Player ID

[Seraphina Biell]

If I let play my participants the Public Goods Game, they will receive a player ID. After or before this experiment takes place, I want them to fill in a questionnaire. Will they receive the same player ID or a new one in the questionnaire? For my study it´s very important to associate the answers of the questionnaire with the behaviour in the Public Goods Game. Is there some possibility for that?

Thank you.

Dear Seraphina, yes, if you play them directly after each other, they keep their playerID. In addition, the playerID is stored as a cookie. So if they come back with the same device they also have the same playerID (unless they clean their cookies). Best, Marcus
