註釋A test of aircraft recognition accuracy and decision speed compared the performance of single observers and four-man crews. The test used miniaturized simulations of aircraft which were moved at scaled speeds, altitudes, and distances. The validity of the simulation was evaluated and judged by comparing the results of the miniaturized test with results obtained from a previous full-scale test. Comparison of single observers with crews revealed that approximately 50% of the observers performed more effectively when alone than when with crew, in terms of both accuracy and decision speed. The remaining observers performed either equally well, or more effectively when with a crew than when alone. These two groups of observers were found to prefer different communication sequences. The more effective crew observers tended to be less dependent upon other crewmen judgments than the less effective crew observers. (Author).
