Understanding expertise and race effects in face perception. We are all face experts, with a remarkable ability to distinguish thousands of faces, despite their similarity as visual patterns. We aim to understand the perceptual, cognitive and motivational bases of face expertise, by comparing processing of own-race faces and other-race faces, with which we typically have less expertise. We investigate whether there are deficits in the holistic and configural encoding of other-race faces, whethe ....Understanding expertise and race effects in face perception. We are all face experts, with a remarkable ability to distinguish thousands of faces, despite their similarity as visual patterns. We aim to understand the perceptual, cognitive and motivational bases of face expertise, by comparing processing of own-race faces and other-race faces, with which we typically have less expertise. We investigate whether there are deficits in the holistic and configural encoding of other-race faces, whether these deficits contribute to poorer memory for those faces, whether prejudice amplifies these deficits and whether merely categorizing a face as belonging to another race can trigger deficits in encoding and remembering that face.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.
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 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

Summary
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
The Kids in Communities Study: national investigation of community level effects on children's developmental outcomes. This project (a cross-disciplinary collaboration) will investigate community level factors influencing early childhood developmental outcomes using a mixed methods approach in up to 10 communities across Australia. This will result in a potential set of measures or indicators that reflect communities that are good for children.
Community spirit, social transformation, sustainable partnership: community capacity building for community transformations. This partnership is at the forefront of developments in the provision of community services. The project will contribute to a growing international field of research focused on developing integrated frameworks for measuring community wellbeing. The community capacity building approach will serve as a best practice model for other Australian municipalities.

This partnership is at the forefront of developments in the provision of community services. The project will contribute to a growing international field of research focused on developing integrated frameworks for measuring community wellbeing. The community capacity building approach will serve as a best practice model for other Australian municipalities. The indicators are a tool for engaging communities in making informal decisions and developing shared goals; a policy tool for evidence based planning; and a reporting tool to track and communicate progress towards agreed goals and outcomes. The outcomes will be efficient use of available funding for community services and lower cost of provision of social welfare.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.
