Additional Study Information: The Learning Lab at Columbia University is conducting functional MRI experiments to examine the neural mechanisms that support distinct forms of memory and learning, as well as to explore the relationship between them and between the neural mechanisms of decision-making. Were looking for people between the ages of 18 and 35 to take part in a series of simple computer tasks in the MRI scanner (some of the tasks may involve eye-tracking). The study takes place at the Jerome Greene Science Center (129th and Broadway). Participants will be paid between $20-25 per hour and may have the chance to win additional money. If you're interested in participating, a researcher will contact you to determine your eligibility and to find a time that works with your schedule.
