An investigation of respiration in stuttering. Australia leads the world in stuttering research, and this project will maintain that profile. The research aims to establish if breathing has a causal role in stuttering. The new knowledge produced will support or weaken current theories of the cause of stuttering and will contribute to understanding the nature of the disorder. In particular, it will be applied to develop more effective and efficient treatments for chronic stuttering.
Establishing the relationship between anxiety and stuttering. The present project will establish basic knowledge about the disorder of stuttering, which will contribute to offsetting the personal and community costs of the disorder by guiding empirical investigations into its nature and the development of future treatments. Further benefits at the population level will occur by provision to the public of basic information about the disorder assembled from this project.

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
The language abilities of young offenders: Missing links in theory and practice.. Young offenders are a complex and challenging population, with high rates of comorbidity between attentional, learning, and behaviour problems. Few workers have, however, considered the underlying language processing and production skills in this population. Available evidence indicates a high level of vulnerability to language disorders in young offenders. These may contribute to poor academic performance and fail ....The language abilities of young offenders: Missing links in theory and practice.. Young offenders are a complex and challenging population, with high rates of comorbidity between attentional, learning, and behaviour problems. Few workers have, however, considered the underlying language processing and production skills in this population. Available evidence indicates a high level of vulnerability to language disorders in young offenders. These may contribute to poor academic performance and failure to develop prosocial skills. This study will explore language competencies and will describe their relationship to social skills, patterns of comorbidity, and type of offence (property Vs violent). Findings will be relevant to theories of juvenile offending and design of prevention/intervention programsRead moreRead less

Relationship of retinal directionality to human retinal anatomy variations. This project aims to improve measurement of retinal directionality, which is the reduction in brightness when a light beam’s entry into the human eye is shifted from the centre to the edge of the pupil. This influences retinal image quality and can be used to measure changes in shape of the peripheral eye. This project will apply advanced technologies in holography, and heads-up displays to explore how retinal directiona ....Relationship of retinal directionality to human retinal anatomy variations. This project aims to improve measurement of retinal directionality, which is the reduction in brightness when a light beam’s entry into the human eye is shifted from the centre to the edge of the pupil. This influences retinal image quality and can be used to measure changes in shape of the peripheral eye. This project will apply advanced technologies in holography, and heads-up displays to explore how retinal directionality changes during accommodation (focusing). The expected outcome is improved understanding of retinal stretching changes during focusing. The benefit is that the project will lead to advancements in retinal imaging.Read moreRead less
