Abstract Effective design of interfaces for, e.g., operators engaged in process control tasks, or other complex tasks, requires some kind of model of their cognition.
Models of cognition require some kind of modularity in order to be psychologically plausible.
A few examples of cognitive theories are assessed in these terms. The main thesis proposed here is that for a model to be effective at predicting human behaviour in complex tasks, it must combine clearly defined modules and the mechanisms necessary for switching between them. Some kind of integrated theory of this kind is vital, on grounds of cognitive plausibility, for major progress in the modeling of complex cognition, and could also give a computational model that was able to scale up to realistic size. Practical implications for user modeling and interface design are discussed. An associative mechanism for change of context Discussion References Anderson, J. R. 1983.
