The study was designed to investigate the reaction to the emotional stress of pregnant women, by loading MDT (Mirror Drawing Test)-stress and exposing a warning sound to them. Subjects were 53 normal healthy pregnant women (26.8±5.1 years of age) with 26. 5±5.1 weeks of gestation. As the controls were chosen 149 normal healthy non-pregnant women (25.8±7.3 years). The effects of the stress were measured by psychophysiological means such as EEG (Electroencephalogram) and GSR (Galvanic Skin Reflex), as well as CMI (Cornell Medical Index), Complain Fatigue (Physical Level), STAI (State・Trait Anxiety Inventory), other questionnaires, medical records and interviews etc. The results obtained were as follows : (1) No significant difference was observed between pre and post-stimulus loadings in EEG percen tage. (2) However, in GSR counting between pre and post-stimulus loadings, higher count was shown in pregnant women than in non-pregnant women. Especially, the most remarkable was the group of 20-41 weeks of gestation. (3) The repetition of hearing the warning sound did never reduce the stress effect in pregnant group (especially 20-41 weeks). (4) Among the pregnant women, those who have higher STAI-ii value after the stress showed more frequent spontaneous fluctuations in GSR, than did the lower STAI-ii group. Thus, the pregnant women revealed to be highly reactive towards the stress than the nonpregnant women ; they become easily excited, continuing a high level of reaction.
