MOL: Predicting Four-hour Levels of Psychomotor Performance from the Initial Half Hour

Résumé du livre

Four subjects participated in an MOL-like nutrition study using freeze-dehydrated, bite-sized 'Apollo' food. The two experimental subjects were confined in a small (300 cu. ft.) altitude chamber operated at 27,000 feet with an atmosphere of 70% oxygen and 30% helium. Psychomotor testing was conducted in 4-hour sessions three times a day, every other day, alternating with two control subjects. No major psychomotor changes were observed, except on the short-term memory task, which appeared to reflect motivational factors. Correlations between the first half hour and the remainder of the testing session ranged from -.21 to +.96 and were scattered across that range. It was concluded that a daily half-hour psychomotor test of space crews is probably not sufficiently stable to meet biomedical monitoring requirements. (Author).
