Spatial and temporal processing in patients with Turner's syndrome

Thirteen females with Turner's syndrome were examined for spatial abilitles and serial processing, and their performance was compared with that of normal females matched by age, intellignece, and socioeconomic class. Patients with Turners's syndrome performed significantly poorer on tests of spatial ability than controls, but only on spatial tests requiring the integration of isolated elements as synthetic wholes or the remembering of spatial configurations which could not be verbally mediated. Patients also performed less well than controls on tasks of serial processing when the tasks could not be mediated verbally. 2t was concluded that patients with Turner's syndrome may have a selective deficit in cortical functions that are lateralized to the right cerebral hemisphere.
