Effects of Intranasal Oxytocin and Vasopressin on Social Behavior and Decision Making

The purpose of this study is to investigate the role of a one-time intranasal administration of the oxytocin, vasopressin, or placebo on prosocial decision making such as cooperation and competition in a healthy population of student controls.

Inclusion Criteria:

This includes steroids, medications for psychiatric symptoms like anxiety or depression, stimulants, and medications for high blood pressure. Participants will be asked to tell the investigators of any medications or drugs that they are taking. The investigators will consider the drug interactions with oxytocin and vasopressin prior to study, and participants will not be able to participate in the study if the drug interactions could be dangerous.
