REDINTEGRATION IN ALBINO RAT— A STUDY IN RETENTION 17 



where integration was difficult to establisli in learning a 

 similar difficulty appeared in redintegration trials after 

 retention. In other words, the weak link in the chain of 

 the habit, or the integration difficult to acquire, has appeared 

 after a retention period, although the weakness apparently 

 had disappeared after the long period of learning. 



Table I-B presents " errors," tabulated as in Table I-A,

but compares the total " errors " of redintegration with 

 the " errors " of the last 35 trials of learning. It was 

 hoped by summing these trials of learning that further 

 light on " dominance " would be obtained. The table 

 shows that dominance in later trials of learning, as a 

 whole, both in reference to complete learning and also 

 redintegration, follows closely what has already been noted. 

 It may be seen further that in some cases " errors " not
