PROGRAM OF RESEARCH. 59 



Psycho-physiological measurements. — An extended series of psycho- 

 physiological measurements was made by approved methods in both 

 group and individual tests whenever the subjects visited Boston. 

 Full details are given of the various tests in later sections. 



WEEK-END PROGRAM. 



To illustrate the personal demands made upon the subjects as a 

 result of these observations, a typical week-end program for Squad A 

 is given. Beginning early Friday morning at Springfield, the activ- 

 ities of the squad are shown until the conclusion of the tests on Sunday 

 in Boston. 



Friday: 



5^30" a. m. Nine men ready for respiration experiments; 7 men portable 

 respiration apparatus; 2 men respiratory-valve apparatus. Routine 

 of experiments: Bladder emptied; weighed (stripped); lay on 

 couch for preliminary period; mouth temperature taken; two 

 periods (10 to 15 minutes each) on respiration apparatus; pulse and 

 respiration rates taken during experiment; alveolar air determina- 

 tions made for 2 men on respiratory-valve apparatus. 



6M5" a. m. Breakfast; pedometer readings recorded. 



Q'^SO" to ll'^SO™ a. m. Bicycle ergometer experiments with Professor John- 

 son; 5-minute periods; subjects, Bro, Gul, Gar. 



12''10" p. m. Dinner; pulse-rate counted at wrist by subject (sitting). 



11^30™ to 4''30'" p. m. Bicycle ergometer experiments with Professor John- 

 son; subjects, Pec, Vea, Can, May, Spe, Mon, Tom, Kan, Pea. 



6 p. m. Supper; pulse-rate counted at wrist by subject (sitting). 



Saturday: 

 5''30" a. m. Nine men ready for respiration experiments; regular routine 



followed. 

 7'^30" a, m. Breakfast. 

 9''10°' a. m. Train Springfield to Boston. 

 11^36°' a. m. Squad arrived in Boston.

 research (page 149). Pulse-rates (sitting) during psychological 

 tests; skin temperature measurements at end of psychological tests. 



7 to 10''30°^ p. m. Individual psychological measurements in psychological 



laboratory (60 to 70 minute period) ; measurements given to 4 men 



simultaneously. When not occupied with psychological tests, the 



men were given the following: Clinical examination by Dr. Goodall; 



blood tests by Miss Gibson; Du Bois body-surface measurements; 



profile photographs; 5-minute practice in walking on treadmill. 

 10^00™ to 10^30°' p. m. Men went to bed in the group respiration chamber 



as soon as all had finished the tests previously mentioned. 

 10h45m p, m. Men all in bed, cover of group chamber closed; preliminary 



period of experiment began. 

 11^15™ p. m. Respiration experiment proper began; periods approximately
