An examination of tables 7 to 16 will reveal the fact 

 that there was positive transfer manifest throughout the 

 various series of maze-learnings with the exception of the 

 learning of maze D by groups 1 and 2, as judged by the 

 criterion of trials, the former group requiring an average 

 of 3.58 per cent more trials than did the control-group 

 upon this maze, and the latter requiring 12 per cent more 

 (Tables 7 and 8). 



In examining the records made by groups 1 and 2 in 

 maze D for the purpose of explaining these occurrences of 

 negative transfer, the outstanding fact brought to light is 

 that it is the number and persistence of errors made in 

 the first blind alley of maze D which account for the nega-
