Three experiments were conducted to test the hypothesis if a sniff of others' body odor was comfortable then it could promote their motor mimicry. Participants（ N = 52, 68, 102 respectively） were asked to pair up with a person sitting around and to rate each others' hands on the favorability of their skin, shape warmth, and odor. Then they played a paper-rock-scissors game twelve times. Results showed that the frequency of draws in the game was not influenced by the partners' scent but slightly increased as the difference between the two evaluations of odor likability increased. The findings suggest the body odor can play a certain role in developing an empathic bond.
