The concept of the pseudo-quickened display is introduced as a technique for aiding the control of higher order systems. In this display the intensity of the cursor is employed as a cue for optimal switching of manual control input. Performance on this display is compared with performance on an unaided, a quickened, and a phase plane display. Some advantages over the conventional display in performance are demonstrated by all three aided displays. When all aided groups transferred to an unaided conventional display, only those trained with the pseudo-quickened display showed benefits of prior training. This group also performed better than those who trained only with the conventional display.
