Direct linkHuber, Susanne; Krist, Horst – Journal of Experimental Psychology: Human Perception and Performance, 2004
Performance in 2 versions of a computer-animated task was compared. Participants either indicated the time of arrival of a target that rolled off a horizontal surface and fell--hidden from view--onto a landing point (production task) or judged flight time on a rating scale (judgment task). As predicted, performance was significantly better in the…
