Welcome to the web pages of the St Paul's Visuomotor Group.

Based in the visuomotor labs of Dr Paul C. Knox in the Institute of Ageing and Chronic Disease’s Department of Eye and Vision Science (located in the new William Henry Duncan building), we have a number of research projects in which we are investigating the control of eye movement and visually guided behaviour in health, ageing and disease, the effect of visual illusions, and the wider impact of visual disability. Details of ongoing projects and publications can be found on the appropriate pages. Recent publications and other information are listed below.

Antisaccade error rate declines with age in Malawian children—but more slowly and to a lesser extent than usually reported. See Knox et al (2016)
