Research interests

Cognitive processing often manifests itself perceptually. Clearly, the sensory system plays a very important role in determining these phenomena. My research is primarily involved in determining visual processing of spatial information and how the sensory system generates a perceptual event. However, some of the most intriguing perceptual phenomena cannot easily be explained by a narrow sensory approach, for example, changes in visual perception that follow the presentation of non-visual information.



Two large research labs in the School of Optometry, access to four clinics where sensory anomalies are regularly encountered, a large variety of high resolution computer generated image-display systems (black and white, and color). Full radiometric and colorimetry measurement facilities.
