This study evaluated an Extended Optional Infinitive theory of specific language impairment (SLI) in children, which suggests that SLI children omit finiteness markers longer than do normally developing children. Comparison of 18 SLI 5-year olds with 2 normally developing groups (ages 5 and 3) found that SLI subjects omitted finiteness markers…

This study examined test characteristics of the Pediatric Language Acquisition Screening Tool for Early Referral-Revised (PLASTER-R), a set of developmental questionnaires for children 3 to 60 months of age. The PLASTER-R was moderately to highly successful in identifying children within normal limits for language development. Test-retest…

This article describes errors resulting from use of standardized language tests using a "normal" sample as the normative comparison group. Resulting errors include, among others, identifying normal children as language impaired, providing misleading profiles of verbal and nonverbal performance, and inability to determine impairment severity.…

This study compared four commonly used vocabulary tests to screen or identify preschool children for specific language impairment (SLI). Four- and five-year olds with (N=31) and without (N=31) SLI were compared on the tests. Despite moderate to strong inter-test correlations, no test was a strong identifier of SLI. (Author/DB)

This investigation compared the performances of 24 African American children (mean age 6) with language impairments (LI) to typically developing African American peers on five traditional informal language assessment measures. Performances of the LI children were significantly lower on all measures than typically developing peers. Implications for…

This article describes the EpiSLI diagnostic system for identifying specific language impairment in kindergarten children for the purpose of epidemiological research. The system employs five composite scores representing norm-referenced performance in three domains of language (vocabulary, grammar, and narration) and two modalities (comprehension…

Systems for classifying speakers' communicative intents are typically limited in scope, in applicability across the full developmental range of language abilities and disabilities, and in their theoretical foundations. Criteria for an adequate system for analyzing communicative intents are discussed, and a system is proposed which meets those…

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…
