Abstract
BIRTHDAYS IN RELATION TO INTELLIGENCE.—In the Proceedings of the Royal Society of Edinburgh (vol. 41, No. 17) Mr. M'Callum Fairgrieve discusses the annual incidence of intelligence. He experimented with 368 boys, using chiefly the American Army tests, supplemented by some of the tests used by Dr. Cyril Burt. His object was to see whether the time of year of birth bore any relation to intelligence. The results seem to show that boys born in the late spring months are in danger of developing less intelligence than those born about October. It is pointed out that naturally there are exceptions, some of the clever boys having birthdays in the less intelligent period, but that on the whole, and his ages range from ten years to eighteen years, the generalisation is correct. The author suggests that it would be valuable if the test were repeated in other districts. Certainly it is a problem worth studying systematically.
