Study Arms:
- Gambler performing Go-Nogo (Type: EXPERIMENTAL): In this study, Gambler performing Go-Nogo test. On a computer, various exercises (called Go-Nogo) whose principle is: 2 symbols (for example, a circle and a square) appear in random order on the screen computer. The patient will not press the response button (key on the keyboard) that upon the occurrence of one of the two symbols, in dependence upon the command that it has been given by the psychiatrist, and this as quickly as possible. The patient will successively perform 3 versions of this exercise (with a neutral wallpaper, with neutral/games images or with neutral/games tones). Order of the 3 versions will be determined by randomization.
- Social layer performing Go-Nogo (Type: ACTIVE_COMPARATOR): In this study, social player performing Go-Nogo test. On a computer, various exercises (called Go-Nogo) whose principle is: 2 symbols (for example, a circle and a square) appear in random order on the screen computer. The patient will not press the response button (key on the keyboard) that upon the occurrence of one of the two symbols, in dependence upon the command that it has been given by the psychiatrist, and this as quickly as possible. The patient will successively perform 3 versions of this exercise (with a neutral wallpaper, with neutral/games images or with neutral/games tones). Order of the 3 versions will be determined by randomization.

The patient will successively perform 3 versions of this exercise (with a neutral wallpaper, with neutral/games images or with neutral/games tones).
