This document presents a study of natural language understanding of computer programs. In the study, the performance of IRUS, a natural language query system designed to interface with a database, was compared with the performance of preschool and early elementary school children in answering questions about a specific database. Questions used in…

Although research in episodic recall memory, comparing younger and older adults, favors the younger adults, findings in semantic memory research are less consistent. To examine age differences in semantic and episodic memory recall, 72 young adults (mean age, 20.8) and 72 older adults (mean age 71) completed three memory tests under varied…

The study identified communicative patterns of preschool children (N=11) with handicaps (Down's Syndrome, specific language impairments, and autism). Down's Syndrome children were like normal children of the same language stage on all parameters whereas autistic children scored outside the normal range on all but one parameter. (Author/DB)

This article presents initial guidelines for combining current conventions for analyzing sign language and spoken language, to represent signs accompanied by speech. Rules are outlined for transcribing utterance groupings in terms of their context, inflection, sign gloss, spoken component, and phonetic transcription. (JDD)

Although role or perspective taking has been considered important for the development of mature social thought and behavior, and training for perspective taking has been used to remediate deficient behavior, few studies with either normal or disturbed populations have examined naturally occurring behaviors expected to correlate with…

A lexical representational analysis of Classical Arabic is proposed that captures a generalization that McCarthy's (1979, 1981) autosegmental analysis misses, namely that idiosyncratic characteristics of the derivational binyanim in Arabic are lexical, not morphological. This analysis captures that generalization by treating all the idiosyncracies…

Combinatorial abilities in language and elicited symbolic play were compared in a longitudinal study of 30 children at 20 and 28 months. In addition, multivariate analyses were used to assess the stability of individual differences. Generally, different symbolic play variables contributed unique explained variance to different language variables.…

The continuity in development of syllable duration patterns was examined in seven young children as they progressed from preword to multiword periods of vocalization development. Results revealed no systematic increase or decrease in the duration of bisyllables produced by the children as a group, whereas lengthening of final syllables was…

This study examined the influence of metrical patterns (syllable stress and serial position) of words on the production accuracy of 20 children (ages 22 months to 28 months). Among results were that one-fourth of the initial unstressed syllables were omitted and that consonant omissions, though few, tended to occur in the initial position.…

Research on the cognitive processes used in semantic priming has shown that the processing of a given stimulus is speeded by prior processing of a related stimulus as the result of automatic and/or effortful priming. To investigate the effect of age on semantic priming, two independent studies were conducted at Pomona College in California and at…

Reveals that young children acquiring Mandarin Chinese differentiate subject from topic, even though Chinese is a "topic-prominent" language. Data are based on results of a standardized, elicited imitation test of 95 Chinese children in Taiwan. Subjects between 2 years, 6 months and 5 years of age responded to coordinate as well as…

Examines whether vocal exchanges between preverbal infants and their mothers show characteristics similar to those found to be typical of conversational exchanges between competent adult speakers. (HOD)

Spontaneous speech samples from 10 Swedish children were analyzed grammatically. The five subjects (age five) with specific language impairment (SLI) differed from controls in their more restricted usage of word order patterns and number of grammatical errors. Their speech also showed frequent omissions of grammatical morphemes. Results suggest…

This study evaluated regular and irregular verb class distinctions in the language of two adults with severe congenital physical impairments who relied on augmentative and alternative communication (AAC) systems. Limited evidence for distinction between the two verb classes was found. Theoretical and clinical implications are discussed. (DB)

An investigation, analyzing the linking of skeleton and syntactical rules of Madurese, presents counterevidence to Marantz's claims about the nature of reduplication, and to Carrier-Duncan's claim that reduplication must precede all phonological rules. It is proposed that reduplication in Madurese is not affixation, as Marantz claims, and can be…
