There are countless uses for technology that records visual behaviour; these include reading and cognitive psychology research, ergonomic design, web site usability testing, and evaluation of visual information (for example advertising or in ?virtual? environments). As such, recording eye movements has applications in pure and applied research, and in teaching demonstrations for students.
This application proposes to purchase eye movement recording equipment to form a dedicated and truly collaborative facility to measure visual behaviour. The facility would be unique in Australia and would be invaluable to both further understand visual/cognitive processes and how individuals interact with their environments.Read moreRead less

Minimizing human error and maximizing human performance is a major design goal in safety critical systems. The development of methods for affordable human performance modeling has widespread applicability for evaluating user-system interfaces. The compositional method explored here has been shown to make accurate predictions reduce model development time by an order of magnitude. Large safety critical applications, such as military or air traffic control systems, would benefit greatly. The proposed work tests whether the compositional methods will scale to more complex domains. The work will be coordinated with Australian industry, academia, and government research efforts.Read moreRead less
Determinants and consequences of conscious visual awareness. Usually salient images can disappear from awareness without corresponding stimulus changes. This project is based on an innovative account linking such disappearances to a functional adaptation which facilitates vision in cluttered environments. Project completion will expand Australia's knowledge base, forge links between junior and senior Australian based investigators and provide excellent training opportunities. Publication of rese ....Determinants and consequences of conscious visual awareness. Usually salient images can disappear from awareness without corresponding stimulus changes. This project is based on an innovative account linking such disappearances to a functional adaptation which facilitates vision in cluttered environments. Project completion will expand Australia's knowledge base, forge links between junior and senior Australian based investigators and provide excellent training opportunities. Publication of research in top-ranking international journals will further promote Australian science abroad. Ultimately, this research will have implications for the design and implementation of artificial visual systems, which must overcome many of the same dilemmas faced by the human visual system in cluttered environments.Read moreRead less
Human Time Perception. Most human tasks require timing on a scale of tens to hundreds of milliseconds. We must judge time to produce and comprehend speech, to move about and interact with our dynamic environment, to determine causality and decode information from sensory receptors. However, the neural bases of time perception are largely unknown. This project will explore temporal phenomena to determine how and where durations, temporal order and coincidence are encoded in the human brain. Proje ....Human Time Perception.

However, the neural bases of time perception are largely unknown. This project will explore temporal phenomena to determine how and where durations, temporal order and coincidence are encoded in the human brain. Project results will provide new insight into the mechanisms of time perception, with implications for disorders associated with impaired time perception, such as autism, dyslexia and schizophrenia.Read moreRead less
Why does time seem to drag and fly? This project aims to investigate varying perceptions about the passage of time. It is unclear if these variations reflect functional adaptations that allow fast information processing in the face of disaster or if such sensations are inferred after the events in question. Nor is it clear if such experiences are similar across individuals. The project aims to answer these questions, with long-term potential to inform artificial intelligence systems that rely on ....Why does time seem to drag and fly? This project aims to investigate varying perceptions about the passage of time.

Nor is it clear if such experiences are similar across individuals. The project aims to answer these questions, with long-term potential to inform artificial intelligence systems that rely on temporal sensitivity. The project also has potential to provide insights into conditions associated with impaired time perception-place roles.Read moreRead less
Insights from brain imaging to study the neural basis of cognition. This project aims to address a major challenge - the need for a better understanding of the basis for human cognition. Humans have a unique capacity for diverse, complex, thought and behaviour. To achieve this our brains need to rapidly and flexibly reconfigure, directing attention to different aspects of the world moment-to-moment as we think and act. The project will combine innovative analysis methods with state-of-the-art n ....Insights from brain imaging to study the neural basis of cognition. This project aims to address a major challenge - the need for a better understanding of the basis for human cognition. Humans have a unique capacity for diverse, complex, thought and behaviour. To achieve this our brains need to rapidly and flexibly reconfigure, directing attention to different aspects of the world moment-to-moment as we think and act. The project will combine innovative analysis methods with state-of-the-art neuroimaging and brain stimulation to understand how key brain regions drive this process. Insights from this project will link brain activation to behaviour, improve insights from brain imaging, and contribute a better understanding of the neural basis of cognition. Such insights can ultimately benefit the development of evidence based approaches to key areas of public concern such as health and education.Read moreRead less
Distorted Time Perceptions: Altered neural coding or decisional criteria? Human time perception is subject to systematic distortions. For instance, prolonged exposure to a movie wherein sounds lead the visual footage can result in this timing relationship seeming to be synchronous when it did not previously. As yet, it is unclear if such effects reflect altered neural processing times (in this example, visual analyses could be sped, or auditory analyses slowed), or if neural processing times are ....Distorted Time Perceptions: Altered neural coding or decisional criteria? Human time perception is subject to systematic distortions. For instance, prolonged exposure to a movie wherein sounds lead the visual footage can result in this timing relationship seeming to be synchronous when it did not previously. As yet, it is unclear if such effects reflect altered neural processing times (in this example, visual analyses could be sped, or auditory analyses slowed), or if neural processing times are unchanged, with people simply altering the decisions they make about sensory inputs. This project will determine which type of scenario is responsible for a number of distortions of human time perception. Read moreRead less
Human Vision: Predicting the present? Suppressing the past? When dealing with moving objects, how does the human brain cope with lags between exposure to retinal images depicting physical events and consequent activity in cortex? Obviously motor planning plays a role, with people reaching toward predicted locations when intercepting moving objects, but what, if any, compensation for informational delays is provided by perception? This project will explore situations wherein moving objects are er ....Human Vision: Predicting the present? Suppressing the past? When dealing with moving objects, how does the human brain cope with lags between exposure to retinal images depicting physical events and consequent activity in cortex? Obviously motor planning plays a role, with people reaching toward predicted locations when intercepting moving objects, but what, if any, compensation for informational delays is provided by perception? This project will explore situations wherein moving objects are erroneously localised and seem deformed, in order to determine if these are indicative of perception helping to compensate for informational lags. Project results will have substantial theoretical significance, pertaining to the nature of perception and conscious visual awareness.Read moreRead less

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

This project aims to provide greater understanding of the neural mechanisms by which initiation of motor responses can be improved by unexpected auditory stimulation. Initiating motor actions appears natural and effortless, but is underpinned by complex neural mechanisms that are not well understood. Using novel brain stimulation techniques, the project aims to assess the potential for properly timed strong sensory stimulation during movement preparation to induce neural plasticity and motor learning. This knowledge would have important implications across a number of fields, including neuroscience, sports science, and applied ergonomics.Read moreRead less
