精神運動警戒タスク(PVT)、眠気を測定する「ゴールドスタンダード」
Psychomotor vigilance task (PVT), is the "gold standard" of measuring sleepiness. The PVT measures your sustained attention using a short, 2-minute task. You can log your performance over time, and see how your PVT performance changes compared to how much sleep you receive.
