It's only human: Understanding why errors occur in skilled behaviour. There is evidence that error plays a major role in the causes of workplace injury and errors in skilled behaviour are the most common type of error leading to occupational accidents. It is likely that skill-based error is also important in causing fatal and severe injury in other settings. If we want to reduce or prevent injury, tackling the causes of error, and especially skill-based error, must be a prime target. By reduci ....It's only human: Understanding why errors occur in skilled behaviour. There is evidence that error plays a major role in the causes of workplace injury and errors in skilled behaviour are the most common type of error leading to occupational accidents. It is likely that skill-based error is also important in causing fatal and severe injury in other settings. If we want to reduce or prevent injury, tackling the causes of error, and especially skill-based error, must be a prime target. By reducing skill-based error in the workplace, current estimates suggest that loss of life would be reduced by about 200 cases per year and annual direct and indirect costs to the community by $484 million. Similar benefits are likely to emanate from reducing skill-based error in other settings.Read moreRead less
Enhancing employee safety in response to workplace violence. International and national trends indicate that workplace violence is a significant growing problem. Poorly managed, victims can suffer physical and psychological trauma, and employers risk increases in workers compensation claims, insurance premiums, employee turnover, sick leave and low morale. There is a dearth of research into the effectiveness of training employees to predict, control and defuse aggressive incidents, yet this is a ....Enhancing employee safety in response to workplace violence. International and national trends indicate that workplace violence is a significant growing problem. Poorly managed, victims can suffer physical and psychological trauma, and employers risk increases in workers compensation claims, insurance premiums, employee turnover, sick leave and low morale. There is a dearth of research into the effectiveness of training employees to predict, control and defuse aggressive incidents, yet this is a significant priority for many industries. This project will develop and evaluate a new best practice aggression minimisation training program with 200 mental health employees by an RCT assessing gains in safety, knowledge, skills and confidence in managing violence.Read moreRead less
Assessment of Executive Function in Children and Adults. This project aims to develop tests for executive function that are better grounded in the theory of cognitive processes, have sound measurement properties, and are more efficient, than existing measures. Executive functions entail planning, self-evaluation and adaptation to novel situations. Executive function deficits are found in children and adults who have suffered injury to the frontal regions of the brain, in some ageing adults, and ....Assessment of Executive Function in Children and Adults. This project aims to develop tests for executive function that are better grounded in the theory of cognitive processes, have sound measurement properties, and are more efficient, than existing measures. Executive functions entail planning, self-evaluation and adaptation to novel situations. Executive function deficits are found in children and adults who have suffered injury to the frontal regions of the brain, in some ageing adults, and in certain clinical groups such as autistics. Ability to cope with complexity is a factor in executive functioning, and this will be assessed utilising a new approach to analysis of cognitive complexity.Read moreRead less
Hazard Perception and Cognitive Ageing in Older Drivers: Investigation and Development. Older road users have high fatal crash rates that cost the Australian economy $500 million each year. However, driving cessation is associated with depression and reduced social participation among older adults. The present study will benefit older road users and the wider community by identifying which traffic hazards pose the greatest difficulty for older drivers and providing information that may lead to a ....Hazard Perception and Cognitive Ageing in Older Drivers: Investigation and Development. Older road users have high fatal crash rates that cost the Australian economy $500 million each year. However, driving cessation is associated with depression and reduced social participation among older adults. The present study will benefit older road users and the wider community by identifying which traffic hazards pose the greatest difficulty for older drivers and providing information that may lead to adaptation of roads, and vehicles to reduce crash risk among older Australians. This will reduce injury and healthcare costs and allow older Australians to maintain higher levels of social participation.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.

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.

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
