Additional Study Information: The Learning Lab at Columbia University is conducting computer based behavioral studies to address fundamental questions regarding the nature of learning, memory, and decision making. Specifically, we will use behavioral methods to investigate the extent to which learning, memory and decision making may be modulated by factors such as novelty, trial-by-trial feedback, motivation, and time. We're looking for people between the ages of 18 and 35 to take part in a series of simple computer tasks in the lab (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 $17-25 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.
