-Payment rules (transportation, lunch, experiment): Concerning the rules of payment of the participants, they must be discussed with Olivier (to pay or not the lunch, to reimburse all types of transport or only the public transport etc...). Once you know how much you are going to pay and on which account to charge it, you have to fill out some administrative paperwork. There are two options 1) You can ask the participant to fill in the document Demande de paiement.Then you bring it back to isabelle (gestionnaire comptable) specifying the account with which you want to pay and she will proceed to the payment via bank transfer. 2) The second preferred option is to complete the document Recu des participants. First, you must go to Isabelle to request an avance caisse, which means that she will transfer money directly into your personal bank account. Once you have the money, you ask the participant to fill out Recu des participants, and you can pay the money directly to the participant yourself (via bank transfert or cash). Then, you also have to bring this document back to Isabelle. If you have extra money from your study, you must of course return it to Isabelle.

 In any case, before launching your study, it is preferable to speak with Isabelle to choose the most suitable payment technique.
