Moving to be seen: a comprehensive analysis of movement-based signal design. Papers on visual motion processing and animal signal design regularly feature in major journals, and the programs of international conferences. We can thus be confident that theoretical advances will attract international attention. We will develop further state-of-the-art methods in motion analysis, with our overall approach likely to serve as a framework for future research programs, although our techniques will have ....Moving to be seen: a comprehensive analysis of movement-based signal design. Papers on visual motion processing and animal signal design regularly feature in major journals, and the programs of international conferences. We can thus be confident that theoretical advances will attract international attention. We will develop further state-of-the-art methods in motion analysis, with our overall approach likely to serve as a framework for future research programs, although our techniques will have applications outside of biology. In addition, we will learn much about the social behaviour of a group of native reptiles about which relatively little is known. Research on the social behaviour of animals is readily comprehended by non-specialists and plays an important role in attracting young people to careers in science.Read moreRead less

In the international setting, visual psychophysics is playing a major role in this development. The present project will help maintain Australia's international competitiveness in this rapidly growing field. Also, given how important being able to accurately perceive motion is to our ability to safely interact with the world, there are a number of potential applied benefits of the proposed research. These benefits range from areas like road safety to clinical neuropsychology.Read moreRead less
Perceiving and tracking moving objects. Processing and tracking moving objects poses challenges for human perception. To succeed, visual processing must accumulate analyses of the object from its different positions. Perceptual experiments will reveal human limits and yield insights into the underlying mechanisms, providing a basis for understanding object tracking in tasks like driving.
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.
Suction pipette measurements of mammalian rod photoreceptor recovery following intense bleaching exposures. The aim of this project is to discover the events and processes that prevent retinal photoreceptors from recovering instantaneously following the cessation of exposure to extremely bright illumination. Recordings will be made from single rod photoreceptors cells isolated from the mammalian retina. The work will uncover the relative roles of the 'photoproducts' created when rhodopsin abso ....Suction pipette measurements of mammalian rod photoreceptor recovery following intense bleaching exposures. The aim of this project is to discover the events and processes that prevent retinal photoreceptors from recovering instantaneously following the cessation of exposure to extremely bright illumination. Recordings will be made from single rod photoreceptors cells isolated from the mammalian retina. The work will uncover the relative roles of the 'photoproducts' created when rhodopsin absorbs light: e.g. intermediates such as metarhodopsin and opsin. The molecular knowledge obtained will help us to understand why it is that the visual system recovers so slowly after the eye has experienced very intense light.Read moreRead less
Face recognition: Properties and origins of whole-face processing. Humans identify other individuals almost entirely by their faces. Correspondingly, research has demonstrated a "special" style of cognitive processing that is unique to faces (at least in ordinary adults). The present project will address two major theoretical issues: (1) the exact nature of the special processing for faces, and (2) the extent to which it is innate, or learned. New progress in understanding these issues will be m ....Face recognition: Properties and origins of whole-face processing. Humans identify other individuals almost entirely by their faces. Correspondingly, research has demonstrated a "special" style of cognitive processing that is unique to faces (at least in ordinary adults). The present project will address two major theoretical issues: (1) the exact nature of the special processing for faces, and (2) the extent to which it is innate, or learned. New progress in understanding these issues will be made using a series of novel experimental techniques. These techniques isolate the specific contribution of the face recognition system, independent of contributions from object recognition, and from early visual processing.Read moreRead less
Special cognitive processing for faces: Expertise effects, and links to neural mechanisms. Humans identify other individuals primarily by their faces. Evidence from cognitive psychology indicates a special 'whole-face' (as opposed to part-based) style of processing for upright faces. This project will provide new insights into two long-standing issues about the origin of special face processing: (1) whether it derives from generic expert recognition processes or has some face-specific innate co ....Special cognitive processing for faces: Expertise effects, and links to neural mechanisms. Humans identify other individuals primarily by their faces. Evidence from cognitive psychology indicates a special 'whole-face' (as opposed to part-based) style of processing for upright faces. This project will provide new insights into two long-standing issues about the origin of special face processing: (1) whether it derives from generic expert recognition processes or has some face-specific innate component; and (2) the extent to which it can be distinguished from part-based processing at the neural level using both functional brain imaging (fMRI) and adaptation to distorted faces.Read moreRead less
