The task consisted of detecting a ''Q'' target among ''O'' distractors in variable numbers and the reverse. The Ž. method used a paradigm based on the stimulus onset asynchrony SOA specifically designed to measure the visual processing time between the visual array and a mask. A different visual search pattern was observed in each group. The hearing subjects showed an Ž. asymmetrical visual search pattern parallel versus serial processing respectively for ''Q'' and ''O'' targets. In contrast, the deaf subjects Ž. showed a symmetrical search pattern parallel processing in both experimental conditions. In a visual task selectively supported by central vision, visual processes of the congenitally deaf are more efficient when the task involves the contribution of serial processes.
