Outcome Measures

Primary Outcomes (3)

  • The craving of internet gamers

    The craving of internet gamers is measured by a single item Visual Analogue Scale with 1 to 7 likert score.

    0-1 minutes before each set of cue

  • The craving of internet gamers after cue

    The craving of internet gamers is measured by a single item Visual Analogue Scale with 1 to 7 likert score.

    0-1 minutes after showing cue

  • The craving of internet gamers after tasks

    The craving of internet gamers is measured by a single item Visual Analogue Scale with 1 to 7 likert score.

    0-1 minutes after finishing each block of tasks

Study Arms (2)

High Working memory load: n-back task

EXPERIMENTAL

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

Behavioral: n-back task

Low Working memory load: n-back task

EXPERIMENTAL

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

Behavioral: n-back task

Interventions

n-back taskBEHAVIORAL

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.
