82 THE HORSE OF MR. VON OSTEN 



ever he went two places too far to the right or left, and as 

 " error 3 " whenever he went three places too far to 

 either side of the cloth desired, we find the following 

 grouping of errors: 



With Mr. von Osten, a total of 63 errors,; 



73% " error i " 



21 ^ :. . " error 2 " 



4% " error 3 " 



1 % " error 4 " 



I % " error 5 " 



With Mr. Pfungst, a total of 64 errors,; 



68 jS " error i " 



20 ^ " error 2 " 



11^ " error 3 " 



I % " error 4 " 



0% " error 5 ". 



The most frequently recurring error, therefore, was the 

 one in which the horse, instead of going to the cloth 

 desired, approached the one immediately adjacent. On 

 page 79 I said that Hans's errors were without system, 

 but only in so far as it was impossible to explain them on 

 a basis of the colors which seemingly were mistaken one 

 for the other. A part of a series in which Mr. von Osten 

 acted as questioner may serve as an illustration. The 

 order given is that of the experimental series as it 

 occurred. Five colored cloths were used. 



Color of the cloth 

 asked for : blue, brown, brown, brown, brown, brown, green, green. 



I I I I I I I I 



brought: orange, orange, green, green, yellow, green, blue, orange.
