REDINTEGRATION IN ALBINO RAT — A STUDY IN RETENTION 65 



establishment of a habit, yet by the three trials per day 

 method perfect integration is more difficult at the locus 

 of dominant " error." Such a method is absolutely more 

 economical in learning, retention, and redintegration, but 

 is relatively less economical during retention and integra- 

 tion than it is in the process of learning. 



8. The learning of another problem during the period of 

 retention, before giving redintegration series, does not result 

 in a loss of redintegration; that is, the acquisition of a 

 second habit does not produce distrubances in the organism 

 which might interfere with redintegration tests for the first 

 habit established. 



9. Previous training improves subsequent learning and 

 redintegration. The condition of the organism is in many 

 ways superior after a period of training.
