The Use of an Invented Language Rule in the Differentiation of Normal and Language-Impaired Spanish-Speaking Children

The purpose of the present study was to determine whether the results of a language-teaching procedure could be used to identify specific language-impaired children in a group of bilingual children with limited English proficiency (LEP). An invented morpheme was taught to two groups of LEP children who had been previously identified as normal and specific language-impaired. The language-impaired group learned the morpheme at a slower rate than the normal children, thus allowing the two groups to be differentiated. The approach promises to circumvent many of the obstacles that impede current practices for identifying language impairment in the LEP population.
