This bibliographic review aims to present a single comprehensive source of references to facilitate clinical application of data obtained on the vocal activity of normal infants and to facilitate continued research on prelinguistic vocal output. The bibliography cites the published observational, empirical, and theoretical reports that examine the…

Four developmentally delayed preschoolers were taught action-object responses in receptive and expressive language modalities, using matrix-training procedures. Acquisition of a word combination rule was facilitated by the use of familiar lexical items, whereas subsequent acquisition of new lexical knowledge was enhanced by couching training in a…

The Denver Developmental Screening Test (DDST) and an expressive language measure were administered to 114 children (aged 24 to 74 months) suspected of developmental difficulties. The DDST did not identify the majority of children who failed the expressive language screening, even after cutoff scores were made more rigorous. (Author/JDD)

Sampling spontaneous expressive language through video narration is offered as a means of reducing variability among language samples over time or from different speakers. Advantages include content stability, high interest value, and high processing demands. Disadvantages include brevity of the samples, lack of information on dyadic communication…

This study evaluated 9 computer-generated measures of children's language production, based on 24 children with specific language impairment and 24 normally developing children, ages 24-50 months. Three measures possessed desirable developmental and diagnostic characteristics: mean syntactic length, total number of words, and number of different…

This study, involving 20 children (ages 4-11) with severe hearing impairments, affirmed the content validity of the Clark-Madison Test of Oral Language as a measure of nonwritten expressive language with hearing-impaired children. Performance comparison with hearing individuals revealed a different profile of strengths and weaknesses than did…

This study explored effects of training 25 mothers to administer focused intervention to teach specific target words to their toddlers with expressive vocabulary delays. Following treatment, mothers' language input was slower, less complex, and more focused. The children used more target words, more words during play, and had larger vocabularies…

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…

This study examined the temporal reliability of four quantitative measurements of linguistic behaviors in 20 preschool children observed in a naturalistic setting. Although inadequate reliability was found for the measure which used total number of words, very high reliability coefficients were obtained for the measures which used number of…

Eighteen preschoolers with language impairments who had participated in a highly effective five-month intervention that focused on expressive grammar received an additional five-month intervention. Although participants improved during Phase 2, improvements generally were not as strong as those noted for Phase l. The costly clinician-administered…

Comparison using paired t-tests of parent and teacher ratings for 16 preschool children on the Receptive-Expressive Emergent Language Scale found no significant differences between parent and teacher ratings of expressive language, but a significant difference on the receptive language subscale. However, interrater reliability was relatively low…

This study evaluated the validity of language-assessment instruments with Native American children, ages 3 to 5. Results indicated that the Preschool Language Scale-3 provides a valid assessment of the receptive and expressive language skills of 3- and 4-year-old Native-American children. However, use of this scale with 5-year-old Native Americans…

Thirty-six children, aged four-five, completed four vocabulary measures: Peabody Picture Vocabulary Test-Revised, Picture Vocabulary subtest of the Test of Oral Language Development, Expressive One-Word Picture Vocabulary Test, and Receptive One-Word Picture Vocabulary Test. Only moderate correlations were found among these tests, implying that a…

Ten two-year-old children with periventricular leukomalacia (PVL), a brain injury associated with prematurity, were evaluated using language samples. The five children with delayed cognitive ability produced significantly fewer lexical tokens and spontaneous verbal utterances than did chronological age-matched nondelayed PVL children. (Author/DB)

This study examined the relationship among language proficiency, behavior problems, and other areas of development in 36 children (ages 36 to 40 months). A strong association was found between deficiencies in both expressive and receptive language and behavioral difficulties. Specifically, deficits in expressive language at age 2 were more…
