Summary of Behavior of No. 5 in the Rope Experiment. 

 Like No. 4 and No. 6, No. 5 had to learn to open the door only. In the 

 first test her attention was directed to the door; she went to it, nosed 

 about it and put her hand on the door. The second test did not add any- 

 thing to her learning, but in the third test she repeated her behavior of 

 the first test. The fifth test added nothing to her ability, but in the sixth, 

 when she was free in the cage with No. 6, his conduct directed her attention 

 to the food door and kept it there until she had learned to get food. At no time 

 did she get food for herself in connection with the performance of No. 6, 

 and the stimulus was never more than No. G performing an act and getting 

 the result. 



General Summary of the liesults of the Rope Experiment. 



Considering together the four animals used in the Eope Experi- 

 ment we may note a similarity in the general behavior. First, no 

 animal failed to learn. Second, in the j^reliminary trials there was 

 a total indifference to the food door and either total or increasing 

 inattention to the rope. Third, without exception, the first imita- 

 tion test served to direct attention to the door and to the rope. In 

 the case of ISTo. 6, imitation was complete in the first test. Fourth, 

 in the cases in which imitation was not complete in the first test, 

 the successive tests augmented the imitator's attention and in no 

 case were more than six tests needed to perfect the learning process. 



Here, as in the chute experiments, we have attentive watching on 

 the part of the imitating animals, followed by an abrupt and radical 

 modification of behavior in the direction of the act observed. This 

 is imitation as we have defined it.
