Three examples from the literature demonstrate the kind of phenomena that need to be covered by cognitive models of error. A novel cognitive architecture for the modelling of human behaviour and error is here outlined. It is based on classes, and instances, of entities and of situations, represented in a contextually modular way as task units. Crucially, there are two kinds of transition between task unit instances. In known situations it is rule-based, whilst in unusual cases it is governed by matching the current state representation against normal state envelopes of usual, expected states.
