272 LINUS WARD KLINE 



the distributing position made the movements at as uniform rate 

 as possible (about one movement every two seconds) in the 

 order and manner similar to a regular trial and reported its 

 feeling quality as soon as executed. The subjects without ex- 

 ception conceived the movements as being made on a vertical 

 plane, similar to that of the case, and as consecutive from box to 

 box beginning with the Q of C and ending with the A of H. 

 The results of the " memory report" 3 of the feeling tone of move- 

 ments do not appear in table 3. 



In the earlier periods of the practice, the left hand remained 

 comparatively stationary, holding the pack, while the right hand 

 performed in order the operations of " going, " " taking," " fetch- 

 ing" and " tossing." But from the fourth to the eighth period 

 "going" and "fetching" were eliminated by most of the subjects, 

 and the left hand was trained to move in unison with the right 

 and to serve it with a card at the proper receiving box. As ex- 

 pressed by one of the subjects, "The left hand became a bag- 

 gage car for the right." Besides, the left thumb was trained to 

 feed the cards one at a time to the thumb and forefinger of the 

 right hand. This reduced the work of the right to "taking" 

 and "tossing." Here again the individuality of the subjects 

 became pronounced through the skill and rate with which the 

 superfluous movements were eliminated. 



3. The third group of subsidiary results, to appear in a sepa- 

 rate paper, consists of answers made by the "receiving" and 

 the "distributing" mail clerks to a questionary sent to 22 post 

 offices in the larger cities of the United States. Some 320 

 copies of the questions were distributed and from these 180 

 apparently reliable answers were received. 



DISCUSSION OF RESULTS 



A. The acquisition of skill in card-case distribution 



Since the learning process is here used as a method for deter- 

 mining the nature of the relations between the acquisition of 



3 The "memory report" of the feeling qualities of movements runs strikingly 

 parallel with that of the "perceptual" or actual report.
