Active Vision: Asking the Right Questions about Human Vision

Professor Iain Gilchrist PhD

The AVA 2007 Annual Meeting took place in April at the University of Bradford and focused on Active and Passive Vision. Prof. Iain Gilchrist kicked off proceedings by taking this years G. J. Burton Memorial Lecture. Iain is a Professor of Neuropsychology and Head of the Department of Experimental Psychology at the University of Bristol and Honorary Neuropsychologist at North Bristol NHS Trust. His lecture, which highlights the importance of saccadic eye movement study in the field of vision research, is available here with slides and audio.

Abstract

Iain highlights how it is vital that we study saccadic eye movement when researching vision. He demonstrates how many in the Vision Science community ignore two basic properties of vision, that are intrinsically connected; (1) the eyes move (2) visual sensitivity is highly heterogeneous across visual space. By discussing the arguments for ignoring these two aspects he shows us how in fact there is no argument. From this, we can understand how the types of questions we ask and experiments we do should change, and that a complete and useful model of vision has to include saccades and fixations.

Professor Iain Gilchrist took his first degree in Psychology at the University of Durham (1989-92) and then went on to study for his PhD at the University of Birmingham (1992-95). After this, Iain worked as a Research Associate at the University of Durham (1995-98) before joining the Department of Experimental Psychology at the University of Bristol as Lecturer in Neuropsychology in 1998 and becoming reader in Neuropsychology in 2002.

 

He is an Honorary Neuropsychologist in North Bristol NHS Trust; A member of: The Applied Vision Association; The Experimental Psychology Society; The British Ocular Motor Group and an Associate Member, Centre for Vision and Visual Cognition, University of Durham.

Research Interests

Iain’s research is concerned with the link between vision and action. Vision provides information so that we can interact with the world and these interactions involve motor systems such as eye, arm, head and whole body movements. One major focus of his work has been to understand how and why we move our eyes; Eye movements are interesting  because the movement itself radically changes the nature of the visual input.

He has also been working with others to look at other visually guided actions such as drawing, copying and foraging. In order to understand the processes they have been testing both patients and unimpaired individuals and are involved in building a biologically inspired robot.
