The Neuromechanics Lab needs volunteers for a study on effort and movement decision making. You must be English-speaking, right-handed, between 18-40 years old, and have normal or corrected vision, have no movement control problems, and have no recent orthopedic surgeries or broken bones. This study is expected to take 2-2.5 hours. All procedures take place in our campus laboratory (Clare Small Arts and Science building, room 107). Subjects will be compensated.
