Primary Outcome Measures :
  1. Prosocial behavior [ Time Frame: Baseline ]
    The prosocial behavior will be assessed by conventional economic games, including dictator game, message game, and ultimatum game.

  2. Cognitive flexibility [ Time Frame: Baseline ]
    Cognitive flexibility will be assessed by psychological cognitive paradigm, i.e. reversal learning paradigm. The participants will be asked to choose the item with high probability to win reward.

  3. Valuation of social information [ Time Frame: Baseline ]
    The valuation of social information was measured by psychological paradigm, developed from animal studies, called "pay-per-view". The participants will be asked make decision about more social information or more monetary reward.

  4. Optimism bias [ Time Frame: Baseline ]
    Participants will complete two sessions of life event estimation, i.e. estimating their likelihood of experiencing each event on a self-paced basis.

  5. Emotion recognition [ Time Frame: Baseline ]
    After viewing a video, participants will be asked to judge the person's attitude in the video. Through this paradigm, investigators could test emotional bias in social interaction in depressive patients.

  6. Model-free & model-based tendency [ Time Frame: Baseline ]
    Participants will be asked to complete a two-stage task, by choosing the stimuli with high probability to obtain reward.
