Economic advantage and the cognitive ability of rural children in Zaire.

Rural Zairian children (n = 32), 4 to 6 years old, were enrolled in a preschool educational and nutritional enrichment program throughout the school year. As part of the evaluative research for this program, cognitive and motor development of the children was assessed with the American Guidance Service (AGS) Early Childhood Screening Profiles (ECSP; Harrison et al., 1990) battery, adapted to the local Bantu dialect of Kituba. On the ECSP global indicator of cognitive ability, the children in the enrichment program performed significantly better than their counterparts in nearby villages, although the two groups did not differ significantly on motor development or anthropometric indicators of physical development. The results indicate that rural African children with reasonable nutritional status demonstrate significantly improved intellectual development in response to a comprehensive economic enhancement and educational enrichment program for them and their families.
