MODELS OF COGNITION - PROCEDURAL PROTOTYPES AND CONTEXTUAL CONTROL

It is argued that the modelling of cognition should attempt to reprodu ce key phenomena rather than replicate the mechanisms of a specific th eory. Most cognitive models refer to procedural prototypes, but an alt ernative is to focus on contextual control. A model is proposed which explicitly describes the way in which actions are chosen to meet the r equirements of a situation. Control is described in terms of different control modes, which match different performance characteristics.
