Effects of Backscatter of Brief High Intensity Light on Physiological Responses of Instrument-Rated Pilots and Non-Pilots,
OKLAHOMA UNIV HEALTH SCIENCES CENTER OKLAHOMA CITY
Pagination or Media Count:
Thirty-nine human subjects were exposed to reptitive backscatter light stimulation off a white wall or fog from a Grimes capacitance discharge airplane anticollision light flashing at 1.27 Hertz. Both tonic light stimulus absent and phasic light stimulus present stimulus-bound occipital EEG, heart rate, respiration, skin potentials, and eyeblinks were recorded. The results suggest that, although the flashing anticollision light induces changes in physiological measures which are resistant to habituation, these changes do not extend to the induction of nausea.
