| Description: In a study that challenged popular stereotypes about premenstrual syndrome, college women and men recorded their moods daily for 70 days without knowing the purpose of the research. At the end of the study, the women recalled that their moods had been more negative pre-menstrually than during the rest of the month (green line), but their daily diaries showed otherwise (blue line). Both sexes experienced only moderate mood changes, and there were no significant differences between women and men at any time of the month (McFarlane, Martin, & Williams, 1988).
