Abstract

Workers working in every country usually use words having a meaning of “tiredness” (tukare in Japanese) for expressing their psychological experiences, when they are doing any work activities for long hours or after they finished these activities.
In this paper, the author demonstrated the psychological nature of human tiredness functioning during and after daily life activities of a worker, for the purpose of establishment of a fatigue study method on workers' tiredness.
First, the psychological structure of human daily life activities was argued on the basis of the activity theory that had been put forward by Russian psychologist A. N. Leontief.
According to the argument, human tiredness was psychologically defined as a cognitive phenomenon essentially relating with deterioration of motivation to do daily life activities. It was revealed to have psychological characteristics which are exhibited in operating together with psychological phenomena such as drive, need, emotion, memory and expectancy.
Lastly, the significance of long-term surveys on workers' tiredness for studying their prolonged fatigue was discussed. These surveys can make it possible for surveyed workers to know daily variations in their tiredness during and after their daily life activities including work activities. As a result, the workers may recognize and evaluate their prolonged fatigue conditions definitely.
