Single and dual process models of recognition memory: Reconciliation of behavioural, electrophysiological, and neuroimaging data. Advanced brain scanning technologies are increasingly used to study human memory. As well as being important for our basic understanding of memory, they also tell us how memory is affected by normal development, ageing, disease, and injury. Unfortunately, because these technologies are so new, a gap has opened up between our psychological understanding of memory and t ....Single and dual process models of recognition memory: Reconciliation of behavioural, electrophysiological, and neuroimaging data. Advanced brain scanning technologies are increasingly used to study human memory. As well as being important for our basic understanding of memory, they also tell us how memory is affected by normal development, ageing, disease, and injury. Unfortunately, because these technologies are so new, a gap has opened up between our psychological understanding of memory and the physiological events measured by the scanning technologies. This has created a problem for how we should interpret the results that are found. The present project aims to close this gap by applying new research methodologies and theoretical insights based on our previous research.Read moreRead less
How we recognise the orientation of objects: a combined neurophyschological / eye movement study. Neurophyschological evidence suggests that different visual attributes of objects (e.g. shape vs orientation in space) are processed by independent brain systems. This project aims to investigate this issue systematically, using both neurological patients and normal volunteers. By using sensitive experimental measures, including detailed analyses of subject's eye movements while they view objects, ....How we recognise the orientation of objects: a combined neurophyschological / eye movement study. Neurophyschological evidence suggests that different visual attributes of objects (e.g. shape vs orientation in space) are processed by independent brain systems. This project aims to investigate this issue systematically, using both neurological patients and normal volunteers. By using sensitive experimental measures, including detailed analyses of subject's eye movements while they view objects, this research will provide valuable insights into how the visual system gathers and encodes information about different object attributes.Read moreRead less
Evidence-based improvement of statistical inference practices in psychology and other disciplines. The commonest ways that many researchers currently draw conclusions from their data have been shown to be inefficient, and often used incorrectly. This project will develop new, better statistical representations and software tools for data analysis. It will evaluate and demonstrate the effectiveness of these. Wide adoption of these techniques and tools will enhance the international reputation ....Evidence-based improvement of statistical inference practices in psychology and other disciplines. The commonest ways that many researchers currently draw conclusions from their data have been shown to be inefficient, and often used incorrectly. This project will develop new, better statistical representations and software tools for data analysis. It will evaluate and demonstrate the effectiveness of these. Wide adoption of these techniques and tools will enhance the international reputation and competitiveness of Australian psychological science. Adoption by Australian researchers across the social and behavioural sciences, and in other disciplines including medicine, economics and ecology, will improve the efficiency and effectiveness of Australian research, with consequential wide-ranging benefits to the Australian community.Read moreRead less
Do director board appointments predict whether CEO pay is in line with company performance? Increasing pay differences between CEOs and the average working Australian have resulted in a less equitable and economically divided society. This issue has reached a critical point as taxpayer money is now needed to fund stimulus packages and finance companies facing insolvency while CEO pay on average has remained unchanged or increased. This inequity has the potential to cause social and political ins ....Do director board appointments predict whether CEO pay is in line with company performance? Increasing pay differences between CEOs and the average working Australian have resulted in a less equitable and economically divided society. This issue has reached a critical point as taxpayer money is now needed to fund stimulus packages and finance companies facing insolvency while CEO pay on average has remained unchanged or increased. This inequity has the potential to cause social and political instability. This research will provide much needed knowledge of how to address this issue including pay benchmarks, knowledge derived from international practice, corporate governance indices as well as understanding of how widespread pay norms have developed.Read moreRead less
The structure and dynamics of social contact for human disease transmission models. The methodological advances of this project will enable new insights in important social research. They will not only add significantly to national capacity in the modelling of complex social systems but they will also yield practical scientific outcomes in a significant policy domain in Australia and overseas. In Australia, response to diseases such as HIV, HCV and TB need new approaches, and the threat of pan ....The structure and dynamics of social contact for human disease transmission models.

In Australia, response to diseases such as HIV, HCV and TB need new approaches, and the threat of pandemic influenza is significant. Read moreRead less
Categorization and Working Memory: Bridging two Pillars of Cognition. Categorization is a fundamental cognitive skill that underlies much expert behavior, including medical diagnosis. A given task often gives rise to widely divergent strategies across individuals, and flawed strategies have been implicated in prediction errors of experts (e.g., bush fire fighters). This project seeks to identify the underlying variables that determine an individual's strategy acquisition by relating working memo ....Categorization and Working Memory: Bridging two Pillars of Cognition. Categorization is a fundamental cognitive skill that underlies much expert behavior, including medical diagnosis. A given task often gives rise to widely divergent strategies across individuals, and flawed strategies have been implicated in prediction errors of experts (e.g., bush fire fighters). This project seeks to identify the underlying variables that determine an individual's strategy acquisition by relating working memory performance to categorization. Working memory is a core cognitive construct that is quite well understood, but its relationship to category learning has so far remained unexplored. Being able to predict the development of categorization strategies can help maximize expert performance.Read moreRead less
A new kind of dynamics for psychology. In order to remain efficient in real-world decisions, people must dynamically monitor and adjust their cognitive processes. This project aims to develop innovative methods and analyses for dynamics in experimental psychology, using standard paradigms in which task parameters are dynamically manipulated. The development of models of dynamic behaviour will advance the science of psychology and serve as a practical measurement tool for individuals.
Are two processes one too many? An investigation of the viability of the dual-process model of recognition memory. Memory is the glue that holds together our lives and personal identities. While psychologists are developing better and more sophisticated accounts of how it works, many deep questions remain. The present research examines some of these questions in relation to how memory can be decomposed into its component processes and how we are to understand these processes. An appropriate unde ....Are two processes one too many? An investigation of the viability of the dual-process model of recognition memory. Memory is the glue that holds together our lives and personal identities. While psychologists are developing better and more sophisticated accounts of how it works, many deep questions remain. The present research examines some of these questions in relation to how memory can be decomposed into its component processes and how we are to understand these processes. An appropriate understanding of these questions is vital to the development of interventions (both psychological and pharmacological) designed to halt or even reverse memory decline associated with normal aging and age-associated brain disease (such as Alzheimer disease).Read moreRead less
Do intentions predict health-related behaviours? Implications of method bias for the design of public health promotion programs. Each year millions of dollars are expended on public health initiatives to encourage healthier lifestyle behaviours, such as diet, exercise, smoking and sun-protection. This project will investigate the cumulative empirical evidence to evaluate the validity of the theories that purport to explain why people behave the way they do.
Exploration, Generalisation and the Development of Learning Traps. This project addresses three fundamental questions about human decision-making; 1) how does exploratory choice lead to “learning traps”, persistent patterns of poor decision-making that cause us to miss rewards and experience losses? 2) how does susceptibility to traps change with age? 3) what strategies prevent traps or facilitate escape? The project will advance our understanding of the cognitive processes underlying adult and ....Exploration, Generalisation and the Development of Learning Traps. This project addresses three fundamental questions about human decision-making; 1) how does exploratory choice lead to “learning traps”, persistent patterns of poor decision-making that cause us to miss rewards and experience losses? 2) how does susceptibility to traps change with age? 3) what strategies prevent traps or facilitate escape? The project will advance our understanding of the cognitive processes underlying adult and child decision-making, using innovative experimental paradigms and computational modeling. Expected outcomes include a novel computational model that explains developmental change in trap formation. The results will guide strategies for improved decision-making in educational, financial, and social settings.Read moreRead less
