Abstract
This experiment investigated the effect of channel load in a 1-, 2-, and 3-meter vigilance task. Also investigated was the effect of training under one of the 3-channel load conditions when subjects were later transferred to a 2-channel condition. Subjects monitored a voltmeter display for 64 minutes. Results showed that the overall performance of the 2- and 3-channel groups was virtually identical, and considerably inferior to the single-channel group in the initial session. A time decrement was exhibited by all 3 groups. In the second session when all subjects monitored 2 channels, no significant differences between groups were found. The results are discussed in terms of time-sharing load on the monitor, and implications for equiptment design and training.Keywords
