Abstract
The sense of busyness often reported by workers who are requested to keep high level of safety. Therefore, it is important to clarify a meaning of the sense of busyness. The present paper describes an experimental study on the relationship between “the sense of busyness” and MWL (Mental Workload) resulting from some simple desk work as a task. In Experiment, the relationship between the sense of busyness and MWL was investigated under 4 busyness conditions suggested by previous studies. As a result, a high positive correlation between sense of busyness and MWL was found, suggesting that sense of busyness may be affected by some other sub-factors included in MWL different from time pressure. For instance, it was found that feeling of “frustration” may be one of them. The finding of this study may contribute to the understanding and reduction of human errors.
