We explore the consequences of letting the incremental and integrative nature of language processing inform the design of competence grammar. What emerges is a view of grammar as a system of local monotonic constraints that provide a direct characterization of the signs (the form-meaning correspondences) of a given language. This "sign-based" conception of grammar has provided precise solutions to the key problems long thought to motivate movement-based analyses, has supported three decades of computational research developing large-scale grammar implementations, and is now beginning to play a role in computational psycholinguistics research that explores the use of underspecification in the incremental computation of partial meanings.

Three experiments investigated whether speakers use constituent ordering as a mechanism for avoiding ambiguities. In utterances like ''Jane showed the letter to Mary to her mother,'' alternate orders would avoid the temporary PP-attachment ambiguity (''Jane showed her mother the letter to Mary,'' or ''Jane showed to her mother the letter to Mary''). A preference judgment experiment confirmed that comprehenders prefer the latter orders for dative utterances when the former order would have contained an ambiguity. Nevertheless, speakers in two on-line production experiments showed no evidence of an ambiguity avoidance strategy. In fact, they were slightly more likely to use the former order when it was ambiguous than when it was not. Speakers' failure to disambiguate with ordering cannot be explained by the use of other ambiguity mechanisms, like prosody. A prosodic analysis of the responses in Experiment 3 showed that while speakers generally produced prosodic patterns that were consistent with the syntactic structure, these patterns would not strongly disambiguate the PP-attachment ambiguity. We suggest that speakers do not consistently disambiguate local PP-attachment ambiguities of this type, and in particular do not use constituent ordering for this purpose. Instead, constituent ordering is driven by factors like syntactic weight and lexical bias, which may be internal to the production system.

Through corpus analysis and experimentation, this article demonstrates that both grammatical complexity (heaviness) and discourse status (newness) simultaneously and independently influence word order in two English constructions. Argues that heavy and new constituents facilitate the processes of planning and production. (Author/VWL)

Two large collections of spontaneous transcribed speech (over 2000 conversations), one U.S. and one British, were analyzed for word repetitions. Four stages of repeated words reflect different principles, and the principles appear to be general and not specific to repeats. (SLD)

The repetition of words in spontaneous speech, often viewed as an error in communication, is a problem-solving strategy that involves complex cognitive processes. A study on the origin of repetitive words was conducted. The four stages of mental processes which include initial commitment to a noun phrase, suspension of speech, hiatus and the restart of a constituent were described. The commit-and-restore model was identified as the framework that explains these cognitive processes. Moreover, the findings confirm that repeated words serve important functions in effective communication.

The verbal coda ('goes' or 'is concerned') is often left off of the construction 'as far as' NP, frequently used as a topic restrictor in modern English. The omission of the verb, which rarely occurred before the 1960s, is becoming more common. The verbless variant is associated with a number of factors, including syntactic complexity of the noun phrase, spoken usage, younger speakers, women, position at the beginning of a sentence, and prosodically branching NP structures. The research has broader implications for syntax, sociolinguistics and the relation between subfields of linguistics.

The English auxiliary system exhibits many lexical exceptions and subregularities, and considerable dialectal variation, all of which are frequently omitted from generative analyses and discussions. This paper presents a detailed, movement-free account of the English Auxiliary System within Sign-Based Construction Grammar (Sag 2010, Michaelis 2011, Boas & Sag 2012) that utilizes techniques of lexicalist and construction-based analysis. The resulting conception of linguistic knowledge involves constraints that license hierarchical structures directly (as in context-free grammar), rather than by appeal to mappings over such structures. This allows English auxiliaries to be modeled as a class of verbs whose behavior is governed by general and class-specific constraints. Central to this account is a novel use of the feature aux , which is set both constructionally and lexically, allowing for a complex interplay between various grammatical constraints that captures a wide range of exceptional patterns, most notably the vexing distribution of unstressed do , and the fact that Ellipsis can interact with other aspects of the analysis to produce the feeding and blocking relations that are needed to generate the complex facts of EAS. The present approach, superior both descriptively and theoretically to existing transformational approaches, also serves to undermine views of the biology of language and acquisition such as Berwick et al. (2011), which are centered on mappings that manipulate hierarchical phrase structures in a structure-dependent fashion. [ABSTRACT FROM AUTHOR]
