THE CONTRIBUTION OF VISUOSPATIAL WORKING-MEMORY TO IMPAIRMENTS IN FACIAL PROCESSING AND ARITHMETIC IN TURNER-SYNDROME

Turner syndrome (TS) is a disorder in which females are born with eith er a single X chromosome or one partial second chromosome. The disorde r has associated cognitive deficits and neuropsychological impairments . We examine the extent to which two of these impairments (facial proc essing and arithmetic) are determined by deficits in visuospatial work ing memory. When contrasted with normal age matched controls, the 9 gi rls in the TS group performed more poorly on both arithmetic and facia l processing tests. Moreover, their scores were related to the extent to which they were sensitive to visuospatial information during a test of working memory.
