Summary
It has been proposed that engagement in purposeful complex mental stimulation provides protection against dementia. The Tasmanian Healthy Brain Project (THBP) is a unique, large-scale prospective trial that examines whether university-level study in older adult population reduces ageing-related cognitive decline and risk of dementia. This project will also examine how an individual’s genetic profile may influence the potential benefits of complex mental stimulation as well as risk of dementia.
The Healthy Brain Project: A Prospective Cohort Study To Examine How Later-life University Education May Affect The Trajectory Of Ageing-related Cognitive Decline

Summary
Previous research has indicated that higher levels of education in early adulthood are associated with lower risk for dementia in older adults. This world-first project will examine if older adults who undertake university education have reduced rates of age-related cognitive decline than older adults who do not undertake further education. This would support the notion that boosting cognitive reserve in later life is protective against age- and disease-related neurodegenerative change.
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.

The ARC Research Network on Ageing Well will support interdisciplinary, high quality research in the National Research Priority Goal of Ageing Well, Ageing Productively. It will build scale and focus on Australia's notable research strengths in ageing, promote collaborative research, and extend research capacities. The Network will link outstanding researchers from many disciplines, nurture developing researchers, relate social to health researchers, strengthen international collaboration, and involve and inform end-point users. It will foster research which responds to the aspirations and needs of older Australians and informs action that can improve experiences of individual and population ageing.Read moreRead less
Promoting employee mental health through the development of managers' psychological capital: A controlled field experiment. Depression significantly impacts Australian communities and costs the economy approximately 12 million days in lost productivity each year. By delivering a mental health promotion program to managers of small-medium enterprises, this study will enhance the psychological wellbeing and mental health literacy of managers in a sector of the business community often neglected in ....Promoting employee mental health through the development of managers' psychological capital: A controlled field experiment. Depression significantly impacts Australian communities and costs the economy approximately 12 million days in lost productivity each year. By delivering a mental health promotion program to managers of small-medium enterprises, this study will enhance the psychological wellbeing and mental health literacy of managers in a sector of the business community often neglected in occupational health research. The program targets managers within Tasmania, a setting representing regional communities in which people have a higher risk of mental ill-health problems. Read moreRead less
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

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
