Experimental Study of Associative Processes 61 



The curves on page 60 are to be interpreted in the same 

 way as those for the cats, and are on the same scale. The 

 order in which No. i took up the various associations was 

 AA, BB, BBi, G, N, CC, II, O. 



The percentage of dogs succeeding in the various boxes 

 is given below, but is of no consequence, because so few 

 were tried, and because the motive, hunger, was not perhaps 

 strong enough, or equal in all cases. 



In AA 3 out of 3. 



In BB o out of 2 (that is, without previous experience 

 of AA). 



In CC i out of 2. 



In II 3 out of 3. 



In M i out of 2. 



In N i out of 3. 



In G i out of 3. 



EXPERIMENTS WITH CHICKS 



The apparatus was as follows : 



P was simply a small pen arranged with two exits, one 

 leading to the inclosure where were the other chicks and
