[Covariance of the level of activation and work performance as a method of evaluating the work load].


Assuming as proved the claim that there is a relation between the activation level and the results of work performed, which may be presented by means of a curve bearing a reversed "U" shape, it has been assumed that we can think of a work load when there is a negative correlation between these parameters. This assumption has been checked by comparying work… (More)
