Two assessments of American usage frequencies for ninety-seven sentence complement-taking nouns.

Two studies documented the American English usage frequencies for ninety-seven nouns that occur with sentence complements (e.g., "rumor," "The rumor that the student cheated..."). An established usage preference methodology was used (see Connine, Ferreira, Jones, Clifton, & Frazier, 1984; Kennison, 1999). In Study 1, participants completed short fragments that did not contain the overt complementizer "that," as in "The rumor..." In Study 2, participants completed short sentence fragments that contained the overt complementizer, as in "The rumor that..." The results showed that when the complementizer was absent (Study 1), bare (i.e., unmodified) usages and prepositional phrase usages were frequently observed. In contrast, sentence complement and relative clause usages were rarely observed. When the complementizer was present (Study 2), the frequency of sentence complement and relative clause usages varied. The estimates of usage frequency obtained in these studies are intended to be a resource for language comprehension researchers.
