Social outcomes, behaviour and emotional well-being of adults with autism. It is recognised that autism results in substantial life-long disability. Severe emotional and behavioural problems are likely to be a key factor in precluding adults with autism from work, independent living, social contact, and undermine their quality of life, thus increasing support needs. This project aims to address a major gap in our current knowledge - the association between severe emotional and behavioural proble ....Social outcomes, behaviour and emotional well-being of adults with autism. It is recognised that autism results in substantial life-long disability. Severe emotional and behavioural problems are likely to be a key factor in precluding adults with autism from work, independent living, social contact, and undermine their quality of life, thus increasing support needs. This project aims to address a major gap in our current knowledge - the association between severe emotional and behavioural problems in adults with autism and social outcomes. Identification of markers of adult outcomes aims to lead to an improved understanding of the pathways to better social outcomes, facilitating the development of specific interventions to provide much needed improvements in outcomes for adults with autism.Read moreRead less
Improving academic outcomes by moderating anxiety in children with autism. The project aims to investigate links between anxiety and academic enablers for children with autism. As a group, these children are currently achieving at lower rates than their peers, with implications for their future social and economic wellbeing. Effective interventions to improve educational outcomes are lacking. This project will investigate how anxiety, a commonly occurring condition in autism, impacts attitudes a ....Improving academic outcomes by moderating anxiety in children with autism. The project aims to investigate links between anxiety and academic enablers for children with autism. As a group, these children are currently achieving at lower rates than their peers, with implications for their future social and economic wellbeing. Effective interventions to improve educational outcomes are lacking. This project will investigate how anxiety, a commonly occurring condition in autism, impacts attitudes and behaviours that facilitate students’ participation in and ability to benefit from academic instruction in the classroom. Findings are intended to provide an evidence base for the development of an intervention suitable for use by service providers to increase academic achievement in children with autism.Read moreRead less
Learning from errors: examining the neural mechanisms underlying performance monitoring and adaptive behaviour. This project aims to contribute to current scientific thinking on how the brain mechanisms underlying error processing influence adaptive behaviour. Self-recognition of errors deteriorates in many clinical conditions and is a predictor of poor prognostic outcome. However, it remains unclear how such dysfunction leads to the failure to adapt behaviour.
Experimental and computational assessment of the mechanical, musculo-skeletal and neuromuscular contributions to rhythmic multi-joint arm movements. The human body is a complex mechanical system that is controlled by a vast neural network comprising many millions of connections. To date, realistic descriptions of the interactions between these neuro-mechanical features have proved elusive. This project seeks to develop a mathematical model that accurately describes the essential features of the ....Experimental and computational assessment of the mechanical, musculo-skeletal and neuromuscular contributions to rhythmic multi-joint arm movements. The human body is a complex mechanical system that is controlled by a vast neural network comprising many millions of connections. To date, realistic descriptions of the interactions between these neuro-mechanical features have proved elusive. This project seeks to develop a mathematical model that accurately describes the essential features of the control system for human movement, and yet is simple enough to inform the design of artificial devices to generate or assist movement. The knowledge derived should improve mechanical and neural prosthetic systems, and guide rehabilitation protocols. The work will ultimately provide a considerable benefit to the community by reducing the social cost of a range of movement disorders.Read moreRead less
An inverse control approach to resolving the neural basis of spatial and muscular dependencies in coordinated multi-limb movements. Each year 48,000 Australians suffer from stroke with many survivors left with problems that limit limb function. With reduced duration of hospital care, the opportunities for retraining in the period immediate following stroke are rapidly diminishing. Effective and efficient strategies of rehabilitation that will maximise the level of recovery following stroke will ....An inverse control approach to resolving the neural basis of spatial and muscular dependencies in coordinated multi-limb movements. Each year 48,000 Australians suffer from stroke with many survivors left with problems that limit limb function. With reduced duration of hospital care, the opportunities for retraining in the period immediate following stroke are rapidly diminishing. Effective and efficient strategies of rehabilitation that will maximise the level of recovery following stroke will result in benefits expressed in terms of enhanced quality of life and functional life-span, as well as significantly reduced costs of health care. In understanding the fundamental principles underlying the stability and adaptability of movement coordination, this research is likely to make a significant contribution to the design of programs for movement rehabilitation.Read moreRead less
Cortical Mechanisms Mediating Bilateral Interactions Between the Upper Limbs. Each year 40,000 Australians suffer from stroke with many survivors left with problems that limit limb function.

Spatio-Temporal Precision of Interceptive Action. Interceptive actions like hitting a moving target require precise, accurate positioning and timing. This project aims to empirically document how spatial and temporal constraints affect performance of interceptions and to quantify the speed-accuracy trade-off for interceptions. The speed-accuracy trade-off for movements aimed at stationary targets has been extensively documented - slower movements are more accurate.

This project aims to empirically document how spatial and temporal constraints affect performance of interceptions and to quantify the speed-accuracy trade-off for interceptions. The speed-accuracy trade-off for movements aimed at stationary targets has been extensively documented - slower movements are more accurate. There has been no corresponding documentation for interception. This project will fill the gap and provide a rich data set for developing an understanding of interception through modeling work. An understanding of the factors governing interception has potential applications in road safety, sports and neurological rehabilitation.Read moreRead less
Left to right is front to back: attentional distortions in near and far space for healthy and clinical populations. We are investigating a perceptual bias that makes people think objects right in front of them are actually slightly to the right but objects far away are slightly to the left. This project will help understand why this happens, to help reduce traffic collisions and help people with brain damage that causes similar perceptual biases.
