Theories of natural language syntax often characterize grammatical knowledge as a form of abstract computation. This paper argues that such a characterization is correct, and that fundamental properties of grammar can and should be understood in terms of restrictions on the complexity of possible grammatical computation, when defined in terms of…

In setting up a formal system to specify a grammar formalism, the conventional (mathematical) wisdom is to start with primitives (basic primitive structures) as simple as possible, and then introduce various operations for constructing more complex structures. An alternate approach is to start with complex (more complicated) primitives, which…

As an occasional visitor to the land of SLA, I found myself somewhat mystified by the approach of Truscott and Sharwood Smith (henceforth TSS). Unless I have totally misunderstood them, they are arguing against the separate existence of both a Language Acquisition Device (LAD) and a Universal Grammar (UG). But who ever thought they were two?…

Hierarchical models of agrammatism propose that sentence production deficits can be accounted for in terms of clausal syntactic structure [Friedmann, N., & Grodzinsky, Y. (1997). "Tense and agreement in agrammatic production: Pruning the syntactic tree." "Brain and Language, 56", 397-425; Hagiwara, H. (1995). "The breakdown of functional…

Individuals with agrammatic aphasia may have difficulty with verb production in comparison to nouns. Additionally, they may have greater difficulty producing verbs that have fewer semantic components (i.e., are semantically "light") compared to verbs that have greater semantic weight. A connectionist verb-production model proposed by Gordon and…

A number of recent electrophysiological studies of sentence processing have shown that a subclass of syntactic violations elicits very rapid ERP responses, occurring within around 200 ms of the onset of the violation. Such findings raise the question of how it is possible to diagnose violations so quickly. This paper suggests that very rapid…

An investigation looks at complex English sentences that are used to represent two ordered events and containing "before" or "after" subordinate clauses. It is concluded that text evidence is directly relevant to an understanding of language processing. (25 references) (Author/VWL)

Three experiments investigating the use of temporal information in a reduced relative clause to interpret verb tense of the main clause found that subjects rapidly assessed temporal information to resolve tense ambiguity, demonstrating an incremental approach to comprehension that uses previous discourse to continuously update comprehension and…

Proposes a model to account for the uses to which the individual puts formulaic language, and specifically, what determines the choice for that person of a holistic or analytic processing strategy at any given moment. Formulaic language is used to describe a phenomenon that encompasses various types of wordstrings that appear to be stored and…

Background: Previous studies of outcome for children with early language delay have focused on measures of early language as predictors of language outcome. This study investigates whether very early processing skills (VEPS) known to underpin language development will be better predictors of specific language and social communication outcomes than…

Background: Figurative language, such as metaphor and metonymy, is very common in daily language use. Its underlying cognitive processes are sometimes viewed as lying at the interface of language and thought. Williams syndrome, which is a rare genetic developmental disorder, provides an opportunity to study this interface because individuals with…

We report four act-out experiments testing the sensitivity of adults and three- to five-year-old children to the distinction between restrictive and non-restrictive relative clauses in English. Specifically, we test knowledge of the fact that restrictive relative clauses cannot modify a proper name head, and of the fact that relatives introduced…

The acquisition of new skills over a life span is a remarkable human ability. This ability, however, is constrained by age of acquisition (AoA); that is, the age at which learning occurs significantly affects the outcome. This is most clearly reflected in domains such as language, music, and athletics. This article provides a perspective on the…

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)…

Two groups of children were tested at ages five, six, and seven to determine metalinguistic knowledge of the syntactic subject of a sentence. Found that five-year olds had difficulty repeating the pronomial and longest subjects; ability to isolate pronouns improved with age; and ability to identify longest subjects improved with increased…
