Numerous findings suggest that menstrual cycle related variations in sex hormones influence cognitive processes (Kimura, 2002), psychomotor abilities (Mead and Hampson, 1997) and mood (Campton and Levine, 1997). Although different studies in this area have not came up with the same results, high levels of progesterone in luteal phase have been suggested to reduce functional cerebral asymmetry (Hausmann et al., 2008). Given that cerebral asymmetry indeed changes across menstrual cycle, it seems likely that differences in performance of Fitt's tapping tasks (FTT’s) with right and left hand would be less pronounced in luteal phase with regard to phases of lower sex hormones level. Additionally, in phases of higher sex hormones levels better efficacy can be expected. Thus, the aim of this study was to examine changes of efficacy in performance of FTT’s across menstrual cycle. Twenty-four normally cycling women with a mean age of 21.7 years participated in this study. They were tested four times, during menstrual, late folicular, luteal and premenstrual phase. Subjects performed series of FTT’s, difficulty range from one to four bits. The working time for every task was one minute. Twelve subjects started performing the tasks with right, and other twelve with left hand. All subjects used right as their dominant hand. Results suggest a decrease in performance of FTT’s during luteal phase of a menstrual cycle, with tendency of decrement in function of task difficulty. Additionally, results indicate an increase of efficacy in menstrual phase, when levels of estradiol and progesterone were low. Furthermore, the results did not show a decrease cerebral asymmetry during luteal phase, as expected. Generally speaking, these results suggest that efficacy in performance of FTT’s shows similar pattern of changes as in tasks which males usually solve better than females (i.e. spatial tasks).
