A theory of comprehension in verification tasks is developed from a general conception of language comprehension. Models are developed for a task involving transfer verbs "borrow" and "loan" and the possession verb "have." Models and theoretical framework are superior in some respects to constituent comparison and conversion models. (CHK)

Three experiments investigated a characteristic of the propositions that underlie sentences. For some of the sentences tested, the same concepts occurred repeatedly across the underlying propositions; for others, concepts were seldom repeated. Repetitions were shown to facilitate sentence processing. (Author/RM)

Two experiments examined the comprehension of singly and multiply negated sentences. Difficulty of comprehension was measured by the speed and accuracy with which subjects judged the semantic reasonableness of sentences. Marked and negatively prefixed adjectives were a particular focus of the study. (Author/RM)

An experiment is described that involved presenting sentences to the subject for study and then testing single words for recognition (the subject had to decide whether the test word was in one of the study sentences). A large priming effect was obtained. (Author/RM)
