Neurological status of language-impaired and normal children.

The performance on a neurological test battery of 33 language-impaired children who had no gross neurological findings and 37 normal children controlled for age, performance IQ, and socioeconomic status was compared. The language-impaired group was distinguished by less efficient performance in a number of areas, particularly in tasks involving involving rate of movement, perception of dichhaptic stimuli, and left-right identification. Discriminant function analysis identified six variables that correctly classified 87% of the population into their respective normal and language-impaired groups.
