PURPOSE This article addresses complexity in the context of treatment for sentence structural impairments in agrammatic aphasia, with emphasis on noncanonical sentences involving linguistic movement and their related counterparts. Extensions of the complexity effect to recovery of canonical sentences also are discussed, stressing the linguistic properties of verbs as well as grammatical morphol...

A formal treatment of typed feature structures (TFSs) is developed to augment TFSs, so that negative descriptions of them can be treated. Negative descriptions of TFSs can make linguistic descriptions compact and thus easy to understand. Negative descriptions can be classified into three primitive negative descriptions: (1) negations of type symbols, (2) negations of feature existences, and (3)...

Objectives: Stuttering is one of the most prevalent speech and language disorders. Symptomology of stuttering has been surveyed from different aspects such as biological, developmental, environmental, emotional, learning and linguistic. Previous researches in English-speaking people have suggested that some linguistic features such as word meanings may play a role in the frequency of speech non...

In order to resolve metonymy and other violations of selectional restrictions between lexical items, a language understander must be able to infer relationships that do not have explicit lexical analogs in tile sentence. Although such inferencing has typically been relegated to the world knowledge portion of a natural language processing system, there is also evidence, from both theoretical ana...

Though most documented sign languages make use of space to denote relationships between predicate arguments, studies of emerging sign languages suggest that spatial reference does not emerge fully-formed but takes time to develop. We present an artificial sign language learning experiment that expands the cultural evolutionary framework to investigate complex linguistic constructions. Our resul...

Over their evolutionary history, languages most likely increased in complexity from simple signals to protolanguages to complex syntactic structures. This paper investigates processes for increasing linguistic complexity while maintaining communicability across a population. We assume that higher linguistic communicability (more accurate information exchange) increases participants’ effectivene...

The present work offers a corpus-based approach to the processing of complex constructions, specifically bi-clausal English relative clause constructions (RCC). At the most general level, the goal of the investigation is to help bridge the gap between linguistic and psycholinguistic research. Following a usage-based view on grammar (Langacker 2008), it is presumed that the processing demand of ...

In this paper, we explore different linguistic structures encoded as convolution kernels for the detection of subjective expressions. The advantage of convolution kernels is that complex structures can be directly provided to a classifier without deriving explicit features. The feature design for the detection of subjective expressions is fairly difficult and there currently exists no commonly ...
