Summary
There is increasing scientific and public interest in the role of diet and lifestyle in the prevention of cognitive decline. Easy to follow, modifiable lifestyle factors, such as diet, that improve cognitive function and reduce cognitive decline are attractive to middle aged and older Australians. We hypothesise that a Mediterranean diet pattern, consumed over 6 months, will improve cognitive function and psychological wellbeing in older men and women.
The development of predictive brain function in preschool children. This project aims to track developmental changes in brain activity and connectivity in typically developing three-to-six year-old children. The preschool years are a time of huge change in children's cognitive abilities, but little is known of the corresponding changes in brain function. This work will use child-optimised magnetoencephalography to test the hypothesis that early cognitive development is characterised by refinemen ....The development of predictive brain function in preschool children. This project aims to track developmental changes in brain activity and connectivity in typically developing three-to-six year-old children. The preschool years are a time of huge change in children's cognitive abilities, but little is known of the corresponding changes in brain function. This work will use child-optimised magnetoencephalography to test the hypothesis that early cognitive development is characterised by refinement of the brain's innate ability to generate predictions about the sensory environment. The resulting insights could improve understanding of neurodevelopmental disorders such as autism.Read moreRead less
Dynamics of word recognition: new insight from the reach-to-touch paradigm. This project will introduce a new behavioural reach-to-touch paradigm for studying basic cognitive processes such as word recognition. The advantage of this paradigm is that it is able to measure cognitive processes moment-by-moment as they unfold over time. This will provide new insights into the temporal dynamics of basic cognitive processing.
Risky Futures: Toward a Computational Process Model of Risky Inter-Temporal Choice. A lot is known about people’s preferences. People like their rewards now. Most would prefer $10 today than $20 in one month. Risk is also unattractive; a certain $10 is more attractive than a 50 per cent chance of receiving $25. Surprisingly, much less is known about the interaction between delay and risk. That is, relatively little is known about whether people prefer $10 now, or a 50 per cent chance of $50 in ....Risky Futures: Toward a Computational Process Model of Risky Inter-Temporal Choice. A lot is known about people’s preferences. People like their rewards now. Most would prefer $10 today than $20 in one month. Risk is also unattractive; a certain $10 is more attractive than a 50 per cent chance of receiving $25. Surprisingly, much less is known about the interaction between delay and risk. That is, relatively little is known about whether people prefer $10 now, or a 50 per cent chance of $50 in one month. This project will use a combination of experiments and cognitive modelling to examine all three types of choice. The outcome will be a novel computational model that will elucidate the complex interaction between delay and risk, thereby answering an enduring question in the literature: are risk and delay psychologically equivalent?Read moreRead less
Learning how people read: Models, brains, big data and maths. Aims: This project aims to understand how people read. We will use novel mathematical methods, experimentation, brain imaging and computational modelling to adjudicate between model predictions.
Significance: This project expects to develop methods to understand and test important aspects of reading.
Expected outcomes: Expected outcomes are the development of novel methods for understanding complex models and the collection of data t ....Learning how people read: Models, brains, big data and maths. Aims: This project aims to understand how people read. We will use novel mathematical methods, experimentation, brain imaging and computational modelling to adjudicate between model predictions.
Significance: This project expects to develop methods to understand and test important aspects of reading.
Expected outcomes: Expected outcomes are the development of novel methods for understanding complex models and the collection of data that can extend and falsify current models of reading.
Benefits: These developments will significantly increase our understanding of how people read and what causes dyslexia. This work will also provide new ways to evaluate complex computational psychological models.Read moreRead less
How do people make uncertain predictions? Exemplar-based and category-based approaches to inductive inference. This project is an innovative experimental and field study of how people reason under uncertainty. The project will broaden our understanding of human reasoning and enhance the reputation of Australian cognitive science.
How are beliefs altered by data? Robust Bayesian models for human inductive learning. This project applies state of the art mathematical models to study how people think and reason, and how we can make good guesses about the future. The goal is to understand how the human mind can operate so effectively in real environments, when even the most powerful computers struggle to handle the complexities of everyday learning problems.
Are Healthcare Interventions Exacerbating Alzheimer's Disease (AHEAD)

Summary
The AHEAD Study will assess the impact of anaesthesia and surgery on cognitive function in patients with Mild Cognitive Impairment or mild Alzheimer's Disease. Such effects have not been established. With an ageing population being increasingly exposed to healthcare procedures requiring anaesthesia or sedation, any negative impact needs to be identified so that therapeutic decisions may be informed and future research appropriately targeted.
Getting back on track after the unexpected happens: decision making in predictable and unpredictable environments. This project intends to examine how the brain decides where to look next with our eyes, a decision made approximately three times every second. Understanding how the normal brain makes decisions will in turn help us to understand what happens when things go wrong in diseases like dementia and Parkinson's disease.
Cracking the orthographic code: investigating early perceptual processes in reading. Current understanding of how human readers decode a string of letters into known words is inadequate. This project advances understanding of this early reading process, by combining computational modelling, behavioural and brain imaging approaches.
