Designed to divide recall protocols for subsequent category analysis, this instrument equates surface syntactic forms with semantic ideas. The instrument defines two types of syntactic proposition--a base syntactic proposition, the simplest independent prediction (structurally) that may be used to convey information, and an alternate syntactic proposition, which can become a base syntactic proposition with the substitution or addition of words. Twenty-three alternative syntactic propositions are listed, subdivided into three groups (1) relativization (intact), (2) relativization (elipsis), and (3) complementation. Validity, reliability, and normative data are included. (This document is one of those reviewed in The Research Instruments Project (TRIP) monograph "Measures for Research and Evaluation in the English Language Arts, Volume 2," published by the Committee on Research of the National Council of Teachers of English in cooperation with the ERIC Clearinghouse on Reading and Communication Skills. The TRIP review, included here as an introduction to the instrument, describes the instrument's category (reading), title, author, date, age range (primary to postsecondary), purpose, and physical characteristics.)
