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. Explaining how the primitives for shape perception are extracted will also have consequences of potential economic ....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. 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
How the human visual system uses pattern information to organize motion. This project is an investigation into human vision, a priority area for ARC. Its aim is to discover how photons from moving objects leave traces in the human visual system that assist it to determine the path of local motion and the structure of global motion. Its theoretical significance is that it will lead to substantial revisions of current models of human visual processing. Its practical significance is that it will pr ....How the human visual system uses pattern information to organize motion. This project is an investigation into human vision, a priority area for ARC. Its aim is to discover how photons from moving objects leave traces in the human visual system that assist it to determine the path of local motion and the structure of global motion. Its theoretical significance is that it will lead to substantial revisions of current models of human visual processing. Its practical significance is that it will provide a theoretical basis for the design of display systems that are more effective in conveying information about motion to human observers and eliminate errors inherent in existing systems.Read moreRead less
Applying the Psychologist's Microelectrode to High-Level Vision: What face aftereffects can tell us about face processing. Aftereffects, the psychologist's microelectrode, can show how our visual experience relates to neural activity. In the well-known waterfall illusion, neurons coding downwards motion become fatigued while watching a waterfall, making stationary objects on the riverbank appear to move upwards. Viewing a face for a few seconds can have a similar effect, causing a previously ....Applying the Psychologist's Microelectrode to High-Level Vision: What face aftereffects can tell us about face processing. Aftereffects, the psychologist's microelectrode, can show how our visual experience relates to neural activity. In the well-known waterfall illusion, neurons coding downwards motion become fatigued while watching a waterfall, making stationary objects on the riverbank appear to move upwards. Viewing a face for a few seconds can have a similar effect, causing a previously neutral or average face to take on the opposite identity. Here we explore what this and other face afterffects can tell us about how faces are coded in high level vision.Read moreRead less
How human vision separately determines object and scene motion. This project aims to enhance understanding of how people process visual scenes containing multiple moving objects of interest. The project intends to measure human visual performance to determine how the brain processes multiple motion signals simultaneously. Expected outcomes include an increased understanding of how we are able to use an evolving visual scene to distinguish between changes due to self-motion and those due to the m ....How human vision separately determines object and scene motion. This project aims to enhance understanding of how people process visual scenes containing multiple moving objects of interest. The project intends to measure human visual performance to determine how the brain processes multiple motion signals simultaneously. Expected outcomes include an increased understanding of how we are able to use an evolving visual scene to distinguish between changes due to self-motion and those due to the motion of multiple moving objects such as crowded city footpaths and busy roads. The results will improve our understanding of failures to see moving objects in challenging viewing conditions (for example, high density traffic), and inform work in the design of autonomous driving and augmented reality display systems.Read moreRead less

Tackling facial prejudice. This project aims to investigate individual differences in facial prejudice, a powerful psychological bias whereby people rely on inaccurate first impressions to guide key decisions, such as whom to trust. Utilising recent advances in electrophysiology, the project will develop a new neural marker of individual differences in facial impressions that lead to prejudice. The project expects to lead to insights into the link between visual perception and social behaviour, ....Tackling facial prejudice. This project aims to investigate individual differences in facial prejudice, a powerful psychological bias whereby people rely on inaccurate first impressions to guide key decisions, such as whom to trust. Utilising recent advances in electrophysiology, the project will develop a new neural marker of individual differences in facial impressions that lead to prejudice. The project expects to lead to insights into the link between visual perception and social behaviour, and to develop strategies to reduce facial prejudice given the pervasive influence it has on everyday life.Read moreRead less
Form and motion interactions in human motion perception. Vision works efficiently to detect the motion of both ourselves and other objects by combining motion and pattern information. This project will determine how the visual system achieves this and also create a detailed model that will be directly applicable to areas ranging from clinical neuropsychology to the analysis and design of visual displays.

Summary
Sensory prediction: the role of forward modelling in visual processing. Because of motion, patterns of light received by our eyes contain inherent structure across space and time, a fact which the brain exploits to form predictions about future patterns of visual input. This project will determine how these predictions are constructed from motion signals system and what role they play in visual processing.
Decoding the process of holistic shape encoding in the human visual system. The visual coding of shape is an important stage in object perception and yet we currently do not fully understand how shapes are encoded by the brain. This project aims to discover the cues used by the visual system to holistically represent shape and to explore the functional interactions between the cortical regions responsible for this task.
Coding of Shape in Human Vision. This project aims to improve understanding of how the shape of objects is encoded in human vision. Knowing the shape of an object is critical for interacting with it appropriately. This project aims to study the human ability to convert local patches of light into a coherent shape description and will determine how a recently identified cue, representing the distribution of features in a shape, is used by the visual system to perform this task. The resulting desc ....Coding of Shape in Human Vision. This project aims to improve understanding of how the shape of objects is encoded in human vision. Knowing the shape of an object is critical for interacting with it appropriately. This project aims to study the human ability to convert local patches of light into a coherent shape description and will determine how a recently identified cue, representing the distribution of features in a shape, is used by the visual system to perform this task. The resulting description of shape coding, based on human vision, will help design methods for both efficiently encoding images in artificial vision systems and for creating images of objects for display.Read moreRead less
