Letencies of stimulus-driven eye movement are shorter in dyslexic subjects

Dorota Bednarek , Adam Tarnowski , Anna Grabowska

Abstract

Eye movements latencies toward peripherally presented stimuli were measured in 10-year-old dyslexic and control children. Dyslexic subjects, previously found to be oversensitive to stimulation of the magnocellular channel, showed reduced latencies as compared to normally reading controls. An attention shifting task was also used which showed no group diVerences in latencies of eye movements. The data are discussed in terms of the hypothesis of magnocellular system alteration and attention dysfunction in dyslexia. Additionally, sex diVerences in eye movement latencies were found and are discussed.
