THE EFFECTS OF ACCELERATION ON VISUAL BRIGHTNESS DISCRIMINATION

Abstract

Brightness discrimination thresholds were determined at five levels of transverse acceleration and four levels of positive acceleration. Four background luminance levels, ranging from 31 to .03 foot lamberts, were studied. Contrast required to detect an increment in illumination increased with acceleration. This increase was present for both directions of acceleration and for all background levels, but was most marked for positive acceleration, and for the dimmest background. A preliminary study was conducted on the effects of breathing 100% oxygen and 100% oxygen under pressure, on brightness discrimination under acceleration. (Author)
