Haggerty, Imitation in Monkeys.

t^ II III mar 1/ of Behavior of No. 9 in the Paper Experiment. 

 During the five preliminary trials No. 9 gave the paper no attention. 

 The first test brought forth imitative behavior in that No. 9 put his hand 

 through the hole to get food after seeing No. 2 get food. After the removal 

 of No. 2, No. 9 pushed his hand up over the paper as if to tear it, a thing 

 he had not done in the preliminarj^ trials. The second test increased this 

 attention and after repeated fingering at the paper he tore it off and got 

 food. In the later tests he did not succeed in breaking through the paper, 

 but he repeated the movements of No. 2 and gave persistent attention to 

 the paper. His failure was possibly due not to the absence of the tendency 

 to imitate, but to the lack of muscular power to exert sufficient strength to 

 break the paper. 



General Summary of the Be suits of the Paper Experiment. 

 That the problem set in the Paper Experiment was one easy of 

 solution is evidenced by the fact that of eight animals all but three 

 learned it alone, most of them in the first trial. Of the three animals 

 which did not learn it alone two learned it by a process of gradual 

 imitation. The other one was never more than partially successful, 

 but his failure seemed due to a lack of physical strength rather than 

 to a failure to repeat the act which he saw performed.
