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 research wi ....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 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
The initiation and control of action in motor vehicle driving. Every time we pull up to a traffic light or overtake another vehicle our brain is making a whole series of critical decisions about when and how to carry out the manoeuvre accurately and safely. This project seeks to better understand the processes involved. Using the latest, high fidelity GPS and accelerometer technology, highly accurate measurements of driver behaviour and vehicle dynamics will be made in a real vehicle.

Every time we pull up to a traffic light or overtake another vehicle our brain is making a whole series of critical decisions about when and how to carry out the manoeuvre accurately and safely. This project seeks to better understand the processes involved. Using the latest, high fidelity GPS and accelerometer technology, highly accurate measurements of driver behaviour and vehicle dynamics will be made in a real vehicle. Understanding when and how we carry out these types of basic tasks will play a central role in future brake, suspension and steering system design; will help guide the specifications of road and road sign design; and will help motivate additions or alterations to current driver training programmes.Read moreRead less
The anatomy of a fatigue-related motor vehicle crash or near-crash. The anatomy of a fatigue-related motor vehicle crash or near-crash. This project aims to investigate the time course of multiple physiological and behavioural signals that lead to fall-asleep (on-road) driving events, to inform the next generation of driver state monitoring technologies. Falling asleep at the wheel remains a major cause of road crashes worldwide.

The anatomy of a fatigue-related motor vehicle crash or near-crash. This project aims to investigate the time course of multiple physiological and behavioural signals that lead to fall-asleep (on-road) driving events, to inform the next generation of driver state monitoring technologies. Falling asleep at the wheel remains a major cause of road crashes worldwide. Although technologies to monitor driver sleepiness are integral to the rapidly evolving autonomous vehicle industry, such technologies are limited because they measure the end-state of falling asleep, rather than the physiological and behavioural precursors, thus providing little opportunity for intervention. This project is expected to lead to new driver monitoring systems that reduce fall-asleep crashes.Read moreRead less
The Australian naturalistic driving study: innovation in road safety research and policy. A revolutionary new approach, the naturalistic driving study, will investigate what people actually do when they drive, in normal and safety-critical situations. It will provide Australia with answers to some intractable, high priority, road safety problems that cannot be answered using current methods, thereby saving hundreds of lives.

Unravelling Leadership Development: Evaluating outcomes, contrasting interventions, and exploring processes. This project investigates how leadership development interventions translate into effective outcomes for organizations. We compare how distinct interventions (transformational leadership vs. 360 degree feedback) and different modes of delivery (face-to-face vs. videoconferencing) lead to change in leader behavior. We investigate the cognitive/motivational mechanisms (e.g., self-efficacy, ....Unravelling Leadership Development: Evaluating outcomes, contrasting interventions, and exploring processes. This project investigates how leadership development interventions translate into effective outcomes for organizations. We compare how distinct interventions (transformational leadership vs. 360 degree feedback) and different modes of delivery (face-to-face vs. videoconferencing) lead to change in leader behavior. We investigate the cognitive/motivational mechanisms (e.g., self-efficacy, perspective-taking) by which these interventions affect leader behavior, as well as the multilevel processes by which change in leader behavior affects team performance and team well-being. The project will provide a more accurate assessment on the return of investment in leadership development, as well as guidance for enhancing the effectiveness of leadership development programs.

Drivers' Behavioural Responses to Traffic Signs. Traffic signs are ubiquitous in the road environment; research to improve their effectiveness can be very cost-effective in terms of safety improvements. Conducting traffic sign research on real roads has many difficulties, such as ethical considerations and lack of control. To overcome this, the research will be conducted in a driving simulator, in which the interaction between drivers and their equipment/environment will be studied. The aim of ....Drivers' Behavioural Responses to Traffic Signs.

Conducting traffic sign research on real roads has many difficulties, such as ethical considerations and lack of control. To overcome this, the research will be conducted in a driving simulator, in which the interaction between drivers and their equipment/environment will be studied. The aim of this project is to further understand drivers? behavioural responses to traffic signs, the expected outcome being to make the exchange of information between the driver and traffic sign as smooth and efficient as possible.Read moreRead less

An investigation of limb dynamics as a constraint on human motor learning. Everyday we use our limbs to interact with a variety of objects. These objects have various mechanical characteristics (dynamics), which require the human motor system to provide appropriate control. This project seeks to understand how the brain, in both normal and disease states, learns new limb dynamics as we interact with a novel mechanical environmental. Repetitive brain stimulation will be used to selectively block ....An investigation of limb dynamics as a constraint on human motor learning. Everyday we use our limbs to interact with a variety of objects. These objects have various mechanical characteristics (dynamics), which require the human motor system to provide appropriate control. This project seeks to understand how the brain, in both normal and disease states, learns new limb dynamics as we interact with a novel mechanical environmental. Repetitive brain stimulation will be used to selectively block the contribution of various cortical regions during the learning of a new motor skill and later, the recall of that skill. This will allow us to determine definitively which areas are critical to motor skill acquisition.Read moreRead less
Mechanisms of Recovery after Extinction of Conditioned Behaviour. Old habits die hard and may never die at all. My previous ARC-funded research has revealed that extinguished learning can be recovered rapidly and in unsuspected ways. This project is aimed at building a neural network to explain how old learning can recovered. In practical terms, rapid recovery has both benefits, e.g., our ability to regain old skills with brief refresher training, and costs, e.g., relapse after therapies for anx ....Mechanisms of Recovery after Extinction of Conditioned Behaviour. Old habits die hard and may never die at all. My previous ARC-funded research has revealed that extinguished learning can be recovered rapidly and in unsuspected ways. This project is aimed at building a neural network to explain how old learning can recovered. In practical terms, rapid recovery has both benefits, e.g., our ability to regain old skills with brief refresher training, and costs, e.g., relapse after therapies for anxiety disorders and substance abuse. In theoretical terms, understanding recovery in biological systems will inform research concerning both the neural basis of memory and the design of robots.Read moreRead less
