Audio-visual Information for Speech-hand Gestures. How does audio-visual information influence human movement and communication? We will investigate whether speech and hand gestures involve shared information about the timing of rhythmic movements. Using dynamical systems theory and brain imaging techniques, we will study rhythms that emerge during simultaneous speaking and finger tapping in both stutterers and non-stutterers, and in left-handers and right-handers. The communicative interaction ....Audio-visual Information for Speech-hand Gestures. How does audio-visual information influence human movement and communication? We will investigate whether speech and hand gestures involve shared information about the timing of rhythmic movements. Using dynamical systems theory and brain imaging techniques, we will study rhythms that emerge during simultaneous speaking and finger tapping in both stutterers and non-stutterers, and in left-handers and right-handers. The communicative interaction of two persons performing speech-hand gestures will be examined. Results will clarify how brain asymmetry affects gestural coordination in stutterers, how stuttering can be treated, and the hypothesis that speech and language evolved from a communication system based on hand gestures.

Functional Assessment of Head-eye Coordination during Driving. 238 people per 100,000 population were hospitalized and 9 people per 100,000 died as a result of road-transport related injury in Australia in 2002. We will address this issue by assessing the head eye coordination strategies for young drivers, for proficient drivers and for aged drivers to determine those behaviors and strategies that are associated with various levels of performance. This insight could be affectively communicated t ....Functional Assessment of Head-eye Coordination during Driving. 238 people per 100,000 population were hospitalized and 9 people per 100,000 died as a result of road-transport related injury in Australia in 2002. We will address this issue by assessing the head eye coordination strategies for young drivers, for proficient drivers and for aged drivers to determine those behaviors and strategies that are associated with various levels of performance. This insight could be affectively communicated to others and would provide the basis for educational material and methods that would improve operator skill, safety, and performance. These individual improvements would provide overall benefits such as improved transport efficiency, reduced accident rates, saved lives and a reduction in related social costs.Read moreRead less
Interlimb coordination dynamics in stroke. Everyday we use our limbs in a coordinated manner. However, for a person who has suffered a stroke resulting in weakness on one side of the body even the simplest interlimb coordination tasks are difficult to perform. This project will examine interlimb coordination in persons who have suffered a stroke and explore whether the coupling between limbs can be exploited to promote fuctional recovery of an impaired limb. In particular, the research seeks to ....Interlimb coordination dynamics in stroke. Everyday we use our limbs in a coordinated manner. However, for a person who has suffered a stroke resulting in weakness on one side of the body even the simplest interlimb coordination tasks are difficult to perform. This project will examine interlimb coordination in persons who have suffered a stroke and explore whether the coupling between limbs can be exploited to promote fuctional recovery of an impaired limb. In particular, the research seeks to identify the critical components underlying the effectiveness of an intervention involving the pratice of actions bilaterally and simultaneously.Read moreRead less
Developmental trajectory of tongue control for speech with real-time MRI. This project aims to evaluate the developmental trajectory of tongue control during speech, relating dynamic 3D vocal tract modelling to the acoustic signal. By optimising real-time MRI technology to capture and model articulatory movements, the project expects to accelerate understanding of how tongue control for speech is developed, mastered, and perturbed by factors such as rapid growth and foreign accent. Expected outc ....Developmental trajectory of tongue control for speech with real-time MRI. This project aims to evaluate the developmental trajectory of tongue control during speech, relating dynamic 3D vocal tract modelling to the acoustic signal. By optimising real-time MRI technology to capture and model articulatory movements, the project expects to accelerate understanding of how tongue control for speech is developed, mastered, and perturbed by factors such as rapid growth and foreign accent. Expected outcome is a new understanding of how different speakers' vocal tracts change and how speech is reshaped, informed by real physiological data. Significant benefits will be realised through refined methods and theory development for diverse fields e.g. linguistics, speech science, and automatic speech recognition/synthesis.

Revealing the beneficial effects of acoustic stimulation on the human brain. This project aims to provide greater understanding of the neural mechanisms by which initiation of motor responses can be improved by unexpected auditory stimulation. Initiating motor actions appears natural and effortless, but is underpinned by complex neural mechanisms that are not well understood. Using novel brain stimulation techniques, the project aims to assess the potential for properly timed strong sensory stim ....Revealing the beneficial effects of acoustic stimulation on the human brain. This project aims to provide greater understanding of the neural mechanisms by which initiation of motor responses can be improved by unexpected auditory stimulation. Initiating motor actions appears natural and effortless, but is underpinned by complex neural mechanisms that are not well understood. Using novel brain stimulation techniques, the project aims to assess the potential for properly timed strong sensory stimulation during movement preparation to induce neural plasticity and motor learning. This knowledge would have important implications across a number of fields, including neuroscience, sports science, and applied ergonomics.Read moreRead less

Summary
The predictive brain and control of anticipatory actions. The ability to predict events in a dynamic environment is an important skill for survival as it can guide our actions when time pressures are severe. How predictions come about to guide our actions is not clear and project results will have great theoretical significance to understand how we generate them.
The genetic and diagnostic relationship between motor control and Attention Deficit Hyperactivity Disorder. Children with Attention Deficit Hyperactivity Disorder (ADHD) often have comorbid Developmental Coordination Disorder (DCD). This project will utilise the expertise of leading researchers in Australia and the Netherlands to investigate the genetic and diagnostic relationship between these two disorders utilising a large sample of twins and their siblings.

Children with Attention Deficit Hyperactivity Disorder (ADHD) often have comorbid Developmental Coordination Disorder (DCD). This project will utilise the expertise of leading researchers in Australia and the Netherlands to investigate the genetic and diagnostic relationship between these two disorders utilising a large sample of twins and their siblings. We will examine the neuropsychological functioning in these groups of children in order to gain a better understanding of their genetic relationship. These findings will provide insight into the current DSM-IV classification of these disorders compared with other models used to investigate the relationship between poor motor coordination and ADHD.Read moreRead less
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.
How brain oscillations influence our behaviour. This project aims to reveal how sudden, intense stimuli impair or facilitate concurrent actions. Startling sounds can disrupt the execution of movements and distract attention from vital events in the environment, with potential disastrous consequences when handling complex equipment such as airplanes, cars and trucks, or surgical instruments. This project will combine classic experimental and novel neuro-modulatory techniques with the measurement ....How brain oscillations influence our behaviour. This project aims to reveal how sudden, intense stimuli impair or facilitate concurrent actions. Startling sounds can disrupt the execution of movements and distract attention from vital events in the environment, with potential disastrous consequences when handling complex equipment such as airplanes, cars and trucks, or surgical instruments. This project will combine classic experimental and novel neuro-modulatory techniques with the measurement of oscillatory brain activity. Expect outcomes will inform theories of cognitive function and the design of interventions to reduce the negative effects of sudden, distracting events.Read moreRead less
