Implicit transmission of embodied culture. Is a culturally diverse, yet socially integrated community possible? In multicultural societies such as Australia, this is a pressing and significant question. To form and maintain a vibrant and prosperous community in the face of globalization, it is essential to understand the fundamental processes by which cultures are formed and transformed in everyday social activities. This project examines one such process, implicit cultural transmission, propose ....Implicit transmission of embodied culture. Is a culturally diverse, yet socially integrated community possible? In multicultural societies such as Australia, this is a pressing and significant question. To form and maintain a vibrant and prosperous community in the face of globalization, it is essential to understand the fundamental processes by which cultures are formed and transformed in everyday social activities. This project examines one such process, implicit cultural transmission, proposed to function in the nonconscious transmission of cultural information. Understanding the dynamics of this subtle, yet pervasive, mode of cultural influence is central to a full appreciation of how one's own culture and those of others' integrate and flourish.Read moreRead less
Behaviour of large networks of neurons in a functioning organ: a realistic computer-based model of the enteric nervous system. The organisation of the gut nervous system is well understood, but how nerve cells cooperate to control gut movements and secretions are matters of conjecture. We will test these conjectures by simulating the behaviour of the gut nervous system using an anatomically and physiologically realistic computer model to predict the way the gut responds to specific stimuli and t ....Behaviour of large networks of neurons in a functioning organ: a realistic computer-based model of the enteric nervous system. The organisation of the gut nervous system is well understood, but how nerve cells cooperate to control gut movements and secretions are matters of conjecture. We will test these conjectures by simulating the behaviour of the gut nervous system using an anatomically and physiologically realistic computer model to predict the way the gut responds to specific stimuli and test these predictions using novel methods for recording gut movements and nervous activity. This will provide the first complete description of how a mammalian nervous system generates complex behaviours and will provide substantial pointers to how other nervous systems achieve similar tasks.Read moreRead less
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

Summary
Perception and Action in Auditory Scenes (PAAS): Neural, Behavioural, Computational and Mechanical Systems. Auditory scenes are temporal and ephemeral yet pervasively influence human life. How humans negotiate such scenes has not been solved, a fact highlighted by attempts to build machines to respond to speech, warnings etc., in real-world situations with room reverberation, different talkers, and background noise. No one discipline can solve such problems. In this network outstanding researche ....Perception and Action in Auditory Scenes (PAAS): Neural, Behavioural, Computational and Mechanical Systems. Auditory scenes are temporal and ephemeral yet pervasively influence human life. How humans negotiate such scenes has not been solved, a fact highlighted by attempts to build machines to respond to speech, warnings etc., in real-world situations with room reverberation, different talkers, and background noise. No one discipline can solve such problems. In this network outstanding researchers from physical, medical, human, and social sciences with interests in speech, music and audition will provide insights into how humans and machines localize, recognize, interpret and produce auditory events, and advance frontier technologies, e.g., automatic speech recognition, hearing prostheses, auditory monitoring/warning systems.Read moreRead less
A Scalable Theory of Behavior Composition for Practical Engineering Models of Human Performance. Minimizing human error and maximizing human performance is a major design goal in safety critical systems. The development of methods for affordable human performance modeling has widespread applicability for evaluating user-system interfaces. The compositional method explored here has been shown to make accurate predictions reduce model development time by an order of magnitude. Large safety critica ....A Scalable Theory of Behavior Composition for Practical Engineering Models of Human Performance. Minimizing human error and maximizing human performance is a major design goal in safety critical systems. The development of methods for affordable human performance modeling has widespread applicability for evaluating user-system interfaces. The compositional method explored here has been shown to make accurate predictions reduce model development time by an order of magnitude. Large safety critical applications, such as military or air traffic control systems, would benefit greatly. The proposed work tests whether the compositional methods will scale to more complex domains. The work will be coordinated with Australian industry, academia, and government research efforts.Read moreRead less

This project develops a pidgin language for use in computer games and models the way human users exploit such languages. It has implications also for computer assisted collaborative work and other educational or entertainment interactive environments like computer games. By developing mini-languages for games environments we can dramatically simplify the speech recognition problem and make recognition robust across different speech cultures and backgrounds. We use protocol analysis and markup techniques for modelling dialogues between human player and reactive agents in computer games.Read moreRead less

Also, it will provide new insights into the mechanisms regulating human cognition and mental dysfunctions.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
