The question of how people learn and remember information from complex written materials is explored by means of Grime's semantic grammar of propositions and the author's analysis of the content structure of prose. This paper, presented at the 1973 Interdisciplinary Meeting on Structural Learning, first discusses such elements of the semantic grammar of propositions as rules of the grammar, lexical predicates, and rhetorical predicates; it then provides a procedure for the analysis of prose and demonstrates the procedure in an analysis of an exemplary paragraph. Charts, diagrams, and a list of sixteen references are included. (SRW)
