Abstract
The experimental variables in acceleration research should be standardized among all of the different centrifuges. This would make similar data comparable from one laboratory to another. The purpose of this study is to establish an objective and standardized endpoint for positive acceleration experiments. A comparison was made of blackout thresholds to a red filtered light of 760 mu, raised 0.5 log units above visual threshold in dark adapted subjectes and to a white light in the same subjects. A significant difference was found for each subject (p<.02). Differences between white and red light varied from 1.1 to 2.8 g for this group. The differences observed would vary from one centrifuge to another depending on the intensity and transmission spectrum of the white light used. Physiological implications, advantages, and possible sources for error are discussed.
