Investigates construct, predictive, and differential validity for the Comprehensive Receptive and Expressive Vocabulary Test (CREVT). Adequate construct validity for the CREVT was documented, using the Wechsler Intelligence Test for Children-III as a criterion. Also, the CREVT effectively differentiated between students with disabilities. These…

The study demonstrated that 36 male children (ages 7-10) with learning problems were characterized not by a restricted vocabulary as such (i.e., the variance common to both receptive and productive vocabulary measures) but by a hampered production of words (i.e., the variance common to both speed-of-naming and productive vocabulary measures.…

Relational knowledge of 21 derivational suffixes was investigated with 120 children (grades 3-8) and 40 adults. Results obtained from a nonsense-word model indicated that suffixes were comprehended with greater accuracy than they were produced, particularly by the children. Children and adults demonstrated greatest accuracy in comprehension and…

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…

Four nine year olds with mild mental retardation received training on the meaning of idiomatic phrases. All children demonstrated learning and an ability to understand the learned idioms when presented in unfamiliar contexts. Children were able to generalize their receptive learning to an expressive task with varying levels of success. (Author/JDD)

This study evaluated the relationship between the play behaviors of 18 deaf blind children (aged 3-12) and their communication skills using the Play Assessment Scale and several multidomain developmental checklists. Results revealed that behaviors observed during play assessment were highly related to ratings of receptive, expressive, and…

This study compared the science vocabulary performance of 76 students with learning disabilities (LD) and 78 normally achieving (NA) students at elementary and intermediate grade levels. Findings indicated significant differences in receptive language performance between LD and NA students and differences in expressive language between older and…

Twenty individuals (ages 8-18) with mental retardation and 20 controls matched for nonverbal mental age were assessed on receptive language level and nonverbal cognitive functioning. Results indicate that the nondisabled group placed less emphasis on the formal, sequential properties of language and more on semantic, conceptual properties.…

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…

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…

Describes how two teachers taught English Sign Language to 29 children (age 3) in a regular education preschool program which included 2 children with hearing impairments. When compared to 25 children who were not taught signing, the children who had been taught signing had significantly higher receptive vocabulary scores and were clearly superior…

Twenty-six children and adolescents who were unable to produce /r/ correctly listened to a tape of 200 words containing /r/ spoken, either correctly or incorrectly, by either the subjects themselves or another speaker. Subjects judged both the correctness of the /r/ and the speaker's identity. Results support a relationship between speech…

This study compared the language skills of low-birth-weight premature infants (N=11), higher birth-weight premature infants (N=14), and full-term infants (N=12) at 22 months corrected chronological age. Results suggest that low-birth-weight premature infants are at greater risk than higher birth-weight premature infants for speech and language…

Deaf children with signing parents, nonnative signing deaf children, children from a hearing impaired unit, oral deaf children, and hearing controls were tested on theory of Mind (ToM) tasks and a British sign language receptive language test. Language ability correlated positively and significantly with ToM ability. Age underpinned the…

A study compared 21 adolescent boys with Asperger syndrome and 21 controls and found significant differences between the two groups on measures evaluating social perception, social skills, number of close friends and frequency of contact, and social competence. There was also a significant difference on receptive language. (Contains references.)…
