Cortical regulation of attentional capture. The proposed experiments examine how brain mechanisms interact to determine whether a stimulus will capture our attention, distracting us from the task at hand. The experiments test competing theories of attentional control and have implications for clinical populations (for example, stroke) that have difficulty avoiding distraction.
A new training approach to address the novice driver problem. This project aims to develop a new approach to driver training. For the second consecutive year, road deaths in Australia have increased by 150 from 2014 to 2016. The increase in deaths was greatest for young drivers between the ages of 17-25 years, who remain over-represented in road deaths. The majority of these deaths occur in the first few months after licensing. This project expects to generate new knowledge, where the focus is o ....A new training approach to address the novice driver problem. This project aims to develop a new approach to driver training. For the second consecutive year, road deaths in Australia have increased by 150 from 2014 to 2016. The increase in deaths was greatest for young drivers between the ages of 17-25 years, who remain over-represented in road deaths. The majority of these deaths occur in the first few months after licensing. This project expects to generate new knowledge, where the focus is on developing young driver’s cognitive skills about speed choice through the provisions of a training program that focuses on feedback. The results will have the potential to be used by road authorities and driver training organisations to improve road safety.Read moreRead less
Overcoming language barriers in healthcare: towards safe and effective communication when patients or clinicians use a second language. An international team of scholars will study language barriers in Australia's healthcare syste; arising from growing numbers of patients and clinicians not speaking English as their first language. The project's results will lay the foundation for future research and point to practical solutions.
Concepts and control in speech production. While humans produce speech fluently in the course of everyday conversation, comparatively little is understood about the underlying mental processes and brain mechanisms. The overall aim of this project is to investigate how the human brain conceives and controls speech output by using state-of-the-art neuroimaging and brain stimulation techniques. The research aims to contribute novel insights into a key human ability with particular relevance for spe ....Concepts and control in speech production. While humans produce speech fluently in the course of everyday conversation, comparatively little is understood about the underlying mental processes and brain mechanisms. The overall aim of this project is to investigate how the human brain conceives and controls speech output by using state-of-the-art neuroimaging and brain stimulation techniques. The research aims to contribute novel insights into a key human ability with particular relevance for speech disorders such as aphasia, while the methods developed for brain stimulation during imaging of speech production aim to expand Australia's capability and technical innovation in the cognitive neuroscience of language.Read moreRead less
Control of language production and its neural substrates. The ability of humans to say the right word at the right time is a critical, complex and poorly understood function. This research will determine the brain circuits responsible for language production and how this process is affected in Parkinson's disease.
Risky Futures: Toward a Computational Process Model of Risky Inter-Temporal Choice. A lot is known about people’s preferences. People like their rewards now. Most would prefer $10 today than $20 in one month. Risk is also unattractive; a certain $10 is more attractive than a 50 per cent chance of receiving $25. Surprisingly, much less is known about the interaction between delay and risk. That is, relatively little is known about whether people prefer $10 now, or a 50 per cent chance of $50 in ....Risky Futures: Toward a Computational Process Model of Risky Inter-Temporal Choice. A lot is known about people’s preferences. People like their rewards now. Most would prefer $10 today than $20 in one month. Risk is also unattractive; a certain $10 is more attractive than a 50 per cent chance of receiving $25. Surprisingly, much less is known about the interaction between delay and risk. That is, relatively little is known about whether people prefer $10 now, or a 50 per cent chance of $50 in one month. This project will use a combination of experiments and cognitive modelling to examine all three types of choice. The outcome will be a novel computational model that will elucidate the complex interaction between delay and risk, thereby answering an enduring question in the literature: are risk and delay psychologically equivalent?Read moreRead less
Epigenetic mechanisms regulating sex differences in fear-related learning and memory. Anxiety disorders represent an enormous burden on society and are associated with premature aging and infertility in men and women. Evidence also indicates that parental anxiety affects child development. Given that fear-related learning has an important influence on emotional health which, in turn, affects lifestyle and the aging process, an understanding of the neural mechanisms mediating sex differences in ....Epigenetic mechanisms regulating sex differences in fear-related learning and memory. Anxiety disorders represent an enormous burden on society and are associated with premature aging and infertility in men and women. Evidence also indicates that parental anxiety affects child development. Given that fear-related learning has an important influence on emotional health which, in turn, affects lifestyle and the aging process, an understanding of the neural mechanisms mediating sex differences in fear learning will enhance our ability to develop better therapeutic approaches for treating anxiety and preventing relapse, potentially through a gender-specific approach. The studies outlined in this proposal will have implications for promoting and maintaining good health.Read moreRead less
Combining modal logics for dynamic and multi-agent systems. Modern computer software systems are required to operate in complex dynamic environments and to handle functioning of highly sensitive (security and safety-critical) organizations in government and commerce. Typical applications include air-traffic control systems, telecommunication networks, and banking systems. To ensure robustness, computationally predictable behaviour and trustworthiness of these systems, their designs and implement ....Combining modal logics for dynamic and multi-agent systems. Modern computer software systems are required to operate in complex dynamic environments and to handle functioning of highly sensitive (security and safety-critical) organizations in government and commerce. Typical applications include air-traffic control systems, telecommunication networks, and banking systems. To ensure robustness, computationally predictable behaviour and trustworthiness of these systems, their designs and implementations must be formally well grounded. This is an important but difficult challenge. This project will systematically develop a framework by combining modal-logics to adequately capture and reason about temporal, epistemic and social aspects of dynamic and multi-agent systems. The combined logics would be evaluated on practical applications.

Cognitive models of decision making in clinical populations. This cognitive science project aims to develop new methods for mathematical modelling of decision making, and to apply these methods to study decision making in people with problem drug use. Precise measures of the thought processes underlying decision making in drug users will help to direct efforts to prevent and treat drug problems.
A process model of visual working memory. This project aims to develop a process model of encoding of items into memory. Working memory is central to almost all cognitive functions, but little is known about short-term memory for visual information. Progress in this area is slow because of a focus on models that do not specify the processes underlying memory, and no model explains the processes that would limit the number of items the memory can hold to four. A process model is expected to addre ....A process model of visual working memory. This project aims to develop a process model of encoding of items into memory.
