TRANSFER OF RESPONSE IN THE WHITE RAT 59 



Summary Showing Effect of Transfer 



Trials Series 



Average for learning Light, Normal Record found 198.87 13.26 



Gained by direct transfer from Sound 48.87 3.26 



Gained by transfer with two simultaneous series 78.87 5.26 



Gained by transfer with four simultaneous series 93 . 87 6 . 26 



Little need be said here except to call attention to the 

 fact that even in learning the response to the light which 

 proved to be very easy for the animals, there was an advan- 

 tage in first learning the same response to some other sort 

 of stimulus. As in the series previously reported a few 

 series with the two stimuli simultaneously given overcame 

 almost entirely any loss there happened to be by passing 

 directly from learning the one to learning the other. 



(4) Sound to Pain — Three groups of animals were 

 trained with the sound and transferred to the pain. Group 



XVII was transferred directly from sound to pain. Group 



XVIII was given two series of simultaneous sound and 

 pain after learning the response to the sound and then 

 were transferred to the pain. Group XIX was given four 

 series of simultaneous sound and pain after learning the 

 response to the sound and then were transferred to the 

 pain. The results are gathered together in the tables 

 given below. Illustrative curves are to be found on page
