Over het intelligentie-onderzoek bij de militaire keuringen vanaf 1925 tot heden

Samenvatting

Since 1925, Dutch military recruits have taken intelligence tests. Analysis of official data from 1925, 1932, 1952, 1962, 1972, & 1982, using r coefficients, shows that as the general educational level of the country has increased, so have the raw scores on the intelligence tests. 11 Figures, 2 Appendixes, 18 References.
