Sentence comprehension and grammaticality judgment were studied in 10 healthy subjects and 10 agrammatic aphasic stroke patients. The latter were able to make grammaticality and comprehension judgments, but less accurately. Results indicated that such judgments are made using different processes and/or operate on different aspects of language…

A study of individual patterns of usual and unusual phonological process occurrence in nine phonologically disordered children revealed that a small, basic subset of phonological processes accounted for the majority of errors made, with frequency the distinguishing characteristic among individuals. Unusual processes were primarily changes in word…

Comprehension and strategy use of 18 autistic children was compared with that of normal 3- and 4-year olds. Subjects were asked to act out certain syntactic and semantic patterns in two experiments. Autistic children performed below the levels of the normal subjects, suggesting that autism is a semantic/cognitive deficit. (PJM)

One of a series of semiannual reports, this paper presents articles exploring the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical research applications. Titles of the papers and their authors are as follows: (1) "Lexical Organization and Welsh Consonant Mutations" (S. Boyce, C. P.…

A study compared learning disabled (LD) adolescents with oral expressive problems to non-learning-disabled (NLD) adolescents on a formal operations task, with emphasis on a comparison between non-verbal performance and verbal explanations of the task. This paper reports part of the study, a comparison of two high school freshman subjects. The task…

Reports on six experiments examining the relationships between language processing in the Roman v the Cyrillic alphabets, both of which are used to read Serbo-Croatian. Notes some of the problems involved in operating with two separately used symbol systems. (Author/RL)

Assesses the relationship between production deficits and speech perception abilities. A categorical perception paradigm was administered to a group of communication disordered children and to a matched control group. Group results are tentatively interpreted as showing a moderate perceptual deficit in the communication disordered children of this…

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)

A study investigating the independence of linguistic abilities from each other, specifically the separability of syntax and semantics and the autonomy of syntactic abilities, is described. In the study, 30 individuals with Alzheimer's disease produced spontaneous conversations, completed sentences eliciting 16 grammatical forms, and when possible,…

Recall performance of 22 first-grade and third-grade children who failed memory portions of a speech-language-memory screen was examined using digit and consonant-vowel (CV) stimulus sets. Data indicate children failing the screening battery differed quantitatively, rather than qualitatively, from children passing the screening batter. (Author)

Children (ages 6-7 and ages 8-9) and adults participated in real-word and nonword lexical decision tasks and an auditory-vocal reaction time task. Response times on all tasks decreased with age. However, age-related differences on the real-word lexical decision task disappeared when differences in auditory-vocal reaction times were taken into…

A significant proportion of the 45 Ss made language age gains of more than six months on subtests of the Illinois Test of Psycholinguistic Abilities (ITPA) and the Detroit Tests of Learning Aptitude (DTLA) and on the Carrow Elicited Language Inventory. (Author/SB)

Proposes a theoretical information-processing-based neuropsychological model of writing and oral spelling which contains linguistic and motor components and which helps explain agraphia independently of other language disorders. Disruption of the phonological system is thought to cause phonological agraphia. Disruption of the lexical system is…

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-two hyperactive children were more spontaneously talkative than controls during transitions and nonverbal tasks (nonelicited conditions), but less talkative when asked to tell stories (elicited conditions). Findings suggest that minimal stimulus input precipitate excessive verbal activity from hyperactive children, while stories requiring…
