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…

The aim of this longitudinal study was to obtain information on the early lexical development and its predictive value to language skills in very-low-birth-weight (VLBW) children. The MacArthur Communicative Development Inventory was used to collect data of the early receptive and expressive lexicon of the 32 VLBW children. This information was…

Partially hearing (N=16), deaf (N=20), and normal hearing (N=10) children's ability to say, write, and comprehend the same sentences were compared. Among results were that the partially hearing made more errors in both the spoken and written conditions than hearing subjects who were two years younger. (Author/DB)

Studies of American Sign language including functional magnetic resonance imaging of deaf signers confirms the importance of left hemisphere structures in signed language, but also the contributions of right hemisphere regions to sign language processing. A case study involving cortical stimulation mapping in a deaf signer provides evidence for…

The receptive and expressive "wh" interrogative performance of 20 language-delayed children (4.3 to 6.4 years old) was compared to available normative data. These findings suggest that the delayed children develop the same order of acquisition and rules for questioning as normal children, but at a slower rate. (Author/SEW)

The communicative abilities of six sets of same-sex, preschool dizygotic twins were examined. In each dyad, one sibling had a strong history of recurrent otitis media (ROM) but the other twin did not. History of ROM was associated with lowered receptive vocabulary, with no consistent effects detected in expressive speech and language tasks.…

Receptive and expressive language skills were assessed in 13 British children (ages 4-14) with cri-du-chat syndrome. Results found a discrepancy between the children's chronological ages and their presumed language ages and a receptive-expressive discrepancy, with reduced expressive skills compared to receptive skills. Remediation that focuses on…

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…

The study compared results of the Preschool Language Scale, administered to 214 rural and 214 suburban children in Nebraska. Both groups scored above age level, but a higher percentage of rural children failed a wide range of verbal ability and auditory comprehension items. The scale did not meet criteria for nonbiased, ecologically valid…

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.

A technique for evaluating children's auditory-language processing abilities was developed. Teachers were trained in inservice workshops to identify auditory-language processing problems, using the Observational Profile of Classroom Communication. They subsequently referred 46 nonhandicapped first-, second-, and third-graders for evaluation, which…
