This paper advocates the view.of readability as an interaction between text structure and the cognitive processes and struCtures possessed by a reader. A simulation mOdel of.prose comprehension that yields predictions of both propositional recall and text readability bastat on the frequencies of different processing events is discussed. The paper noter that the model is.being extended to include the knowledge based aspects of comprehension, including the representation of text-relevant world knowledge ard tcp-down processes that observe the constraints established in ft text as a result of the interaction between a text and a reader's knowledge. Experiments that examine the kinds of expectations which are made during reading and the factors that determine the ccntent and specificity of these expectations are reported. The early stages of a simulation model that intearates'knowledge structures with top-down and bottom-up processes4are also lescribed.
