U stimulus is more effective in this respect. There is but slight 

 evidence that U stimulus affects in any way the growth of motor 

 skill. 



2. No statement can be made here concerning the effect of 

 tense and relaxed feeling qualities on the integrating processes, 

 although tense feelings were present more or less throughout the 

 practice, but in many instances gradually faded with achieve- 

 ment. 



3. Movements regardless of direction and of extent, but bear- 

 ing cards for substitution, were more likely to be considered un- 

 pleasant than those bearing " resident" cards. The feeling ex- 

 cited by the cumulative effect of two successive substitutions 

 became attached to the kinaesthesis of the movement for which 

 the substitution was made and it was ascribed by the subject to 

 the movement itself. It even affected in some instances the nor- 

 mal part of the distribution (club to club boxes and heart to 

 heart boxes). There seems to be no doubt but that the feelings 

 thus excited delayed the integration of the movements. How 

 much of the delay was due to the feelings per se and how much 

 to inhibitions caused by the clash between old and new associa- 

 tions could not be determined. 



4. The feeling qualities aroused by the apparent conflict of 

 the kinaesthesis, conditioned by critical movements, interfered 

 with the rate of learning. Here as in "3," the question as to 

 how much of the handicap was due to the conflict of kinaesthesis, 

 and how much to feelings excited thereby could not, under the 

 conditions of the experiment, be evaluated. 



5. The U and P feelings excited by the moving arm in attempt- 

 ing skilful movements exerted a decided influence on the processes 

 of integration. This conclusion is reached from two different 

 sources of evidence: (1) The U feelings aroused by substitution 

 of suit checked the learning and thus proved that feelings grow- 

 ing out of the learning process affected it. (2) The decided 

 inverse correlation between P feelings and inhibitions and the 

 positive correlation between U feelings (aroused by movements 

 being integrated) and inhibitions.
