HABIT FORMATION IN THE ALBINO RAT 



49 



To test the matter, six rats of the sixty-five day group were 

 kept at work for more than one hundred sixty trials after learn- 

 ing was complete, the average time for each six trials was com- 

 puted and appears in Table XI as twenty-seven tests. Taken 



e = Error 



* = Lowest record for individual rats 



t = Lower record than absolute time value for certain rat 



The dotted line divides the table into first and second halves in order to make 

 comparison of the two stages easier. The number of errors made by each rat in 

 each half is shown. 



individually the results show that in every case a lower record 

 than the absolute time record was made, but in no case main- 

 tained. If the group average be noted, the absolute time is 

 never quite reached, the curve (Fig. 8), starting a little above
