Outcome Measures

Primary Outcomes (1)

  • coefficient of sensitivity to reward

    Parameter characterizing the influence of reward expectation/experience onto behavior for each individual. This parameter is estimated through the fit of computational models to behaviors recorded in a battery of motivational tasks (choice task, effort task, Learning task).

    two hours after administration

Secondary Outcomes (3)

  • coefficient of sensitivity to effort

    two hours after administration

  • coefficient of sensitivity to punishment

    two hours after administration

  • coefficient of sensitivity to delay

    two hours after administration
