The objectives of the study presented here are to increase the discipline's knowledge about reader performance with technical documents, help writers and editors better allocate their efforts, and explore the effect of semantic and syntactic variables on recall in a single study. For this study, subjects read and recalled one of two technical texts. Their recall protocols were analyzed for numerous syntactic and semantic characteristics. Results suggest that information has a greater chance of being recalled if it is more important, or if it is placed in independent clauses or in the first paragraph of a document.
