Examined the effectiveness of a nonbiased computerized language screening test, the Kidtalk Interactive Diagnostic Test of Aptitude for Language Knowledge (KIDTALK), in differentiating children on basis of diagnostic category but not ethnic/linguistic background. Found a significant difference between scores of the language learning disabled and non-language learning disabled participants, no difference between Anglo/English-speaking and Hispanic/Spanish-speaking groups, and no interaction effect.
