Abstract
Two experiments investigated how people assign an interpretation to question phrases. In order to determine the meaning of the WH-phrase (e.g., who, what), a “gap” must be located and the role associated with the gap assigned to the WH-phrase. Two experiments tested the Lexical Expectation model of Fodor (1978), according to which lexical properties of the verb determine when a gap is posited, and the All Resorts model of Stowe (1984), according to which all possibilities are considered and evaluated on their pragmatic appropriateness. In Experiment 1, subjects judged the meaningfulness of full sentences. The frequency with which verbs are used transitively determined whether there was an effect of the plausibility of the WH-phrase to act as an object of the verb. Effects of plausibility of the WH-phrase as an object showed up in just those cases where the object role should be assigned to the WH-phrase according to the Lexical Expectation model, rather than as predicted by the All Resorts model. In Experiment 2, these results were replicated using the word-by-word self-paced reading paradigm. The plausibility effect showed up at the verb itself when it is normally used transitively. This evidence suggests that a gap is preferred even over a lexically filled object for transitive expectation verbs.
