| Research Abstract |
Eye-movements, blinking and pupil size respond to visual or audio stimulus to require information processing. It is well known pupil size increase with task difficulty. We investigated whether their changes are correlated and can be indices of mental activity. First experiment, audio instruction was presented while gazing and following a marked point which moved periodically in the central point and a point on concentric circle. Audio instructions asked to recall memorized word, cap verses or oral calculation. Second experiment, subjects took part in driving simulation game with same audio tasks. Pupil size, blinking and eye-movements were observed in both experiments.
In the first experiment, the averaged pupil sizes and blinking rate significantly increased with visual angle of gazing and following task, and audio instructions. The gazing time and saccadic responses for the target decreased in response to audio instructions. In the second experiment, pupil sizes and blinking also significantly increased in response to audio instructions. The gazing time and saccadic responses also significantly decreased in response to audio instructions.
From these results, it suggested eye movement model for evaluating mental activity, which was based on correlations between blinking time and gazing time, and between blinking time and saccade occurrence time. For verifying this model, the correlations among them were examined under some eye movement conditions. This verification provided the evidence that pupil, blinking and eye-movement responses can be indices of mental activity.
