Current machine learning and optimisation methods cannot well support sequential prediction and decision-making due to the dynamic nature and pervasive presence of big data. This project aims to create a foundation and technology for sequence and uncertainty learning, sequential and dynamic optimisation, and their integration. It is expected to improve robustness and mitigate the vulnerabilities of machine learning algorithms, to increase prediction accuracy and reliability in dynamic sequences, and to support decision-making in complex situations to achieve robust and adaptive results. Anticipated outcomes can help data scientists with state-of-the-art skills to manage sequential data and benefit data-enabled innovation in Australia.Read moreRead less
Robust meta learning for risk-aware recommender systems. Recommender systems are the core of many online services but they are highly vulnerable to risks like shilling attacks, privacy leaks, and unexpected change. This project aims to develop new adversarial Bayesian-based, privacy-preserved and self-adaptive fuzzy meta learning methods and meta recommender systems that are robust to these risky, uncertain and dynamic environments. The anticipated outcomes should significantly improve the relia ....Robust meta learning for risk-aware recommender systems. Recommender systems are the core of many online services but they are highly vulnerable to risks like shilling attacks, privacy leaks, and unexpected change. This project aims to develop new adversarial Bayesian-based, privacy-preserved and self-adaptive fuzzy meta learning methods and meta recommender systems that are robust to these risky, uncertain and dynamic environments. The anticipated outcomes should significantly improve the reliability of recommender systems with particular benefits for online personalised service systems, e.g., e-government, e-business and e-Learning. The outcomes will also advance machine learning knowledge with a new robust meta learning schema for general data analytics and applications.Read moreRead less
Misinformation: Evidence evaluation in an alternate fact reality . This project aims to understand why people believe misinformation. Misinformation causes some people to adopt implausible beliefs. These beliefs pose a significant challenge for society because they can result in behaviours that negatively impact personal and public safety. By combining surveys, qualitative analysis, and systematic experimentation, this project will identify differences in evidence evaluation and persuasiveness b ....Misinformation: Evidence evaluation in an alternate fact reality . This project aims to understand why people believe misinformation. Misinformation causes some people to adopt implausible beliefs. These beliefs pose a significant challenge for society because they can result in behaviours that negatively impact personal and public safety. By combining surveys, qualitative analysis, and systematic experimentation, this project will identify differences in evidence evaluation and persuasiveness between people who believe misinformation and those who do not. It is anticipated that our novel approach will build knowledge about misinformation effects and will reduce associated harms by expanding our understanding of how to communicate effectively with people who are persuaded by misinformation.Read moreRead less
Improving novice drivers' speed and hazard management. The aim of the study is to extend the evidence-based approach we have developed for speed management (cognitive integration speed management training) to hazard management, thereby developing cognitive integration hazard management training for young drivers. Hence, this study is specifically designed to curb the alarming trend in young driver fatalities on Australian roads. The results of the research will provide clear direction to road au ....Improving novice drivers' speed and hazard management. The aim of the study is to extend the evidence-based approach we have developed for speed management (cognitive integration speed management training) to hazard management, thereby developing cognitive integration hazard management training for young drivers. Hence, this study is specifically designed to curb the alarming trend in young driver fatalities on Australian roads. The results of the research will provide clear direction to road authorities and driver training providers as to effective training strategies to improve young driver training, and ultimately improve road safety with this vulnerable population.Read moreRead less
Towards a cognitive process model of how attention and choice interact. Before making any decision, we must gather information on what options are available. This process may influence the choices we make: if we do not notice an option, we will not choose it even if it would have been valuable. This project aims to examine how prior experience can produce attentional biases that influence decisions, and will develop a new computational model of this interaction of attention and choice as an outc ....Towards a cognitive process model of how attention and choice interact. Before making any decision, we must gather information on what options are available. This process may influence the choices we make: if we do not notice an option, we will not choose it even if it would have been valuable. This project aims to examine how prior experience can produce attentional biases that influence decisions, and will develop a new computational model of this interaction of attention and choice as an outcome. This new knowledge will enhance the world-class status of Australian cognitive psychology. Moreover, it should provide significant benefits through improving our ability to predict and shape behaviour, and shedding light on the role of biases in healthy cognition and in the context of compulsive behaviours.Read moreRead less
Gaining control of the future: The cognitive development of foresight. Because humans can anticipate their limitations, they can act in the present to shape their future for the better.
This project aims to chart four key developmental processes by which children gain this control over their future
outcomes. It will use novel experimental paradigms to map children’s growing ability to compensate for their limits
with strategic planning, and to improve their future capacities by acquiring new kno ....Gaining control of the future: The cognitive development of foresight. Because humans can anticipate their limitations, they can act in the present to shape their future for the better.
This project aims to chart four key developmental processes by which children gain this control over their future
outcomes. It will use novel experimental paradigms to map children’s growing ability to compensate for their limits
with strategic planning, and to improve their future capacities by acquiring new knowledge and innovating
technical solutions. The cognitive underpinnings of these critical behaviours are still poorly understood. This
project will therefore provide the essential empirical foundation for fostering the development of wiser, more
skilled, and more innovative young people.Read moreRead less
Eyes on the prize: Investigating attentional economics. We spend our lives surrounded by stimuli relating to reward and risk (adverts, games, social media etc). Recent research suggests that learning about reward and risk influences our attention, often despite our best efforts. This project will build on recently developed procedures using eye-tracking to investigate how learning about reward and risk modulates what we pay attention to, and what we ignore. Findings will be used to develop compu ....Eyes on the prize: Investigating attentional economics. We spend our lives surrounded by stimuli relating to reward and risk (adverts, games, social media etc). Recent research suggests that learning about reward and risk influences our attention, often despite our best efforts. This project will build on recently developed procedures using eye-tracking to investigate how learning about reward and risk modulates what we pay attention to, and what we ignore. Findings will be used to develop computational models of ‘attentional economics’ that account for, and predict, when we will be distracted by reward- and risk-related stimuli. This research will enhance the world-class status of Australian cognitive psychology, and will shed light on processes implicated in addiction and related behaviours.Read moreRead less
Context dependent flower choice in honey bees. This project aims to discover the strategies honey bees use when choosing between multiple flowers. The choices that honey bees make about which flowers to visit and which to avoid has significant impacts on crop yields, the spread of invasive weeds, and the conservation of native plants. This project expects to generate new knowledge in the fields of behavioural and pollination ecology through a combination of field experiments and modelling.

The choices that honey bees make about which flowers to visit and which to avoid has significant impacts on crop yields, the spread of invasive weeds, and the conservation of native plants. This project expects to generate new knowledge in the fields of behavioural and pollination ecology through a combination of field experiments and modelling. Expected outcomes of this project include enhanced capacity in the field of pollination ecology, and new insight into flower preferences in the world’s most important commercial pollinator. This should provide significant benefits to food production and security as one third of the world’s crops benefit from insect pollination.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.

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 aim of this project is to understand the role of dopamine in the brain circuits controlling goal-directed action. Its significance lies in our use of newly developed tools to measure dopamine release and cellular activity concurrently to assess the causal role of this interaction in choice and decision-making. The expected outcome of this project is to provide a comprehensive understanding of the role of dopamine release in striatal cellular activity and in the psychological processes mediating goal-directed decision-making. This outcome will have the benefit of filling a gap in our knowledge of the brain processes mediating decision-making, a fundamental capacity that contributes to our physical and psychological wellbeing (wellness).
