Abstract:
Dyslexic adults have been shown to be slow in processing rapid sequences of stimuli in all sensory modalities. We now demonstrate, by means of an attentional blink task, that the attentional dwell time is prolonged by approximately 30% in dyslexic adults compared with normal readers. Thus a target captures attentional resources for considerably longer time in dyslexics than control subjects. The observed prolongation could significantly contribute to the sluggish temporal processing of dyslexic adults.
