Testing the Modularity of Memory. Researchers disagree about whether verbal and visual working memory (WM) storage occurs in separate modules. Recent evidence suggests that only verbal memoranda have access to a specialised module, while visual memories make use of more general resources. This project aims to re-examine interference between verbal and visual memoranda using statistical methods specialised for assessing whether multiple latent factors underlie performance on recognition memory ta ....Testing the Modularity of Memory. Researchers disagree about whether verbal and visual working memory (WM) storage occurs in separate modules. Recent evidence suggests that only verbal memoranda have access to a specialised module, while visual memories make use of more general resources. This project aims to re-examine interference between verbal and visual memoranda using statistical methods specialised for assessing whether multiple latent factors underlie performance on recognition memory tasks, examining adult and child populations. This is expected to influence applications of WM theory in many everyday settings, resulting in improvements in educational practices, workplace procedures, and clinical treatments that depend on theoretical understandings of limits in cognition.Read moreRead less

Summary
Neural mechanisms of inhibitory control of human speech in stutterers and non-stutterers. Stopping oneself from speaking is a crucial communication function. In people who stutter, a disorder of this function causes their debilitating speech problem. This project will use cutting edge neuroimaging techniques to reveal how the brain stops speech in stutterers and in fluent speakers.
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
Epigenetic mechanisms regulating sex differences in fear-related learning and memory. Anxiety disorders represent an enormous burden on society and are associated with premature aging and infertility in men and women. Evidence also indicates that parental anxiety affects child development. Given that fear-related learning has an important influence on emotional health which, in turn, affects lifestyle and the aging process, an understanding of the neural mechanisms mediating sex differences in ....Epigenetic mechanisms regulating sex differences in fear-related learning and memory. Anxiety disorders represent an enormous burden on society and are associated with premature aging and infertility in men and women. Evidence also indicates that parental anxiety affects child development. Given that fear-related learning has an important influence on emotional health which, in turn, affects lifestyle and the aging process, an understanding of the neural mechanisms mediating sex differences in fear learning will enhance our ability to develop better therapeutic approaches for treating anxiety and preventing relapse, potentially through a gender-specific approach. The studies outlined in this proposal will have implications for promoting and maintaining good health.Read moreRead less

I can't find the word! Reading to maintain communication skills in ageing. This project aims to investigate why, as we age, we have trouble retrieving words when we speak but not when we read aloud. It takes the novel approach of systematically testing both reading and speaking in the same older adults. Through its innovative use of both behavioural research and computational modelling, it will generate new knowledge in spoken word production and reading, areas in which the project team have ack ....I can't find the word! Reading to maintain communication skills in ageing. This project aims to investigate why, as we age, we have trouble retrieving words when we speak but not when we read aloud. It takes the novel approach of systematically testing both reading and speaking in the same older adults. Through its innovative use of both behavioural research and computational modelling, it will generate new knowledge in spoken word production and reading, areas in which the project team have acknowledged expertise. This project will advance theories, achieving understanding of how ageing affects the cognitive systems involved in saying words and reading them aloud. By also investigating whether reading aloud can support word retrieval, it has potential future benefit for improved communication in older adults.Read moreRead less
Using large scale modelling to understand reading development and dyslexia. This project aims to construct a computational model of reading that makes quantitative predictions about reading behaviour and dyslexia. It will test theories of reading development and dyslexia based on what they predict in terms of reading performance, predictions which many theories of dyslexia do not make. The model will be in English, French and Italian, which offer rich and constraining data to test the model. The ....Using large scale modelling to understand reading development and dyslexia.

It will test theories of reading development and dyslexia based on what they predict in terms of reading performance, predictions which many theories of dyslexia do not make. The model will be in English, French and Italian, which offer rich and constraining data to test the model. The project is expected to explain the link between reading performance and underlying influences and why dyslexia manifests differently in different languages.Read moreRead less
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

This project aims to evaluate the developmental trajectory of tongue control during speech, relating dynamic 3D vocal tract modelling to the acoustic signal. By optimising real-time MRI technology to capture and model articulatory movements, the project expects to accelerate understanding of how tongue control for speech is developed, mastered, and perturbed by factors such as rapid growth and foreign accent. Expected outcome is a new understanding of how different speakers' vocal tracts change and how speech is reshaped, informed by real physiological data. Significant benefits will be realised through refined methods and theory development for diverse fields e.g. linguistics, speech science, and automatic speech recognition/synthesis. Read moreRead less
