“…The importance of controlling time effects is evident in some repeated measures design studies, which analyze cognitive performance and cerebral asymmetries during the menstrual cycle (McKeever, 1995). Gordon, Corbin, and Lee (1986) demonstrated that women who started three testings of verbal and spatial tasks at their follicular phase outperformed women who started during menses. Mead and Hampson (1996) observed a pronounced left visual half field increase in accuracy and speed from the first to the second session, when subjects started in the midluteal phase.…”

The aim of the present study was to analyze whether task repetitions which are an inevitable part of repeated measures designs might induce performance alterations specific for gender and hemisphere. Male and female subjects conducted twice a lexical decision, a polygon recognition, and a face discrimination task as a visual half field paradigm with the two experimental sessions repeated by 2 weeks. The results show that only in female subjects can a session effect for the lexical decision and the polygon recognition task be demonstrated which is hemisphere specific. Thus, repeated measures designs seem to have a gender-and hemisphere-specific effects of their own which could confound with other variables under study.

“…Direct hormone measurements are a prerequisite for menstrual cycle research, as previous studies had to exclude large numbers of participants (up to 46%, Gordon et al, 1986) because hormone assays revealed that participants were not in the expected cycle phase. As a result, if some participants were tested just before or after the expected peak in estradiol and/or progesterone levels, the variability in the degree of lateralisation would be greater across participants.…”

AbstractNatural fluctuations of sex hormones during the menstrual cycle have been shown to modulate language lateralisation. Using the dichotic listening (DL) paradigm, a wellestablished measurement of language lateralisation, several studies revealed that the left hemispheric language dominance was stronger when levels of estradiol were high. A recent study (Hjelmervik et al., 2012) showed, however, that high levels of follicular estradiol increased lateralisation only in a condition that required participants to cognitively control (top-down) the stimulus-driven (bottom-up) response. This finding suggested that sex hormones modulate lateralisation only if cognitive control demands are high. The present study investigated language lateralisation in 73 normally cycling women under three attention conditions that differed in cognitive control demands. Saliva estradiol and progesterone levels were determined by luminescence immunoassays. Women were allocated to a high or low estradiol group. The results showed a reduced language lateralisation when estradiol and progesterone levels were high. The effect was independent of the attention condition indicating that estradiol marginally affected cognitive control. The findings might suggest that high levels of estradiol especially reduce the stimulus-driven (bottom-up) aspect of lateralisation rather than top-down cognitive control.

“…Cycle phase can be estimated by counting backward to the first day of menstruation. Although this counting method has been used legitimately in some previous research, the approach has been associated with an error rate of 15 [34] to 50% [13]. Confirmation of expected hormone concentrations by radioimmunoassay (RIA) is critical for validating menstrual phase, because accuracy in determining menstrual phase is likely a major factor contributing to incongruent results across previous studies.…”

Implicit memory varies across the menstrual cycle: estrogen effects in young women

2002

View full text Add to dashboard Cite

Evidence that ovarian steroid hormones such as estrogen and progesterone affect cognition comes from studies of memory in older women receiving estrogen replacement therapy and studies of sexually dimorphic skills in young women across the menstrual cycle. Sixteen women (ages 18-28) completed tests of memory (implicit category exemplar generation, category-cued recall, implicit fragmented object identification) and sexually dimorphic skills (fine motor coordination, verbal fluency, mental rotations) at the early follicular (low estrogen and progesterone) and midluteal (high estrogen and progesterone) phases of the menstrual cycle. Performance on category exemplar generation, a test of conceptual implicit memory, was better at the midluteal than the follicular phase. In contrast, performance on a test of explicit memory, category-cued recall, did not vary across the menstrual cycle. At Session 1, women in the follicular phase performed better on the fragmented object identification task than did those in the midluteal phase. This unexpected finding suggests that high levels of ovarian hormones might inhibit perceptual object priming. Results confirmed previous reports of decreased mental rotations and improved motor skills and fluency in the midluteal phase. Estradiol levels correlated positively with verbal fluency and negatively with mental rotations and perceptual priming, which suggest that estrogen, and not progesterone, was responsible for the observed changes in cognition. Mood did not vary across the cycle phases. Overall, the findings suggest that estrogen may facilitate the automatic activation of verbal representations in memory.
