TIME VERSUS DISTANCE IN LEARNING 69 



of accuracy, to base comparisons upon the time alone than to 

 consider these so-called errors. As to which type of record is 

 best, time or distance, it seems wise to await a more complete 

 study of the question before deciding. 



CONCLUSIONS 



I. It is possible to chart the path of the run of an animal 

 through the maze and to measure accurately the total distance 

 covered in that run. 



II. Time and distance curves are so similar in character when 

 normal animals are tested that it is impossible to state which is 

 the better criterion of learning. We are sadly in need of a close 

 analysis of just what time and distance curves mean. In deter- 

 mining the activity at different ages, the difference between 

 blind and normal animals, between anosmic and normal animals, 

 etc., there still remains the possibility that the distance and 

 time curves will show great disparity. It is not fair, however, 

 to maintain this until there is some factual evidence in its favor.
