This study looked at the effects of feedback (explicit correction) on the learning of morphological generalizations in an experimental setting. Subjects were 79 adult native speakers of English with intermediate (39) and advanced (40) levels of proficiency in French. All subjects were individually trained on two rules of French suffixation. Experimental subjects received correction if they gave erroneous responses to stimuli in a "feedback" session. Afterward, all subjects "guessed" responses to novel stimuli and were retested (twice) on the feedback items. Comparison subjects dealt with the same stimuli but were never corrected. Analyses of feedback responses indicated differences in favor of the experimental groups, but comparisons of guessing responses between experimental and comparison groups showed no evidence of learned generalizations. The learning of absolute exceptions was more likely among advanced learners.The subject of feedback and its role in language acquisition has recently undergone a revival in interest. In the heyday of behaviorism, there were numerous studies of correction as a form of behavioral conditioning. With the advent of information-processing theories of mind, correction was discussed in terms of "feedback," and the latter term stuck. The focus of much of this information-processing research covers nonlinguistic learning, however. There is, for example, an extensive literature on feedback and its effects on memory for content (see the reviews in Kulhavy, 1977, andLysakowski &Walberg, 1982). By "content" we mean the information expressed by language or the propositional content of sentences. (Therefore,
