Apparently enhanced visual information processing in female fragile X carriers: preliminary findings.

Abstract

Eighteen normally intelligent adult female fragile X carriers were tested with the "de Sonneville Visual Attention Tasks," a computer-based set of reaction-time experiments, in order to assess different aspects of their attention capacity. The subject group was compared with a group of 48 adults, who were not known to be fragile X carriers. We publish preliminary results of this study. These show that the fragile X carriers have significantly faster reaction times at a substantial number of the tests. This suggests that normally intelligent female fragile X carriers might process simple visual information, such as the targets offered in these reaction time experiments, at a faster rate than control women.
