Possibly no one realizes more fully than the experimenter 

 certain crudities of method in this experiment, but still there 

 are some things of interest to the animal psychologist. And 

 if any conclusions may be drawn from the use of so few animals 

 those conclusions are in accord with previous findings in the 

 dancer. 



Conclusions. 1. The rapidity with which kittens acquire the 

 habit of always choosing the light box may be seen from the 

 following results: Under fairly difficult conditions of learning, 

 with a medium stimulus it took on the average 82.5 trials for 

 the kitten to perfect a correct habit, and with a strong stimulus 

 107.5 trials; under less difficult conditions it took 60 trials with 

 a medium stimulus, and 55 trials with a strong stimulus; and 

 under fairly easy conditions it took 75 trials with a weak stim-
