This study compared differences in preschool children (n=201) clinically diagnosed with specific language impairments (SLI) who were and were not identified through standard psychometric discrepancy criteria. A combination of mean length of utterance, percent structural errors, and chronological age was found to be more useful for predicting a…

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)

Because eligibility for speech-language services often is based on the relationship between the child's cognitive ability and language performance, this study examined the agreement of measurement practices used in the cognitive referencing model of eligibility determination. Administration of 5 measures to 26 preschool children with delayed…

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…

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 compared 4 methods (2 case history and 2 performance-based) used to classify the status of adult subjects in familial studies of developmental language disorders, involving 24 parents of children with developmental language disorders and 24 unrelated adult controls. Classification by case history found fewer affected adults than…

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…
