34 INDIVIDUAL DIFFERENCES AND FAMILY RESEMBLANCES 



The results of the present investigation agree with those found by 

 Yerkes concerning his discrimination test, but do not agree with his 

 results for the labyrinth test. The multiple choice used in the pres- 

 ent experiments was primarily designed to test discrimination, while 

 tending to destroy position habit, and so it may be considered com- 

 parable to the discrimination test used by Yerkes. Here there is 

 agreement, in that the males did better than the females, but in the 

 maze test, which corresponds to Yerkes' labyrinth, the results of this 

 investigation agree with Hubbert 's and disagree with those of Yerkes.
