Perceiving and tracking moving objects. Processing and tracking moving objects poses challenges for human perception. To succeed, visual processing must accumulate analyses of the object from its different positions. Perceptual experiments will reveal human limits and yield insights into the underlying mechanisms, providing a basis for understanding object tracking in tasks like driving.
Neuronal activity underlying efficient sensory processing. This project aims to study how neuronal activity in the sensory cortex efficiently represents the external world. Operating with a finite quantity of attentional resources, the brain needs to prioritise processing to provide important information about a situation. This project combines neurophysiology, behavioural and computational sciences to study attention mechanisms in rodents. This multidisciplinary project aims to develop a novel ....Neuronal activity underlying efficient sensory processing.

Operating with a finite quantity of attentional resources, the brain needs to prioritise processing to provide important information about a situation. This project combines neurophysiology, behavioural and computational sciences to study attention mechanisms in rodents. This multidisciplinary project aims to develop a novel paradigm for studying sensory prioritisation in rodents as a model organism.Read moreRead less
The causes and consequences of attentional rescaling. This project aims to investigate the mechanisms that underlie people’s capacity to rescale the focus of their visual attention. Such rescalings are important because they are linked with people’s capacity to perform specific tasks. Using an innovative approach within cognitive psychology that integrates individual differences, experimental, and training frameworks, this project expects to generate new theoretical knowledge about attentional ....The causes and consequences of attentional rescaling. This project aims to investigate the mechanisms that underlie people’s capacity to rescale the focus of their visual attention. Such rescalings are important because they are linked with people’s capacity to perform specific tasks. Using an innovative approach within cognitive psychology that integrates individual differences, experimental, and training frameworks, this project expects to generate new theoretical knowledge about attentional re-scaling and its possible improvement. The expected outcomes include selection and training programs for specific contexts such as training athletes and flight attendants. Economic benefits can be expected through the identification of those who will benefit most from training (reducing waste) and developing cost-effective forms of training which improve task performance.Read moreRead less
Form and motion interactions in human motion perception. Vision works efficiently to detect the motion of both ourselves and other objects by combining motion and pattern information. This project will determine how the visual system achieves this and also create a detailed model that will be directly applicable to areas ranging from clinical neuropsychology to the analysis and design of visual displays.
Predicting the diagnostic performance of individuals and organisations. Predicting the diagnostic performance of individuals and organisations. This project aims to address diagnostic error in advanced technology systems, by providing a mechanism to assess and improve individual diagnosticians’ performance. Organisations that rely on their employees’ diagnostic skills rarely assess them once the operators become qualified, so there is no basis for interventions that might prevent diagnostic erro ....Predicting the diagnostic performance of individuals and organisations. Predicting the diagnostic performance of individuals and organisations. This project aims to address diagnostic error in advanced technology systems, by providing a mechanism to assess and improve individual diagnosticians’ performance. Organisations that rely on their employees’ diagnostic skills rarely assess them once the operators become qualified, so there is no basis for interventions that might prevent diagnostic errors affecting thousands. This research tests a new method of assessing diagnostic skills based on how skilled operators respond to cues. This project will test how employees’ diagnostic skills change and whether this change corresponds to measures of organisational performance. This research is expected to provide organisations with a tool to pre-empt diagnostic errors that could minimise costs to the economy.Read moreRead less
Neuronal and behavioural correlates of sensory adaptation. Sensory systems adapt to the statistics of their environment, and the consequences of this adaptation are evident in neuronal activity and in animal’s behaviour. This project will employ a novel paradigm to characterise how adaptation changes the response properties of individual sensory neurons to improve efficiency of information transmission.
Perceptual and psychosocial factors associated with individual differences in face identity and face expression processing. What makes one person better or worse than another at recognising faces, or the emotions displayed in those faces? This project examines which aspects of visual perception contribute to these abilities, and their associations with problems such as debilitating social anxiety and young children's anti-social behaviour.
Attention and hazard perception while driving: how experts see the scene. All drivers have 'drifted-off' or failed to see something that was clearly in view, yet trained expert drivers appear to rarely experience this. This project aims to understand in both 'normal' drivers and expert drivers, attentional mechanisms that control distraction and the perception of hazards, which is critical to road safety and young driver training.

Summary
Driving as a model for investigating and improving visual search abilities. Visual search is a fundamental skill that is required in several aspects of everyday life. Driving represents an example of high-stakes search: we must constantly scan the environment in order to identify both potential hazards and informational cues, such as traffic lights and signs. While most drivers are experienced (they have been driving for years) they are not experts (they have no special training or skills); this ....Driving as a model for investigating and improving visual search abilities. Visual search is a fundamental skill that is required in several aspects of everyday life. Driving represents an example of high-stakes search: we must constantly scan the environment in order to identify both potential hazards and informational cues, such as traffic lights and signs. While most drivers are experienced (they have been driving for years) they are not experts (they have no special training or skills); this lack of expertise potentially affects search accuracy and, in turn, road safety. This project aims to use and extend existing models of visual search performance in order to explore factors that influence drivers' visual search abilities, and to identify strategies for reducing these perceptual failures and, in turn, road crashes.Read moreRead less
Protecting the Australian passport by developing face recognition training programs that effectively integrate human operators and machine systems. The security of the Australian passport is vital to the fight against crime and terrorism. This project will help detect identity fraud in passport applications by developing training programs drawing on the psychology of face processing to optimally combine human decision making with machine face recognition systems to maximise fraud detection.
