PRIMACY IN THE LEARNING OF A PIG 65 



evening of the first day. On the second and third feedings he 

 ran directly to A without hesitancy. Each time, as soon as his 

 meal had ended, he was shut up in X. 



The food always, was put into the receptacle before the pig 

 was released so that he could not see it until he had crossed K. 



Second Day 



Fed every 2 hours. Food was put regularly into B. 



First feeding. When released the pig ran directly to A as 

 on the first day, not finding food he rambled about much dis- 

 turbed for several minutes. Finally he ran a little farther to 

 the right than before and found the food at B. 



Second feeding. The same procedure as in the first, but in 

 about half the time. 



Third feeding. He ran as before, directly into A; then 

 immediately to B. 



Fourth feeding. Same as third feeding, but in less time. 

 Each time when he had consumed the food at B he would return 

 to A looking for food there. He was never fed to satiety. 



Fifth feeding. Before he was released, a partition C, 8 inches 

 high was placed mid-way between the two feeding places. He 

 entered the A side directly then, with almost no hesitancy, 

 jumped over the partition toward B. There he was so dis- 

 turbed he did not get the food at B but jumped out over K. 

 After a number of quick false movements he jumped back over 

 K to B and ate the food. There was no more running to A 

 after the food was eaten. 



Sixth feeding. Jumped directly into the A side, came out 

 over K and with no false moves turned to the right and jumped 

 over K to B. 



Seventh feeding. Same as sixth. 



Third Day (Still fed at B) 



First feeding. He made a bee-line from O to A, back over 

 K, to the right, and to B over K. 



Second feeding. He made a bee-line for A but only raised 

 his head and looked over K, paused a few moments, turned 

 and jumped over K near partition, into B side. 



Third, fourth, and fifth feedings. Made a bee-line from O 

 to B.
