A STUDY OF THE BEHAVIOR OF THE PIG

problems, the data refer only to first choices in each trial, the 

 column headed R containing the number of correct first choices 

 and that headed W the number of incorrect first choices for 

 each series of trials or for the day. It further appears from this 

 table that five trials constituted the regular series in problem 1, 

 and it should here be stated that the experimenter always re- 

 sumed experimentation at the point in the regular series of 

 settings at which work had been interrupted. He therefore pro- 

 ceeded in regular order from setting 1 to setting 10 and then 

 returned to setting 1 and repeated the trials. 



Further comment on the behavior of the animals in problem 

 1 is needless, for the task is but slightly more difficult than the 

 acquisition of a simple position habit, and it has already been 

 satisfactorily demonstrated that many of the vertebrates acquire 

 such habits with ease.
