抄録

The techniques for the measurement and assessment of mental workload (MWL) are divided into three categories: (1) subjective measures, (2) performance or task measures, and (3) physiological or biochemical measures. Therefore, MWL should be measured and assessed from multi-parameters in the above categories. The authors have already proposed an experimental protocol for assessing MWL in the sense of mental strain. The experimental protocol consists of 3-min resting periods, graded step-wise and base-grade mental arithmetic pace periods.<br>To evaluate the usefulness of the experimental protocol, the relation between pace level of mental arithmetic and subjective workload evaluation (self-rating score on 0-10 graphical board), and performance evaluated with the percent of correct answer at each period were examined in 15 healthy male volunteers (19-25yr).<br>Respiratory rate (Rr) and tidal volume (VT) were measured throughout all periods. Power-spectra of low, i. e. 0.04-0.15Hz (LFP), and high frequency band, i. e. 0.15-0.5Hz (HFP), at each period were calculated from continuously recorded R-R interval (RRI). Baroreceptor reflex sensitivity (BRS) at each period was estimated using the sequence scanning method proposed by Bertinieri et al. from beat-by-beat measurement of RRI and systolic blood pressure (SBP) under vascular unloading condition.<br>It was confirmed that the pace levels of the mental arithmetic at each period in the experiment could be utilized as the useful indices of MWL in the sense of mental strain, judging from both subjective workload evaluation and performance.<br>In addition to the Rr, LFP and HFP derived from spectral analysis of RRIs, it was clarified that BRS, less affected by breathing than the HFP, could be one suitable parameter for the measurement and assessment of MWL in the sense of mental strain.
