Greenberg, J. – Science News, 1985
Small family size has a number of apparently positive effects on a child's intellectual development. Discusses trends in Scholastic Aptitude Test (SAT) scores which strongly parallel changes in American family size. Intelligence Quotient (IQ) scores also reflect family size and parent education level; larger families correlate with lower IQs. (DH)

Peer reviewedZajonc, R. B. – American Psychologist, 1986
The confluence model shows the influence of family on intellectual growth. The decline of SAT scores is related to changing family patterns. Intellectual growth is lower for children with many siblings. The increase in average family size for the cohorts taking SATs between 1963 and 1980 caused scores to decline. (Author/VM)
