Abstract
The existence of intra-uterine effects within the normal range of human intelligence was demonstrated. The effects of organic factors in the environment that are also pathogenic for intelligence were estimated. The combination of these and intrauterine effects is a substantial part of the variance associated with environmental factors. Implications are discussed.This publication has 1 reference indexed in Scilit:
