[Parameters of acral vasomotor activity--sensory arousal variables in psychological stress]

By means of complex methods in 65 test persons from a large number of parameters the photopulse amplitude and the rheographic quotient at the finger apart from the heart rate and the blood pressure were established as very sensitive demand variables under psychic stress. The temporary and formal criteria of the volume pulse curves are less well suitable for this purpose. In the different reaction patterns the inclusion of sensitive biosignals of the acral vasomotricity is an information gain for the demand diagnostics under psychic stress.
