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

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. 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 b ....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. 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

This research will determine the brain circuits responsible for language production and how this process is affected in Parkinson's disease.
Children's Changing Speech Error Patterns: Articulating, Listening, and Thinking. When children are learning to talk, they make many errors of pronunciation. Between speech onset and five years of age, their pronunciations change, gradually approaching adult pronunciations of words. Most children share the same error patterns, although 6% have difficulty acquiring intelligible speech, that affects their academic and social development. The investigation will examine factors that contribute to ....Children's Changing Speech Error Patterns: Articulating, Listening, and Thinking. When children are learning to talk, they make many errors of pronunciation. Between speech onset and five years of age, their pronunciations change, gradually approaching adult pronunciations of words. Most children share the same error patterns, although 6% have difficulty acquiring intelligible speech, that affects their academic and social development. The investigation will examine factors that contribute to the acquisition of speech in normally developing and speech-disordered populations: oro-motor skills, auditory and cognitive processing. Experiments will determine the importance of each domain for speech development. The efficacy of a novel intervention programme for children with speech disorders will be evaluated.Read moreRead less

Back and neck pain are major health issues and are associated with considerable cost to society and an individual's quality of life. A major issue is to identify factors that increase the chance of developing pain. This project will investigate a novel and innovative possibility; that competition between the many functions of the trunk muscles may increase the possibility for injury. We will study how the nervous system coordinates functions as diverse and movement of the spine, breathing, and control of head and eye movement. A key issue will be to identify whether situations arise in which control of the spine is compromised, potentially leading to increased risk of pain and injury. Such data can aid prevention and rehabilitation.Read moreRead less
