We are currently recruiting healthy adults between the ages of 20-29 or 50-59 for a multi-day study of the relation between brain chemistry and decision making. The study involves tests of cognitive (thinking) ability, personality tests, and brain imaging.
Only individuals who are currently healthy, are not taking medications that impact attention or mood, do not have a history of using psychostimulants, and are not currently tobacco or nicotine users may participate. Women who are pregnant, lactating, or trying to get pregnant cannot participate.
The entire study takes approximately 24 hours in total, spread out over multiple visits. Participants who complete the study will be compensated for their time.
