Neurochemical predictors of cognition and the impact of brain stimulation. This project aims to determine how neurochemical equilibrium between excitation and inhibition (E/I balance), across the brain, is associated with executive function and how this balance is influenced by non-invasive brain stimulation. Brain stimulation shows immense promise for enhancing executive function in applied settings, but the neurochemical basis for this is unknown.

This project aims to determine how neurochemical equilibrium between excitation and inhibition (E/I balance), across the brain, is associated with executive function and how this balance is influenced by non-invasive brain stimulation. Brain stimulation shows immense promise for enhancing executive function in applied settings, but the neurochemical basis for this is unknown. Using advanced imaging and stimulation techniques, the project aims to provide comprehensive insights into the causal relationship between stimulation, E/I balance and executive function. Outcomes and benefits include identifying neurochemical characteristics that determine stimulation efficacy and informing the design of protocols for applied use.Read moreRead less

Investigating how visual imagery influences cognition. This project will characterise the role visual imagery plays in other cognitive functions, namely visual working memory and attention. This will be done by studying two special populations that have extreme forms of visual imagery: aphantasia and synaesthesia. This work will develop innovative psychophysics and physiological techniques to identify different cognitive strategies used to solve visual working memory and attention tasks.

This project will characterise the role visual imagery plays in other cognitive functions, namely visual working memory and attention. This will be done by studying two special populations that have extreme forms of visual imagery: aphantasia and synaesthesia. This work will develop innovative psychophysics and physiological techniques to identify different cognitive strategies used to solve visual working memory and attention tasks. Further magnetoencephalography (MEG) decoding approaches will be used to compare and contrast the neural signatures of voluntary and involuntary visual imagery, working memory, and attention. This work will help us understand why some individuals have better imaginations, memory, and attention than others. Read moreRead less

The cognitive science of farsighted deliberation. Many fundamental decisions in life require us to deliberate about sooner versus later consequences. This cognitive psychology project aims to determine how the capacities that enable people to think about the future (prospection) and reflect on their own thinking (metacognition) influence how they manage such decisions. By using innovative methods, this project is expected to advance our understanding of future-oriented cognition across the lifes ....The cognitive science of farsighted deliberation. Many fundamental decisions in life require us to deliberate about sooner versus later consequences. This cognitive psychology project aims to determine how the capacities that enable people to think about the future (prospection) and reflect on their own thinking (metacognition) influence how they manage such decisions. By using innovative methods, this project is expected to advance our understanding of future-oriented cognition across the lifespan. Expected outcomes include new knowledge about how people deliberate through important everyday decisions. This should provide significant benefits by laying the foundation for improving effective choices about the future.Read moreRead less
Understanding the role of mental imagery in cognition and behaviour. This project aims to develop objective physiological methods to measure mental imagery, uncover its brain mechanisms using neuroimaging and show how it biases cognition. It has long been suspected that mental imagery biases cognition, visual working memory and perception. However, showing this has been difficult due to a lack of measurement techniques. Here this is overcome by developing novel assay technologies and applying th ....Understanding the role of mental imagery in cognition and behaviour. This project aims to develop objective physiological methods to measure mental imagery, uncover its brain mechanisms using neuroimaging and show how it biases cognition. It has long been suspected that mental imagery biases cognition, visual working memory and perception. However, showing this has been difficult due to a lack of measurement techniques. Here this is overcome by developing novel assay technologies and applying them to the extremes of imagery, Aphantasia (no imagery) and Hyperphantasia (strong and vivid imagery). Expected outcomes include new measurement tools for generations of scientists, understanding the brain mechanisms of imagery and showing how our cognition (memory, risk, investing) is biased by mental imagery.

Towards a cognitive process model of how attention and choice interact. Before making any decision, we must gather information on what options are available. This process may influence the choices we make: if we do not notice an option, we will not choose it even if it would have been valuable. This project aims to examine how prior experience can produce attentional biases that influence decisions, and will develop a new computational model of this interaction of attention and choice as an outc ....Towards a cognitive process model of how attention and choice interact. Before making any decision, we must gather information on what options are available. This process may influence the choices we make: if we do not notice an option, we will not choose it even if it would have been valuable. This project aims to examine how prior experience can produce attentional biases that influence decisions, and will develop a new computational model of this interaction of attention and choice as an outcome. This new knowledge will enhance the world-class status of Australian cognitive psychology. Moreover, it should provide significant benefits through improving our ability to predict and shape behaviour, and shedding light on the role of biases in healthy cognition and in the context of compulsive behaviours.Read moreRead less

This proposal aims to understand and make predictions about which real world images -- specifically living things, objects, and human faces -- that people will remember remember via an integration of cognitive models of memory and machine learning techniques. Computer vision models and similarity scaling techniques will be used to produce psychological representations of the images. These representations will then be integrated with cognitive models of memory, which predict that images are more likely to be recognized if they are similar to each of the representations in memory. Large scale memory and similarity rating datasets will be used to develop and test the model.Read moreRead less

This project aims to address the pressing problem of why Australian secondary school children have been declining in literacy. To do so is crucial, since adolescence is a period when strong literacy is critical for knowledge acquisition and preparation for adult life. The project will use a range of theoretically-informed methods to scrutinise cognitive processes in adolescent reading, as well as identify interactions between reading progress and socio-emotional functioning and motivation. Expected outcomes will be the first comprehensive account of secondary school reading acquisition and new insights into how to optimise progress. These will inform research, policy, and reading instruction practice, to the benefit of Australia's children.Read moreRead less
