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