Thirty six volunteer air force personnel were sequentially exposed in a randomized balanced order in a hypobaric chamber to 30 min of baseline (sea level) and mild hypoxia induced by a specified altitude (sea level, 8000 ft and 12,000 ft), followed immediately by breathing 100% oxygen from an oro-nasal mask. Mood and complex cognition were assessed.(More)
The tasks used to assess working memory are a highly contentious issue in cognitive psychology. Previous research has found a weak relationship between two key types of working memory tasks: N-Back and Complex Span. This is commonly interpreted as evidence that one or both tasks possess poor construct validity. However, this finding may be a result of(More)
The decreased pressure in the cabin of a pressurised aircraft (typically equivalent to ~8000 ft) reduces the oxygen level so that the blood oxygen saturation of all occupants falls from >97% (normoxia) at sea-level to below 92% (mild hypoxia). Although exposure to mild hypoxia does not affect well-learned cognitive and motor performance of aircrew, it has(More)
