I joined the University of Sheffield in 1983 to begin a PhD with Professors John Frisby and John Mayhew in the Department of Psychology. My PhD investigated human binocular vision and how we fill-in depth information in parts of the visual scene that provide none. This led to an interest in how the visual system uses and integrates depth information from different sources, particularly stereopsis and texture cues. I worked as a postdoc on this problem from 1988 to 1993 on a European grant (ESPRIT) awarded to John Frisby. Here I programmed many stereo stimulus displays using C. During this work it was noticed that there are differences between individuals in how they use different visual cues. Different people can perceive the same visual stimulus differently with these differences remaining consistent across a range of stimuli. This had led to a wider interest in individual differences in visual perception, which I continue to investigate: for example differences between surgeons and non-surgeons, autistic observers and non-autistic, action videogame players and non-players, and the deaf observers and hearing.
As well as the research described above I am also interested in:
- Human stereopsis, particularly the use of vertical disparities to calibrate the visual system
- The use of texture cues by the human visual system
- Visual cue integration
I now mainly use MATLAB and a Cambridge Research Systems VISAGE machine for stimulus control.
From 1993 I have been a lecturer on the BMedSci Orthoptics course. I teach 1st years Transition Skills and 2nd years Visual Perception and Research Methods and 3rd years Data Analysis and Research Writing Skills.
