308 LINUS WARD KLINE 



order of the boxes visited in delivering a suit were C, C, D and 

 H. The evidence, to be submitted below, shows that even the 

 distribution of the hearts was affected by the cumulative effects 

 of the double substitution. A study of the reports on the feeling 

 qualities of movements shows that the number of U (marked 

 in table 3) movements made in delivering cards requiring sub- 

 stitution exceeded the number of unpleasant movements with 

 cards not requiring substitution. A numerical comparison of 

 the averages of the percentages of the U reports of plans I and 

 II, table 3, including the movements listed under both " series" 

 and "individual," shows 25.7 per cent and 25.5 per cent for 

 these two sets of reports unaccompanied by substitution of suit, 

 and 16.7 per cent and 18.8 per cent for the two sets ("series" 

 and "individual") not involving substitution. 



While these results offer ample evidence of the burden involved 

 by substitution and caused the subjects to regard such move- 

 ments as unpleasant, yet the unpleasantness was not due to the 

 movements as such. 



Second. Feeling tones grew out of the confusion arising from two 

 divergent movements. The conditions of plan I required two 

 diverging movements from club boxes to club and to diamond 

 boxes, respectively. Diagram 3 shows 13 such diverging points, 

 already described as "critical" points. A critical inspection of 

 this diagram shows the problems and difficulties encountered. 

 Also the movement from club to club box carrying either a 

 diamond or a club was often checked at the second visit by find- 

 ing a club or a diamond already there. This proved disconcerting. 



At the 5P, G points out that at that time he knew more . 

 diamonds than heart boxes, but that an unknown heart box was 

 easier to locate than an unknown diamond box. 



Other subjects of plan I found the same thing. Some made 

 exceptions of 7 of H, 5 of H and 3 of H. Comparatively hearts 

 gave little or no trouble at first, but as the movements began 

 to form orderly sequences, the cumulative effects of spade to 

 diamond and diamond to club already described began to operate 

 adversely on hearts. I interpret this as a delicate instance of 

 the effect of feeling tone postponing the learning process.
