sess the power to make rudimentary distinctions between the 

 color, this function is a highly unstable one and cannot be 

 supposed to play a part in the normal life of the dog. Fuither- 

 more, even when discrimination among the colors has been 

 established, it may be lost easily through differences in lumi- 

 nosity and position. 



AUDITION 



Mammals. Shepard (22) finds that the cat discriminates 

 articulate sounds, responding to its own name. The experi- 

 menter was in plain sight of the animal during the entire time 

 of observation, sitting about a meter away in front of the cage. 

 He worked with two cats. The name -reaction demanded in 

 one case was the rearing up of the animal against the cage; 

 while in the other case "the animal looked toward the food 

 when its name was called." Learning in the latter case was 

 considered as attained when the cat responded in this way to 

 its name nineteen times out of twenty, and to "no feed," the 

 counter phrase he used, four times out of twenty. 



Swift (25) reports some experiments upon a dog trained to 

 take meat at a low tone and to refrain from taking it at a high 

 tone. After training, the left tempoial lobe was removed; 

 training was then resumed and w T hen the reactions were re- 

 established, the right temporal lobe was removed. The author 

 reports that even after both lobes have been removed the dog 

 can be retrained (slowly) to distinguish between the two tones 

 used in the original training and also to establish new asso- 

 ciations. 



It is very doubtful if any of the work recently reported by 

 Kalischer and by Swift will bear critical scientific examination. 

 Johnson, in a recent monograph (Behavior Monograph No. 8) 

 discusses their experiments at length. The reader is referred 

 to this place for ciitical evaluation of such studies. 



Johnson (14), in a review of Oscar Pfungst's report, "Der 

 sprechende Hund," accepts Pfungst's explanation of the claims 

 made by the dog's owners. The animal was reported to possess 

 a vocabulary of eight woids: Don, Hunger, Haben, Kuchen, 

 Ruhe, J a, Nein, and Haberland, and with these words to answer 

 accurately certain questions as, " Was hast du?" "Hunger." 



Doctor Pfungst with Professor Vasseler and Doctor Erich 

 Fischer investigated the behavior of the animal, a German
