Summary of Behavior of No. 6 in Chute Experiment B. 



No. 6 differed from each of the previously mentioned animals in his pre- 

 liminary trials. He gave some attention to the end of the chute, on the 

 second day, putting one hand into the end of it a short distance. On the 

 later days, however, he ignored the end of the chute entirely. The stimulus- 

 complex in the first test was the same as in the case of No. 13, namely, 

 the sight of another animal performing an act and getting food thereby. 

 The effect on No. 6 was evident, for within thirty seconds after being released 

 in the cage he had repeated a part of the act he had seen ; within a minute 

 he had tried again and repeated the act in every particular, except in the 

 amount of force witli which he pulled. This difference, however, kept him 

 from getting the food. Although he failed, he repeated the act entire or in 

 part several times during the next few minutes. 



After his second series of observations, lie repeated the entire act again, 

 but failed to exert sutficienl strength to accomplish the result. During the 

 succeeding tests he persisted in going to the chute, although he ceased to 

 pull the string. He did not cease to investigate the inside of the chute with 

 eyes and hands, although his only means of connecting the chute with food 

 liad been his observation of another animal getting food at the chute.

G. Behavior of No. 5. 

 Preliminary trials.^First trial, July 30. — Within one minute after entering 

 the cage, No. 5 had climbed to the chute and had found the string with 

 her hand. She was able to reach the chute from the side of the cage by 

 help of her long legs and tail, which supported her wliile she grasped the 

 chute in her hands. Later she reached the chute from the end of the cage. 

 Then she swung to it from the side and looked up at the end. She then 

 tried to use her foot to pull the string, and failing, climbed up the chute 

 and examined the top of the cage. Then she braced her feet against the
