Individual differences in adaptational capacity during sustained hypergravity (2003)
The purpose of this research is to develop and validate a quantitative method for examining the environmental effects of long duration space flight on individual crewpersons ability to adapt to microgravity. Previous studies have shown that the use of multiple converging indicators (electrophysiological measurements, behavioral responses, and self-reports of symptoms) is a more reliable method for assessing environmental effects on performance than any one indicator alone. This methodology was applied in a laboratory study, which examined the effects of an anti-motion sickness medication, promethazine, on cognitive, perceptual, and neuro-motor performance [1]. The results suggest that effective doses of this medication that are currently used to counteract motion sickness in space may significantly impair the operational performance of astronauts.
