Two-week test-retest of the WAIS-R and WMS-R subtests, the purdue pegboard, trailmaking, and the mental rotation test in women

This study investigated test-retest over a e-week period in several common cognitive tests. These tests included some of the WAIS-R and WMS-R subtests, the Purdue Pegboard, Trailmaking, and the Mental Rotation Test (MRT). The sample consisted of 20 women with varied educational level and age. The subjects were administered the tests twice with a P-week interval. Practice effects and test-retest reliability were examined. A total of II out of 14 of these tests showed a significant difference in score between testing sessions, with the MRT and Logical Memory subtest of the WMS-R, Trailmaking, and the Arithmetic and Picture Completion demonstrating the largest practice effect. These results have direct application in studies that require short test-retest periods, such as those examining drug effects and menstrual cycle variation in women.
