 random movements were eliminated except a little push at n ; 

 the route chosen was direct. 



One important conclusion, I think, is that the path was 

 not learned by tracking, i. e., that smell did not enter into the 

 formation of the association. 



The slow disappearance of random movements suggests 

 that kinesthetic sensations are an important factor in learning a 

 path, though that the}' are not the only factor is shown by the 

 elimination of unessential movements, indicating that something 

 beside mere sequence of sensations enters into the association. 



Test V. Complexity of associations. 



The most difficult labyrinth experiment which was to be 

 presented to the adult was now presented to the three days old, 

 in order to determine how complex a path could be learned.

As usual the labyrinth was made entirely of wire. A, B, C are alleys from 

 which there is no exit. The entrance to the wire box, X, is very small and is 

 open. 



Care was taken to have the whole cage free from any odor. 

 The mother was placed at X and the little one at Y. 



Time for finding the mother in the first trial was 5.166 

 min.
