The EEG was characterized by an irregular alpha rhythm, frequently followed by more rapid low- amplitude oscillations, an indication of decreased reactivity of the cortical processes. The condition of the autonomic nervous system was judged from shifts in skin temperature and arterial pressure, both of which were much lower at the end of a work shift than at the beginning. The physiological data were supported by the results of a neurological examination which showed a large number of functional shifts. In general, the adverse effects were most pronounced in those who worked in soft red light. Yellow light was less irritating than green. 2. (U) Further evidence of Soviet interest, especially in red light, is provided by research emanating from Soviet military institutes, The dynamics of work capacity of healthy human subjects during adaptation to colored lights was evaluated from the rate and quality of sensorimotor reactions of varying complexity. The subjects, seated at a specially designed control board, were required to press buttons to switch off the lights at appropriate signals during a two hour adaptation period. Adaptation resulted in changes in the rate and quality of the reactions in relation to the color of the light source and the adaptation time. An increase in wave- length increased reaction speed but impaired quality, while a decrease in wavelength had the opposite effects. Red light produced tension and irritability. Yellow light induced a good mood charac- terized by "increased motor readiness" and sustained attentiveness. Sluggishness and sleepiness were the characteristic reactions to blue light. Green light did not seem to produce any emotional reaction (239). 3. (U) The effect of colored illumination on monkeys has been studied at the Kirov Military Academy. The work reported above also was done at the Kirov Academy. The work as one can see involves not only monkeys but humans. The relationship between agressiveness and color type is of interest especially since the work comes from a known military establishment. An abstract of the work on monkeys follows: "In order to determine the psychophysiological specifi- city and the emotional working capacity as influenced by different colors of the visible spectrum -- so important in technical esthetics in submarines, mines, planes, and light and heavy industries ~- the authors used two rhesus monkeys. Sultan, four years old, was rather immobile and aggressive with a big appetite. Generally he sat at the screen and in the case of a mistaken choice 83 CONTROLLED DISSEMINATION NO DISSEMINATION ABROAD (This oa OE TDENTTAL..
