Ageing and self-regulation. Australia is faced with an ageing population, and thus an increasingly important national goal is ageing well and ageing productively. Our preliminary research suggests that self-regulation may be a significant problem for older Australians. The proposed research will provide a clearer picture of when and why older adults have difficulties regulating their behaviour, and which older adults are particularly susceptible to lapses in self-control. If older adults do hav ....Ageing and self-regulation. Australia is faced with an ageing population, and thus an increasingly important national goal is ageing well and ageing productively. Our preliminary research suggests that self-regulation may be a significant problem for older Australians. The proposed research will provide a clearer picture of when and why older adults have difficulties regulating their behaviour, and which older adults are particularly susceptible to lapses in self-control. If older adults do have difficulties self-regulating, and if these self-regulation failures incur health, financial and social costs, by gaining a clearer understanding of this problem, the proposed research will take an important step in improving the lives of older Australians.

Everyday cognition in older adulthood: Mechanisms contributing to the age-prospective memory paradox. Australia is faced with an ageing population, and thus an increasingly important goal is ageing well and ageing productively. The proposed research will clarify why older adults perform extremely well on prospective memory (PM) tasks based in everyday environments, but very poorly on PM tasks that take place in the controlled situation of the laboratory. Advancing our understanding of why this ....Everyday cognition in older adulthood: Mechanisms contributing to the age-prospective memory paradox. Australia is faced with an ageing population, and thus an increasingly important goal is ageing well and ageing productively. The proposed research will clarify why older adults perform extremely well on prospective memory (PM) tasks based in everyday environments, but very poorly on PM tasks that take place in the controlled situation of the laboratory. Advancing our understanding of why this 'paradoxical' pattern of age effects occurs will help clarify how other aspects of everyday cognition in older adulthood may be optimised, and consequently take an important step in improving the lives of older adults. The results will also inform development of rehabilitation strategies for clinical groups who present with PM difficulties. 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
Determining principles for successful episode retrieval of repeated events. This project aims to develop the first-ever set of explanatory principles for how people successfully retain and retrieve individual episode memories from repeated experiences (e.g., one occurrence of a routine social encounter or job-related activity). By deepening our understanding of how memory works, this new knowledge is expected to lay the foundation for interview guidance and ongoing research aimed at enhancing th ....Determining principles for successful episode retrieval of repeated events. This project aims to develop the first-ever set of explanatory principles for how people successfully retain and retrieve individual episode memories from repeated experiences (e.g., one occurrence of a routine social encounter or job-related activity). By deepening our understanding of how memory works, this new knowledge is expected to lay the foundation for interview guidance and ongoing research aimed at enhancing the proficiency of investigations into matters that rely on detailed and accurate accounts of specific episodes. This includes workplace or traffic accident investigations, infectious disease contact tracing, as well as prosecution of repeated sexual offences.Read moreRead less
Ageing, Inhibition, and Social Control - steps towards improving the lives of older adults. Australia is faced with an ageing population, and thus an increasingly important national goal is ageing well and ageing productively. The proposed research will extend our preliminary findings on ageing and social inappropriateness to provide a clearer picture of when and why this occurs, and among whom. The proposed research will also examine the mental and physical health consequences of social inappro ....Ageing, Inhibition, and Social Control - steps towards improving the lives of older adults. Australia is faced with an ageing population, and thus an increasingly important national goal is ageing well and ageing productively. The proposed research will extend our preliminary findings on ageing and social inappropriateness to provide a clearer picture of when and why this occurs, and among whom. The proposed research will also examine the mental and physical health consequences of social inappropriateness longitudinally. If cognitive losses do lead to social losses, with attendant negative health consequences, by gaining a clearer understanding of this problem, the proposed research will take an important step in improving the lives of older adults.Read moreRead less
Structured Writing Tasks: Examination of the process of change as indicated by cognitive-behavioural models of trauma. Research demonstrates that structured writing about past upsetting experiences is beneficial for physical and psychological health. The aim of this study is to identify the process of change responsible for these benefits. Three processes, based on trauma theory, have been identified (exposure, devaluation, and benefit-finding) and are manipulated within the writing paradigm. T ....Structured Writing Tasks: Examination of the process of change as indicated by cognitive-behavioural models of trauma. Research demonstrates that structured writing about past upsetting experiences is beneficial for physical and psychological health. The aim of this study is to identify the process of change responsible for these benefits. Three processes, based on trauma theory, have been identified (exposure, devaluation, and benefit-finding) and are manipulated within the writing paradigm. This study will test these processes in predicting future health benefits. It will increase the effectiveness of the writing paradigm for the general population, provide manualised variations of the writing paradigm based on trauma theory, examine patient-matching variables, and provide a base to conduct research in clinical populations.Read moreRead less
Neurocognitive substrates of naming facilitation in aphasia. This research directly addresses the national research priority goal of ageing well, ageing productively, by providing foundational knowledge for improved outcomes in the growing population of individuals in Australia with language impairments from age-related disease. Outcomes of the proposed research will include (1) development of a new theory of word production which can improve treatment of language impairment, (2) an enhanced und ....Neurocognitive substrates of naming facilitation in aphasia. This research directly addresses the national research priority goal of ageing well, ageing productively, by providing foundational knowledge for improved outcomes in the growing population of individuals in Australia with language impairments from age-related disease. Outcomes of the proposed research will include (1) development of a new theory of word production which can improve treatment of language impairment, (2) an enhanced understanding of the cognitive and brain mechanisms involved in word production and its treatment after stroke, and (3) postgraduate training in state-of-the-art cognitive neuroimaging and language neuroscience research.

Concept learning and Structure Formation for Document Navigation. This proposal is motivated by its interest in document retrieval and
discovery using formal concept analysis. The hypothesis to be tested
is that logical structures can be automatically inferred from
a document collection using information inference and
concept learning.
