| Outline of Final Research Achievements |
This study investigated the relationship between cognitive processing and physiological measures of eyeblinks and pupillary responses. It showed that these physiological measures could play an important role in objectively evaluating human cognitive functions. The present results showed a close and reciprocal relationship between the switching of visual awareness (perceptual switching) and the eyeblink. Voluntary blinking or eyelid opening facilitated the perceptual switching, and after the perceptual switching, more spontaneous blinking was observed. In addition, the pupil dilated in response to focusing attention while observers monitored the visual stimulus. How much the pupil dilated depended on the relative length of the monitoring period. The present study suggested the feasibility of a multifaceted evaluation of human cognitive functions by simultaneously measuring eyeblinks and pupillary responses.
