Abstract : The experiment assessed the extent to which operators employed predictive behavior on two-dimensional tracking. Two problems were presented: in one, operators were asked to extrapolate an overlearned trajectory upon the disappearance of the target and in the other, operators tracked one of four possible trajectories with and without pre-test knowledge concerning the specific trajectory that would be presented. No evidence was found which suggested that operators exhibited predictive behavior on the bases of trajectory experience, immediate past history of the target, or expectancies derived from the pre-test trajectory information. The results also indicated that tracking error is largely a function of trajectory pattern, rather than the actual target dynamics (velocity, acceleration), and that error magnification facilitated performance on all patterns.
