A novel analysis of coherence using a combination of three criteria (syntactic connexity, pragmatic complexity, and rhetorical well-roundedness) was applied to short narratives produced by a group of 60 Spanish-speaking children of different ages and grades with reading disabilities and compared to those produced by normal children. We posit a scale of 6 degrees of increasing coherence. This feature of children's writing, together with 2 others (viz. number of propositions, or "story points," recovered and number of words employed), was compared to features of children's reading by means of discriminant analysis in relation to age. We show that the combination of age, words read per minute, and degree of coherence achieved an optimal discrimination of the 2 groups.
