Modeling human cognitive behavior for system design

The use of models of human cognition to help in system design has been a targeted use case nearly since these models were created. These models can be represented as a combination of fixed mechanisms (the architecture) and task knowledge (the learned subtasks) that uses these mechanisms to generate behavior. I first describe how these models might be used in system design and their useful features. I then describe the types of models and architectures and their uses and then conclude with what appears to be necessary to use these models more routinely.
