| Emotion Bias Modification Training | Other | The training aims at associating gaming pictures with negative words and pictures of healthy activities with positive words. Gaming pictures are always presented with a pair of negative words. Pictures of healthy activities are always presented with a pair of positive words. Each picture is presented with a fixed pair of words. Participants will be instructed to select one word to get the most monetary reward. Specifically, selecting a fixed word of the word-pair will be associated with a high probability (eighty percent) of getting a monetary reward and a low probability (twenty percent) of no reward, and probabilities will be reversed for the other word. Each training run will comprise 100 gaming picture trials and 100 healthy-activity picture trials, presented in a pseudo-randomized order. Participants will receive two training runs every day. The whole training includes 14 days. |
