A list of words from Funk and Wagnalls' New Standard Dictionary was subdivided into 3 parts consisting of common basic words, rare basic words, and derivatives. Parts 1 and 2 have been standardized on various groups of college undergraduates. Standardization has been started with children in the first 8 grades of school. The average undergraduate in the groups used recognized 35% of the common basic words, 1% of the rare basic words, and 47% of the derivative words, representing a total of 155,736 words. Reliability estimates, intercorrelations for various scoring systems of the test, and correlations with other tests are given. Bibliography.

The possibility of selecting individuals best suited for training or work in practical motor skills is dependent upon: (1) the adequacy of job analyses, (2) the nature and persistence of individual differences in such skills, and (3) a measuring technique adapted to conditions outside the laboratory.The first step has therefore been an experimental analysis of eight serial motor performances on a group of fifty university men.(9) These tests ranged from speed of discriminative finger movement to accuracy in larger pursuit movements, and postural stability. The average inter-correlation of .25 indicates the specific nature of these performances and argues against the use of such terms as " general motor ability " or " general muscular coordination." For example, a person may rank consistently high on one skill such as a rotary pursuit arm movement at high speed and consistently low on others such as speed of turning a hand drill. Since the skills are independent it would be a mistake to say that a person showed " motor ability " because he ranked high on one or a group of motor tests.When fifty men were rated for amount of training in typing, instrumental music, and competitive athletics, it was found that the correlations of these types of training with the score on the
