Remarks. The words of each series lend themselves readily to classification into a next higher class. This is the best type of response, but with most of the series it accounts for less than two thirds of the successes among subjects of 12-year intelligence. The proportion is less than one third for subjects of 10-year intelligence and nearly three fourths at the 14-year level. It would be possible and very desirable to devise and standardize an additional test of this kind, but requiring the giving of an essential resemblance or classificatory similarity.
For discussion of the psychological factors involved in the similarities test, see [VII, 5].
