Contextual modulation in high-level vision. This project aims to understand the nature and mechanisms of spatial contextual modulation and the relationship between spatial and temporal context. Contextual modulation refers to the sometimes profound changes in the appearance of the visual image caused by interactions across space and time. Little work has been done to examine whether spatial context effects exist for high-level attributes of objects, and socially relevant stimuli such as heads an ....Contextual modulation in high-level vision. This project aims to understand the nature and mechanisms of spatial contextual modulation and the relationship between spatial and temporal context. Contextual modulation refers to the sometimes profound changes in the appearance of the visual image caused by interactions across space and time. Little work has been done to examine whether spatial context effects exist for high-level attributes of objects, and socially relevant stimuli such as heads and bodies. This project expects to provide new knowledge regarding the way that contextual modulation is mediated by interactions within the normal human visual system. This will provide significant societal benefits as contextual interactions in sensory processing can have profound consequences for our perceptual experience.Read moreRead less
Extracting meaning from motion. This project aims to understand how the human visual system uses motion signals to detect the presence of other people and nonhuman animals. This question links vision science to social experience, and will be addressed using rigorous methods for studying human vision combined with 3D graphical modelling of interactive motion. The expected outcomes include an improved theoretical understanding of how rich, social information is extracted from motion signals in the ....Extracting meaning from motion. This project aims to understand how the human visual system uses motion signals to detect the presence of other people and nonhuman animals. This question links vision science to social experience, and will be addressed using rigorous methods for studying human vision combined with 3D graphical modelling of interactive motion. The expected outcomes include an improved theoretical understanding of how rich, social information is extracted from motion signals in the brain and the introduction of new techniques for testing an individual's social perception. This is expected to provide the knowledge and methodological tools to progress research in clinical neuroscience, computer vision, and interactive robotics.Read moreRead less

The results of the research will provide clear direction to road authorities and driver training providers as to effective training strategies to improve young driver training, and ultimately improve road safety with this vulnerable population.Read moreRead less
From sensation to aesthetic appreciation. This project aims to understand the perceptual foundations of aesthetics. The experience of beauty is among the most compelling aspects of our interaction with the world but understanding aesthetic appreciation is difficult, because aesthetic experience varies between individuals, and is assumed to be influenced by culture, context and taste. In contrast, this project offers an account of aesthetic experience which connects the aesthetic object, the perc ....From sensation to aesthetic appreciation. This project aims to understand the perceptual foundations of aesthetics. The experience of beauty is among the most compelling aspects of our interaction with the world but understanding aesthetic appreciation is difficult, because aesthetic experience varies between individuals, and is assumed to be influenced by culture, context and taste. In contrast, this project offers an account of aesthetic experience which connects the aesthetic object, the perceptual processing of its properties and the resulting affective responses. Outcomes from this project will have potential applications in creative settings from design of pleasing visual surroundings to user experience and advertising.Read moreRead less
Multisensory perception in active observers. Perception and action are usually studied separately, often under limited, non-ecological conditions. Recent evidence shows both functions are intrinsically linked and mutually influence each other. This project exploits new technologies to study dynamic perception in free-moving observers in real and virtual multisensory environments. The project will establish the mechanisms underlying the perception/action link and reveal how perceptual stability i ....Multisensory perception in active observers. Perception and action are usually studied separately, often under limited, non-ecological conditions. Recent evidence shows both functions are intrinsically linked and mutually influence each other. This project exploits new technologies to study dynamic perception in free-moving observers in real and virtual multisensory environments. The project will establish the mechanisms underlying the perception/action link and reveal how perceptual stability is achieved despite dynamic input that changes with action. It will generate new understanding of how the brain integrates its twin functions of perceiving the multisensory world and acting upon it, and will generate useful knowledge for virtual, remote and robotic applications.Read moreRead less

Eyes on the prize: Investigating attentional economics. We spend our lives surrounded by stimuli relating to reward and risk (adverts, games, social media etc). Recent research suggests that learning about reward and risk influences our attention, often despite our best efforts. This project will build on recently developed procedures using eye-tracking to investigate how learning about reward and risk modulates what we pay attention to, and what we ignore.

We spend our lives surrounded by stimuli relating to reward and risk (adverts, games, social media etc). Recent research suggests that learning about reward and risk influences our attention, often despite our best efforts. This project will build on recently developed procedures using eye-tracking to investigate how learning about reward and risk modulates what we pay attention to, and what we ignore. Findings will be used to develop computational models of ‘attentional economics’ that account for, and predict, when we will be distracted by reward- and risk-related stimuli. This research will enhance the world-class status of Australian cognitive psychology, and will shed light on processes implicated in addiction and related behaviours.Read moreRead less
