Reading time evidence for enriched composition.

Verbs like 'begin' and 'enjoy' appear to semantically select a complement that expresses an activity or an event (Jackendoff, R. (1997). The architecture of the language faculty. Cambridge, MA: MIT Press; Pustejovsky, J. Cognition 41 (1991) 47; Pustejovsky, J. (1995). The generative lexicon. Cambridge, MA: MIT Press). When these verbs occur with a complement that does not directly denote either an activity or an event (e.g. '... began the book' or '... enjoyed the book'), the complement must be type-shifted from an object to an activity to conform to the verb's semantic restrictions. We report an experiment in which self-paced reading times were found to be longer for complements that required type-shifting than for complements that directly matched the semantic restrictions of the matrix verb. This finding is argued to provide on-line evidence for a type of enriched lexical processing posited in recent lexical semantic research.

Processing ambiguous verbs: evidence from eye movements.

In 2 eye-tracking experiments, participants read verbs that had 2 (unrelated) meanings or 2 (related) senses in contexts that disambiguated before or after the verb, to the dominant or subordinate interpretation. A 3rd experiment used unambiguous verbs. The results indicated that the language processor used information about context in the early stages of resolving meaning ambiguities but only during integration for sense ambiguities. Effects of preference were delayed for both types of verbs. The results contrast with findings concerning the processing of nouns (e.g., K. Rayner & S. A. Duffy, 1986). For meaning ambiguities, the authors argue that delays in resolution allow both meanings to reach a high level of activation, thus reducing effects of frequency. For sense ambiguities, the authors argue that the processor does not access multiple senses but activates one underspecified meaning and uses context to home in on the appropriate sense.

Lexical guidance in sentence processing: a note on Adams, Clifton, and Mitchell (1998).

Mitchell (1987) conducted a self-paced reading experiment that showed that people experienced difficulty reading a noun phrase when it immediately followed an intransitive verb. From this, he argued for a two-stage theory of parsing, in which verb subcategorization information is initially ignored. In response, Adams, Clifton, and Mitchell (1998) found no evidence to support this claim in an eye-tracking experiment and argued that Mitchell's segmentation procedure distorted the parsing process. We report an eye-tracking experiment, in which materials similar to those in Adams et al., but with longer noun phrases, were used, that showed a pattern of difficulty similar to Mitchell's findings. Hence, Mitchell's results did not depend on the use of an artificial method of presentation. The results cast further doubt on the adequacy of constraint-based accounts of parsing.

Strategies for processing unbounded dependencies: lexical information and verb-argument assignment.

This article describes 2 experiments about verb-argument relations in sentence processing in which there is no ambiguity involving the subcategorization of the verb but in which the role that the argument serves is initially unclear. Specifically, a self-paced reading experiment and an eye-tracking experiment investigated the way in which readers form unbounded dependencies when the verb is looking for both a direct object and a clause and when the filler either could be the direct object or could form part of the clause. The results suggested that readers treated the filler as the verb's direct object and probably also considered the clausal analysis at the same time. The results are interpreted with respect to current accounts of parsing.

Syntactic co-ordination in dialogue.

There is substantial evidence that speakers co-ordinate their contributions in dialogue. Until now, experimental studies of co-ordination have concentrated on the development of shared strategies for reference. We present an experiment that employed a novel confederate-scripting technique to investigate whether speakers also co-ordinate syntactic structure in dialogue. Pairs of speakers took it in turns to describe pictures to each other. One speaker was a confederate of the experimenter and produced scripted descriptions that systematically varied in syntactic structure. The syntactic structure of the confederate's description affected the syntactic structure of the other speaker's subsequent description. We suggest that these effects are instances of syntactic priming (Bock, 1986), and provide evidence for a shared level of representation in comprehension and production. We describe how these effects might be realized in a processing model of language production, and relate them to previous findings of linguistic co-ordination in dialogue.

Search strategies in syntactic reanalysis.

We first consider the nature of syntactic reanalysis, paying particular attention to questions about whether and how it differs from the construction of an initial analysis, such as whether it is encapsulated or whether alternatives are considered in parallel or not. We then outline different strategies that the processor may use in reanalysis, and review the relevant evidence. We show that our experimental evidence is compatible with an encapsulated serial search strategy.

Activation of syntactic information during language production.

In order to produce utterances, people must draw upon syntactic information. This paper considers how evidence from syntactic priming experiments casts light upon the nature of syntactic information activation during language production. We examine three issues: the way in which syntactic information is initially activated, the circumstances under which activation may persist or dissipate, and the effects of residual activation of syntactic information on subsequent language production. Evidence from dialog experiments suggests that the information that is initially activated is the same in both production and comprehension. Evidence about the persistence of activation following initial activation is more complex. We suggest that persistence may be related to the potential relevance of the information for subsequent syntactic processing. We show that current evidence is inconclusive about how long syntactic information remains activated.

Syntactic priming in spoken production: linguistic and temporal interference.

Current evidence about the persistence of syntactic priming effects (Bock, 1986) is equivocal: Using spoken picture description, Bock and Griffin (2000) found that it persisted over as many as 10 trials; using written sentence completion, Branigan, Pickering, and Cleland (1999) found that it dissipated if even a single sentence intervened between prime and target. This paper asks what causes it to be long lasting. On one account, the rapid decay evidenced by Branigan et al. occurs because the task emphasizes conceptual planning; on another account, it is due to the written nature of their task. If conceptual planning is the cause, this might relate to planning the prime sentence or planning an intervening sentence. Hence we conducted an experiment with spoken sentence completion, contrasting no delay, an intervening sentence, and a pure temporal delay. The results indicated that strong and similar priming occurred in all three cases, therefore lending support to the claim that spoken priming is long lasting.

The processing of metonymy: evidence from eye movements.

The authors investigated the time course of the processing of metonymic expressions in comparison with literal ones in 2 eye-tracking experiments. Experiment 1 considered the processing of sentences containing place-for-institution metonymies such as the convent in That blasphemous woman had to answer to the convent; it was found that such expressions were of similar difficulty to sentences containing literal interpretations of the same expressions. In contrast, expressions without a relevant metonymic interpretation caused immediate difficulty. Experiment 2 found similar results for place-for-event metonymies such as A lot of Americans protested during Vietnam, except that the difficulty with expressions without a relevant metonymic interpretation was somewhat delayed. The authors argue that these findings are incompatible with models of figurative language processing in which either the literal sense is accessed first or the figurative sense is accessed first. Instead, they support an account in which both senses can be accessed immediately, perhaps through a single under-specified representation.

Syntactic priming in written production: evidence for rapid decay.

There is strong evidence for syntactic priming in language production (Bock, 1986), but little evidence about the time course of such effects. We report an experiment that examined the circumstances under which syntactic priming decays in written language production. Participants completed sentence fragments that allowed completions with one of two syntactic forms (Pickering & Branigan, 1998). They tended to produce the same syntactic form for immediately consecutive fragments, even though the two fragments described different events. However, when the experimental fragments were separated by other fragments with unrelated syntactic forms, this tendency rapidly diminished. The results suggest that priming effects in written production decay rapidly when other structures are subsequently produced. We discuss the implications for the application of syntactic information during production.

Case-marking in the parsing of complement sentences: evidence from eye movements.

An eye-tracking experiment investigated the role of case-marking in parsing. We manipulated the case of pronouns in reduced complement sentences like I recognized you and your family would be unhappy here and I recognized she and her family would be unhappy here, in which the nominative pronoun she immediately disambiguates the sentences, in contrast to the ambiguous you. The nominative pronoun she disambiguates the sentence because I recognised she is ungrammatical, and thus she and her family must be the subject of an embedded sentence and not the NP-object of the preceding verb. Subjects took longer to read she and her family than you and your family during initial processing. The pattern reversed at the disambiguating phrase would be. Unambiguous control sentences containing the complementizer that did not produce case-marking effects. These results demonstrate very rapid effects of case-marking on parsing. Either case information is used immediately, or it is employed after an extremely short delay. We discuss implications for current theories of parsing.

Processing syntactically ambiguous sentences: evidence from semantic priming.

In this paper, we report the results of a study which investigates the processing of syntactically ambiguous sentences. We examined the processing of sentences in which an embedded clause is interpretable as either a complement clause or as a relative clause, as in, for example, "The receptionist informed the doctor that the journalist had phoned about the events." The embedded clause in such sentences is typically analyzed as a complement to the verb informed, rather than as a relative clause modifying the doctor. A number of models parsing predict this is the only analysis ever considered, while others predict that both interpretations are computed in parallel. Using a cross-model semantic priming technique, we probed for activation of doctor just after the embedded verb. Since only the relative clause analysis contains a connection between the doctor and the embedded verb, we expected reactivation of doctor at that point only if the relative clause analysis were a viable option. Our results suggest that this is the case: Compared to priming in an ambiguous control sentence, a significant reactivation effect was obtained. These results are argued to support a model of parsing in which attachment of a clause may be delayed.

Deafness associated with oral furosemide.

A patient with Hodgkin's disease and renal insufficiency became deaf while being treated with high dose oral furosemide. Cessation of furosemide was associated with improvement in his hearing. However, at the time of his death, 11 days after stopping the furosemide, significant hearing impairment was still present. It is suggested that oral furosemide be considered potentially ototoxic, particularly in patients with compromised renal function.
