Abstract
A discrete tracking task was arranged in which movements of a lever extinguished a series of stimulus lights, using either compatible or incompatible display-control relationships. Movement of the lever could be controlled by the subject, or made automatic in order to provide guidance. Six groups of subjects were given nine, one or no guided runs before beginning normal practice on either the direct or reversed form of the task. As expected, the reversed task was more difficult than the direct version. On both forms of the task guidance formed effective pretraining, although nine trials of guidance wore not nine times as effective as one such trial. Guidance tended to have a greater effect upon the reversed form of task, as would be expected were its main function to prevent the commission of errors.
