The model has been formalised by three-levelled partial temporal models, covering both the material and mental processes and their relations. The generic process model has been designed, implemented and used to simulate different types of interaction between verbal and non-verbal communication processes: a non-verbal communication process that adds and modifies content to a verbal communication process, but also provides a protocol for the (control of the) verbal communication process. With respect to the communication protocol stimulus-response behaviour and deliberate behaviour have been modelled and simulated.
