It is well known that pupil diameter changes with psychological state or with luminance of visual stimulus. In this research, we manipulated the psychological state of the observers using auditory stimuli under various luminance conditions of the stimulus and measured the diameter of pupil to investigate the interaction of the effects of psychological state and of brightness on pupil diameter. In one trial, the psychological state was changed by the change of the task load and the stimulus luminance was sinusoidally changed. In the result, the interaction between the effects on the pupil diameter of psychological state and of the luminance was clearly observed. The amplitude and mean of the change in pupil diameter produced by luminance increased as the task load increased. This result would contribute to develop a system estimating psychological stat using the date of pupil diameter.
