Future production modelling will probably involve cognition at all stages. It is too early to say just what a simulation based on modelling cognitive processing would look like. I have suggested that if human cognitive processing can be described as sets of reasoned decision taking processes, a linguistics model suitable for simulation might be constructed which includes stages of reasoned decision taking as a means of selecting information from the knowledge bases. Reasoned decision taking in the simulation One of the ideas to emerge from considering the form of a simulation model involves deciding on what basis knowledge can be retrieved. The knowledge bases contain optional rules which account for a wide range of variability.
Selection involves retrieving and evaluating information from several different sources.
I have been looking at devices capable of reasoned decision taking, and proposed such a device for simulating speech production. 14 Transformation of an action prescription following reasoned decision taking. Input A is from the main algorithm which encodes concepts as sounds. An action prescription is a generalized specification of what is to be done, but not how to achieve it. The device works toward achieving a goal , which is to provide another action prescription.
