(introductory text...)

In the first section of this chapter, we review the issues that were discussed in Chapters III and IV, with a particular focus on whether the differences in the cognitive functioning of the Atole and the Fresco groups are best explained by the difference in the nutritional history of the subjects. The second section is devoted to a discussion of the results of the analyses of the psychoeducational and information-processing data. We then present a theoretical interpretation of the findings and, finally, consider their programmatic implications.
