DELAYED REACTION 45 



animal held for lo sees. During this delay, Jack turned toward 

 all three boxes. No observable part of his body remained con- 

 stant. At the instant of relea-^e, he was headed toward the 

 proper box, a, and reacted correctly. On the 5th trial, Jack 

 was oriented toward the middle box, b, at the moment of release. 

 He went to a. then to b, then to c and back to the experimenter 

 for food. The reaction had failed. If to the large number of 

 correct trials made with wrong orientations be added the correct 

 trials made with correct orientations that had been completely 

 lost and then refound, the number of reactions significantly 

 different from those of the rats and the dogs reaches relatively 



huge proportions. 



TABLE X 



Two other types of reaction remain to be indicated in the 

 above table, (X). Orientation b was held 6 times; orientation 

 a, 7 times, and c, twice. Yet different correct reactions followed 

 from the same orientations. Jack was oriented to c once and 

 went to b correctly. The next trial he had the same orientation 

 and went to a correctly. In neither case had he seemed to 

 keep any part of his body constant. In the 4 correct responses 

 to the light box b, the corresponding orientations were as differ- 

 ent as possible. Twice Jack was oriented to a and once each 

 to b and c, yet each time the correct reaction was made. In 

 other words, the same orientation did lead to different reactions 

 and different orientations to the same reaction. These, again, 

 are types of behavior never met with in the rats and dogs. This 

 behavior occurred so frequently with Jack and with Bob—
