This paper gives an overview of the literature on the visuo-perceptual and visuo-attentional deficits of dyslexic children. The hypothesis that visuo-attentional problems cooccur with dyslexia was assessed through a task of search for a target among distractors. Serial-attentional visual processing was required in one task condition (search for 0 among Qs) whereas the other condition involved parallel/ automatic processing (search for Q among 0 s) . Ten dyslexic subjects constituted the experimental group. Their performance was compared to that of 20 non-dyslexic children, 10 matched for chronological age and 10 for reading age. The performance of dyslexic subjects was similar to that of children matched for chronological age in the parallel/ automatic condition. In contrast, their performance differed by an increased search slope from that of the two control groups in the serial/ attentional condition. These results suggest the existence of visuo-attentional deficits in dyslexic children.
