Speech: Towards better communication for children with hearing loss. Despite the benefits of early newborn hearing screening and early intervention programs for children with hearing loss, most still experience academic and social challenges at school. This is partly due to ongoing listening effort, leading to communicative breakdown. This project aims to identify the locus of the communicative challenges these children face during daily discourse interactions. The outcomes will identify ....Beyond Speech: Towards better communication for children with hearing loss. Despite the benefits of early newborn hearing screening and early intervention programs for children with hearing loss, most still experience academic and social challenges at school. This is partly due to ongoing listening effort, leading to communicative breakdown. This project aims to identify the locus of the communicative challenges these children face during daily discourse interactions. The outcomes will identify which levels of language are most compromised and will inform future interventions to reduce children’s listening effort. This will be undertaken by bringing together researchers in basic science with hearing service providers, parents and industry, providing an innovative model for solving multidisciplinary challenges.Read moreRead less
How the brain produces speech: Neuronal oscillations to neuromodulation. Speech is crucial for facilitating human communication through language, yet there is a lack of clarity about where, when and what type of activity occurs in the brain during key stages of production. This project will use intracranial recordings to characterise neuronal oscillations in combination with direct electrical stimulation, functional neuroimaging and non-invasive brain stimulation to establish critical areas and ....How the brain produces speech: Neuronal oscillations to neuromodulation. Speech is crucial for facilitating human communication through language, yet there is a lack of clarity about where, when and what type of activity occurs in the brain during key stages of production. This project will use intracranial recordings to characterise neuronal oscillations in combination with direct electrical stimulation, functional neuroimaging and non-invasive brain stimulation to establish critical areas and their timecourses with millisecond resolution. The outcome will be a better theoretical account of the brain mechanisms involved in spoken production. The benefit of this new theoretical account will be a better basis for prevention of post-surgical language impairment and neuromodulatory treatments after brain injury.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
How satiation control reward value and cue-induced appetitive behaviours. This proposal aims to identify mechanisms that control environment-driven food-seeking behaviours. It seeks to do so by using modern virally-mediated and basic behavioural as well as histological techniques in a transgenic rat to characterise novel hindbrain circuits that control these feeding behaviours. This is significant as environment-driven overeating is problematic yet underlying mechanisms are unclear. This project ....How satiation control reward value and cue-induced appetitive behaviours. This proposal aims to identify mechanisms that control environment-driven food-seeking behaviours. It seeks to do so by using modern virally-mediated and basic behavioural as well as histological techniques in a transgenic rat to characterise novel hindbrain circuits that control these feeding behaviours. This is significant as environment-driven overeating is problematic yet underlying mechanisms are unclear. This project expects to provide new knowledge on when, where and how hindbrain neurons control environment-driven food-seeking behaviours. This should provide benefits to the advancement of knowledge on the neural mechanisms of food-seeking and provide a basic science platform for future research on the study of feeding behaviours.

The development of predictive brain function in preschool children. This project aims to track developmental changes in brain activity and connectivity in typically developing three-to-six year-old children. The preschool years are a time of huge change in children's cognitive abilities, but little is known of the corresponding changes in brain function. This work will use child-optimised magnetoencephalography to test the hypothesis that early cognitive development is characterised by refinemen ....The development of predictive brain function in preschool children. This project aims to track developmental changes in brain activity and connectivity in typically developing three-to-six year-old children. The preschool years are a time of huge change in children's cognitive abilities, but little is known of the corresponding changes in brain function. This work will use child-optimised magnetoencephalography to test the hypothesis that early cognitive development is characterised by refinement of the brain's innate ability to generate predictions about the sensory environment. The resulting insights could improve understanding of neurodevelopmental disorders such as autism.Read moreRead less

Hippocampal regulation of goal-directed decision-making. The hippocampus is a part of the brain that is central to learning and memory yet little is known about its role in decision-making. It is the aim of this application to provide the first detailed, causal evidence of hippocampal regulation of decision-making. This is significant because many mental health disorders and dementias that involve decision-making deficits are characterised by hippocampal dysfunction, but any direct link between ....Hippocampal regulation of goal-directed decision-making. The hippocampus is a part of the brain that is central to learning and memory yet little is known about its role in decision-making. It is the aim of this application to provide the first detailed, causal evidence of hippocampal regulation of decision-making. This is significant because many mental health disorders and dementias that involve decision-making deficits are characterised by hippocampal dysfunction, but any direct link between these factors is unknown. The outcomes of the current grant will provide the first evidence of that link, thus providing deeper understanding of the neurophysiological mechanisms of these disorders, which could eventuate in the creation of more beneficial treatments.

Learning to read and understand complex words. This project aims to study the development of morphological reading skills from kindergarten through to high school, providing insights into the full spectrum of abilities required to move from novice to expert reader. Over 80 per cent of English words comprise multiple morphemes, but how children learn to read such complex words is not well understood. Understanding this key reading process will have the potential to inform reading instruction prac ....Learning to read and understand complex words. This project aims to study the development of morphological reading skills from kindergarten through to high school, providing insights into the full spectrum of abilities required to move from novice to expert reader. Over 80 per cent of English words comprise multiple morphemes, but how children learn to read such complex words is not well understood. Understanding this key reading process will have the potential to inform reading instruction practices from primary school through to high school. Expected outcomes are a richer understanding of the predictors, developmental time-course, and mechanisms involved in the acquisition of morphological processes in reading. This project has the potential to inform the effectiveness of explicit morphological teaching and intervention, to the benefit of Australia’s children.Read moreRead less
