What is thus indicated bythe average differences will likewise be found to be true for the indi-vidual periods 2, 3, 4, 5, and 6 for the pulse taken under the differentconditions from 1 to 7; that is, the differences for normal days haveusually the plus sign, while those for alcohol days are usually minus.

Flo. 15.—Average duration of pulse cycle under experimental conditions 1 to 7 on normal andalcohol days, as compared with pulse duration during word reactions (5 and 6). The effect of alcohol is found by deducting the normal differencefrom the alcohol difference. These results are given for each of theseven experimental conditions in table 20, and are also stated in termsof per cent. They are likewise summarized in table 21, which shows byperiods the average effect of alcohol for each of the conditions. Thereare only two values in the latter table which are preceded by the plus 116 Effect of Alcohol on Psycho-Physiological Functions. sign, i. e., + and + It is clear from table 21 that the pulse wasquickened most under the experimental conditions 2, 3, and 4, that is,in rest after the patellar reflex, in rest after the faradic-thresholdmeasurement, and with the subject holding the voice key before theword-reaction test.
