Reading has been studied for decades by researchers from a wide variety of fields. Education researchers studied the process from a pragmatic perspective; they were interested in understanding it so that it might be taught more effectively. Cognitive psychologists studied reading, believing that it represented a ``high'' cognitive function; by understanding reading, general cognition could begin to be understood. Finally, artificial intelligence researchers examined reading as a way to demonstrate intelligent performance from theories and models of cognition. With all this effort, literally dozens of theories, models, and frameworks have been proposed and tested. Why do we need another theory? The framing for the answer can be found by examining some of these past attempts.
