Summary
Does disconnection in the aging brain cause age-related movement decline? This project aims to use new neurophysiological approaches to understand the causal role of age-related changes in brain network connectivity to the movement control. Brain regions interact through complex and dynamic neural networks to control voluntary movement, but whether age-related changes in network connectivity drive age-related decline in movement control is unknown. This project will provide significant benefits ....Does disconnection in the aging brain cause age-related movement decline? This project aims to use new neurophysiological approaches to understand the causal role of age-related changes in brain network connectivity to the movement control. Brain regions interact through complex and dynamic neural networks to control voluntary movement, but whether age-related changes in network connectivity drive age-related decline in movement control is unknown. This project will provide significant benefits such as the neurophysiological knowledge required to develop targeted interventions to improve movement control in the aging population.Read moreRead less
The emotional face: What determines preferential expression processing. The processing of facial expressions of emotion is essential for successful social functioning. However, we still lack a good understanding of key factors that facilitate or impede the processing of these important social signals. The current project aims to address this knowledge gap by providing a) a more rigorous test of the currently dominant account of expression processing, the evaluative congruence account, and deline ....The emotional face: What determines preferential expression processing. The processing of facial expressions of emotion is essential for successful social functioning. However, we still lack a good understanding of key factors that facilitate or impede the processing of these important social signals. The current project aims to address this knowledge gap by providing a) a more rigorous test of the currently dominant account of expression processing, the evaluative congruence account, and delineating how b) contextual factors and c) person knowledge affect expression processing. The research aims to advance our understanding of facial expression processing, to build international collaborations, and to train the next generation of emotion scientists.Read moreRead less
To focus on pain or not to focus: WHEN is the question. The experience of pain is a ubiquitous experience, and persistent pain is common and causes enormous personal and
societal burden. Anyone who has been in severe pain will understand that pain captures attention, but the role that attention plays in
increasing pain perception is poorly understood. This project will test a new conceptual model that calls for a change in the paradigm underlying research into attention and pain. We will use nov ....To focus on pain or not to focus: WHEN is the question. The experience of pain is a ubiquitous experience, and persistent pain is common and causes enormous personal and
societal burden. Anyone who has been in severe pain will understand that pain captures attention, but the role that attention plays in
increasing pain perception is poorly understood. This project will test a new conceptual model that calls for a change in the paradigm underlying research into attention and pain. We will use novel experimental tasks in virtual reality environments to address
these important gaps in our knowledge. The project will significantly advance our fundamental understanding of
the role of attention in pain perception and pave the way for translational research to reduce the substantial burden pain causes.Read moreRead less
Evaluative learning: do all roads lead to Rome? This project aims to enhance understanding of how likes and dislikes are acquired and changed across a range of different settings. Evaluative learning, the acquisition and change of likes and dislikes, is ubiquitous and occurs in situations that range from trivial to traumatic. However, it is unknown whether evaluative learning in these different situations is mediated by a single or distinct learning mechanisms. Answering this question is critica ....Evaluative learning: do all roads lead to Rome? This project aims to enhance understanding of how likes and dislikes are acquired and changed across a range of different settings. Evaluative learning, the acquisition and change of likes and dislikes, is ubiquitous and occurs in situations that range from trivial to traumatic. However, it is unknown whether evaluative learning in these different situations is mediated by a single or distinct learning mechanisms. Answering this question is critically important for emotion science and the design of effective interventions for anxiety disorders and public health campaigns. The expected outcomes from this project will provide significant benefits, such as creating new knowledge to assist in applied areas ranging from the design of public health messages to the treatment for anxiety.Read moreRead less
The emotional face. The recognition of emotional facial expressions is essential for successful social functioning. This project will determine how information concerning facial expressions is encoded by the human brain, providing potential insight into situations where this process can fail, such as in old age or autism.
Why being lost-in-thought can blind you: the effects of distractor processing on perception. In many cases distraction occurs when we are lost-in-thought, leading us to miss key perceptual events that could prevent accidents. This project will examine this poorly-understood phenomenon, testing how and why this type of distraction occurs, and providing a solid foundation for future basic and applied research in multiple fields.

by using automatically evoked brain responses to examine when new information triggers the brain to update
beliefs about the world. The project will generate new knowledge on the maturity of this process at birth, how it
declines with older age and the brain areas critical to the process. The outcomes will provide insight into how
attentional resources are automatically marshalled when beliefs are challenged, and it will help identify the consequences for learning when a system is immature, or the process breaks down with increasing age.Read moreRead less
The role of early testosterone and brain laterality in language development. The aim of the project is to provide key insights into how foetal hormone exposure and early brain growth support child language. The specialisation of the left cerebral hemisphere for language function is considered critical to supporting the complexity of human language. There is evidence of sex differences in patterns of brain specialisation, which has led to popular but unsubstantiated hypotheses linking prenatal te ....The role of early testosterone and brain laterality in language development. The aim of the project is to provide key insights into how foetal hormone exposure and early brain growth support child language. The specialisation of the left cerebral hemisphere for language function is considered critical to supporting the complexity of human language. There is evidence of sex differences in patterns of brain specialisation, which has led to popular but unsubstantiated hypotheses linking prenatal testosterone and language development. The project aims to explore this by using innovative neuroimaging, endocrine and genetic techniques to track neurodevelopment longitudinally from prenatal life to three years of age. An important aspect of the project is the anticipated refinement of innovative methods for measuring early human development.Read moreRead less
How brain oscillations influence our behaviour. This project aims to reveal how sudden, intense stimuli impair or facilitate concurrent actions. Startling sounds can disrupt the execution of movements and distract attention from vital events in the environment, with potential disastrous consequences when handling complex equipment such as airplanes, cars and trucks, or surgical instruments. This project will combine classic experimental and novel neuro-modulatory techniques with the measurement ....How brain oscillations influence our behaviour. This project aims to reveal how sudden, intense stimuli impair or facilitate concurrent actions. Startling sounds can disrupt the execution of movements and distract attention from vital events in the environment, with potential disastrous consequences when handling complex equipment such as airplanes, cars and trucks, or surgical instruments. This project will combine classic experimental and novel neuro-modulatory techniques with the measurement of oscillatory brain activity. Expect outcomes will inform theories of cognitive function and the design of interventions to reduce the negative effects of sudden, distracting events.Read moreRead less
The extinction of human fear. Excessive fear negatively impacts the lives of many Australians - so how can we increase the effectiveness of exposure based treatments to reduce human fear? The present basic research will investigate the process thought to underlie exposure-based treatments, extinction of human fear learning, in order to answer this applied question.
