EFFECT OF LENGTH OF BLIND ALLEYS ON MAZE LEARNING 13 



animal would stop quickly at the entrance to a blind alley while 

 the head would vibrate very rapidly between the direction of 

 the true path and that of the tempting by-way. The record 

 here and there shows, for instance, that an animal would stop 

 at cul de sac 1, after having nearly inhibited the tendency to 

 enter this blind alley, and make, say, three double vibrations 

 (3 v. d.) with the head. This behavior is very suggestive and 

 will be considered later. On the whole it was found that the 

 full description of the animal's behavior was much more valuable 

 for the present problem than the mere recording of time and 

 errors. Time records were, however, also kept.
