Evoked heart‐rate and pulse‐volume averages of ten seconds' duration were calculated as responses to verbal stimuli associated with an experimental interrogation. These evoked responses were automatically computed and plotted off‐line, calibrated in standard deviations on one axis and time on the other. Stimulus‐triggered responses were cumulated across individuals for given stimuli, and across diverse stimuli for given individuals. Several distinct individual‐specific forms of evoked response were noted among the intra‐subject averages. In inter‐subject average responses to identical verbal stimuli, several operational stress points of the sentence syntax could be determined. Heart‐rate responses appeared closely time‐locked to the questions presented, while pulse‐volume responses appeared more closely time‐locked to the subjects' own answers.
