How human vision separately determines object and scene motion. This project aims to enhance understanding of how people process visual scenes containing multiple moving objects of interest. The project intends to measure human visual performance to determine how the brain processes multiple motion signals simultaneously. Expected outcomes include an increased understanding of how we are able to use an evolving visual scene to distinguish between changes due to self-motion and those due to the m ....How human vision separately determines object and scene motion. This project aims to enhance understanding of how people process visual scenes containing multiple moving objects of interest. The project intends to measure human visual performance to determine how the brain processes multiple motion signals simultaneously. Expected outcomes include an increased understanding of how we are able to use an evolving visual scene to distinguish between changes due to self-motion and those due to the motion of multiple moving objects such as crowded city footpaths and busy roads. The results will improve our understanding of failures to see moving objects in challenging viewing conditions (for example, high density traffic), and inform work in the design of autonomous driving and augmented reality display systems.Read moreRead less

Moving from assumptions to new learning. . Moving from assumptions to new learning. The project aims to investigate the processes that drive new learning
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

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
Reading facial expressions from real and virtual humans. This project aims to advance understanding of human emotional communication and improve human rapport with the virtual humans and avatars that are rapidly infiltrating our social world. Using two unique stimulus sets - naturalistic human expressions and highly realistic virtual faces - together with powerful genetic, experimental, and individual differences designs, the project expects to answer previously intractable questions in emotion ....Reading facial expressions from real and virtual humans. This project aims to advance understanding of human emotional communication and improve human rapport with the virtual humans and avatars that are rapidly infiltrating our social world. Using two unique stimulus sets - naturalistic human expressions and highly realistic virtual faces - together with powerful genetic, experimental, and individual differences designs, the project expects to answer previously intractable questions in emotion science, as well as deliver tangible outcomes, such as new psychological tests to better understand human social connection. This should provide significant benefits, by improving emotion communication and offering a new perspective on how artificial intelligence can best serve human social needs.

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
Multidimensional autistic traits and attention in healthy adults. This project aims to develop a new, comprehensive measure of six major dimensions of autistic traits in healthy adults. High levels of autistic traits are associated with atypical patterns of attention in healthy adults. However autistic traits are multidimensional, with some dimensions weakly correlated, and few studies have assessed sensory sensitivity, a key trait dimension. This project will investigate the specific relationsh ....Multidimensional autistic traits and attention in healthy adults. This project aims to develop a new, comprehensive measure of six major dimensions of autistic traits in healthy adults. High levels of autistic traits are associated with atypical patterns of attention in healthy adults. However autistic traits are multidimensional, with some dimensions weakly correlated, and few studies have assessed sensory sensitivity, a key trait dimension. This project will investigate the specific relationships of autistic traits to key attentional phenomena including left-visual-field bias, attention to detail at the expense of integrative processing, and the attraction of attention to emotional stimuli. Linking behavioural and cognitive features of autistic traits will inform models of the development of autism.Read moreRead less

Species redundancy in response to multiple disturbances. This project aims to elucidate how the context within which disturbances occur affects food web linkages and how these map to responses in ecosystem function. There is a critical need to test the common assumption in environmental management that high biodiversity makes ecosystems resilient to disturbances.

This project aims to elucidate how the context within which disturbances occur affects food web linkages and how these map to responses in ecosystem function. There is a critical need to test the common assumption in environmental management that high biodiversity makes ecosystems resilient to disturbances. Studies that merely observe biodiversity change after disturbance cannot identify ecological processes connecting high diversity and ecosystem function, making experiments that manipulate identical disturbances in ecosystems with different biodiversity essential. This project will use field experiments that manipulate disturbances in streams replicated in low and high biodiversity regions and across gradients of chronic background stress to show how biodiversity sustains functional ecosystems, and how much diversity can be lost before ecosystems collapse.Read moreRead less
