Abstract:

Three groups of 15 subjects each were exposed to 3 different combinations of intermediate staging altitudes and exposure times, and were then tested for visual target detection capability at a final altitude of 4300 meters. All groups with s-aging exposure performed better at altitude and had fewer symptoms of acute mountain sickness than a fourth group which went directly 4300 meters altitude from sea level. The data showed that task factors both viewing distance and degree of peripheral target placement significantly influenced detection time within all groups regardless of altitude exposure variations. Field-dependence-independence Hidden Shapes Test and extraversion- introversion Maudsley Personality Inventory were found to be separately and jointly related to accuracy of target detection. The major effects were attributable to the notably poorer performance of Ss characterized as field- dependent extraverts.
