An exploration of interference control and post-error adjustment in the context of the menstrual cycle: A study on women’s performance in an online version of the flanker task

Steroid hormones are frequently highlighted as an important modulator of women’s susceptibility for developing mood and anxiety disorders. One of the often-considered influences is the effect of estradiol on the dopaminergic activity in the prefrontal cortex. Given this association it was investigated if natural levels of estradiol might affect women’s executive functions. The focus of measurement was the participant’s performance on the flanker task. It was hypothesised that women in a menstrual cycle phase marked by high estradiol show enhanced interference control and post-error adjustment. The study was conducted as an observational, natural group design and executed in an online format. Self-reports on the menstrual cycle were used for an approximation of the women’s current estradiol levels based on which two groups of women, either high or low in estradiol, were created. Main comparisons were made between 29 naturally cycling women in total and 48 men. The outcomes suggest...Show moreSteroid hormones are frequently highlighted as an important modulator of women’s susceptibility for developing mood and anxiety disorders.

Main comparisons were made between 29 naturally cycling women in total and 48 men. The outcomes suggest that the cycle phase of women and the assumed levels of estradiol may not have influenced the processes of interference control or post-error adjustment. To interpret the obtained results, the measured constructs, interference control, error monitoring, and the menstrual cycle are discussed, and possible uncontrolled variables outlined. Future research is needed to further explore women’s executive processes and related neural correlates in the context of the menstrual cycle. Research in this field may provide better understanding of possible influences on women’s cognitive and emotional circuits in the brain, which will help to achieve a clearer picture of women’s psychological wellbeing throughout their life span.Show less
