50 WALTER S. HUNTER 



For further confirmation of the statements made above con- 

 cerning the general methods of delay, I shall present the rac- 

 coon Bob's record with the large release in some detail. Three 

 hundred and sixty trials were given on two boxes with this 

 release. Of the 27 reactions made with the wrong position and 

 correct orientation, 19 were correct. Of the 91 reactions made 

 with the right position and wrong orientation, 81 were correct. 

 Sixty -three times the reactions were preceded by positions and 

 orientations that were both wrong. There are two possibilities 

 here: (i) Orientation and position may favor the same box; 

 (2) they may favor different boxes. Forty of the 63 were reac- 

 tions of class I, i.e., were initiated by orientations and positions 

 that favored the same wrong box. Fifteen of the 40 were suc- 

 cessful. In other words, although both position and orientation 

 favored the same wrong box. Bob was able to overcome the 

 handicap and make 37% correct reactions. The remaining 23 

 reactions were of class 2. Of the 23, 16 were successful. Where 

 position and orientation were both wrong, but did not combine 

 to favor the same box, Bob made 69% correct reactions. Of 

 the 7 reactions of class 2 that failed, 5 were in accordance with 

 position and 2 in accordance with orientation, i.e., 5 times the 

 animal went to the box favored by position and the remaining 

 times to the one favored by orientation. 



In order that the reader may have a perfectly concrete presen- 

 tation of the reactions with the large release, I will quote a 

 day's record from the diary. The reactions were made at 8 

 sees, delay and with the exit doors from the light boxes, b and 

 c, open. In the records obtained with the large release, some 

 new symbols were used in describing the data placed in the
