The success and continuation of science programs in upper secondary school and university is dependent on foundational improvements in science education in lower secondary schools. This proposal is designed to address this national concern by fostering talent in science and encouraging more students to study and enjoy science in a meaningful way. Through planned formative assessment, teachers will enable students in Years 8-10 to think about the science concepts and consider alternative explanations rather than memorise basic facts for a test or examination which are then forgotten. Practical benefits are a large range of valid and reliable tests and a range of teaching approaches for diagnosing student learning difficulties.Read moreRead less
Goal pursuit decisions under environmental and social uncertainty. This project aims to develop an integrative computational model that explains how people prioritise the allocation of resources to different goals in the face of uncertainty. The project seeks to test a new theory through a series of experiments in which participants pursue goals by themselves in unpredictable environments, or in competition against an opponent. Expected outcomes include an integrated theory that accounts for the ....Goal pursuit decisions under environmental and social uncertainty. This project aims to develop an integrative computational model that explains how people prioritise the allocation of resources to different goals in the face of uncertainty. The project seeks to test a new theory through a series of experiments in which participants pursue goals by themselves in unpredictable environments, or in competition against an opponent. Expected outcomes include an integrated theory that accounts for the effects of both environmental and social uncertainty in the pursuit of multiple goals. Intended benefits include the development of computational models that can simulate human decision making in complex environments, analyse new concepts of operation, redesign work roles, and identify factors that reduce risk in decision-making.Read moreRead less
Modelling human decision making in complex environments. The project aims to extend quantitative psychological models of simple choice tasks to decision-making with complex stimuli in complex environments. The new formal models are designed to provide a comprehensive account of behaviour, including the choices that are made, how long it takes to make them, and how choices and choice times vary within and between decision-makers. The models would explain how people adapt to changes in task demand ....Modelling human decision making in complex environments. The project aims to extend quantitative psychological models of simple choice tasks to decision-making with complex stimuli in complex environments. The new formal models are designed to provide a comprehensive account of behaviour, including the choices that are made, how long it takes to make them, and how choices and choice times vary within and between decision-makers. The models would explain how people adapt to changes in task demands when dealing with multiple stimuli or performing multiple tasks concurrently under time pressure. The project aims to provide the basic research that is needed to extend psychological models of choice to complex ‘real-world’ tasks, such air traffic control and maritime surveillance.Read moreRead less
Information seeking, cognition, and individual differences. The public now has access to vast amounts of scientific knowledge and information on the internet and in other new media. Paradoxically, this increasing availability of knowledge has been accompanied by the increasing traction of pseudoscientific misinformation. This project explores the reasons underlying those trends and seeks solutions.
The Psychology of Misinformation—Towards A Theory-driven Understanding. The project aims to develop a psychological theory of misinformation effects. Misinformation influences people’s memory, reasoning and decision-making even after corrections – it thus poses a significant challenge for science and society. Through the combination of systematic experimentation with theory-driven computational modelling, the project will strive to concurrently consider individual-level cognition and the impact ....The Psychology of Misinformation—Towards A Theory-driven Understanding. The project aims to develop a psychological theory of misinformation effects. Misinformation influences people’s memory, reasoning and decision-making even after corrections – it thus poses a significant challenge for science and society. Through the combination of systematic experimentation with theory-driven computational modelling, the project will strive to concurrently consider individual-level cognition and the impact of sociocultural context. It is anticipated that this novel integrative approach will substantially expand our understanding of misinformation effects, and that this theoretical progress will result in the formulation of specific communication strategies to reduce the impact of misinformation on society.Read moreRead less
Developing a integrated memory-based model of evaluation and choice. People's judgements and choices are unstable. This project intends to examine one potential source of this instability: the memories that come to mind when people are evaluating choices. Many of the choices we make in our everyday lives are made on the basis of remembered information, and yet theories of evaluation and choice typically do not account for the role of memory, or provide only a cursory account of its role. In the ....Developing a integrated memory-based model of evaluation and choice. People's judgements and choices are unstable. This project intends to examine one potential source of this instability: the memories that come to mind when people are evaluating choices. Many of the choices we make in our everyday lives are made on the basis of remembered information, and yet theories of evaluation and choice typically do not account for the role of memory, or provide only a cursory account of its role. In the project, people will be presented with value information, and the project plans to examine how that information is retrieved from memory and then used to evaluate options and make decisions. Expected project outcomes would provide a coherent model that provides an integrated understanding of the role of memory in judgement and choice.Read moreRead less
Developing group-based elicitation methods to improve decision making. This project aims to develop an elicitation methodology enabling multiple members of a team to contribute to the same technical problem - enabling expertise to be accurately combined while avoiding group and individual sources of bias. Good elicitation methods minimise bias in estimates and forecasts - which otherwise erode value and lead to sub-optimal decision making. Existing methods, however, ignore group structures; that ....Developing group-based elicitation methods to improve decision making. This project aims to develop an elicitation methodology enabling multiple members of a team to contribute to the same technical problem - enabling expertise to be accurately combined while avoiding group and individual sources of bias. Good elicitation methods minimise bias in estimates and forecasts - which otherwise erode value and lead to sub-optimal decision making. Existing methods, however, ignore group structures; that is that decisions made by, or on, the advice of teams have different characteristics than individual decisions and often preclude the use of methods designed to limit individuals' biases. By encoding the method into a computerised tool the project will assist public and private sector enterprises to improve group decision making.Read moreRead less
Investigation of the component distributions of pause duration in spontaneous speech: Constraints for models of language production. We have discovered that the distribution of pause durations in spontaneous speech of individual speakers can be decomposed into at least two log-normal distributions. Our project will investigate this finding and provide a foundation for new research relevant to language production models. This will be achieved by determining the semantic, lexical, psycholinguistic ....Investigation of the component distributions of pause duration in spontaneous speech: Constraints for models of language production. We have discovered that the distribution of pause durations in spontaneous speech of individual speakers can be decomposed into at least two log-normal distributions. Our project will investigate this finding and provide a foundation for new research relevant to language production models. This will be achieved by determining the semantic, lexical, psycholinguistic, physiological, and acoustic concomitants of each component distribution and by investigating the impact of selected variables on the shape and location of each. The project has important implications for models of language production and applied problems involving automatic speech recognition, forensic speaker identification, and human communication disorders.Read moreRead less
The role of episodic memory in imagining and planning for the future. For future planning we draw on past experiences. In many cases, past experiences are used to imagine novel potential scenarios yet to be experienced. This project will examine in detail the role of memory in imagining possible futures and planning for those possibilities, drawing on our contemporary understanding of memory as captured in computational models of human memory. By controlling the information that people encode in ....The role of episodic memory in imagining and planning for the future. For future planning we draw on past experiences. In many cases, past experiences are used to imagine novel potential scenarios yet to be experienced. This project will examine in detail the role of memory in imagining possible futures and planning for those possibilities, drawing on our contemporary understanding of memory as captured in computational models of human memory. By controlling the information that people encode into memory, and thus determining the building blocks from which people build simulations of the future, this project will gain valuable data that will be used to develop a detailed and precise computational model of the role of memory mechanisms and representations in imagining and planning.Read moreRead less
Modelling How Humans Adapt to Task Demands in Safety-Critical Workplaces . This project aims to explain how human operators make decisions in complex work environments that require multiple tasks to be completed under time pressure.

This project aims to explain how human operators make decisions in complex work environments that require multiple tasks to be completed under time pressure. This project expects to achieve a significant theoretical and practical advance by developing and testing a computational model of the psychological processes that allow operators to adapt to the types of workplace task demands that can increase human error and the risk of accidents. The expected outcome is a model that can explain operator decision-making and predict the conditions where operators are more likely to make delayed responses or errors. This should provide significant benefits by informing psychological theory and potentially reducing workplace incidents and accidents.Read moreRead less
