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
Developing a Unified Theory of Episodic Memory. This project aims to develop a model of episodic memory and to apply the model to both adult and child development data. Unlike current approaches, the model is expected to address multiple memory tasks including item recognition, associative recognition, source recognition and cued recall, and also aims to address reaction time data, allowing different sources of interference causing forgetting in adults to be identified. By addressing both encodi ....Developing a Unified Theory of Episodic Memory. This project aims to develop a model of episodic memory and to apply the model to both adult and child development data. Unlike current approaches, the model is expected to address multiple memory tasks including item recognition, associative recognition, source recognition and cued recall, and also aims to address reaction time data, allowing different sources of interference causing forgetting in adults to be identified. By addressing both encoding and retrieval processes, the model can assess how changes in different sources of interference modulate performance through the trajectory of early development. Hierarchical Bayesian estimation aims to enable a simultaneous account of multiple tasks and support future deployment in applied contexts.Read moreRead less
Rapid decisions: from neuroscience to complex cognitions. A succession of rapid decisions supports our daily life - run or walk? Fish or steak? This project will integrate three different approaches to understanding these decisions, from neuroscience, mathematical psychology and experimental psychology. This research will provide insights about normal human functioning, and problems such as occur in healthy ageing.
Perceiving and tracking moving objects. Processing and tracking moving objects poses challenges for human perception. To succeed, visual processing must accumulate analyses of the object from its different positions. Perceptual experiments will reveal human limits and yield insights into the underlying mechanisms, providing a basis for understanding object tracking in tasks like driving.
How feedback can impair recognition judgments and undermine border security, criminal investigations, educational testing, and medical screening. If a customs officer learns that they have missed an explosive device while screening luggage, will this affect their judgment? In many scenarios, a person receives feedback about their recognition memory performance and has to try again without having another chance to study the material. Almost no research has examined the effects of feedback on reco ....How feedback can impair recognition judgments and undermine border security, criminal investigations, educational testing, and medical screening. If a customs officer learns that they have missed an explosive device while screening luggage, will this affect their judgment? In many scenarios, a person receives feedback about their recognition memory performance and has to try again without having another chance to study the material. Almost no research has examined the effects of feedback on recognition in the absence of opportunity for further study. This is problematic because many vitally important recognition decisions lack such opportunity. Using various scenarios (face recognition, security screening, multiple-choice testing, and medical screening) this project will demonstrate that feedback affects recognition performance differently depending on the nature of the recognition decision.Read moreRead less
How do myelinating cells alter brain circuits to facilitate learning? This project aims to identify the brain circuits that receive new insulation and characterise the molecular mediators of this process. This project will apply innovative technologies to understand how the nervous system remains adaptable throughout life. This new knowledge, of the cellular mechanisms that allow brain circuits to remain adaptable throughout life, may have application in the development of interventions aimed at ....How do myelinating cells alter brain circuits to facilitate learning? This project aims to identify the brain circuits that receive new insulation and characterise the molecular mediators of this process. This project will apply innovative technologies to understand how the nervous system remains adaptable throughout life. This new knowledge, of the cellular mechanisms that allow brain circuits to remain adaptable throughout life, may have application in the development of interventions aimed at improving educational outcomes or counteracting age-related memory decline. Potential future benefits include facilitating the development of drugs to circumvent memory loss resulting from brain diseases, and improving the design of neuromorphic hardware for computing.Read moreRead less

This project will inform the community about factors that affect the psychological, physical, academic, and employment outcomes of emerging adults. It will improve our knowledge of why some young people do not reach their full potential. The project will provide a comprehensive assessment of factors associated with well-being across several domains. It will better equip and assist professionals to identify early those youth at risk of having poor psychological, health, and employment prospects post-school. The project will inform the development of intervention programs for young people and maximise their overall adjustment and well-being several years later.Read moreRead less
Lags and legacies: antecedent effects on grassland biomass response to carbon dioxide. This project aims to assess how past conditions influence grassland responses to the rising atmospheric concentration of carbon dioxide. High CO2 concentrations should stimulate productivity but in grasslands this is rarely realised because other, mostly unknown, factors constrain the response. By synthesising data from past experiments, this project aims to determine exactly why grasslands fail to realise the ....Lags and legacies: antecedent effects on grassland biomass response to carbon dioxide. This project aims to assess how past conditions influence grassland responses to the rising atmospheric concentration of carbon dioxide. High CO2 concentrations should stimulate productivity but in grasslands this is rarely realised because other, mostly unknown, factors constrain the response. By synthesising data from past experiments, this project aims to determine exactly why grasslands fail to realise the full productivity benefits of increased CO2 and when this will happen. This should improve predictions of carbon exchange and indicating the best direction for climate change adaptation measures.Read moreRead less
The ageing brain: plasticity and training. This project will investigate how the capacity of a person's brain for reorganisation (plasticity) influences cognitive and motor function and training benefits in older adults. The findings will support new training initiatives to promote brain health and well-being across the lifespan.
Methods of Topology: Boundary, Surface and the Inner/Outer in Kant and Wittgenstein. Ways of 'inclusion' vs. 'exclusion' are of basic and pivotal significance in social and political scenarios, e.g. of establishing identities and conducting intra- and transnational discourses. At the root of these discourses lies a vague and implicit 'metaphysics' of the nature of the 'internal', of distinction and discrimination, fostered by intuitions of alleged privileged access to the 'inner'. The project ha ....Methods of Topology: Boundary, Surface and the Inner/Outer in Kant and Wittgenstein. Ways of 'inclusion' vs. 'exclusion' are of basic and pivotal significance in social and political scenarios, e.g. of establishing identities and conducting intra- and transnational discourses. At the root of these discourses lies a vague and implicit 'metaphysics' of the nature of the 'internal', of distinction and discrimination, fostered by intuitions of alleged privileged access to the 'inner'. The project has direct impact on the de-mystification of these socially central notions, its institutional misapprehensions and cultural implications. The project is a paradigm case of how thorough philosophical analysis can yield concrete results, contributing to an understanding of personal, social and political boundaries and demarcations.Read moreRead less
