Auditory spatial perception during head movements. Orienting to stimuli frequently involves eye and head movements. This improves localisation, yet brings attendant problems (eg, blurring). These problems are well understood in vision, but not in audition, despite evidence for common neural mechanisms. We will examine auditory (and visual) localisation during head movements, showing head movements produce auditory suppression and spatial distortions (analogous to visual saccadic effects).

This improves localisation, yet brings attendant problems (eg, blurring). These problems are well understood in vision, but not in audition, despite evidence for common neural mechanisms. We will examine auditory (and visual) localisation during head movements, showing head movements produce auditory suppression and spatial distortions (analogous to visual saccadic effects). This will demonstrate the malleability of auditory spatial perception and the impoverished sensitivity of audition during head and self-motion. Knowledge of these distortions will inform applications such as cockpit design, where orienting to auditory signals is common, and other human/computer interfaces.

Lexical retrieval and reading comprehension: Binding perceptual, lexical and conceptual information in on-line reading. Reading is a complex process that involves integrating sensory information extracted from text with stored memories about word meanings, syntactic structures and general knowledge. Most reading research has focused on the processing of isolated words, but normal reading requires integration processes that are not necessary to recognise single words. This research uses tasks req ....Lexical retrieval and reading comprehension: Binding perceptual, lexical and conceptual information in on-line reading. Reading is a complex process that involves integrating sensory information extracted from text with stored memories about word meanings, syntactic structures and general knowledge. Most reading research has focused on the processing of isolated words, but normal reading requires integration processes that are not necessary to recognise single words. This research uses tasks requiring sentence comprehension and measures of eye movements during reading to investigate how readers retrieve and combine information while reading to comprehend text. It will contribute to developing more comprehensive theories of normal reading that can inform methods of teaching reading and contribute to refinement of text recognition systems.Read moreRead less

BREAKING THE JUVENILE CRIME CYCLE: REHABILITATING HIGH RISK YOUNG OFFENDERS. Effective rehabilitation of young offenders is an urgent social need. Using mathematical modelling of longitudinal population data, we will identify predictors of recidivism, desistance, health risk behaviours, and/or progression to injecting drug use. Collaborating with NSW Department of Juvenile Justice and NSW Corrections Health Service, we will develop and trial community-based multisystemic interventions using the ....BREAKING THE JUVENILE CRIME CYCLE: REHABILITATING HIGH RISK YOUNG OFFENDERS. Effective rehabilitation of young offenders is an urgent social need. Using mathematical modelling of longitudinal population data, we will identify predictors of recidivism, desistance, health risk behaviours, and/or progression to injecting drug use. Collaborating with NSW Department of Juvenile Justice and NSW Corrections Health Service, we will develop and trial community-based multisystemic interventions using the transtheoretical model to reduce re-offending. This project will advance theoretical understanding of juvenile crime, its health and substance abuse patterns, and offence trajectories, thereby facilitating effective policies and practices to reduce recidivism, improve health and create prosocial alternatives for young Australians at risk of a criminal career.Read moreRead less
Developing vehicle-based advanced warning countermeasures for driver fatigue. Driver fatigue is a major problem in Australia in terms of health, road safety and economic impact. Countermeasures to combat the influence of driver fatigue have been limited to public campaign strategies like resting every 2 hours. There has been little robust research on developing on-road countermeasures that could warn the driver of their fatigue status. This proposed project involves a collaboration with Compumed ....Developing vehicle-based advanced warning countermeasures for driver fatigue. Driver fatigue is a major problem in Australia in terms of health, road safety and economic impact. Countermeasures to combat the influence of driver fatigue have been limited to public campaign strategies like resting every 2 hours. There has been little robust research on developing on-road countermeasures that could warn the driver of their fatigue status. This proposed project involves a collaboration with Compumedics Ltd, a leading medical device company, to conduct sophisticated research into developing an EEG and wheel behaviour fatigue countermeausure. We will further explore EEG and wheel behaviour patterns associated with fatigue, investigate noise control strategies, and conduct laboratory and on road field trials of the fatigue monitor. If this device is able to assess fatigue reliably and warn drivers in sufficient time to avert accidents, then substantial economic and social benefits will occur.Read moreRead less
Filters reveal what flicker conceals: temporal processing in the human visual system. I have recently discovered a new form of camouflage using 10Hz luminance flicker. This project will quantify this effect and examine the extent to which it generalises across colour and spatial dimensions and to video sequences depicting natural scenes. This information is expected to provide foundational information to technologies relating to national security that rely on visual concealment.

This project will quantify this effect and examine the extent to which it generalises across colour and spatial dimensions and to video sequences depicting natural scenes. This information is expected to provide foundational information to technologies relating to national security that rely on visual concealment. This research will examine the extent to which filtering out these camouflaging frequencies enhances our sensitivity to low temporal frequency information. This decamouflaging aspect of my research is expected to improve the clarity of digital video-based technologies including ultrasound, educational, info-tainment and defence applicationsRead moreRead less

This project aims to understand the conditions that cause humans to misperceive the shape and surface properties of real-world materials. Most natural materials are translucent to varying degrees, but little is known about how light is transported through them or how such materials are perceived or misperceived. This project will determine the conditions and causes responsible for the misperception of material properties and shape, and will offer practical information about what can be done to minimise such misperceptions. The outcomes of the project are expected to lead to new techniques for depicting and manipulating real-world translucent materials in computer graphics, virtual reality, and gaming industries.Read moreRead less
