Emotional Induction Study of Video in Menstrual Cycle through ECG Signal

The purpose of this study is to investigate the effects of different phases of the menstrual cycle (follicular phase and luteal phase) on emotion induction of video through ECG signal. Firstly, the ECG data of twenty subjects were acquired when they were watching positive, negative or neutral videos in follicular phase and luteal phase, respectively. Then, the RR interval series were obtained from the ECG data. Finally, some statistical, such as the mean, the standard deviation, the first and second differences between consecutive RR intervals, and the root mean square and Krawchouk moment features were extracted from the RR interval series to evaluate the effects of different phases of the menstrual cycle on emotion induction by using extreme learning machine. The results shown that women were more irritated and more likely to induce negative emotions during the luteal phase.
