Effects of Acute Hypoxia on the Performance of Psychological Tests

Abstract

The effect of 'partial oxygen want' on general mental functioning of pilots flying at high altitudes has been investigated by subjecting flight cadets to different altitude conditions simulated in a decompression chamber. The study is restricted to an assessment of performance as reflected on the G.V.K. intelligence test series. The effects of hypoxia are apparent only at altitudes of 12,500 ft. and above. Oral administration of methylene blue does not seem to enhance tolerance to oxygen want.
