... itions demanding maximal attention ; ability to divide attention or rapidly to alternate it; ability to understand spatial relations or to introduce order into one's spatial perception; and ability to comprehend conceptual relations. In all save the tests of rapid movement, the children of the "better class" were strikingly superior. Contents I. Aim of investigation and selection of tests. II. The children investigated. III.
