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.
Improving external validity of stated choice experiments. This project aims to deliver more accurate estimates of choice behaviour by reducing biases due to choice task complexity in surveys as well as design artefacts. Extracting 'true' preferences is challenging, not only due to possible hypothetical bias, but also due to increasingly complex choice tasks and the existence of design artefacts. This project will investigate the latter two in the context of marketing, transport, health, and envi ....Improving external validity of stated choice experiments. This project aims to deliver more accurate estimates of choice behaviour by reducing biases due to choice task complexity in surveys as well as design artefacts. Extracting 'true' preferences is challenging, not only due to possible hypothetical bias, but also due to increasingly complex choice tasks and the existence of design artefacts. This project will investigate the latter two in the context of marketing, transport, health, and environmental economics, and proposes new methodologies to extract preferences that more closely reflect true behaviour in real markets.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.
Molecular force sensing mechanisms of PIEZO channels. The aim of this project is to characterise the gating mechanism of Piezo mechanosensitive ion channels recently identified in animals and humans. Mechanotransduction is ancient, as indicated by the presence of mechanosensitive channels in bacteria where these channels are activated by the bilayer mechanism according to the force-from-lipids paradigm possibly applicable to gating of the Piezo channels as well. Piezo channels play a crucial rol ....Molecular force sensing mechanisms of PIEZO channels. The aim of this project is to characterise the gating mechanism of Piezo mechanosensitive ion channels recently identified in animals and humans. Mechanotransduction is ancient, as indicated by the presence of mechanosensitive channels in bacteria where these channels are activated by the bilayer mechanism according to the force-from-lipids paradigm possibly applicable to gating of the Piezo channels as well. Piezo channels play a crucial role in senses of touch and pain, and mutations in Piezo1 have been shown to cause Xerocytosis – a hereditary genetic disorder manifested in haemolytic anemia. This project aims to help answer fundamental questions in mechanotransduction in vertebrates.Read moreRead less
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
The value of time during decisions. This project aims to investigate how people value time during decision making. Using an innovative combination of carefully designed experiments and state-of-the-art mathematical cognitive models, this project expects to generate new knowledge regarding how efficiently people allocate time when making decisions, the factors that allow people to perform optimally and those that lead to suboptimal performance. The anticipated outcome of the project is a new fram ....The value of time during decisions. This project aims to investigate how people value time during decision making. Using an innovative combination of carefully designed experiments and state-of-the-art mathematical cognitive models, this project expects to generate new knowledge regarding how efficiently people allocate time when making decisions, the factors that allow people to perform optimally and those that lead to suboptimal performance. The anticipated outcome of the project is a new framework for understanding the optimality of human decision making. This outcome has the potential benefit of providing insight into decision mechanisms across a range of contexts, particularly ageing and models of applied decision making.Read moreRead less
Poor Women and Lonely Men: Examining Gendered Social Inclusion and Connection in Australia. This project directly supports the national research priority goal of 'strengthening Australia's social and economic fabric' (as part of Promoting and Maintaining Good Health). Inclusive societies reap many benefits (economic, education, crime, health etc), and information revealed about relevant gendered patterns will help build social inclusion and connection in Australia by informing inclusive strategi ....Poor Women and Lonely Men: Examining Gendered Social Inclusion and Connection in Australia. This project directly supports the national research priority goal of 'strengthening Australia's social and economic fabric' (as part of Promoting and Maintaining Good Health). Inclusive societies reap many benefits (economic, education, crime, health etc), and information revealed about relevant gendered patterns will help build social inclusion and connection in Australia by informing inclusive strategies and policies. The project also supports the national research priority goal 'ageing well and productively', by informing policy-contexts of specific disadvantage, such as amongst those ageing alone. The project will also add to broader understandings about the links between social inclusion, connection and wellbeing.Read moreRead less
Harnessing Business Insights from Unstructured Customer Data. Resulting from customers’ widespread uptake of online channels to buy and communicate has been a surge in online reviews and social media posts. This textual information offers a viable alternative to surveys that Australian businesses currently conduct to obtain customer insights. However, these reviews are unstructured and require substantial pre-processing to extract underlying customer perceptions. Therefore, this project aims to ....Harnessing Business Insights from Unstructured Customer Data. Resulting from customers’ widespread uptake of online channels to buy and communicate has been a surge in online reviews and social media posts. This textual information offers a viable alternative to surveys that Australian businesses currently conduct to obtain customer insights. However, these reviews are unstructured and require substantial pre-processing to extract underlying customer perceptions. Therefore, this project aims to develop a novel machine learning approach to quantify the business-relevant information contained in textual information shared by customers online. This alternative approach will provide significant cost-saving benefits for a range of Australian companies, such as retailers, hotels, airlines and restaurants.Read moreRead less

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.
