The facial temperature alters in such cases as when a human plays exercises, when the ambient temperature changes, or when he feels psychological shock. I attempted to estimate the facial temperature change which was caused by psychological change in the human mind.In room temperature (between 22 and 26°C) facial temperature and heart rate of male students stretching a back muscle dynamometer and playing role in the psychodrama were measured by an infra-red camera. Subjects stretched the dynamometer as quickly and powerfully as possible, and held it for 10 seconds. And a trial was repeated five times every two minutes in an exercise. Facial temperature and heart rate of subjects increased while stretching the dynamometer. The facial temperature of most of the subjects decreased as the trial was repeated and the heart rate of subjects recovered soon after the exercise. But, in 3 of 10 subjects, the facial temperature increased gradually even after the stretching as the trial was repeated and their heart rate also increased. On the other hand, in the psychodrama, increased facial temperature of subjects who experienced psychological shock was kept high for more than 20 minutes. Then heart rate of subjects was not changed.I developed a system which estimated the human psychological change by calculating deviation from the mean in measured data.
