Abstract

Considering nonverbal communication and its complexity, four problems are addressed which focus on the dynamics of nonverbal communication. (1) How much of the complexity of nonverbal communication is due to the amount of expressions following cultural rules (e. g. conventions) and the expressions of the agents´ states through their signaling systems? (2) Nonverbal behaviour can be regarded as time-varying multi-scaled multimodal configurations of magnitudes. It is natural to ask for scaling laws. (3) Furthermore, the dynamics of the configurations just mentioned is of interest. (4) Why are verbal expressions more conventional than nonverbal ones? The discussion of the four problems suggests that signal-based explanations of nonverbal behaviour and communication are incommensurable with convention-based explanations.
