A major open question in natural language research is the role of communicative efficiency in the origin and on-line processing of language structures. Here, we use word pairs like "chimp/chimpanzee", which differ in length but have nearly identical meanings, to investigate the communicative properties of lexical systems and the communicative…

Although sentences are thought to be generally easier to process when given information precedes new information, closer examination reveals that these preferences only manifest within some syntactic structures. Here, we examine the consequences of the relative ordering of given and new information ("information structure") for the on-line…

Linguistic dependencies between non-adjacent words have been shown to cause comprehension difficulty, compared with local dependencies. According to one class of sentence comprehension accounts, non-local dependencies are difficult because they require the retrieval of the first dependent from memory when the second dependent is encountered.…

Results from two self-paced reading experiments in English are reported in which subject- and object-extracted relative clauses (SRCs and ORCs, respectively) were presented in contexts that support both types of relative clauses (RCs). Object-extracted versions were read more slowly than subject-extracted versions across both experiments. These…

In most languages, most of the syntactic dependency relations found in any given sentence are projective: the word-word dependencies in the sentence do not cross each other. Some syntactic dependency relations, however, are non-projective: some of their word-word dependencies cross each other. Non-projective dependencies are both rarer and more…

This paper evaluates two classes of hypotheses about how people prosodically segment utterances: (1) meaning-based proposals, with a focus on Watson and Gibson's (2004) proposal, according to which speakers tend to produce boundaries before and after long constituents; and (2) balancing proposals, according to which speakers tend to produce…

This paper reports the results of four dual-task experiments that were designed to determine the extent of domain-specificity of the verbal working memory resources used in linguistic integrations. To address this question, syntactic complexity was crossed in a 2x2 design with the complexity of a secondary task, which involved either (1)…

Proposes that the P600 component in event related potential research is not restricted to reanalysis processes, but reflects difficulty with syntactic integration processes in general. (Author/VWL)

This paper investigates how people resolve syntactic category ambiguities when comprehending sentences. It is proposed that people combine: (a) context-dependent syntactic expectations (top-down statistical information) and (b) context-independent lexical-category frequencies of words (bottom-up statistical information) in order to resolve…

Presents results from a self-paced reading experiment in Japanese investigating attachment preferences for relative clauses to three ensuing potential nominal heads. Results are discussed in light of two types of parsing models. (Author/VWL)

All other things being equal the parser favors attaching an ambiguous modifier to the most recent possible site. A plausible explanation is that locality preferences such as this arise in the service of minimizing memory costs--more distant sentential material is more difficult to reactivate than more recent material. Note that processing any…

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.

Results from an English acceptability-rating experiment are presented that demonstrate that people find doubly nested relative-clause structures just as acceptable when only two verb phrases are included instead of the grammatically required three. Three possible accounts of the results are considered. (Author/VWL)

Presents two questionnaire experiments that investigated the processing complexity of a variety of nested constructions in Japanese. The results are discussed in terms of the syntactic-prediction locality theory. (Author/VWL)

This paper reports the results of a dual-task experiment which investigates the nature of working memory resources used in sentence comprehension. Participants read sentences of varying syntactic complexity (containing subject-and object-extracted relative clauses) while remembering one or three nouns (similar to or dissimilar from the…
