Ostracism and Aggression. Ostracism has been implicated in school shootings (e.g., Columbine) and other violent or anti-social episodes (e.g., Port Arthur shootings). Some argue that ostracism drives individuals toward joining violent extremist groups. Research, however, is mixed: sometimes targets of ostracism correct their behaviors to be more socially acceptable; whereas other times they react with aggression. This research program will investigate the conditions under which ostracism either ....Ostracism and Aggression. Ostracism has been implicated in school shootings (e.g., Columbine) and other violent or anti-social episodes (e.g., Port Arthur shootings). Some argue that ostracism drives individuals toward joining violent extremist groups. Research, however, is mixed: sometimes targets of ostracism correct their behaviors to be more socially acceptable; whereas other times they react with aggression. This research program will investigate the conditions under which ostracism either leads to paths of either pro-social or aggressive reactions. A new virtual reality paradigm will be developed to provide stronger manipulations of ostracism and to assist in discovering the crucial conditions responsible for these paths.Read moreRead less
Neural mechanisms for human form perception. This project aims to determine if there is a single cortical mechanism underlying the human ability to discriminate and recognise objects. It has been speculated that different classes of objects, or forms require different processes. Demonstrating a single process would be a significant advance towards understanding the neural mechanisms giving rise to our ability to segment visual fields into meaningful objects and background. This research provides ....Neural mechanisms for human form perception. This project aims to determine if there is a single cortical mechanism underlying the human ability to discriminate and recognise objects. It has been speculated that different classes of objects, or forms require different processes. Demonstrating a single process would be a significant advance towards understanding the neural mechanisms giving rise to our ability to segment visual fields into meaningful objects and background. This research provides a means for testing models of the neural interactions thought to be generating human form perception and will help us discover how the visual cortex converts raw sensory input into object and form perception.Read moreRead less
A cross-linguistic investigation of lexical stress using corpus analyses, behavioural testing and computational modelling. Some languages exhibit variable patterns of emphasis or 'lexical stress' across words ('ZEbra' v 'girAFFE'). This research will provide a more precise understanding of the role of lexical stress in language processing. This will assist educators/clinicians working with normally developing children and those with developmental delays as well as educators/students in second-l ....A cross-linguistic investigation of lexical stress using corpus analyses, behavioural testing and computational modelling. Some languages exhibit variable patterns of emphasis or 'lexical stress' across words ('ZEbra' v 'girAFFE'). This research will provide a more precise understanding of the role of lexical stress in language processing. This will assist educators/clinicians working with normally developing children and those with developmental delays as well as educators/students in second-language learning. It will also lead to improved automatic speech recognition/synthesis - used in commercial applications such as phone banking, edutainment/epistemic computer games and communication devices (speech-to-text dictation systems for those with limited mobility and text-to-speech systems for those unable to speak). Undertaken in collaboration with a high-profile research lab in the UK this project will maintain Australia's competitive edge in cognitive science.Read moreRead less
