Research Interests (key words only)

Psychophysical investigations of human sensory perception.


After a three year period working in Optometric Practice he returned to Bradford and competed his PhD thesis in 2006. The title was 'Audiovisual Perceptual Interaction in Humans'.

Following an 18 month post doctoral research assistant he was appointed as a lecturer within the Department of Optometry.

Study History

James Heron is an optometrist who graduated from the University of Bradford in 1998.

Following a pre-registration year at Gartnavel General Hospital he joined the College of Optometrists in 1999.

Research Areas

His research interests centre around psychophysical investigations of human sensory perception. The question of how the human brain constructs a representation of multisensory space and time is of particular interest together with issues surrounding the role of adaptation to spatiotemporal discrepancies in our environment.
