Brief Summary
This experiment will explore the joint effects of social information, social support, associative learning, and oxytocin on the development of placebo analgesia. The investigators predict that socially transmitted placebo effects will be enhanced by nasal administration of oxytocin, whereas associative learning effects on pain will not be altered by this pharmacological manipulation

Outcome Measures
Primary Outcomes (3)
Change in pain expectation rating score made on a Visual Analog Scale (VAS) after administration of Oxytocin vs. Placebo
Self reported expectation of pain intensity using the VAS ranging from 0-100 (with 0 representing "no pain at all" and 100 representing "most intense pain imaginable (in the context of the experiment)).
Measured during pain tasks at session 1 (within one month of screening survey completion) and 2 which will be within one week of each other.
Change in pain rating score made on a Visual Analog Scale (VAS) after administration of Oxytocin vs. Placebo
Self reported pain intensity using the VAS ranging from 0-100 (with 0 representing "no pain at all" and 100 representing "most intense pain imaginable (in the context of the experiment)).
Measured during pain tasks at session 1(within one month of screening survey completion) and 2 which will be within one week of each other.
Change in pain unpleasantness rating score during hand holding and control conditions made on a Visual Analog Scale (VAS) after administration of Oxytocin vs. Placebo
Self reported pain unpleasantness using the VAS ranging from 0-100 (with 0 representing "no pain at all" and 100 representing "most intense pain imaginable (in the context of the experiment)).
Measured during pain tasks at session 1 (within one month of screening survey completion)and 2 which will be within one week of each other.
