During the 1980s an alternative model of reading was proposed that puts together the two views, bottom-up and top-down. The result is called an “interactive” model of the process of reading. It stresses the interplay of all meaning-gathering activities which take place during reading. While the basic theoretical work has centered on native or first language readers, the interactive model has been adopted by many second language reading researchers as well.
Interactive theory acknowledges the role of previous knowledge and prediction, but at the same time, reaffirms the importance of rapid and accurate processing of the actual words of the text. According to the interactive model, the reading process works like this: First, clues to meaning are taken up from the page by the eye and transmitted to the brain. The brain then tries to match existing knowledge to the incoming data in order to facilitate the further processing of new information. On the basis of this previous experience, predictions are made about the content of the text, which, upon further sampling of the data, are either confirmed or revised. Essentially, then, the two processes, bottom-up and top-down, are complementary; one is not able to function properly without the other.
