Our goal in this final chapter is to pull some of the threads together and to summarize some of the things that we know about reading. Thoughout the book, we have concentrated on presenting you with what is really known about reading. In many cases, however, the data were incomplete or equivocal and so we summarized the best available evidence. When it was necessary, we provided some theoretical interpretation, and our interpretations have been guided by an implicit general theory of the reading process. However, in summarizing, we believe that it is useful to make this theory of reading more explicit. In order to place our theory in some context, we will briefly present examples of top-down, bottom-up, and interactive models of reading that have been proposed by others before presenting our model of reading.
