ABSTRACT: This study identifies eye movement differences amongst dyslexic and non-dyslexic groups during varying visual reading stimuli.
Four ocular metrics are investigated: fixation duration, regression count, blink
count and blink duration. In this study, 24 participants were divided into two groups dyslexic
(n = 11) and non-dyslexic (n = 13) to read an electronic reading stimulus under
different visual typographic conditions. A t-test analysis of each group was conducted
for each ocular metric. Significant differences were observed amongst three of the
four ocular metrics: fixation duration (p 0.001), regression count (p p p
