Summary
The dynamics of object representations in the human brain. The human brain's ability to effortlessly recognise and categorise objects enables effective behavioural responses in complex everyday environments. Despite the apparent efficiency of this process, it is still unknown how the brain solves object recognition. This project capitalises on cutting-edge advances in artificial intelligence and neuroscience to resolve the spatiotemporal dynamics of object processing in the human brain.

The human brain's ability to effortlessly recognise and categorise objects enables effective behavioural responses in complex everyday environments. Despite the apparent efficiency of this process, it is still unknown how the brain solves object recognition. This project capitalises on cutting-edge advances in artificial intelligence and neuroscience to resolve the spatiotemporal dynamics of object processing in the human brain. The outcomes will be a step change in our understanding of the nature and development of the multi-dimensional space underpinning neural object processing. This will ultimately facilitate the diagnosis and treatment of brain disorders across the lifespan and accelerate the development of intelligent machines.Read moreRead less
Human Scheduling of Perceptual Tasks. This project aims to develop a novel approach for synthesising how people prioritise information with theories of attention and decision making. Characterising inefficient scheduling in the tradeoff between the difficulty and the cost/benefit of different subtasks will allow the development of a formal computional model that generalises statistical models of rank order data to a theory of the timing of scheduling decisions and task completions. Outcomes incl ....Human Scheduling of Perceptual Tasks. This project aims to develop a novel approach for synthesising how people prioritise information with theories of attention and decision making. Characterising inefficient scheduling in the tradeoff between the difficulty and the cost/benefit of different subtasks will allow the development of a formal computional model that generalises statistical models of rank order data to a theory of the timing of scheduling decisions and task completions. Outcomes include benchmark data from a novel paradigm for studying perceptual decisions and behavior and a model which can explain and predict human scheduling. This project aims to benefit industry by allowing for the simulation of information prioritisation by human agents in complex environments.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
Dealing with distraction: understanding recovery after interruption. Interruptions impair cognitive performance but modern environments have normalised distractions in our workplaces, homes, schools and cars. Daily tragedies occur because people are unaware of their attentional capacity limits. This Fellowship explores the consequences of interruption in moving displays using cutting-edge methods to determine how the brain holds information over an interruption and the process of attentional rec ....Dealing with distraction: understanding recovery after interruption. Interruptions impair cognitive performance but modern environments have normalised distractions in our workplaces, homes, schools and cars. Daily tragedies occur because people are unaware of their attentional capacity limits. This Fellowship explores the consequences of interruption in moving displays using cutting-edge methods to determine how the brain holds information over an interruption and the process of attentional recovery. It includes translational work determining effective ways to raise awareness of attention limits and guide policy. The outcomes will advance knowledge of the mechanisms of recovery from interruption, raise awareness of capacity limits beyond academia, and guide policy to improve safety.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
Understanding Growth in Emotion Regulatory Flexibility in Emerging Adults. Emerging adults (ages 18-25) are now facing unparalleled social and technological change and the on-going effects of the COVID-19 pandemic. Such demands can be overwhelming and undermine engagement with education and employment, with serious impacts for the individual and society. At the same time, our novel model proposes that the diverse daily adult-like stressors that characterise emerging adulthood can also drive grow ....Understanding Growth in Emotion Regulatory Flexibility in Emerging Adults. Emerging adults (ages 18-25) are now facing unparalleled social and technological change and the on-going effects of the COVID-19 pandemic. Such demands can be overwhelming and undermine engagement with education and employment, with serious impacts for the individual and society. At the same time, our novel model proposes that the diverse daily adult-like stressors that characterise emerging adulthood can also drive growth in flexible emotion regulation when combined with reflection on, and insight into, their own coping processes. Our research expands scientific knowledge by taking the first steps to uncover why some emerging adults increase their ability to flexibly regulate their emotions over this period, whereas others fail to do so.Read moreRead less
From me to you and beyond: understanding socially-induced nocebo effects. Nocebo effects – when negative expectancies trigger adverse outcomes – cause enormous personal and societal harm. We have made great progress understanding how instruction and conditioning contribute to nocebo effects. Yet, the role of social learning – what we learn by observing others – has received surprisingly little attention despite its relevance to many prominent societal-level nocebo effects.

Nocebo effects – when negative expectancies trigger adverse outcomes – cause enormous personal and societal harm. We have made great progress understanding how instruction and conditioning contribute to nocebo effects. Yet, the role of social learning – what we learn by observing others – has received surprisingly little attention despite its relevance to many prominent societal-level nocebo effects. The current project uses novel experimental methods to understand how social learning contributes to nocebo effects and which strategies inhibit these effects. The results will significantly advance scientific understanding of socially-induced nocebo effects and pave the way for translational research to reduce the substantial harm they cause.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
