In order for people to read effectively, the mental representation of each letter-string must be found in long-term memory. The aim of this project is to more fully understand the nature of proficient visual word recognition with a particular focus on the way in which the form of the word is mentally stored and retrieved during the act of reading. A range of issues will be examined from letter position coding through to how words with a complex internal structure are processed, all framed within a unified model of word recognition. An understanding of the mechanisms underlying proficient adult reading is significant and beneficial in that it is expected to provide a framework for guiding both reading acquisition and reading improvement programs.Read moreRead less
When reading takes off: Children's word learning during independent reading. This project aims to address the major unsolved problem of how children build their knowledge about printed words through their reading. This is important since, once children have been taught the basics of reading, the primary means by which they learn new words is through reading experience. The project will use innovative technology to monitor children’s eye movements as they encounter new words during reading, exami ....When reading takes off: Children's word learning during independent reading. This project aims to address the major unsolved problem of how children build their knowledge about printed words through their reading. This is important since, once children have been taught the basics of reading, the primary means by which they learn new words is through reading experience. The project will use innovative technology to monitor children’s eye movements as they encounter new words during reading, examining factors influencing real-time cognitive processing and ongoing learning. Expected outcomes will be new insights into how to optimise children’s word learning when reading, and the refinement of a new computational model. These will inform policy and practice in reading instruction, to the benefit of Australia's children.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.
Cracking the orthographic code: investigating early perceptual processes in reading. Current understanding of how human readers decode a string of letters into known words is inadequate. This project advances understanding of this early reading process, by combining computational modelling, behavioural and brain imaging approaches.
The flipside of noise: Does it benefit listening and learning? People with low attention capacity can experience improvements in cognitive function (eg memory) in the presence of external white noise. This project aims to determine the brain mechanisms for this improvement and how it affects oral language comprehension and verbal learning. In doing so, the research would change the prevailing view that noise is always detrimental to mental processes, and provide a theoretical framework for predi ....The flipside of noise: Does it benefit listening and learning? People with low attention capacity can experience improvements in cognitive function (eg memory) in the presence of external white noise. This project aims to determine the brain mechanisms for this improvement and how it affects oral language comprehension and verbal learning. In doing so, the research would change the prevailing view that noise is always detrimental to mental processes, and provide a theoretical framework for predicting how an individual’s cognitive capacity is affected by the presence of noise. It may support the development of methods to improve educational participation and outcomes for children, particularly those with lower attention, and for older adults.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
The perception/production link in child language. Children with hearing loss experience continuing language difficulties, with major knock-on effects on educational and social outcomes. This project aims to uncover the connected perception and production processes that underpin these language challenges for children with hearing loss, focussing on a speech patterns also found in younger normal-hearing toddlers, and using innovative technologies that can generalize to the clinical practice. The p ....The perception/production link in child language. Children with hearing loss experience continuing language difficulties, with major knock-on effects on educational and social outcomes. This project aims to uncover the connected perception and production processes that underpin these language challenges for children with hearing loss, focussing on a speech patterns also found in younger normal-hearing toddlers, and using innovative technologies that can generalize to the clinical practice. The project outcomes will significantly advance theories of child language development, and promise to inform more accurate and better-targeted intervention for children with hearing loss, providing social benefit by improving their listening and speaking skills.Read moreRead less
Beyond reading jumbled words: Bridging perception and language in the Noisy Channel model. Classic computational models of visual word recognition do not consider the noise present in early perceptual processes, and they cannot cope with “jubmled wrods”- words with distorted letter order, unlike skilled readers. Previous work has developed the Noisy Channel model which can recognise such words, modelled as an optimal Bayesian inference process operating on a noisy visual input where there is unc ....Beyond reading jumbled words: Bridging perception and language in the Noisy Channel model. Classic computational models of visual word recognition do not consider the noise present in early perceptual processes, and they cannot cope with “jubmled wrods”- words with distorted letter order, unlike skilled readers. Previous work has developed the Noisy Channel model which can recognise such words, modelled as an optimal Bayesian inference process operating on a noisy visual input where there is uncertainty in the identity and order of letters. In this project, using computational modeling and behavioural experiments, the scope of the Noisy Channel model will be extended to address the role of phonology in the early stages of reading. The outcome will be a better understanding of the link between visual perception and language.Read moreRead less

Disorders in the production and comprehension of spoken and written language affect 15% of children and if untreated persist through adulthood. They are powerfully influenced by genetics, but are uniquely dependent on learning. This initiative aims to create a network unique in the world by uniting researchers with expertise in research from infancy through adulthood, in diagnosis and in treatment, in spoken and written production and comprehension, and in both cognitive and molecular genetic research. A network of research-oriented clinics for the treatment of these disorders will also be established.Read moreRead less
