Study summary

The purpose of this study is to evaluate the impact of methylphenidate, a mixed dopaminergic and noradrenergic agent, onto the different components of motivation: decision-making, effort allocation and instrumental learning.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • weight>= 50kg and \<=90kg
  • free and
  • social security affiliation
  • no chronic illness
  • no previous participation to a protocol wth similar tasks
  • no special legal status (guardianship,trusteeship)
  • no personnal or familial neurologic or psychiatric background
  • no device for a reproductive woman

Exclusion criteria

Exclusion Criteria:

  • inability to squeeze a handgrip
  • smoking
  • psychoactive substance consumption less than 3 weeks ago
  • pregnant or breastfeeding woman
  • to methylphenidate
  • hyperthyroidism
  • cardiovascular or cerebrovascular disease
  • respiratory, hepatic or renal failure
  • glaucoma
  • pheochromocytoma
  • gluten intolerance or hypersensitivity
  • galactosemia, glucose malabsorption syndrome, lactase deficit
  • countraindicated meds (IMAO, IMAO-A, orhtosympathomimetics, alcaloids, linezolin, enzymatic inducers, psycho-active drugs)
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Interventions

What researchers measure

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).

    Time frame: two hours after administration

Secondary outcomes

  1. coefficient of sensitivity to effort

    Parameter characterizing the influence of effort 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).

    Time frame: two hours after administration

  2. coefficient of sensitivity to punishment

    Parameter characterizing the influence of punishment 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).

    Time frame: two hours after administration

  3. coefficient of sensitivity to delay

    Parameter characterizing the influence of delay expectation 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).

    Time frame: two hours after administration

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 24, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
