Studies which impose no limit upon the number of responses an observer can make usually find high false-positive rates. The present study examines observer performance when limits are imposed. Forty-two bombardier- navigators were divided into three target choice groups 20, 40, and no limit. They examined a moving strip of side-looking radar imagery rear-projected onto a 14 by 14-inch display screen. The displayed image covered a 25-mile wide strip of terrain, simulating a 1320-knot mission lasting 27 minutes.
