研究概览
简要总结
The purpose of the study is to learn how differences in learning under mildly-stressful circumstances may be changed by taking oxytocin. Oxytocin is a hormone made naturally in the body. The investigators will also examine the impact of any anxiety, depression, and stress related symptoms on learning processes.

结局指标
主要结局
Differential Skin Conductance Response (SCR) During the First Two Extinction Trials
时间窗: Day 2 of Conditioning (1 day post Day 1 of Conditioning)
Differences in skin conductance response (SCR) between the active vs. placebo conditions trials will be used to assess for the impact of oxytocin on fear acquisition and extinction. We will take a mean of the first two extinction trials to get this measure. Data was gathered in micro-Siemens and then underwent a square root transformation.
