220 Animal Intelligence 



through the act) would be put where he could see another 

 do the act and get a reward (food) for it. He would then be 

 given a chance to do it himself, and note would be taken of 

 his success or failure, and of whether his act was the same 

 as that of his model in case he succeeded, and of whether he 

 tried that act more than before the tuition in case he tried 

 it and failed. The results are given in Table u. 



In the fourth experiment No. i showed further that the 

 tuition did not cause his successes in that after some suc- 

 cesses further tuition did not improve him. 



There is clearly no evidence here of any imitation of No. i 

 by No. 3. There was also apparently nothing like purposive 

 watching on the part of No. 3. He seemed often to see No. 

 i open the box or work the chute mechanism, but without 

 special interest. 



This lack of any special curiosity about the doings of their 

 own species characterized the general behavior of all three of 

 my monkeys and in itself lessens the probability that they 

 learn much from one another. Nor did there appear, in the 

 course of the three months and more the animals were to- 

 gether, any signs of imitation. There were indeed certain 

 notable instances of the lack of it in circumstances which 

 one would suppose would be favorable cases for it. 



For instance : No. 2 was very timid. No. i was perfectly 

 tame from the first day No. 2 was with me, and No. 3 be- 

 came tame shortly after. No. 2 saw Nos. i and 3 come to me, 

 be played with, fed and put through experiments, yet he 

 never did the same nor did he abate a jot or tittle from his 

 timidity save in so far as I sedulously rewarded any chance 

 advances of his. Conversely No. i and No. 3 seemed un- 

 influenced by the fear and shyness of No. 2. No.2's cage 

 was between No. I's and No. 3*3, and they were for three 

 weeks incessantly making hostile demonstrations toward
