number of errors, yet this is probably not sufficient to account 

 for the result since the speed was less in cases where there were 

 no errors. The slower speed was caused, perhaps, by a natural 

 hesitation because of the attractiveness of the errors and this 

 was made possible by the slighter kinaesthetic automatism. 



Our final conclusion is then that if animals are given two 

 contrasting paths side by side, differing in brightness, the one 

 path may prove more dominant and favor accuracy and because 

 of accuracy a shorter time in the early trials. After the problem 

 is learned, in the slow turning over to kinaesthesis, when atten- 

 tion is freed, these sensory factors may still retain their potency 

 in times of momentary distraction. The result is a less perfect 

 automatism and a slower speed.
