Behavioral
Intervention Name(s)
n-back task
Intervention Description
All participants will be asked to finish the 3-back task and the 1-back task. The 3-back task and the 1-back task will be carried out at intervals to avoid the influence between different tasks. The sequence of the 3-back task and the 1-back task will be counterbalanced across participants.
