Investigates and compares the real-time language-processing abilities of language-impaired and normal children using a work recognition reaction time paradigm. Results showed that the language-impaired children used linguistic context to facilitate work recognition but were slower to do so than their normally developing peers. (38 references) (GLR)

Analyzed 104 language samples obtained from 42 different normal language learning children at 15, 19, and 35 months of age for the proportional use of 11 grammatical morphemes. Wide variability was found among the samples in the proportional use of each morpheme. (49 references) (JL)

Twenty children, aged six-eight, with normal nonverbal intelligence but language comprehension deficits, were administered tasks of verbal and perceptual proportional analogical reasoning and a problem-solving task of functional analogical reasoning. Compared to controls, subjects were deficient in analogical reasoning. However, when the…

A study investigated language patterning, as an indication of synthetic mental activity, in comparison groups of normal pre-middle-aged adults (30-42 years), normal elderly adults (75-93), and elderly adults (71-91) with Alzheimer's dementia. Semiotic theory was used as the conceptual context. Linguistic measures included the Token Test, the…

This research is testing the suggestion that acquisition and representation of formal language knowledge of dysphasic children is qualitatively different from the normal language acquisition/representation processes. In a cohort-sequential design, aspects of language and cognitive development of 120 dysphasic children aged 6-14 are being analyzed…

Comparison of language-impaired two- to three-year-olds (N=10) and normal one-year-olds (N=15) matched for expressive language revealed that the language-impaired subjects acquired a greater number of object concepts presented in a no-action condition than the normal children, although language-impaired subjects' extensions of the names to new…

An analysis of the use of attenuation (structural or semantic softening of the speech act) and sentence structure in elicited speech acts by normally developing, learning disabled, and developmentally delayed populations is presented. In the normally developing population (1) the development of attenuation strategies is different from structural…
