Abstract
Ehara et al.(1984) and Yamazaki & Ehara (1993) found following facts in their conversation analysis.
1) Many silences are observed in men's conversation. 2) Few silences are observed in women's conversation. 3) Man often interrupts woman's talk, and woman plays the role of listener in conversation between a man and a woman. From these facts, Ehara et al. (1984) concluded that social power exited between men and women. However, Ehara et al. (1984) could not specify the mechanism that produced such social power. This paper analyses this mechanism by using evolutionary game theory. As a result, this paper clarifies that self-defensive emotion realizes social power between men and woman, insists that tolerance to negative others enables equity relation between men and woman.
