Its members use experimental and computational modelling methods with a diverse range of research tools, including fMRI, haptic feedback control systems and both laboratory-based and perambulatory eye-tracking.
The Laboratory is comprehensively networked: funded links have been created with other 5* Schools across the University (including the School of Electronics and Computer Science, the Institute for Sound and Vibration Research, and Biological Sciences). Close national and international collaborative links exist with key research centres including MPI Tubingen, Tianjin China, UCSD, UMASS, Utrecht, and Oklahoma. Research sponsors include BBSRC, the Department of Homeland Security, the Department of Transport, EPSRC, ESRC, Leverhulme, Microsoft, QinetiQ, the Epilepsy Research Foundation, the British Academy and the Royal Society.
The Visual Cognition Laboratory's research themes range from high-level cognition (for example perceptual expertise & reading and strategic regulation of accuracy in memory) to low-level processes in vision and learning (for example inter-sensory coordination, attentional dynamics, associative learning, and object perception).

Facilities and equipment
The lab is equipped with two Dual Purkinje Image eye trackers, set up to allow simultaneous recording of both eyes. The trackers sample every millisecond, with 1 minarc spatial accuracy. These are interfaced with Cambridge Research Systems shutter goggles, which can be used to present different images to each of the two eyes.
We are currently undertaking research in this lab with adult, child, and dyslexic samples, with both reading and non-reading tasks.
EyeLink 2K Laboratory
The EyeLink2000 lab has both the monocular, tower-mounted camera and the desk-mounted binocular camera available, interfaced with the software provided by SR-Research (Experiment Builder and DataViewer). The system samples at up to 2000 Hz, with spatial accuracy of 0.25°.
Currently, research is being carried out with adult samples on reading and non-reading tasks. The reading research is looking at both English and Chinese readers.
Perambulatory Eye Trackers
We have two perambulatory eye trackers that are designed to allow the participants to move around in the real world whilst their eye movements are being recorded. Each tracker has two cameras, allowing the recording of both the participant's eye movements and the scene in their field of view. These cameras are mounted on the frame of glasses, with the lightweight recording equipment and power supplies carried in a rucksack on the participant's back as they are having their eye movements recorded.
We are planning research with these eye trackers to examine social interactions and scene perception.
The PHANTOM force-feedback device enables users to touch and manipulate virtual objects. In combination with stereo shutter goggles, this equipment is used to investigate how we combine visual and touch information.
We have three mirror stereoscopes available. Stereoscopes allow the presentation of different images to each eye, and are used for research into binocular rivalry, stereopsis, and contrast perception.
