harder maze, judging both by the average total errors and 

 the average total time per rat and by the average number 

 of errors and the average time per trial; and the saving 

 in time was less than the saving in one of the transfers 

 from an easier to a harder maze, according to the average 

 total errors and average total time per rat, and less than 

 the saving in two of these transfers, according to the average 

 number of errors and the average time per trial. 



TABLE 4 



Percentages of Savings in Transfers from Less Difficult to More Difficult 

 AND FROM More Difficult to Less Difficult Mazes, on the Basis of 

 THE Average Total Errors and Average Total Time per Rat 



Percentages of Savings in Transfers from Less Difficult to More Difficult 



AND FROM More Difficult to Less Difficult Mazes, on the Basis of the 



Average Number of Errors and the Average Time per Trial 



From the Less to the More Difficult From the More to the Less Difficult 



Trials Errors Time Trials Errors Time 



From A to B... 59 70 88 From B to C... 33 33 78 



From C to D... 27 37 41 From D to E... 65 77 69 

 From E to A . . . 20 53 86 

 From E to D... 15 46 40 



It will be seen from the figures in tables 4 and 5 that, 

 although the average savings are higher when the transfer 

 is from the harder to the easier maze, there is no ground 

 for the statement that these savings are in every instance 

 higher than when the transfer is from the easier to the 

 harder. The transfer from the easier to the harder may 

 be greater, as we may . note by comparing the transfer 

 between A and B with that between B and C.
