We studied the relation between intellectual performance, family size and birth order. According to Zajonc's confluence model, we expected a decreasing performance with both family size and birth rank. Subjects were 893 students from technical high schools, aged from 15 to 18.

Students living in a one to three children family performed better than those living in a four or more children family. Within these two populations there is no relation between family size and performance. Family size and intellectual performance are discussed as related aspects of a whol...
