Comprehension of complement clauses embedded into 4 matrix verbs in Greek, equivalent to English in syntactic and semantic constraints, was studied among 32 mildly retarded and 32 nonretarded Greek elementary-level students. Results indicated equal comprehension, but retarded subjects lacked metalinguistic ability. Digit span and verbal…

Describes the possible improvements in the quality of automatic indexing systems gained by using complex descriptors, and reports on the effectiveness of a simple nonsyntactic phrase indexing procedure. The discussion covers shortcomings of this approach, possible methods for improvement, and areas needing further research. (43 references) (CLB)

Experienced deaf-blind users (N=10) of sign language tested their ability to receive signed messages including isolated signs and sentences. A set of 122 isolated signs was received with an average accuracy of 87%. Signed sentence reception accuracy ranged from 60-85%, with errors accounted for primarily by deletions and phonological or…

Unlike conventional information retrieval systems, natural language processing (NLP) systems translate queries automatically into the language of the system. This paper discusses the potential impact of NLP on both the indexing and retrieval of text and examines some current NLP projects and systems that have established knowledge bases in narrow…

The concept of language learning disability is discussed in terms of such language components as phonology, morphology, syntax, semantics, and pragmatics; input and output dimensions of language performance; information processing; and the social construction of meaning. (DB)

Two experiments were performed on the ability of children and adults to understand and produce locative verbs. Results confirm that children tend to make syntactic errors with sentences containing "fill" and "empty," encoding the content argument as direct object. (33 references) (JL)

Analyzed longitudinal data from 28-year-old Cambodian man who, despite instruction in English-as-Second-Language and residence in English-speaking community, used form "has" for both possessives (PO) and existentials (EX). Shared semantic properties of PO/EX, together with syntactic, pragmatic, perceptual characteristics of native…

Explores the acquisition process of relative clauses in Japanese and Korean. Examines the issue of whether Korean "kes" and Japanese "no" found in Korean and Japanese relative clauses are each a complementizer or a head noun.(Author/VWL)

Explores two Mandarin-speaking children's ability to refer to the past in mother-child conversation. The approach encompasses morphosyntactic, semantic, and discourse-pragmatic perspectives. Results show that the children tend to refer to immediate past spontaneously, but rely heavily on elicitation when referring to earlier past. (Author/VWL)

Language characteristics of 11 children (ages 6-8) with attention-deficit/hyperactivity disorder (ADHD) and 11 typically developing children were compared for semantic, syntactic, and pragmatic language skills. Findings indicated no differences on receptive vocabulary, but children with ADHD performed worse on tests of expressive speech and…

Describes a system called CINDI (Concordia INdexing and DIscovery System) for cataloging and searching documents in a distributed virtual library. The document author registers metadata in the form of a semantic header that contains information on syntactic and semantic content, and an expert system fills the semantic header according to accepted…

The population of children in the United States who require English as a second language (ESL) instruction increases every year. Among this diverse group of learners, which now exceeds four million, are learning disabled students. Their evaluation for special education services presents significant challenges to ESL, general education, and special…

Written language requires prior knowledge of many foundation language skills. Students with language learning disabilities find it difficult to integrate language skills into academic writing assignments. Exceptional educators can teach foundation writing skills through certain underlying components of language, that is, phonology, morphology,…

Forty-four children (mean 3.8 years) were given three false belief, a working memory, and four language tasks (each designed to tap a different aspect of syntax or semantics), and were tested again 6 months later. Once the range of scores in the language and false belief tasks were equated, there was a bidirectional relation between language and…

Lidz, Waxman, and Freedman [Lidz, J., Waxman, S., & Freedman, J. (2003). What infants know about syntax but couldn't have learned: Evidence for syntactic structure at 18-months. "Cognition," 89, B65-B73.] argue that acquisition of the syntactic and semantic properties of anaphoric one in English relies on innate knowledge within the learner.…
