Paolo, Anthony M.; Axelrod, Bradley N.; Troster, Alexander I. – Assessment, 1996
Eighty-seven normal older people were administered the Wisconsin Sorting Test on two occasions averaging over a year apart. There were average retest gains of 5 to 7 standard score points. The standard error of prediction, standard error of difference, and abnormal test-retest discrepancy scores were calculated for clinical use. (SLD)
