ROLES OF HEREDITY AND ENVIRONMENT IN INTELLECTUAL DEVELOPMENT

[摘要] The Interesting yet controversial article by Knobloch and Pasamanick in this issue of Pediatrics throws additional, and badly needed, scientific light on four hotly disputed issues of intellectual endowment and development.1) Race: The Knobloch-Pasamanick data demonstrate that, during infancy (approximately the first year of life), there are no Negro-white differences in developmental quotients, if circumstances of pregnancy-history, birth-weight, and rate of physical development are evened-out statistically.2) Socioeconomics and race: Differences, when found, are more reasonably accounted for by socioeconomic status than by race.3) Reliability of tests in infancy: The paper presents data sharply at variance with those existing in the literature concerning tests available for infants.
