General Experimental Conditions. 17 



ulated during this experimental period as they would normally be in 

 the life of any business or professional man, unless he lived under mili- 

 tary training conditions. From the time the subject entered the Lab- 

 oratory until the experimental session for the day was complete, he was 

 continuously under observation. Following the set of experiments a 

 careful physical examination was made. Information obtained from 

 this, together with information obtained from those who knew the sub- 

 ject best, confirmed our belief that he was sincere in his attitude toward 

 the experiments and in his desire to cooperate in them. It is believed 

 that the previous suspicion that the subject might be tampering with 

 the experimental results was not well founded, or at least does not 

 apply to the present series, and that the affidavit made by the subject 

 is to be taken at face value. This affidavit was as follows: 



1. The data given by me concerning the last ingestion of food and the use 

 of alcohol were correct according to the best of my knowledge and belief. 



2. There has been no conscious effort or intention to modify the results of 

 the experiments. 



3. There has been no discussion of the experiments and of probable results 

 with any person outside the Psychological Laboratory. 



4. There has been no habitual use of drugs during the experimental week, 

 no use of alcoholic beverages outside the Laboratory, and no occasional use of 

 any drug that might modify the effect of the alcohol, as far as I know. 



In order that the conditions for the comparison of the results of the 

 two series of experiments may be more fully before the reader, the fol- 

 lowing section of personal history given by Dodge and Benedict 1 is here 

 reprinted.
