要旨

In our everyday lives, humans not only signal their intentions through verbal communication, but also through body movements, for instance when doing sports to inform team mates about one’s own intended actions or to feint members of an opposing team. Here, we study such sensorimotor signaling in order to investigate how communication emerges and on what variables it depends on. In our setup, there are two players with different aims that have partial control in a joint motor task and where one of the two players possesses private information the other player would like to know about. The question then is under what conditions this private information is shared through a signaling process. We manipulated the critical variables given by the costs of signaling and the uncertainty of the ignorant player. We found that the dependency of both players’ strategies on these variables can be modeled successfully by a game-theoretic analysis.
