Additional Study Information: Our lab is conducting a series of research studies investigating people's memory and decision-making. As a healthy study participant, you will be asked to complete a set of self-report questionnaires probing demographics and personality traits, followed by a number of computer-based tasks. Study participants earn between $15/hour for their time. The study may involve potential performance bonuses. The study is typically expected to take 1-4 hours in total. All the experiments are non-invasive and have been approved by the Columbia IRB. The study will be conducted at the Columbia University, Zuckerman Mind Brain Behavior Institute (129th and Broadway).
