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.
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
Facilitatory and inhibitory mechanisms during interlimb coordination in young and older adults. The project seeks to understand how people coordinate their limbs and the factors which limit and enhance this capacity. This is of critical importance because coordination is a dominant deficit in aging and in patients suffering brain insult and neurodegenerative diseases. Disruption of this capacity compromises individual work productivity, mobility and independence. Proficient motor functioning is ....Facilitatory and inhibitory mechanisms during interlimb coordination in young and older adults. The project seeks to understand how people coordinate their limbs and the factors which limit and enhance this capacity. This is of critical importance because coordination is a dominant deficit in aging and in patients suffering brain insult and neurodegenerative diseases. Disruption of this capacity compromises individual work productivity, mobility and independence. Proficient motor functioning is an important lifestyle factor as humans age and deficits in coordinated muscle activity will increase the risk of falls which are the leading cause of injury in elderly adults. Identification of changes in brain processes involved in interlimb coordination will allow for the development of strategies to improve motor functions in the aged.Read moreRead less
Nerve cells communicate with each other through nerve processes or neurites. The dysfunction of neurites results in the clinical symptoms of dementia such as cognitive decline. Currently we cannot directly monitor degeneration of neurites in the living brain and therefore it is difficult to determine whether therapeutic agents are protective. My goal is to develop a detection system in the blood that will allow us to monitor these changes during disease progression and therapeutic intervention.
The Future In Our Hands: Screening For Preclinical Alzheimer's Disease By Analysing Hand Movements

Summary
Alzheimer's disease (AD) starts damaging the brain 10-20 years before memory problems begin. By the time of diagnosis, it is hard to treat because the damage is so severe. We need a way to detect AD much earlier. We will develop a simple new computer test to detect early signs of AD by recording and analysing hand movements. Then people can start prevention earlier and scientists can research better treatments to improve people's quality of life and reduce the number of people with dementia.
Age-related changes in brain activation: Indicators of deficiency, maturity, or compensation? It is well established that cognitive and motor performance decline with advancing age. With an aging population, it is of significant socioeconomic importance to facilitate healthy ageing. To promote functional independence in everyday life for as long as possible, a better understanding of brain changes associated with aging is essential. The project will use state-of-the-art neurophysiological techni ....Age-related changes in brain activation: Indicators of deficiency, maturity, or compensation? It is well established that cognitive and motor performance decline with advancing age. With an aging population, it is of significant socioeconomic importance to facilitate healthy ageing. To promote functional independence in everyday life for as long as possible, a better understanding of brain changes associated with aging is essential. The project will use state-of-the-art neurophysiological techniques to examine individual differences in the brain's response to cognitive aging and their association with task performance. Determination of why some individuals show resilience to aging will inform the development of intervention techniques to improve cognitive and motor functions in the aged.Read moreRead less
Improving the diagnosticity of eyewitness memory choices. Eyewitness identification error is common and costly. This project aims to improve the quality of information provided by eyewitnesses, and the ability of police officers and triers of fact (e.g., juries, judges) to evaluate this information. Laboratory investigations will determine how best to test memory and confidence to achieve this aim. A new class of cognitive models will provide a unified account of response accuracy, response time ....Improving the diagnosticity of eyewitness memory choices.

Laboratory investigations will determine how best to test memory and confidence to achieve this aim. A new class of cognitive models will provide a unified account of response accuracy, response time, and confidence, suitable for application to computerized testing scenarios. The models and testing methods validated in the laboratory will be refined for application in eyewitness memory settings, facilitating better evaluation of identification evidence, and potentially reducing wrongful convictions.Read moreRead less
Choice models for learning and memory. Life is filled with familiar choices that often require quick decisions about objects in the environment and the contents of memory. This project examines how we learn to make rapid and accurate choices and how we quickly asses the level of confidence we have in recognition decisions based on our memories.

This project aims to build a digital facility that supports the repatriation of Indigenous human remains. Repatriation contributes to reconciliation and Indigenous healing and wellbeing, and has been the most important agent of change in the relationship between Indigenous peoples, museums and the academy over the past 40 years. Successful repatriation requires and produces research materials diverse in type, geography and accessibility. Within an Indigenous data-governance framework, this project will gather, preserve and make accessible a critical and extensive record of repatriation information worldwide. The project is expected to support repatriation practice and scholarship and improve the opportunities of repatriation for social good.Read moreRead less
