A formal signal detection model of eyewitness identification. The project aims to aid in producing better procedures for the collection and assessment of eyewitness identification evidence. In a police line-up, a witness is asked to identify a perpetrator from a group of similar individuals. Applied research has focused on conditions that optimise witness performance but many of the conclusions from this research have been challenged on the basis that they use inappropriate measures of performan ....A formal signal detection model of eyewitness identification. The project aims to aid in producing better procedures for the collection and assessment of eyewitness identification evidence. In a police line-up, a witness is asked to identify a perpetrator from a group of similar individuals. Applied research has focused on conditions that optimise witness performance but many of the conclusions from this research have been challenged on the basis that they use inappropriate measures of performance. Recent work has highlighted the usefulness of analyses based on the theory of signal detection. However, the line-up task does not fit easily within standard signal detection paradigms as it combines two tasks; detection and identification. The project aims to understand how these components work in order to measure witness performance.Read moreRead less

In collaboration with WorkCover NSW, psychologists plan to develop new strategies to promote healthy and safe work environments. The researchers will find how to: best motivate people to engage in healthy work practices and obtain comprehensive and accurate information about the causes of accidents.
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
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.
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
Outcomes of collective action: After the blockade, what next? The project intends to study how collective actors react when conventional or radical collective action succeeds or fails. If a democratic protest rally is ignored by authorities, does support for violence increase? If a turbulent riot attracts favourable media attention and concessions, does this increase the likelihood of future riots or undercut them? This project aims to answer these questions. It plans to test a new, theoreticall ....Outcomes of collective action: After the blockade, what next? The project intends to study how collective actors react when conventional or radical collective action succeeds or fails. If a democratic protest rally is ignored by authorities, does support for violence increase? If a turbulent riot attracts favourable media attention and concessions, does this increase the likelihood of future riots or undercut them? This project aims to answer these questions. It plans to test a new, theoretically integrative model of collective action and the intergroup dynamic, using a mixed-methods approach including experiments, small group research and longitudinal field surveys. Project outcomes may provide an evidence basis for policy-makers' debates about trajectories of radicalisation and deradicalisation, and for recommendations about engagement and negotiation of tactics for activists, political parties, and nongovernment organisations.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.
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.
Optimising the balance between task automation and human manual control. This project aims to discover how best to design automation to maximise performance, while ensuring that operators maintain the task awareness required to manually control previously automated tasks. In environments such as defence and aviation, automating tasks can improve performance, but many accidents have occurred because human operators have not adequately regained manual control when automation has failed. This proje ....Optimising the balance between task automation and human manual control. This project aims to discover how best to design automation to maximise performance, while ensuring that operators maintain the task awareness required to manually control previously automated tasks. In environments such as defence and aviation, automating tasks can improve performance, but many accidents have occurred because human operators have not adequately regained manual control when automation has failed. This project proposes a series of studies using simulations of submarine track management and air traffic control in laboratory and field settings that draw upon psychology and human factors. The project is designed to provide the strategic research that is required to discover how best to adapt the automation currently used in industrial settings.Read moreRead less
