Learning from our mistakes: How and when complex decisions fail. The project aims to develop a novel mathematical framework, augmented by simulations and a set of experiments, to study when and how people commit errors. The modern environment bombards us with signals, such as radio and television advertisements as we sit at home or warning lights and car honks as we cross the road. Despite years of psychological research, it is not entirely clear how efficiently people cope with increasing amoun ....Learning from our mistakes: How and when complex decisions fail. The project aims to develop a novel mathematical framework, augmented by simulations and a set of experiments, to study when and how people commit errors. The modern environment bombards us with signals, such as radio and television advertisements as we sit at home or warning lights and car honks as we cross the road. Despite years of psychological research, it is not entirely clear how efficiently people cope with increasing amounts of information nor is it clear whether they process multiple signals simultaneously (in parallel) or one after the other (serial). The project offers new measures, based on the rate and pattern of error responses, to supplement the commonly used response times. The combination of a theoretical framework, based on mathematical and computational work, with empirical data to test the models, may deliver a better understanding of human performance and its limitations.Read moreRead less
Choice models for learning and memory. Life is filled with familiar choices that often require quick decisions about objects in the environment and the contents of memory. This project examines how we learn to make rapid and accurate choices and how we quickly asses the level of confidence we have in recognition decisions based on our memories.
A Scalable Theory of Behavior Composition for Practical Engineering Models of Human Performance. 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 critica ....A Scalable Theory of Behavior Composition for Practical Engineering Models of Human Performance. 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
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
Can attentional re-training reduce food cravings and consumption? This project aims to determine the impact of a procedure involving the re-training of attention to food cues on food cravings and food intake. Results will advance our understanding of food cravings and contribute to interventions aimed at curbing unwanted cravings and (over) consumption.

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
