The Analog Mind: Connectionism, Consciousness and Mental Representation. The aim of our project is to explore novel conjectures about the way information is coded and processed in the brain, and the manner in which the brain manufactures consciousness. This work may eventually pay rich dividends by reducing the incidence of mental illnesses, such as schizophrenia, that disturb conscious experience. It may also lead to the development of more powerful forms of computation in artificial neural ne ....The Analog Mind: Connectionism, Consciousness and Mental Representation. The aim of our project is to explore novel conjectures about the way information is coded and processed in the brain, and the manner in which the brain manufactures consciousness. This work may eventually pay rich dividends by reducing the incidence of mental illnesses, such as schizophrenia, that disturb conscious experience. It may also lead to the development of more powerful forms of computation in artificial neural networks. This will have a significant impact on the artificial intelligence industry, with obvious economic benefits for Australia.

Unconscious processing: To what extent, how flexible and how smart? We are unaware of the sophisticated pattern analyses conducted by our perceptual systems that enable us to operate in a complex environment. Less clear is whether unconsciously presented information itself can influence our behaviour or indeed whether unconscious cognition occurs. The proposed studies provide the foundation and structure for a pioneering examination of the extent, flexibility and computational power of unconscio ....Unconscious processing: To what extent, how flexible and how smart? We are unaware of the sophisticated pattern analyses conducted by our perceptual systems that enable us to operate in a complex environment. Less clear is whether unconsciously presented information itself can influence our behaviour or indeed whether unconscious cognition occurs. The proposed studies provide the foundation and structure for a pioneering examination of the extent, flexibility and computational power of unconscious processing at the level of neural response and behaviour. The impact and benefits of the project will be in its contribution to theory with outcomes revealing the boundary conditions governing unconscious cognition and providing a first benchmark for how such conditions might vary across the lifespan.Read moreRead less
Brain mechanisms for coordinating with others through sound. Distinguishing between sounds produced by self and others is critical for interpersonal coordination and communication through speech and music. This project employs a novel dual-brain electrophysiological technique with tagged audio signals to elucidate how the human brain achieves this distinction, and when and why it cannot. Expected outcomes include new knowledge on the neurophysiological mechanisms that support self-other processi ....Brain mechanisms for coordinating with others through sound. Distinguishing between sounds produced by self and others is critical for interpersonal coordination and communication through speech and music. This project employs a novel dual-brain electrophysiological technique with tagged audio signals to elucidate how the human brain achieves this distinction, and when and why it cannot. Expected outcomes include new knowledge on the neurophysiological mechanisms that support self-other processing, and the acoustic conditions and behavioural strategies that facilitate their operation. These outcomes should ultimately have applied benefits for improving interpersonal coordination and social interaction, especially in digital environments and clinical populations with atypical self-other processing.Read moreRead less
Models of Knowledge Restructuring. In a world of rapid change, people must frequently adapt cognitive skills to new technologies. This often requires restructuring of knowledge, from simple initial strategies to increasingly complex ways of mastering the task. This is not always easy and people sometimes resist knowledge restructuring. We present a network model of knowledge restructuring that combines attentional processes with error-driven learning. The model accounts for several existing resu ....Models of Knowledge Restructuring. In a world of rapid change, people must frequently adapt cognitive skills to new technologies. This often requires restructuring of knowledge, from simple initial strategies to increasingly complex ways of mastering the task. This is not always easy and people sometimes resist knowledge restructuring. We present a network model of knowledge restructuring that combines attentional processes with error-driven learning. The model accounts for several existing results and makes predictions that guide the proposed research. Three factors will be examined empirically: (1) the role of directing attention to alternative strategies; (2) the imperfection of existing knowledge; and (3) the complexity of alternative strategies.Read moreRead less

The choices we make define our lives. Despite exciting progress in neuroscience, we still don’t know how the inner workings of the brain give rise to simple decisions. This project brings together experts from diverse domains of computational neuroscience to investigate how our brains turn perceptual information into action. Together, we will develop new methods to track information flow through the brain during the decision making process. By doing so, we will develop a world-leading model of how the brain makes decisions, and also provide the broader scientific community with a set of exciting new tools for studying information processing in the brain.Read moreRead less

Australia is at the forefront of research that is taking brain imaging and interfacing out of the lab and into the field. The technology being developed is spawning applications in areas as diverse as health, education, defense and national security, and will lead to resolution of longstanding theoretical debates as well as enabling new breakthroughs in understanding the biological concomitants of psychological function. This is significant given the push to develop biometrics of psychological function with enhanced sensitivity and specificity in clinical diagnosis, along with defense applications in evaluation of critical personnel and training. It also opens up a range of applications for mental control of remote or prosthetic devices.Read moreRead less
Cortical topology underlying the representation and analysis of visual scenes. When we look around us we seem to perceive our visual surroundings fully, accurately and instantaneously. Despite this strong impression, recent research has revealed that none of this is true. Using virtual environments, brain imaging and neural network simulations, this project aims to discover more about what we do see, which part of our brain stores what we see, and how this storage takes place. The work has the p ....Cortical topology underlying the representation and analysis of visual scenes. When we look around us we seem to perceive our visual surroundings fully, accurately and instantaneously. Despite this strong impression, recent research has revealed that none of this is true. Using virtual environments, brain imaging and neural network simulations, this project aims to discover more about what we do see, which part of our brain stores what we see, and how this storage takes place. The work has the potential to influence the design of danger signs, teleoperated and virtual displays and autonomous machines. It should also help motivate new treatments and rehabilitation regimes for stroke victims.Read moreRead less
