The entrainment of circadian rhythms in marsupial mammals: behavioural and sub-cellular investigation of non-rod, non-cone ocular photoreceptors. Our investigation will provide a contribution to understanding the role that photoreceptors play in the mechanisms that control circadian rhythms and will ultimately lead to a better understanding of the basic physiology of sleep and circadian cycles, their contribution to learning and memory and their impact on waking performance. Targeted drug develo ....The entrainment of circadian rhythms in marsupial mammals: behavioural and sub-cellular investigation of non-rod, non-cone ocular photoreceptors. Our investigation will provide a contribution to understanding the role that photoreceptors play in the mechanisms that control circadian rhythms and will ultimately lead to a better understanding of the basic physiology of sleep and circadian cycles, their contribution to learning and memory and their impact on waking performance. Targeted drug development and the design of lighting systems effective in regulating circadian rhythms will improve the quality of life and competitiveness of the many citizens who endure abnormal sleep/wakefulness schedules.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
Time discounting in late career financial and activity planning. A new career decision model of retirement activity and financial planning will be tested that combines hyperbolic delay discounting with exponential interest growth, while also examining the impact of risk framed in terms of changing goverment tax legislation and uncertain health.

A new career decision model of retirement activity and financial planning will be tested that combines hyperbolic delay discounting with exponential interest growth, while also examining the impact of risk framed in terms of changing goverment tax legislation and uncertain health. The role of expertise and simulated training in reducing time discounting will be examined, and results combined to form a late career web assistance program. Improving predictions of the decision to retire will benefit individuals, financial planners, investors and employing organisations.Read moreRead less
Too close for comfort? Adoption and management of professional and personal roles in rural welfare practice. Stressors such as maintaining role boundaries, dual and multiple relationships, professional practice, personal and family safety exist for rural welfare professionals who live and work in the same communities. Rural social welfare practice presents dilemmas due to potential conflicts between personal and work roles. The study examines individual attributes for coping and resilience, and ....Too close for comfort? Adoption and management of professional and personal roles in rural welfare practice. Stressors such as maintaining role boundaries, dual and multiple relationships, professional practice, personal and family safety exist for rural welfare professionals who live and work in the same communities. Rural social welfare practice presents dilemmas due to potential conflicts between personal and work roles. The study examines individual attributes for coping and resilience, and contextual issues. Implications for employing agencies, and educational and training institutions regarding recruiting, retention and training welfare professionals, as well as management of occupational health and safety concerns will be highlighted. The study will provide recommendations for employing agencies, professional associations, and educational institutions.Read moreRead less
Responding to self-conceptual uncertainty: Orthodoxy, diversity, and social identity in groups and society. Some groups in society are ethnocentric and xenophobic, embracing orthodoxy, homogeneity and hierarchy. They suppress diversity and dissent. Other groups embrace diversity, and are wary of homogeneity and hierarchy. Project explores the social psychology of identity and group membership, to answer the question why some groups are orthodox whereas others are diverse. Uncertainty about one's ....Responding to self-conceptual uncertainty: Orthodoxy, diversity, and social identity in groups and society. Some groups in society are ethnocentric and xenophobic, embracing orthodoxy, homogeneity and hierarchy. They suppress diversity and dissent. Other groups embrace diversity, and are wary of homogeneity and hierarchy. Project explores the social psychology of identity and group membership, to answer the question why some groups are orthodox whereas others are diverse. Uncertainty about one's group identity is aversive; automatically motivating identification with groups that are distinct entities with sharp boundaries, consensual properties, and homogeneous membership. However, internally diverse groups can also be distinct (often better functioning) entities. Buffering of automatic reactions to uncertainty may favour diverse over orthodox groups.Read moreRead less
The Analog Mind: Connectionism, Consciousness and Mental Representation. The aim of our project is to explore novel conjectures about the way information is coded and processed in the brain, and the manner in which the brain manufactures consciousness. This work may eventually pay rich dividends by reducing the incidence of mental illnesses, such as schizophrenia, that disturb conscious experience. It may also lead to the development of more powerful forms of computation in artificial neural ne ....The Analog Mind: Connectionism, Consciousness and Mental Representation. The aim of our project is to explore novel conjectures about the way information is coded and processed in the brain, and the manner in which the brain manufactures consciousness. This work may eventually pay rich dividends by reducing the incidence of mental illnesses, such as schizophrenia, that disturb conscious experience. It may also lead to the development of more powerful forms of computation in artificial neural networks. This will have a significant impact on the artificial intelligence industry, with obvious economic benefits for Australia.

A unified theory of performance in absolute identification tasks. The ability to identify stimuli is fundamentally important in human cognition and is studied in absolute identification tasks, where people must identify one out of a number of stimuli, varying on a single dimension, with an appropriate label. A remarkable finding is that people cannot reliably identify more than about seven different stimuli. This limit imposes severe practical restrictions on our ability to categorise stimuli an ....A unified theory of performance in absolute identification tasks. The ability to identify stimuli is fundamentally important in human cognition and is studied in absolute identification tasks, where people must identify one out of a number of stimuli, varying on a single dimension, with an appropriate label. A remarkable finding is that people cannot reliably identify more than about seven different stimuli. This limit imposes severe practical restrictions on our ability to categorise stimuli and constitutes a perplexing problem for cognitive theory. This project involves an international collaborative effort by five leading researchers in mathematical psychology to develop a comprehensive, integrative model of human performance in absolute identification tasks.

Unconscious processing: To what extent, how flexible and how smart? We are unaware of the sophisticated pattern analyses conducted by our perceptual systems that enable us to operate in a complex environment. Less clear is whether unconsciously presented information itself can influence our behaviour or indeed whether unconscious cognition occurs.

We are unaware of the sophisticated pattern analyses conducted by our perceptual systems that enable us to operate in a complex environment. Less clear is whether unconsciously presented information itself can influence our behaviour or indeed whether unconscious cognition occurs. The proposed studies provide the foundation and structure for a pioneering examination of the extent, flexibility and computational power of unconscious processing at the level of neural response and behaviour. The impact and benefits of the project will be in its contribution to theory with outcomes revealing the boundary conditions governing unconscious cognition and providing a first benchmark for how such conditions might vary across the lifespan.Read moreRead less
Models of Knowledge Restructuring. In a world of rapid change, people must frequently adapt cognitive skills to new technologies. This often requires restructuring of knowledge, from simple initial strategies to increasingly complex ways of mastering the task. This is not always easy and people sometimes resist knowledge restructuring. We present a network model of knowledge restructuring that combines attentional processes with error-driven learning. The model accounts for several existing resu ....Models of Knowledge Restructuring. In a world of rapid change, people must frequently adapt cognitive skills to new technologies. This often requires restructuring of knowledge, from simple initial strategies to increasingly complex ways of mastering the task. This is not always easy and people sometimes resist knowledge restructuring. We present a network model of knowledge restructuring that combines attentional processes with error-driven learning. The model accounts for several existing results and makes predictions that guide the proposed research. Three factors will be examined empirically: (1) the role of directing attention to alternative strategies; (2) the imperfection of existing knowledge; and (3) the complexity of alternative strategies.Read moreRead less

Australia is at the forefront of research that is taking brain imaging and interfacing out of the lab and into the field. The technology being developed is spawning applications in areas as diverse as health, education, defense and national security, and will lead to resolution of longstanding theoretical debates as well as enabling new breakthroughs in understanding the biological concomitants of psychological function. This is significant given the push to develop biometrics of psychological function with enhanced sensitivity and specificity in clinical diagnosis, along with defense applications in evaluation of critical personnel and training. It also opens up a range of applications for mental control of remote or prosthetic devices.Read moreRead less
