The structural description ansatz often used for representing and recognizing complex objects leads to the consistent labeling problem or to some optimization problems on labeled graphs. Although this problems are NP-complete in general it is well known that they are easy solvable if the underlying graph is a tree or even a partial m-tree (i.e its treewidth is m). On the other hand the underlyi...

The aim of this article is to describe the morpho-syntactic alternations Old English verbs inaction. method includes analysis syntactic constructions in which inaction are found and themselves, described as argumenthood, morphological case, prepositional government structural complexity. Two types alternation identified on basis affected argument. dative reflexive involve both first second argu...

Event-related potentials were recorded from 13 scalp locations while participants read sentences containing a syntactic ambiguity. In Experiment 1, syntactically disambiguating words that were inconsistent with the "favored" syntactic analysis elicited a positive-going brain potential (P600). Experiment 2 examined whether syntactic ambiguities are resolved by application of a phrase-structure-b...

BACKGROUND In addition to declines in auditory acuity, adult aging is often also accompanied by reduced cognitive efficiency, most notably in working memory resources and a general slowing in a number of perceptual and cognitive domains. Effectiveness of speech comprehension by older adults reflects a balance between these declines and the relative preservation in healthy aging of linguistic kn...

PURPOSE The purpose of this study was to compare online effects of syntactic complexity in written and spoken sentence comprehension in people with aphasia (PWA) and adults with no brain damage (NBD). METHOD The participants in Experiment 1 were NBD older and younger adults (n = 20 per group). The participants in Experiment 2 were 10 PWA. In both experiments, the participants read and listene...

Language comprehension recruits an extended set of regions in the human brain. Is syntactic processing localized to a particular region or regions within this system, or is it distributed across the entire ensemble of brain regions that support high-level linguistic processing? Evidence from aphasic patients is more consistent with the latter possibility: damage to many different language regio...
