Dr. Mark Harwood

Lecturer

Psychology

    Mark teaches on the BSc and MSc programmes in research methods and Cognitive Psychology. He did his undergraduate degree at the University of Edinburgh, before completing his Developmental Psychology PhD at UCL, and going on to postdoctoral research in Cognitive and Experimental Psychology in New York.



    Overview

    Vision is a highly active process: what we see is strongly determined by where we direct our eyes, and we move our eyes consciously or unconsciously several times a second. Eye movements provide an excellent 'window to the brain', revealing principles of how the brain makes decisions, learns from mistakes, and generates our visual perception of the world.

    My research is quantitative, precisely measuring things like the speed, reaction time and accuracy of eye movements as people look at moving or stationary parts of the visual scene.  From these, one can infer the underlying neural processes; or infer pathologies in these measures in developmental and neurodegenerative diseases.
