Participants needed for decision-making study

Healthy people ages 18-40 are needed to participate in a research study at the JHU medical campus/Kennedy Krieger Institute. The study will use functional magnetic resonance imaging (fMRI) to investigate how various incentives can influence decision-making and performance of skilled tasks. The study lasts about two hours. Participants will perform a series of hand-gripping tasks while we measure the force they exert. We will provide a nominal show-up fee pf $50. Free valet parking is available.

Please note, you are NOT eligible if:

  • You are pregnant
  • You have metal in your body (metal dental work—mouth retainers, tooth fillings, braces, etc.—is fine)
  • You have been diagnosed with a neurological disorder (like tremor/TBI/PD/stroke)
  • You have been diagnosed with a neuropsychiatric disorder (like depression/anxiety)

If you would like to participate in this study, send email to Yixuan Wang at with "Effort-Difficulty Study" in the subject line.

If you would like to contact the PI directly, feel free to write to Vikram Chib at or you can call the lab at 443-923-2716.
