KINAESTHETIC PROCESSES IN THE WHITE RAT 17 



it is all but impossible to set up a mere temporal sequence of 

 kinaesthetic processes with the rat. Running the spatial maze 

 therefore must require cues which have space location as well as 

 temporal position. In other words the rat must recognize in 

 terms of space where he is in the maze. These spatially located 

 cues may be anything but a kinaesthetic complex. This is not 

 to say that a characteristic kinaesthesis will not arise in certain 

 portions of the maze. It is to point out that the space location 

 of the kinaesthesis is due to non-kinaesthetic processes (contact, 

 e.g.). The present tests have indicated that the rat has prac- 

 tically no capacity to set up habits where the sensory complexes 

 succeed each other merely in tune. It is possible that a rat 

 might learn a space maze requiring simple alternation and then 

 run it in terms of kinaesthesis. The animal however easily mas- 

 ters the ordinary maze where the choices may be in any combi- 

 nation. How can it use the kinaesthesis connected with a left 

 turn at one time to initiate a turn to the right and at another 

 moment to initiate a turn to the left? Our tests have indicated 

 that this cannot be done unless spatially arranged cues are 

 available.
