Changes in Intelligence over a Quarter of a Century.
Emanuelsson, Ingemar; Svensson, Allan
Scandinavian Journal of Educational Research, v34 n3 p171-87 1990
Using data from the Swedish Individual Statistics Project, changes in intelligence among 13-year olds are documented over a 25-year period. The average spatial and reasoning intelligence has risen successively. A clear increase is found for verbal intelligence in the 1960s, with more irregular growth since then. (SLD)
