Abstract
In investigating the effects of chronic, subclinical undernutrition on psychological development, 87 coloured preschool children were classified as undernourished or well nourished on the basis of anthropometric measures, dietary intake and maternal stature, and a comparison was made of their scores on the Revised Denver Developmental Screening Test. An assessment of each child's developmental history, the nature of the caregiver—child interaction, and the home and social environment, was made. Significant differences were found between the two nutritional groups regarding language development only, and the explanation is believed to be social rather than physiological. It was concluded from the analysis that this form of undernutrition does not have a large direct impact on development separate from the influence of environmental factors.
