Fourteen female subjects were tested during the menstrual (days 1–4), follicular (days 6–12), luteal (days 17–21), and premenstrual (days 23–27) phases of their menstrual cycles. Of the tests used (arm‐hand steadiness, galvanic skin response to an auditory stimulus, reaction time ‐ simple and choice, time estimation, and digit‐symbol substitution), only arm‐hand steadiness showed statistically significant fluctuations over the course of the cycle. Daily self‐ratings of various symptoms and moods showed no significant changes when the appropriate statistical techniques were used; parametric techniques suggested fluctuations in reports of pain, bloatedness, hunger, hours of sleep, and pressure of immediate academic work.
