Abstract

We tested the hypothesis that the differences in performance between developmental dyslexics and controls on visual tasks are specific for the detection of dynamic stimuli. We found that dyslexics were less sensitive than controls to coherent motion in dynamic random dot displays. However, their sensitivity to control measures of static visual form coherence was not significantly different from that of controls. This dissociation of dyslexics' performance on measure that are suggested to tap the sensitivity of different extrastriate visual areas provides evidence for an impairment specific tothe detection of dynamic properties of global stimuli, perhaps resulting from selective deficits in dorsal stream functions.
