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
Neural metrics for space time and numerosity. What we propose is ground-breaking research. It will increase Australia's international competitiveness is science, expand the knowledge base of brain function and psychology and provide valuable training for research scientists.
Identification and Examination of Visual Cues for Aircraft Glideslope Control. While aviation safety has improved dramatically over the last 50 years, accidents are still more common during landing than any other stage of flight. This project aims to improve our understanding of the way pilots use visual information to land an aircraft. Once our findings have been incorporated into existing training programs, this much-needed information should result in: (i) reduced pilot training time and cost ....Identification and Examination of Visual Cues for Aircraft Glideslope Control. While aviation safety has improved dramatically over the last 50 years, accidents are still more common during landing than any other stage of flight. This project aims to improve our understanding of the way pilots use visual information to land an aircraft. Once our findings have been incorporated into existing training programs, this much-needed information should result in: (i) reduced pilot training time and cost; (ii) increased trainee pilot safety and confidence; and (iii) reduced aircraft maintenance costs. A PhD student, who will be trained in visual perception and aviation, should contribute significantly to future aviation research in this country.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
Organization and Plasticity of Visual Processing in a Miniature Brain. To recognise objects a brain must have an internal representation of most likely object appearance. Two ways in which brains may posses this information include a hard wired template system, and/or the neuroplasticity to learn novel objects. Recent investigations on honeybee vision show that this animal can learn to recognise very difficult objects, although currently we do not know how the miniaturised bee brain manages thes ....Organization and Plasticity of Visual Processing in a Miniature Brain. To recognise objects a brain must have an internal representation of most likely object appearance. Two ways in which brains may posses this information include a hard wired template system, and/or the neuroplasticity to learn novel objects. Recent investigations on honeybee vision show that this animal can learn to recognise very difficult objects, although currently we do not know how the miniaturised bee brain manages these tasks. This project will reveal changes that occur in the processing of visual objects by the bee's brain with increasing experience, with potential applications including robotics or building interfaces between sensors and biological systems.Read moreRead less
Determinants and consequences of conscious visual awareness. Usually salient images can disappear from awareness without corresponding stimulus changes. This project is based on an innovative account linking such disappearances to a functional adaptation which facilitates vision in cluttered environments. Project completion will expand Australia's knowledge base, forge links between junior and senior Australian based investigators and provide excellent training opportunities.

This project is based on an innovative account linking such disappearances to a functional adaptation which facilitates vision in cluttered environments. Project completion will expand Australia's knowledge base, forge links between junior and senior Australian based investigators and provide excellent training opportunities. Publication of research in top-ranking international journals will further promote Australian science abroad. Ultimately, this research will have implications for the design and implementation of artificial visual systems, which must overcome many of the same dilemmas faced by the human visual system in cluttered environments.Read moreRead less
Human time perception: A crossmodal investigation. This research program investigates time perception in humans in the subsecond range. Time perception is a crucial aspect of cognitive functioning but one that is poorly understood. The subsecond scale is particularly relevant because it is the time-frame for crucial tasks such as motor coordination, speech perception and crossmodal integration. This project examines time in an audiovisual context, exploring the cognitive limits of our ability to ....Human time perception: A crossmodal investigation. This research program investigates time perception in humans in the subsecond range. Time perception is a crucial aspect of cognitive functioning but one that is poorly understood. The subsecond scale is particularly relevant because it is the time-frame for crucial tasks such as motor coordination, speech perception and crossmodal integration. This project examines time in an audiovisual context, exploring the cognitive limits of our ability to keep track of time and testing whether time is encoded as a basic feature. These experiments will further our knowledge of time perception and lead to improved models of how the brain encodes time.Read moreRead less
Audio-visual interactions in human perception. How the brain integrates information from different sensory modalities to form coherent perceptions of the external environment is a challenging question in sensory and cognitive neuroscience. Neurophysiologically, sensory interactions have become well documented over the last decade or so. Complementary perceptual research, however, is lacking. This project seeks to redress the imbalance, using audio-visual interactions as a paradigm. Psychophysica ....Audio-visual interactions in human perception. How the brain integrates information from different sensory modalities to form coherent perceptions of the external environment is a challenging question in sensory and cognitive neuroscience. Neurophysiologically, sensory interactions have become well documented over the last decade or so. Complementary perceptual research, however, is lacking. This project seeks to redress the imbalance, using audio-visual interactions as a paradigm. Psychophysical experiments will explore: (i) audio-visual interactions in perception (sound enhancing vision, vision enhancing hearing); (ii) audio-visual interactions in spatial attention. Neurophysiological evidence, plus very recent psychophysical findings of audio-visual interactions, suggest this will be a rich vein of research.Read moreRead less
Characterising and linking intermediate-level processing of pattern, motion and position in human vision? This work will advance basic science by enhancing understanding of human coding of image structure. The aim is to provide a common structure for understanding visual processing of form, motion and position. The work will help lift the international profile of Australian science.

This work will advance basic science by enhancing understanding of human coding of image structure. The aim is to provide a common structure for understanding visual processing of form, motion and position. The work will help lift the international profile of Australian science. Explaining how the primitives for shape perception are extracted will also have consequences of potential economic benefit. One important aspect is the design of displays that allow observers to absorb complex information about rapidly changing situations. This work has the potential to provide information that enables display designers to optimise the efficiency of presentation of pattern and motion information.Read moreRead less
Visual Coding of Motion and Form. Understanding how brains solve the problems of vision may prove crucial in understanding how to build intelligent robots capable of seeing, as well as in developing more sophisticated virtual reality-type computer-based technologies. Moreover, given that a large proportion of our cortex is given over to visual processing, anything we can learn about the operation of the visual system might prove relevant to our understanding of cortical processing in general as ....Visual Coding of Motion and Form. Understanding how brains solve the problems of vision may prove crucial in understanding how to build intelligent robots capable of seeing, as well as in developing more sophisticated virtual reality-type computer-based technologies. Moreover, given that a large proportion of our cortex is given over to visual processing, anything we can learn about the operation of the visual system might prove relevant to our understanding of cortical processing in general as well as bringing us one step closer to an explanation of how activity in our brains gives rise to the experience of conscious perception. This project will directly expand Australia's knowledge-base regarding neural processing in general and visual perception in particular.Read moreRead less
