In order to estimate the mental workload, electroencephalogram (EEG) was measured during the Figure Stroop Task performance from ten healthy adult voluntary participants. In the experiment, two kind of visual stimuli were prepared: congruent and incongruent stimuli (figure and number of the figure was congruent or incongruent). Participants were asked to answer the number of displayed figures by pressing designated key. In the task, two different instructions to the participants were used: (1) respond as soon as possible, and (2) respond accurately. Integrated theta component of the EEG were compared between under condition of (1) and that of (2). Relative power percentage of theta component in condition (2) was larger than that in (1). The result suggests that the theta component was related with subjective difficulty of the task.
