Neuropsychological deficit, ethnicity, and socioeconomic status.

The results of a community study dealing with the ecological distribution of intellectual and various perceptual-motor deficits, presumed to be functionally related to neurological status, are presented. Ss were 158 White and 60 Black 3rd graders of public and parochial schools. Measures included a parents' questionnaire, school achievement data, behavioral ratings, and such tests as the Culture Fair Intelligence Test, Wepman Auditory Discrimination Test, and the Bender Gestalt Test. Results suggest that levels of neurological integrity vary along a socioeconomic gradient and between ethnic groups. An environmentally based model of social causation is presented as the most appropriate explanation of the patterned distribution of neurological pathology across social class and ethnic-group lines. This model focuses on such factors as malnutrition/undernutrition, adverse conditions of environmental stimulation, inadequate obstetrical and pediatric care, and environmental deterioration.
