EFFECTS OF MODIFIED TASK FEEDBACK DURING TRAINING ON PERFORMANCE OF A SIMULATED ATTITUDE CONTROL TASK AFTER THIRTY DAYS

摘要

This study was to determine the effects of modifications in task feed-back during training on performance of a simulated attitude control task after a 30-day interval. The criterion task consisted of compensatory rate tracking in three dimensions by means of "noisy" meter displays and a conventional stick with a twist dimension added. In addition, the intensity of auditory noise present varied proportionately to tracking error in four steps. Equal numbers of subjects trained for 1 or 3 weeks with either noisy or non-noisy displays and under one of two degrees of auditory feed-back specificity (magnitude of steps used to relate visual noise to error score). Subjects trained with visual noise showed better performance after 30 days despite the fact that subjects trained with a noise-free display performed significantly better during training. The subjects trained for 3 weeks showed significantly better tracking performance on 30-day retention test than subjects who received only 1 week of training. The use of more gross steps in auditory noise in training did not significantly affect retention test performance.
