The structural processing of the truncated passive in children and adults.

Three experiments were designed to test the hypothesis that the structural processing of truncated passives is dependent upon the degree to which the past participle syntactically resembles an adjective. Two types of truncated passive were distinguished, one predicted to be processed according to the standard transformational account, and the other analogously to the predicate adjective construction. In sentence-completion tasks, both children and adults showed differential rates of agentive phrase recovery to the two types of truncated passive. A third experiment showed that the linguistic intuitions of adult subjects differed for the two types of truncated passive.
