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. 1 took up the various associations was 
AA, BB, BBzr, G, N, CC, II, 0. 
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 0 out of 2 (that is, without previous experience 
of AA). 
In CC 1 out of 2. 
In II 3 out of 3. 
In M 1 out of 2. 
In N 1 out of 3. 
In G 1 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
