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.
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
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.
Maturation of the brain and the development of cognitive abilities. This project aims to develop techniques for measuring the growing brain. We will use these techniques to determine how the growing brain influences a child's intellectual ability and to answer an important question - do areas of the brain mature at the same or different rates and what influence does that have on the development of specific abilities such as language and reasoning? An answer to this question will make an import ....Maturation of the brain and the development of cognitive abilities. This project aims to develop techniques for measuring the growing brain. We will use these techniques to determine how the growing brain influences a child's intellectual ability and to answer an important question - do areas of the brain mature at the same or different rates and what influence does that have on the development of specific abilities such as language and reasoning? An answer to this question will make an important contribution to our theoretical understanding of developmental disorders. Moreover, given the influence of intellectual development on life prospects, it is important to understand how early brain development impacts on a child's ability to learn.Read moreRead less
The emotional face: Effects on orienting, visual search, and categorization. The processing of facial expressions of emotion is essential for successful social functioning however our understanding of how these important signals are processed and of the factors which may impede appropriate processing is lacking. Using a range of converging methodologies drawn from neuroscience, social, and cognitive psychology, this project aims to advance our understanding of the processing of the expressions o ....The emotional face: Effects on orienting, visual search, and categorization. The processing of facial expressions of emotion is essential for successful social functioning however our understanding of how these important signals are processed and of the factors which may impede appropriate processing is lacking. Using a range of converging methodologies drawn from neuroscience, social, and cognitive psychology, this project aims to advance our understanding of the processing of the expressions of two central social emotions, happiness and anger, by delineating the conditions that support or limit it in the general population. This research aims to provide an invaluable knowledge base for subsequent applied research into deficits of emotional expression processing such as occur in autism, anxiety, or old age.Read moreRead less
Single and dual process models of recognition memory: Reconciliation of behavioural, electrophysiological, and neuroimaging data. Advanced brain scanning technologies are increasingly used to study human memory. As well as being important for our basic understanding of memory, they also tell us how memory is affected by normal development, ageing, disease, and injury. Unfortunately, because these technologies are so new, a gap has opened up between our psychological understanding of memory and t ....Single and dual process models of recognition memory: Reconciliation of behavioural, electrophysiological, and neuroimaging data. Advanced brain scanning technologies are increasingly used to study human memory. As well as being important for our basic understanding of memory, they also tell us how memory is affected by normal development, ageing, disease, and injury. Unfortunately, because these technologies are so new, a gap has opened up between our psychological understanding of memory and the physiological events measured by the scanning technologies. This has created a problem for how we should interpret the results that are found. The present project aims to close this gap by applying new research methodologies and theoretical insights based on our previous research.Read moreRead less
Why does face identification ability improve during childhood? Accurate face identification is crucial to social functioning and is supported by face-specific visual and neural mechanisms. Performance on tests of face identification continues to improve from preschool ages until well into adolescence. What drives this improvement? This project compares two current theories to determine whether face-specific development or more general cognitive and perceptual development drives this improvement. ....Why does face identification ability improve during childhood? Accurate face identification is crucial to social functioning and is supported by face-specific visual and neural mechanisms. Performance on tests of face identification continues to improve from preschool ages until well into adolescence. What drives this improvement? This project compares two current theories to determine whether face-specific development or more general cognitive and perceptual development drives this improvement. The project will employ a powerful and novel approach, using individual differences and a longitudinal design that will provide new insights into the source of developmental change in face identification skills during childhood. This project also examines how development breaks down by studying Congenital Prosopagnosia (face-blindness).Read moreRead less
Perceptual and psychosocial factors associated with individual differences in face identity and face expression processing. What makes one person better or worse than another at recognising faces, or the emotions displayed in those faces? This project examines which aspects of visual perception contribute to these abilities, and their associations with problems such as debilitating social anxiety and young children's anti-social behaviour.
Attentional and conditioning mechanisms that mediate overcoming anxiety. Anxiety is a common emotion for most Australians that can cause substantial costs for individuals and society. This project uses dominant psychological models to identify critical mechanisms that are believed to predict capacity for, and change in, anxiety. Outcomes substantially advance knowledge about how humans overcome anxiety.
