of the experimental session would be a relative^ insignificant addition 

 to the sum of past experience. In only one subject does the effect of 

 repetition approximate 10 per cent in this measurement, and that is the 

 case of Subject VII, a native German with noticeable limitations in 

 his use of English. 



Practically as satisfactory in this respect for the main group of 

 subjects was the reciprocal innervation of the finger. Its average 

 practice change in these experiments was 4 per cent.
