Interventions/Control_1
In this study, participants inhale air with an oxygen concentration of approximately 30% using an oxygen concentrator via a headset while performing a learning task.
The duration of oxygen inhalation is up to 2 hours per day.
The learning task is conducted for up to approximately 9 hours per day (including breaks), during which both oxygen and ambient air conditions are applied to the same participants.
The learning task consists of an English vocabulary program (1800 words), performed according to the participant's learning progress.
The intervention is conducted over 3 days.
Interventions/Control_2
Under ambient air conditions, participants perform the learning task without using a headset and without oxygen supply.
The learning task is conducted for up to approximately 9 hours per day (including breaks), and participants engage in an English vocabulary learning program according to their learning progress.
This intervention is conducted over 3 days.
