Members are interested in the fundamental workings of the normal human visual and auditory systems. The primary aim is to understand how sensory data is picked up and encoded to build meaningful representations of the outside world upon which we can act. Two central aspects of this are: (1) understanding the processes of perception—the subjective experience of seeing and hearing—and (2) understanding the processes of visual and auditory performance—the limits to what can be done in audio and visual tasks. Research techniques include psychophysics, neuroimaging and computational modelling.
