Comparison of the vigilance performance of men and women using a simulated radar task.
The present study examined the question of possible sex differences in the ability to sustain attention to a complex monitoring task requiring only a detection response to critical stimulus changes. The visual display was designed to approximate a futuristic, highly automated air traffic control radar display containing computer-generated alphanumeric symbols. There were 26 men and 26 women tested, each over a 2-h session. Sixteen targets appeared on the screen at all times, with 10 signals (a designated change in the alphanumerics) randomly presented during each 0.5 h of the test session. Detection latency to the signals increased significantly during the session, but there was no evidence of any significant differences between the sexes in the magnitude or pattern of this increase. The results are discussed in terms of a general decline in alertness that was apparently equal for both sexes.
