Language is essential to human interaction, yet we know comparatively little about the mental processes involved and how they are represented in the brain, how genetic and environmental factors contribute to the development of language, or how effective treatments of language disorders work. The significance of this program of research lies in its capacity to enhance our understanding of a range of mechanisms responsible for a fundamentally human ability, and provide information that will ultimately inform clinical practice. In particular, new knowledge about the brain mechanisms involved in language processing and recovery will inform clinicians about the optimal choice of treatment to maximise outcomes for the individual patient.

Summary
The brain, maths and space: their interaction in health and disease. This project investigates how thinking about numbers affects how we think about the space that surrounds us - and vice versa. Investigations of commonalities in the neural and cognitive processing of space and numbers may lead to the development of innovative therapies for people suffering from attentional disorders after brain damage.
Captions for the Deaf and Hearing Impaired: Availability versus Accessibility. The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings. These innovations must be matched by equally innovative ways of increasing the accessib ....Captions for the Deaf and Hearing Impaired: Availability versus Accessibility. The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings. These innovations must be matched by equally innovative ways of increasing the accessibility of captions, which is currently limited by English literacy, caption speed, and caption reduction techniques. Here, systematic manipulation of these factors in experiments on television captioning with adults and educational captioning with children will determine how resources might best be directed to improving caption accessibility.Read moreRead less
A longitudinal study of language learning to assess early intervention outcomes in pre-school children with impaired hearing. Overseas research suggests that young children with impaired hearing and normal non-verbal cognition can develop normal language if hearing aid fitting and intervention occur before 6 months of age. Australian studies show considerable language delays in most hearing-impaired children of primary-school age. We will study the spoken language learning of hearing-impaired ....A longitudinal study of language learning to assess early intervention outcomes in pre-school children with impaired hearing. Overseas research suggests that young children with impaired hearing and normal non-verbal cognition can develop normal language if hearing aid fitting and intervention occur before 6 months of age. Australian studies show considerable language delays in most hearing-impaired children of primary-school age. We will study the spoken language learning of hearing-impaired children up to age 6 years in Victoria. The project will investigate crucial factors in achieving normal language learning in hard-of-hearing children and the role of early intervention. Normal language outcomes would enhance the educational and career prospects of hearing-impaired children and result in community cost savings.

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
ELEMENTS: A Virtual-Reality Augmented Workspace for Movement Rehabilitation of Traumatic Brain Injury Patients. The broad aim of the project is to design, develop and evaluate an interactive virtual environment (VE) called ELEMENTS that supports movement assessment and rehabilitation for patients recovering from Traumatic Brain Injury (TBI). We will use current knowledge of the neural basis of movement control and learning to create VEs that will help re-train patients' sense of multimodal space ....ELEMENTS: A Virtual-Reality Augmented Workspace for Movement Rehabilitation of Traumatic Brain Injury Patients. The broad aim of the project is to design, develop and evaluate an interactive virtual environment (VE) called ELEMENTS that supports movement assessment and rehabilitation for patients recovering from Traumatic Brain Injury (TBI). We will use current knowledge of the neural basis of movement control and learning to create VEs that will help re-train patients' sense of multimodal space, their position within it, and the predictive control of actions. We will adapt our training environments for use on readily available technologies, creating a treatment method amenable to remote delivery. This will extend rehabilitation practices beyond their current constraints.Read moreRead less
The relationship between cognitive capacity and driver competence following acquired brain injury: Implications for driver rehabilitation and training. This project develops a model of driver rehabilitation and training, based on speed of information processing variables, for people with acquired brain injuries (ABI). Current evaluations of fitness to drive lack sufficient theoretical and empirical foundations. Consequent problems include inappropriate decisions about fitness to drive, comprom ....The relationship between cognitive capacity and driver competence following acquired brain injury: Implications for driver rehabilitation and training. This project develops a model of driver rehabilitation and training, based on speed of information processing variables, for people with acquired brain injuries (ABI). Current evaluations of fitness to drive lack sufficient theoretical and empirical foundations. Consequent problems include inappropriate decisions about fitness to drive, compromised driver safety, and inadequate driver training. Accurate assessment of ABI processing deficits will generate driver-training programs tailored to individual needs. The project also addresses rehabilitation and training outcomes, particularly as they relate to reduced social services needs and enhanced quality of life. It provides a paradigm for evaluating rehabilitation outcomes in wider contexts.

When immigrants and converts are not truly one of us: Examining the social psychology and developmental antecedents of marginalizing racism. Marginalizing Racism, the simultaneous acceptance and rejection of others, is clearly present in Australia. It is not just a matter of thugs on the streets of Cronulla, but of elected politicians expressing Marginalizing Racist views.

Marginalizing Racism, the simultaneous acceptance and rejection of others, is clearly present in Australia. It is not just a matter of thugs on the streets of Cronulla, but of elected politicians expressing Marginalizing Racist views. We believe that examining the social psychology and developmental causes of this insidious form of racism will pave the way for positive social change. This is not just an academic exercise, but a chance to expose and tackle a form of racism to which the broader public and our own profession appears to turn a blind eye. Moreover, as we expect this research to yield timely and influential discoveries, it will help maintain Australia's position as a world leader in the field of social psychology.Read moreRead less
Children's Intergroup Prejudice: The Roles of Cognitive Representations and Self-presentation. Research indicates that intergroup prejudice remains a problem in most Australian schools. For example, children as young as 5-6 years assign negative attributes to indigenous Australians and Pacific Islander children, they prefer not to play with these children, and they do not even want them living nearby. The proposed research will examine the possible basis of age effects in these attitudes. It wi ....Children's Intergroup Prejudice: The Roles of Cognitive Representations and Self-presentation. Research indicates that intergroup prejudice remains a problem in most Australian schools. For example, children as young as 5-6 years assign negative attributes to indigenous Australians and Pacific Islander children, they prefer not to play with these children, and they do not even want them living nearby. The proposed research will examine the possible basis of age effects in these attitudes. It will have a substantial national benefit because it will increase our understanding of this insidious social phenomenon and provide a basis for developing an intervention that will minimise a problem that has the potential to devastate community relations.
