Fluctuation in Spatial Ability Scores during the Menstrual Cycle.
Moody, M. Suzanne
Whether or not fluctuations in spatial ability as measured by S. G. Vandenberg's Mental Rotations Test occur during the menstrual cycle was studied with 133 female students from 9 undergraduate educational psychology and nursing classes. For comparison, 28 male students also took the test. Scores from 55 females fell into the relevant menstrual phases during 3 repeated testings held approximately 7 days apart. A mixed analysis of variance procedure using G. Keppel's method for removal of practice effects indicated that female performance on the spatial test was significantly higher during the menstrual phase (days 2-7) than during the luteal phase (days 16-28). The performance of contraceptive pill users was not significantly different from the performance of nonusers. These findings confirm the findings of I. Silverman and K. Phillips (1993) in an area where previous results have been inconsistent. The 28 males performed significantly higher than the females during the initial testing, but males' scores obtained during this initial testing were not significantly different from scores obtained from contraceptive pill users in the menstrual phase but were significantly higher than scores obtained from pill users in the luteal phase.
