Abstract

The sequential constraints of pairs of letters were computed for a series of graded readers. Information in single letters is about the same for all texts. Redundancy decreases with increasing grade in a regular way, while mean word length increases. A third reader has about the same redundancy as simple adult text. The constraints in a first reader are considerable, whereas those in a fifth reader approach those in average adult text.
