Two experiments measured the frequency of perceptual errors as a function of differential presupposition in descriptive sentences. More errors occurred when misrepresentation involved presupposition than when it involved the focused proposition. Several surface structures of English, in combination, increased the presuppositional strength of the…

An experiment is reported which permitted the separate examination of sentence comprehension processes and subsequent sentence memory processes. The similarity between the results of comprehension and recall was discussed in terms of a retrieval process that may be similar in both tasks. (Author/RM)
