Title and Subtitle: Effects of backscatter of brief high-intensity light on physiological responses of instrument-rated pilots and non-pilots
Report Date: March 1972
Authors: Zeiner AR, Brecher GA
Abstract: 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.
