Eighth test. No. 5 was used lustead of No. 4. No. 6 was uot at all 

 atteutive to No. 5. At times he watched the door when No. 5 went to the 

 button. He was not afraid of No. 5, so did not run away. No. 5 worked 

 rapidly and moved the button with wide movements of her arms. No. 6, 

 however, showed no interest in the button. 



When No. 5 was out No. 6 paid no attention to the button and but little 

 to the door. 



Ninth test. No. 6 was very indift'erent to the movements of No. 5 except 

 at the door. He often saw No. 5 get the food at the door and twice got food 

 there himself. The movement of No. 5 from the door to the button and 

 back to the door apparently meant nothing to him. 



When alone No. 6 worked intermittently at the door for ten minutes, but 

 did not notice the button. 



Tenth test. No. 6 saw five times in the twelve that No. 5 opened the door. 

 When No. 5 was removed No. 6 became busy at the door, but paid no 

 attention to the button during ten minutes. 



Summary of Behavior of No. 6 in the Button Experiment. 

 What No. 6 saw in the Button Experiment seemed to pi'ofit him nothing. 

 Once he repeated the movement of No. 4 in pushing back the button, but 

 he did not at that time nor later connect the button with the food door. At 

 no time did he give good attention to what was done in his presence, in the 

 ten tests seeing only fifty-one out of three hundred and three performances.
