Prader-Willi syndrome (PWS), most recognized for the hallmark hyperphagia and food preoccupations, is caused by the absence of expression of the paternally active genes in the q11-13 region of chromosome 15. Since the recognition of PWS as a genetic disorder, most research has focused primarily on the medical, genetic, and behavioral aspects of…

Purpose: The impact of a newly designed computer-assisted treatment ("C-AT") program, "My Sentence Builder", for the remediation of expressive-grammar deficits in children with specific language impairment (SLI) was explored. This program was specifically designed with features to directly address expressive-grammar difficulties, thought to be…

Gains made by a woman with Broca's aphasia as documented by traditional measures were paralleled by changes in conversation, including increased verbal output and efficiency, and changes in conversation-repair patterns. The progress documented with conversational discourse analysis was not observable from other test measures. (Author/DB)

Spontaneous utterances from 3 conversational contexts were generated by 3 groups of 10 children, including children with specific language impairments (SLI), and analyzed for accuracy of pronoun usage. Results indicated that children with SLI exhibited more total errors than chronological peers but not more than their language level peers. A…

Fifteen children (grades 3-5) with specific language impairment (SLI) were asked to define 10 common nouns. Children with SLI scored significantly lower than children with typically developing language for both content and form. Results suggest that lexical access and/or lack of metalinguistic knowledge were potential causes for the lower scores…

This study compared pragmatic skills of 5 children (ages 4-6) with specific language impairments (SLI) and their younger siblings matched for mean length of utterance. Analysis of communicative acts on three levels (social interchange, speech act, and conversational) indicated comparable performance within sibling pairs, but SLI children…

Thirty-two subjects (5 Broca's, 7 conduction, and 10 anomic aphasics and 10 normal controls) performed story retell and procedural discourse tasks containing familiar and unfamiliar topics, with familiar and unfamiliar listeners. Results indicated that topic familiarity significantly influenced verbal output in both normal and aphasic subjects.…

This study used dependency analysis to document and describe the narrative discourse impairments of 10 children (mean age 12) and 10 adults (mean age 35) with traumatic brain injury (TBI), and matched controls. Individuals with TBI were significantly more disfluent than controls and their narrative performance required a significant listener…

The performance data of individuals with Alzheimer's on language comprehension and expression tests are presented and discussed in the context of possible contributions from impaired working memory functions. It is argued that diminished scores result primarily from attenuated span capacity, difficulty focusing attention, encoding, and activation…

Discusses the use of augmentative and alternative communication (AAC) to enhance comprehension and expression of people with autism. A theoretical model for AAC assessment and intervention is presented and illustrated with a case study of a 6-year-old boy with autism and severe expressive and receptive language impairments. (Author/DB)

A study of 458 6-year olds (204 prenatally exposed to cocaine), found low language children (n=57) were more likely to be cocaine exposed (63.1 percent), with cocaine-exposed children 2.4 times more likely to be in the low language groups compared with control children after adjustment for covariates. (Contains references.) (Author/CR)

Connected speech of 134 healthy, Canadian French-speaking adults, grouped according to age and education level, was analyzed using an aphasia battery. Results demonstrated that older subjects with less education produced fewer content units and were less efficient in transmitting lexico-semantic information. Effects of age and education level on…
