Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

High Working memory load: n-back task

During the intervention, each participant of this group will finish the 3-back task.

Group Type EXPERIMENTAL

n-back task

Intervention Type BEHAVIORAL

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.

Low Working memory load: n-back task

During the intervention, each participant of this group will finish the 1-back task.

Group Type EXPERIMENTAL
