入选标准
- •healthy controls
排除标准
- •Past or present psychiatric, neurological, endocrinological or severe chronic medical illness.
- •Use of medications or drugs that would interfere with study results. 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.
- •history of drug or alcohol addiction
- •Pregnancy or Nursing Status: Because of the risk to an unborn fetus or infant, women who are pregnant or nursing are excluded from this protocol. All females will have a pregnancy test performed no more than 24 hours before each drug administration and will not be able to participate if the pregnancy test is positive.
研究组 & 干预措施
Intranasal Oxytocin
Participants will self-administer 24 IU Oxytocin. 5 puffs per nostril (1 puff = 2.5 IU Oxytocin).
干预措施: Intranasal Oxytocin (Drug)
Intranasal vasopressin
Participants will self-administer 20 IU vasopressin. 5 puffs per nostril (1 puff = 2 IU vasopressin).
干预措施: Intranasal vasopressin (Drug)
Intranasal placebo
contains all the ingredients as in the oxytocin and vasopressin conditions, save for the active ingredient. Participants will self-administer 5 puffs per nostril.
干预措施: Intranasal placebo (Drug)

时间窗: approximately 45 minutes after intranasal administration of vasopressin, oxytocin, or placebo
A group analysis will compare compensations preference (competitive vs. noncompetitive), performance and outcomes and monetary allocations on several economic games between the oxytocin, vasopressin and placebo groups.
次要结局
