Abstract
A simple (one-channel) or a complex (three-channel) vigilance task was administered with or without threat of shock to a large group of flight students. It was found that a larger absolute decrement was obtained in the complex task, but the relative decrements were equivalent for both. One-channel monitoring was better overall than three-channel monitoring in the non-stressed condition. Stressed subjects performed better than nonstressed, and this enhancement was greater for three-channel monitoring.Keywords
