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
Extending Cognitive Models to Account for Individual Differences. Despite their impressive achievements, cognitive models of memory retention, category learning, and stimulus representation usually model people as ?invariants?, concentrating on what makes them the same. This project aims to extend all three types of model to also treat people as ?individuals?, and account for how people are different. Advanced model selection methods will be used to do this in a way that is complete, general, an ....Extending Cognitive Models to Account for Individual Differences. Despite their impressive achievements, cognitive models of memory retention, category learning, and stimulus representation usually model people as ?invariants?, concentrating on what makes them the same. This project aims to extend all three types of model to also treat people as ?individuals?, and account for how people are different. Advanced model selection methods will be used to do this in a way that is complete, general, and principled. The outcome will be a set of new theoretical models, and new algorithms to learn the models from empirical data, that explain the differences between people in remembering, learning and representing information.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. 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 address fundamental issues in visual working memory.Read moreRead less
Towards an integrated model of reasoning and reasoning development. This project aims to identify the core cognitive processes that underlie different forms of reasoning and how they develop. The project intends to use a signal detection framework to derive detailed computational models of reasoning which can then be tested through Bayesian computational modelling as well as the first systematic investigation of developmental change in reasoning processes. Expected outcomes include a more princi ....Towards an integrated model of reasoning and reasoning development. This project aims to identify the core cognitive processes that underlie different forms of reasoning and how they develop. The project intends to use a signal detection framework to derive detailed computational models of reasoning which can then be tested through Bayesian computational modelling as well as the first systematic investigation of developmental change in reasoning processes. Expected outcomes include a more principled and comprehensive computational model of reasoning in both adults and children. The project should provide significant benefits by helping to resolve long-standing debates about how humans reason complex arguments relevant to everyday lives and guide development of more effective methods for teaching reasoning.Read moreRead less
Understanding middle-aged women’s responses to alcohol/breast cancer risks. This project aims to identify the nature of alcohol consumption patterns by Australian women aged 45-64 in different socio-economic status groups, and how these are shaped in response to considerations of trust and future health risks. The project will focus on the known risk of alcohol for the development of breast cancer, which is particularly important given that Australian culture is saturated by alcohol use, marketi ....Understanding middle-aged women’s responses to alcohol/breast cancer risks. This project aims to identify the nature of alcohol consumption patterns by Australian women aged 45-64 in different socio-economic status groups, and how these are shaped in response to considerations of trust and future health risks. The project will focus on the known risk of alcohol for the development of breast cancer, which is particularly important given that Australian culture is saturated by alcohol use, marketing and social acceptability. This project aims to identify new strategies to transform behaviour change initiatives, which may differ by socio-economic status group. The project will be a model for national and global initiatives that seek to develop highly effective alcohol reduction messages and reduce alcohol-related harms.Read moreRead less
Uncovering the processes underlying human reasoning: A state-trace approach. This project aims to answer the most important unresolved question in the psychology of reasoning; how many distinct cognitive processes underlie human reasoning? To answer this question, this project aims to conduct an extensive experimental investigation of the factors that selectively impact inductive and deductive inferences and the application of high-dimensional state-trace analysis; a powerful new method for diag ....Uncovering the processes underlying human reasoning: A state-trace approach. This project aims to answer the most important unresolved question in the psychology of reasoning; how many distinct cognitive processes underlie human reasoning? To answer this question, this project aims to conduct an extensive experimental investigation of the factors that selectively impact inductive and deductive inferences and the application of high-dimensional state-trace analysis; a powerful new method for diagnosing underlying processes from behavioural data. The project is expected also to develop a new computational model that accounts for both inductive and deductive forms of reasoning.Read moreRead less
Single and dual process models of recognition memory: Reconciliation of behavioural, electrophysiological, and neuroimaging data. Advanced brain scanning technologies are increasingly used to study human memory. As well as being important for our basic understanding of memory, they also tell us how memory is affected by normal development, ageing, disease, and injury. Unfortunately, because these technologies are so new, a gap has opened up between our psychological understanding of memory and t ....Single and dual process models of recognition memory: Reconciliation of behavioural, electrophysiological, and neuroimaging data. Advanced brain scanning technologies are increasingly used to study human memory. As well as being important for our basic understanding of memory, they also tell us how memory is affected by normal development, ageing, disease, and injury. Unfortunately, because these technologies are so new, a gap has opened up between our psychological understanding of memory and the physiological events measured by the scanning technologies. This has created a problem for how we should interpret the results that are found. The present project aims to close this gap by applying new research methodologies and theoretical insights based on our previous research.Read moreRead less
Social practices of oral health in Australian preschool children. The aim of the study is to explore "social practices" of oral health in Australian (Aboriginal and non-Aboriginal) preschool children. We use this emerging theory to move away from focusing on individuals and individual behaviour (and blame) to identify and map social practices: actions, materials and meanings families attribute to
child’s oral health. Expected project outcomes include identifying practices promoting or underminin ....Social practices of oral health in Australian preschool children. The aim of the study is to explore "social practices" of oral health in Australian (Aboriginal and non-Aboriginal) preschool children. We use this emerging theory to move away from focusing on individuals and individual behaviour (and blame) to identify and map social practices: actions, materials and meanings families attribute to
child’s oral health. Expected project outcomes include identifying practices promoting or undermining children’s oral health that can inform upstream and downstream policy directions and practices to improve health outcomes. This offers a new approach to "wicked" problems such as oral health where extensive
effort has not reduced morbidity and cost despite rhetoric that oral health is preventable.Read moreRead less
Global dementias: Examining structural vulnerability and dementia outcomes. This project aims to examine the social and cultural dimensions of dementia by using a comparative ethnographic approach to examine the experiences of people living with dementia in Australia, Malaysia and India. The project expects to generate new anthropological knowledge about structural inequalities by examining how dementia is responded to in diverse geographic, cultural and social settings.

This project aims to examine the social and cultural dimensions of dementia by using a comparative ethnographic approach to examine the experiences of people living with dementia in Australia, Malaysia and India. The project expects to generate new anthropological knowledge about structural inequalities by examining how dementia is responded to in diverse geographic, cultural and social settings. Expected outcomes of this project include the creation of a new evidence-base on dementia and the production of briefing documents to guide global health frameworks. The project should provide significant benefits for people living with dementia by providing locally-relevant strategies to respond to dementia and resultant disability.Read moreRead less
Investigation of recognition memory in behavioural, electrophysiological, and functional neuro-imaging domains using state-trace analysis. This project utilises a novel methodology to investigate human recognition memory across three separate domains - behavioural, electrophysiological and functional neuro-imaging. The aim is to determine how these three aspects of memory are related and if they can be united by a single theory.
