This study examined discourse cohesion in young normal (n=8), specifically language-impaired (n=8), or autistic (n=10) children (ages 3-7). Results showed all three groups used the same cohesion strategies with similar patterning. Significant group differences were found in the overall rate of correct use and in the use of individual cohesive…

Sign language production of 14 low-functioning students (ages 9 to 20) with autistic disorder were examined. The location aspect of signs was produced more accurately by subjects than either the handshape or movement aspects. Wide individual differences were observed. Sign vocabulary size and accuracy was correlated with performance on two…

The study with 10 autistic children (ages 4-17) found that those children with poor receptive language skills produced significantly more echolalic utterances than those children whose receptive skills were more age-appropriate. (Author/DB)

This study found that a group of 20 children (ages 6-12) with autism and a group of 20 children with developmental receptive language disorder both manifested a relative sequential processing deficit. The groups did not differ significantly on overall sequential and simultaneous processing capabilities relative to their degree of language…

Comparison of the performance of 25 subjects with autism and 25 nonautistic subjects with mental retardation found all subjects able to comprehend the personal pronouns "I,""you," and "me." However, autistic subjects were less likely to employ the pronoun "me" in a visual perspective-taking task and to say "you" to refer to the experimenter.…

A study of five adult males with autism investigated which combination of input/output modalities (typed or spoken) enhanced the syntactic, semantic, and/or pragmatic performance of individuals with autism when engaging in conversations with a normal language adult. Results found that typed communications facilitated the use of longer utterances.…

This paper discusses language and communication deficits observed in autism within the framework of the "theory of mind" hypothesis, which posits that autistic individuals have profound difficulty interpreting a person's actions within a mentalistic framework. Placing language and communicative deficits within a theory of mind framework…

Preschool children with autism (n=9) and their normally developing peers (n=9) were compared before and after one school year. The autistic children had narrowed the gap after treatment--making a nearly 19-point increase in intelligence quotient and an 8-point gain in language quotient. Results support the value of a language enriched early…

The maladaptive behaviors, personality, and language skills of a male whose chromosome analysis showed evidence of mosaicism with karyotype 49,XXXXY and 48,XXXY are described. Research on severity of mental handicap with extra chromosomes, delayed speech development, and discrepancy between verbal and performance intelligence is examined. (JDD)

Research on the communication, language, social, and emotional development of people with autism is reviewed, concerning individuals who either are nonspeaking/limited speaking or use speech as their primary mode of linguistic communication. Research needs for longitudinal studies, investigation of early developmental patterns, and subgroup…

Twenty-four relatively high-functioning children and adolescents with autism were compared to typically developing children (matched for nonverbal mental age and language level) on three tasks designed to assess the presence of cognitive social scripts. Results indicated that basic scriptal knowledge was intact, but that reliable differences in…

The study examined the use of primary sentence stress by seven preschool autistic children with mean length of utterance (MLU) scores between 1.9 and 4.1 morphemes with normal and aphasic subjects serving as controls. Differences were seen in the number of correct responses and in the pattern of stress misassignment. (Author/DB)

The study compared the attention-directing behaviors of 15 autistic children, 14 children with developmental language delay, and 13 young normal children. Although the autistic children's behavior was most unlike that of the other groups, autistic children did not produce more attention-directing behavior when a high degree of adult direction was…

The follow-up study reports data from a population-based series of 23 Swedish children diagnosed in childhood as suffering from infantile autism and other childhood psychoses and followed through to the ages of 16-23 years. Intelligence quotient at diagnosis and communicative speech development before six years were the most important prognostic…

Analysis of conversations of 15 adults with autism and 17 with developmental receptive language disorders in childhood indicated that the autistic adults showed greater pragmatic impairment because of their greater difficulty in forming context-relevant communicative intentions. Pragmatic impairments arising from failures in translating intentions…
