Experimental Study of Associative Processes 85 
imitators, of course, had previously failed to form the asso- 
ciation of themselves. F denotes failure to perform the act:

Thus out of all these cases only one did the act in spite of 
the ample chance for imitation. | I have no hesitation in 
declaring 82’s act in stepping on the platform the result 
of mere accident, and am sure that any one who had watched 
the experiments would agree.| 
IMITATION IN CaTs 
By reference to the previous descriptions of apparatus, it 
will be seen that box D was arranged with two compart- 
ments, separated by a wire screen. The larger of these had 
a front of wooden bars with a door which fell open when a 
string stretched across the top was bitten or clawed down. 
The smaller was closed by boards on three sides and by the 
wire screen on the fourth. Through the screen a cat within 
could see the one to be imitated pull the string, go out
