This study reexamined previous research and presented new data testing two predictions of the Implicational Generalization Hypothesis, a strong form of Gass's (1981,1982) proposal that instruction focused on one level of an implicational (i.e., markedness) hierarchy such as Keenan and Comrie's (1977) Noun Phrase Accessibility Hierarchy may generalize to uninstructed hierarchy levels. Analyses of sentence combination data from 33 adult ESL learners instructed in sentence combination tasks (a) yielded inconclusive results as to whether implicational generalization (IG) is unidirectional to hierarchy levels implicated by the instructed level, and (b) suggest that IG is clearly not uniformly maximal to all such implicated levels. Moreover, these data suggest that IG is cumulatively constrained; that is, development via IG always involves consecutive levels of the hierarchy (no levels may be skipped). The ramifications of these findings on a theory of IG are discussed, including modifications to Eckman's (1992) explanation of Gin terms of inclusion relations. Addition- ally, the consequences for I earn ability theory in SLA are explored, the data suggesting that learners may not be setting parameters according to the Subset Principle, though they are observing the Cumulative Development Principle and the Continuity Principle.
