PROCEDURE and SCORING, as in year VII, alternative 2.

REMARKS. The test is passed by approximately half of "average adults"

and by three fourths of "superior adults." It shows no effect of

schooling, the uneducated business men even surpassing our high-school


For the higher levels of intelligence, especially, the test is superior

to that of repeating digits in the direct order. It is less mechanical

and makes heavier demands upon higher intelligence.
