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…

It is well established that monolingual preschoolers' oral language development (vocabulary and oral comprehension) contributes to their later reading abilities; however, less is known about this relationship in bilingual populations where children are developing knowledge of two languages. It may be that children's abilities in one language do…

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…

Floating-Harbor syndrome is a rare congenital disorder characterized by specific facial features, short stature associated with significantly delayed bone age and language impairment. Although language delay is a cardinal manifestation of this syndrome, few reports describe the specific language difficulties of these patients, particularly the…

Two studies examined the ability of 22 deaf high school students to instantiate (select appropriate word meaning from context) particular exemplars of general nouns and to use those instantiations as retrieval cues. Among results were that subjects could instantiate when asked to do so but did not do so spontaneously. (Author/DB)

Evaluation of the ability of 12 hearing children (3-year-olds) to use iconic cues to comprehend signs indicated that resemblance of signs to their referents did not enable subjects to decipher the meaning of most signs. Results were applied to use of adapted assessment instruments with young hearing impaired children. (DB)

Aphasic adults (N=16) with severe auditory comprehension impairment were evaluated for comprehension of redundant and nonredundant spoken and/or gestured messages. Results indicated redundancy was not reliably superior to spoken messages alone. (Author/DB)

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)

The effectiveness of verbal, sign, and simultaneous systems for the acquisition of receptive language by an autistic boy was investigated. Results suggest nonsignificant differences among the three methods. (Author/SEW)

Results show that comprehension of word types (nouns, verbs, etc.) and linguistic structure can be orderly, producing a hierarchy of complexity similar to that found in normally hearing children. However, performance was about three years behind that of normally hearing peers. Journal availability: Elsevier North Holland, Inc., 52 Vanderbilt…

Two groups of 10 adult aphasics received auditory-verbal "yes-no" questions, including egocentric, environmental, pictorial, and relationship items, either in a consistent order or random order. Support was found for the existence of a hierarchy of difficulty among the types of questions, but there was no significant difference between…

This study investigated success in responding to naturalistic conversational questions by six young adults with autism, using a quantitative discourse analytic method. Four types of questions were identified: more than seven words in length; multiclausal; requiring inference; and indirect requests for information. The prediction that…

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.…
