Professor Jason Mattingley was appointed as Foundation Chair in Cognitive Neuroscience at the University of Queensland in January 2007, a joint appointment between the Queensland Brain Institute and the School of Psychology.
He completed a Bachelor of Science Degree with Honours at Monash University (1988), a Master of Science Degree in Clinical Neuropsychology at the University of Melbourne (1990), and a PhD in Psychology at Monash University (1995). In 1994 he was awarded an NHMRC Neil Hamilton Fairley Post-Doctoral Fellowship, which he took to the University of Cambridge. Here he worked jointly with Professor Jon Driver in the Department of Experimental Psychology and Professor Ian Robertson at the MRC Cognition and Brain Sciences Unit. While in Cambridge he was elected a Fellow of King’s College.
Upon returning to Australia Professor Mattingley was appointed as Senior Research Fellow (later Principal Research Fellow) at the University of Melbourne, where he was Director of the Cognitive Neuroscience Laboratory within the School of Behavioural Science (2000–2006). He was elected a Fellow of the Academy of Social Sciences in Australia in 2007.
In 2012 Professor Mattingley was awarded an Australian Laureate Fellowship by the Australian Research Council.
ICON 2014: Eye Movements and Visual Stability
Humans, like many animals, use eye movements to selectively sample the visual environment, bringing objects of interest onto the fovea for fine-grained analysis. Each time a saccade is made, the retinal image is abruptly displaced. The challenge for the visual system is to maintain perceptual stability in the face of such displacements. One way in which stability might be achieved is by using information about the direction and extent of an impending saccade to update internal representations of the locations and features of objects in the visual world. Neurons at various levels of the visual system, including the midbrain, parietal and prefrontal cortices, alter their responses if an impending saccade will bring a stimulus into their receptive field. Such changes in neural activity provide a potential mechanism for ensuring visual stability across saccades. In this talk I will discuss work in which we have examined the contribution of parietal cortex to visual updating across saccades. I will also present results from a series of psychophysical studies showing that object perception in peripheral vision is enhanced at the goal of an intended saccade, and that presaccadic updating preserves the elementary features of objects at their predicted postsaccadic locations. Our findings suggest a mechanism by which object recognition might be enhanced in the periphery during active search of visually cluttered environments.
