Speaking my language: International speech acquisition in Australia. It is important to differentiate between children who have communication impairment (difficulty learning all languages) from those who only have difficulty learning subsequent language(s). Communication impairment in multilingual children is both undiagnosed and over-diagnosed due to lack of culturally-sensitive measurement tools. Early intervention can ameliorate communication impairment in children and can reduce subsequent e ....Speaking my language: International speech acquisition in Australia. It is important to differentiate between children who have communication impairment (difficulty learning all languages) from those who only have difficulty learning subsequent language(s). Communication impairment in multilingual children is both undiagnosed and over-diagnosed due to lack of culturally-sensitive measurement tools. Early intervention can ameliorate communication impairment in children and can reduce subsequent educational, social and occupational outcomes of untreated communication impairment. By working with people around the world, this Fellowship will result in the development of the International Speech Assessment designed to differentially identify children and to specify holistic early intervention goals.Read moreRead less
Illuminating the Language-specific and Physiological Motor-control Influences on Children's Production of Lexical Stress. Great progress has been made in understanding the production of individual speech sounds but much less is known about the production of prosody. Lexical stress is a type of prosody that reflects the contrast between strong and weak syllables within single words. The ability to achieve this contrastivity shows a protracted developmental trajectory in healthy children and is at ....Illuminating the Language-specific and Physiological Motor-control Influences on Children's Production of Lexical Stress. Great progress has been made in understanding the production of individual speech sounds but much less is known about the production of prosody. Lexical stress is a type of prosody that reflects the contrast between strong and weak syllables within single words. The ability to achieve this contrastivity shows a protracted developmental trajectory in healthy children and is atypical in some children with autism. How these developmental influences relate to language-specific versus physiological motor-control factors is unknown. This project will address this critical research problem via innovative acoustic investigations. Outcomes will trigger the next generation of speech production models with potential for impact in areas like speech pathology.Read moreRead less
Developing better treatments for language disorders. This project will enable better treatment of people with disorders affecting language such as aphasia, dyslexia, and dementia. It will achieve this through development of more detailed theories of language processing, better assessment of language disorders and a better understanding of how treatments for language disorders have their effects.
A new model of human speech production through computational modeling and human functional brain imaging. It is still largely a mystery how we convert our thoughts into fluent intelligible speech. This project will bring together experts in speech pathology, neuroscience, and computer modeling to create a new biologically-plausible model of speech production to advance understanding of speech development, ageing, and mechanisms of recovery after injury.
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
Parallel and generative binding in human visual cortex. Imagine watching a group of children running around in brightly coloured T-shirts. How does your brain keep track of which colour goes with which T-shirt goes with which child? This project will use magnetic resonance imaging to identify where in our brains information about colour, shape and motion gets put together.
Lipidomics of vision. Presbyopia and cataract are the major causes of visual impairment worldwide. Nevertheless, our understanding of lens ageing at both a cellular and molecular level is limited. This project will gain new insight into the effect of age on lens membrane lipids and their role in the development of presbyopia and cataract.
Seeing the forest and the trees: Cognitive and neural mechanisms underlying recognition of individual objects and sets. When confronted with a set of similar objects, such as a crowd of faces or a flow of oncoming cars, human observers can rapidly and seemingly automatically extract summary statistics of these sets of objects (e.g., mean expression or location). This research will provide insights into how the human visual system executes this massive feat of computation. This represents a vital ....Seeing the forest and the trees: Cognitive and neural mechanisms underlying recognition of individual objects and sets. When confronted with a set of similar objects, such as a crowd of faces or a flow of oncoming cars, human observers can rapidly and seemingly automatically extract summary statistics of these sets of objects (e.g., mean expression or location). This research will provide insights into how the human visual system executes this massive feat of computation. This represents a vital step in understanding vision in general and in eventually applying our knowledge to the development of artificial vision systems and to rehabilitation of visual disorders. The research will also investigate the effects of attentional load on perception of summary statistics of the environment, which is critical for tasks such as driving in busy traffic.Read moreRead less
Understanding bilingual language acquisition in northern Indigenous Australia: phonological, lexical, orthographic, and family factors. Children's language outcomes are critical for health, social inclusion, education and employment. In northern Australia many Indigenous children grow up as Kriol/English bilinguals in disadvantaged communities; this research will establish the linguistic, educational, and family factors in successful language acquisition for these children.
New laser-based approaches for remote sensing of water properties. New approaches for remote sensing of water properties such as temperature and salinity will be developed. Outcomes such as rapid vertical profiling of water temperature and salinity will contribute to environmental issues such as climate change and waterway health, while the ability to measure tissue temperature will contribute to human health.
