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
Age at first birth, mode of conception and adjustment to parenthood. The trend to delayed childbearing is well-established, multiply determined and unlikely to change in the short term. This study will provide contemporary Australian evidence on the experience of becoming a parent at different ages, naturally and through assisted conception, for Australian men and women. Both risk and protective factors for older first-time parents will be identified, thus informing policy and services that can ....Age at first birth, mode of conception and adjustment to parenthood. The trend to delayed childbearing is well-established, multiply determined and unlikely to change in the short term. This study will provide contemporary Australian evidence on the experience of becoming a parent at different ages, naturally and through assisted conception, for Australian men and women. Both risk and protective factors for older first-time parents will be identified, thus informing policy and services that can better support Australian families with planning and rearing children. A key outcome will be a Parenting Decision-Aid to provide evidence-based reader-friendly information about the positives and negatives of first-time parenthood at different ages.Read moreRead less
Retirement transition: a longitudinal P-E fit approach within a 'life expectancy' time framework. Retirement is an important career milestone, heralding the onset of potentially significant changes in health, finance, and activity. Australia's largest birth cohort, the baby boomers, is ageing and beginning the transition into retirement and yet little is known about how the shifts in culture and attitude will affect their ability to adjust. This research will identify the dominant needs of this ....Retirement transition: a longitudinal P-E fit approach within a 'life expectancy' time framework. Retirement is an important career milestone, heralding the onset of potentially significant changes in health, finance, and activity. Australia's largest birth cohort, the baby boomers, is ageing and beginning the transition into retirement and yet little is known about how the shifts in culture and attitude will affect their ability to adjust. This research will identify the dominant needs of this group, the resources required to fulfil them, and the factors associated with successful adjustment behaviours. Greater understanding on how self-rated longevity, health, finance and values interact to affect decision-making will have important implications for public policy and individual planning.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
The role of preferred brain states in perceptual and cognitive processing: New insights into brain dynamics. New insights into brain dynamics will improve our understanding of both normal and atypical functioning. Extending previous work on normals will confirm how innovative Australian approaches can lead the research agenda in basic neuroscience, at the psychology-physiology interface. Testing in AD/HD and elderly populations will clarify dysfunctional brain mechanisms underlying AD/HD, and th ....The role of preferred brain states in perceptual and cognitive processing: New insights into brain dynamics. New insights into brain dynamics will improve our understanding of both normal and atypical functioning. Extending previous work on normals will confirm how innovative Australian approaches can lead the research agenda in basic neuroscience, at the psychology-physiology interface. Testing in AD/HD and elderly populations will clarify dysfunctional brain mechanisms underlying AD/HD, and the cognitive losses in elderly populations (exacerbated by dementia). These results may lead to better diagnosis, treatment, and community understanding of these groups. Also, publications on these target groups will demonstrate internationally the widespread utility of this approach, encouraging further novel applications of basic neuroscience in health.Read moreRead less
Psychosocial and cognitive outcomes of residential relocation and retirement: The TRAnsitions In Later Life (TRAILL) project.

Our multidisciplinary investigation will yield Australia's first major body of knowledge on the socio-economic determinants of health and health inequalities over the life course. It will point the way towards policies that can promote health and reduce the health inequalities experienced by disadvantaged individuals and families. It will indicate how improving the health of ageing Australian men and women can increase productivity and reduce needs for health services during the rapid population ageing that lies ahead. Comparisons with England will inform policy choices. We will train researchers who will play a future role in building Australia's evidence base to guide constructive policies to 2020 and beyond.Read moreRead less
An epigenetic basis for foetal programming. The social and economic impact of adult-onset diseases such as diabetes, hypertension and atherosclerosis is increasing. Evidence indicates that a mother's nutrition influences the risk of her children developing some diseases later in life. This proposal aims to elucidate the mechanism underlying this phenomenon. By understanding the mechanism through which maternal nutrition affects disease risk, we may make it possible to design early diagnosis and ....An epigenetic basis for foetal programming. The social and economic impact of adult-onset diseases such as diabetes, hypertension and atherosclerosis is increasing. Evidence indicates that a mother's nutrition influences the risk of her children developing some diseases later in life. This proposal aims to elucidate the mechanism underlying this phenomenon. By understanding the mechanism through which maternal nutrition affects disease risk, we may make it possible to design early diagnosis and intervention strategies. Our work may suggest intervention strategies - such as supplementation of at-risk mothers with key molecules such as methyl donors - during foetal and early postnatal life, which could be key to preventing premature morbidity and mortality.Read moreRead less
Surface engineering of biomaterials for optimal bone bonding characteristics. The ideal bone-implant material is hydroxyapatite. Chemically similar to bone mineral, hydroxyapatite is capable of inducing bone ongrowth. An ideal surface coating for metal hip implants, plasma spraying has been the preferred commercial hydroxyapatite coating technique. Until recently, it was always presumed that the bioactivity of hydroxyapatite resulted from its surface chemistry. However, a recent study has shown ....Surface engineering of biomaterials for optimal bone bonding characteristics. The ideal bone-implant material is hydroxyapatite. Chemically similar to bone mineral, hydroxyapatite is capable of inducing bone ongrowth. An ideal surface coating for metal hip implants, plasma spraying has been the preferred commercial hydroxyapatite coating technique. Until recently, it was always presumed that the bioactivity of hydroxyapatite resulted from its surface chemistry. However, a recent study has shown that the bioactivity of HAp coatings strongly correlates with surface roughness on the scale of bone cells. This project will explore cell-attachment behaviour for hydroxyapatite coatings prepared by plasma spraying compared with engineered surface morphology/chemistry by microlithography and vapour coating.Read moreRead less
