An auditory discrimination task is used to clarify the relationship between cognitive process and eyelid movement associated with eye closure. The timing of eyelid movement in response to a brief iterative brief sound stimulus is measured. Eyelid movement frequently occurs at a specific time after stimulus onset. This property is similar to that of eye blinking. In addition, an interesting tendency that the eyelid movement occurrence time is lower than that of eye blinking is obtained.
