[Effects of a warning signal on heart rate and 17-hydroxycorticosteroid in urine (author's transl)].
The purpose of this study was to test whether a warning signal given prior to an unpleasant stimulus would influence heart rate (HR) and 17-Hydroxycorticosteroid in urine (17-OHCS). The results for HR were as follows: (a) In the anticipation period, subjects given no warning signal (NS group) showed higher degree in their HR than that of those given a warning signal (S group), (b) On at impact, a warning signal tended to decrease subjects' HR when an unpleasant stimulus was given, (c) In the recovery period, subject group indicated lower degree in their HR than that of NS group, and (d) Subject group showed more adaptation by repeated trials to an unpleasant stimulus in their HR. However, as for urinary 17-OHC, nosignificant difference was observed.
