The Significance for Intelligence of Differences in Birth-Weight and Health within Monozygotic Twin Pairs.

Marsh, R. W.

British Journal of Psychology, v71 pt1 p63-67 Feb 1980

This paper presents further evidence to demonstrate the existence of intra-uterine effects within the normal range of intelligence. The argument is then extended further to estimate the effects of organic factors in the environment that are also pathogenic for intelligence. Various implications of these factors are discussed.
