12 Effect of Alcohol on Psycho-Physiological Functions. 



EXPERIENCE OF SUBJECT VI. 



Prior to June 29, 1914, the date on which the second series of experi- 

 ments began, Subject VI had served parts of 21 days, a total of approx- 

 imately 70 hours, as a subject for Professor Dodge. The dates for 

 these days, with information concerning the time of day for the partic- 

 ular session, the approximate number of hours' work, the number of 

 experimental periods of repetitions of the series of tests used on the 

 particular day, the doses of alcohol given, together with an indication 

 of the measurements used, are presented in table 1, sections i, n, and 

 in. 1 This table has been compiled solely with the intention of pre- 

 senting a statement showing the experience which the subject had had 

 with these experiments under the general laboratory conditions which 

 obtained. It is not a tabulation of comparable data, for not all of the 

 measurements taken on the several dates and classified under one head 

 are comparable. As an example, normal eye movements according to 

 the table would appear to have been taken on October 22, November 5, 

 November 19, 1913, and January 1, 1914. However, those so^ classi- 

 fied for November 5 and 19 were corrective eye movements during the 

 reading of moving words, and can not be compared with the eye move- 

 ments, right and left, through an arc of 40°, the common measurement 

 used under this name. It was merely a matter of convenience to 

 classify these data for November 5 and 19 in this way, as it represented 

 practice in the eye-movement measurements with the Dodge technique. 

 As outlined in the tentative psychological program, 2 Professor Dodge 

 proposed several measurements, data for which are not presented in the 

 published report of Dodge and Benedict. Some of these measurements 

 were tested, as has been instanced in this case of eye movements, but 

 the amount of data secured with the whole group of subjects was insuffi- 

 cient to warrant its publication. In section n the data which have 

 already been published in Dodge and Benedict's report are indicated 

 by the letter P. The unpublished material represented in section I of 

 the table, December 22 to 24, 1912, was obtained in connection with a 

 series of measurements on the effect of acidosis. These observations 



i There are certain errors concerning subject and date of experiment in the Dodge and Benedict 

 publication. Those which are most likely to confuse the careful reader should be corrected as 

 follows- The 12-hour experiments with Subject VI came on January 1 and 2, 1914, while those for 

 Subject IX came on December 22 and 23, 1913. At places these dates have become confused, 

 giving the false impression that both subjects were used on the same day in these long experiments; 

 page 65, Subject VI, December 22, 1913, should be changed to read January 1 ,1914; ; page 65, 

 Subject VI, December 23, 1913. should be changed to read January 2, 1914; page 66, Subject VI, 

 Con December 23, 1913, should be changed to read January 2, 1914; page 67, Subject IX, 

 January 1, 1914, should be changed to read December 22. 1913; page 68, Subject IX, 

 Con., January 1, 1914, should be changed to read December 22, 191.3; page 68 Subject IX, 

 January 2 1914, should be changed to read December 23, 1913; page 157, Subject IV, February 

 18, should be changed to read February 13; page 158, Subject IV, Con 12-hour experiment, 

 should be changed to read Subject VI, Con., 12-hour experiment; page ,218, Subject VII, the 

 second October 8 should be changed to read October 28 (Dose A) ; page 260, fourth line from top 

 of page, Subject VII should be changed to read Subject IX.
