Professor Svyadoshch believes that autosuggestion may be used with success in cosmonaut training. In his opinion, autosuggestion can be of great value to those whose occupation makes particularly great demands on self-control, in particular, Space crews. Svyadoshch reports that it takes five or six months of special exercises to master the autosuggestion technique. This makes a person "immune" to fear, worry, and emotional instability (178). 6. .(U) The Soviets have shown interest in the ability of humans to alter their psychophysiological state by autogenous and exogenous suggestion. A study was conducted to determine the possibility of changing the activity of individual organs and systems of the ‘human body by autogenous and exogenous suggestion. Six test subjects were exposed to 70-day bed rest. Three of the subjects served as controls, and the other three were trained for the first ten days to arbitrarily strain or relax individual muscular groups, with subsequent sleep. Myotonometric data showed that different muscle tonus indices could be reduced 5-25%. ECG, EEG, myotonometric, and actographic data showed that sleep occurred by the 7 to 15th minute during the second to third weeks of the experiment. By the fourth week the test subjects were able to arbitrarily achieve a state of relaxation and sleep at any time, regardless of the emo- tional reaction background. At such times arterial pressure and ; pulse rate were significantly lowered. By the fifth week the * test subjetts attained similar results, although somewhat less effectively, by self-suggestion. Thus it is possible, by auto- genous conditioning, for a subject to attain deep refreshing Sleep at a scheduled time even with a background of different stress factors. Most effective changes in the psychophysical state occurred during direct contact of the test subject with the instructor, but exogenous suggestion was performed almost as well by means of a radio or tape-recorder (179). 7. (U) The possibility of being able to predict suggestibility in man prior to engaging him in long term trials has intrigued the Russians. E.F. Mordinov and A.A. Genkin (180) have shown that the electroencephalogram may serve as one of the abjective quantitative measures of suggestibility in man in the wakeful state. Thirty-nine subjects in quiet wakefulness were subjected to two EEG parameters: (1) average level of asymmetry of oscillations and (2) average period of activity. Significant differences were reported in the average level of asymmetry of 56 UNCLASSIFIED a eeeereneemmnmemeenian NA
