Provides evidence that sentence processing does not make use of grammatical theories with empty categories. A linguistic account is provided of unbounded dependencies that do not use empty categories and can serve as the basis of a processing model. It is concluded that empty categories are not psychologically real. (28 references) (JL)

Using the speeded-grammaticality judgment task, shows that factors that regulate garden path strength in ambiguous sentences also have an influence on processing of corresponding ungrammatical sentences in that they determine how reliably the ungrammaticality is detected. Argues that this processing correlation provides evidence for serial parsing…

Recent investigations of filler-gap dependencies in sentence processing have assumed that the parser must compute an antecedent-trace relationship in which the trace site is identical to the canonical position of the moved phrase. Pickering and Barry's challenge to this view is refuted and a "direct association hypothesis" is suggested.…

Pickering and Barry's recent argument against the existence of empty categories (ECs) in human sentence processing is disputed. It is argued here that ECs may still play a linking role between thematic role assigners and wh-phrases. One possible parsing algorithm is given that accounts for Pickering and Barry's data.

Papers by Gorrell and by Gibson and Hickok question Pickering and Barry's (PB) arguments against empty categories in sentence processing. This reply disputes Gorrell's claims that PB's interpretation of the data is inadequate and, in agreement with Gibson and Hickok, reinforces the arguments that the gap location is irrelevant to the formation of…

Presents the case for a mapping theory of developmental language impairment, which branches into a theory that specific language impairment arises from impaired phonological processing and the consequent disruption of the mapping process through which the words and sentence structure of language are established. (Author/VWL)

Studied "pre-ambiguity" plausibility information, information about verb argument structure frequencies, and "post-ambiguity" constraints in undergraduates. All three types of constraints were helpful in the resolution of ambiguities. Ambiguity resolution becomes more difficult as the competitor interpretations becomes stronger. Study items are…

Investigates the relationship between focusing and coherence relations in pronoun comprehension. Examines a function of connectives: that of signaling coherence relations between two clauses. In three studies, coherence relations between sentence fragments ending in pronouns and participants' continuations to the fragments were identified.…

Reviews some history of how lexical representations have acquired an important role in sentence processing research. Discusses relevant issues, including the importance of timecourse information in theorizing; the importance of frequency information in theories of sentence processing; and the question of the grain of frequency information.

Two studies are reported in which the following theory is tested: the agrammatic sentence form that is observed in the spontaneous speech of Broca's aphasics is attributable to the selection of elliptical syntactic structures in which the slots for many of the closed-class words that appear in complete sentences are lacking.
