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 Dreamscape Project aims to discover the neural basis of dreaming. Building on the world’s largest database of sleep electroencephalograms (EEG) and associated dream reports, the project applies cutting-edge analyses of neural activity to resolve why each night, healthy adults alternate between unconscious sleep and vivid dreams. The results promise to shed light on the mystery of dreaming and help locate consciousness in the physical world. Expected outcomes include best-practice guidelines for dream research and a model of open data-sharing for consciousness science. Anticipated benefits include deeper understanding of how and why everyone dreams, the role of dreams in waking life, and their impact on sleep quality and well-being.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.

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.

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

The knowledge and skills developed in the classroom often do not transfer to the workplace or even to other subjects at school. This project aims to evaluate how the transfer of knowledge can be enhanced by prompting students to evaluate and reflect on their performance in specific ways. The project will identify how different students respond to self-evaluation and how self-evaluation can most effectively be designed and applied in the classroom. Newly developed self-evaluation prompts will be implemented in a computerised and adaptive way so that self-evaluation is tailored to a particular student. This project should provide a scalable and cost-effective way to help students apply what they learn in a more flexible and efficient way. Read moreRead less
Thinking about possibilities: Towards a unified cognitive framework. Thoughts about possibilities are fundamental to what makes us human. We routinely imagine what might happen in the future and reflect on how the past could have turned out differently.

Thoughts about possibilities are fundamental to what makes us human. We routinely imagine what might happen in the future and reflect on how the past could have turned out differently. This psychology project aims to establish the circumstances in which children and non-human primates think about alternative possibilities, and to explain how they do it. The project expects to provide new knowledge of cognitive development and evolution, and to distinguish between simple and complex processes for thinking about possibilities. Expected benefits include progress towards a unified cognitive framework that may ultimately be leveraged to help people better reason about possibilities and bring them to fruition.Read moreRead less
