CHANGES OF PERSONAL PSYCHOLOGICAL CHARACTERISTICS IN HEALTHY YOUTHS LIVING AT HIGH ALTITUDE OVER 5000m FOR ONE YEAR AND RETURNING TO PLAIN IN FEW DAYS

To illustrate the effect of personal psychological characteristics on peoples long-living at high altitude,EPQ had been used to test three times on 132 healthy youths of the same group during different time as follows:twelfth day before entering altitude,one year during residing in altitude at 5 070m, 5 200m and 5 380m and tenth day after returning to plain. P marks of ones of long-living at altitude were higher than that before entering (P<0. 01 ). but L was lower(P<0. 05).Among Others the men with moderate emotional stability were decreased and those with emotional unstability as well as those who had tendency of unstability were increased(P<0. 01 in both).Men having moderate personality after returning to plain were more than those before ascending to altitude,and ones with external personality and those who had tendency of external personality were decreased (P<0. 05 in both). In addition, men with moderate emotion stability decreased,with stable emotion and tendency as well as unstable emotion and tendency increased(P<0. 01 in both) while returning to plain. Authors consider that the peoplen personality characteristics in subjects long-living at extreme altitude may be affected.
