Effects of the Man on the Task in Complex Man-Machine Systems,
Abstract
This research tested the hypothesis that in a complex man-machine system one of the many influences on the system is the man's constant reorganization of the tasks which constitute the system. The performances of 67 male college students receiving basic flight training were assessed by means of check rides at three different points of training. Factor analyses of each set of check ride data indicated systematic changes occurred in the structure of the task. A three-factor solution appeared in the 10-hour data, two factors were being assessed by the 25-hour point, and only one general factor appeared in the 35-hour data. This finding indicates that future man-machine systems research should no longer be designed under a fixed-task assumption. It is speculated that this assumption may be one cause of the generally found weak prediction of system performance effectiveness over meaningful intervals of time. (Author)
