Primary |
Changes in Cortisol (CRT) during Trier Social Stress Test (TSST) |
The study drug will be administered 40 minutes before the TSST. Serum cortisol and Adrenocorticotropic hormone will be measured via peripheral IV 30 minutes before the TSST (-30), at the start of the TSST (0 minutes), and at minutes 10 (during the speech task), 15 (during the math task), 28 and 38 (during recovery). |
-40 minutes, -20 minutes, 0 minutes, +10 minutes, +15 minutes, +28 minutes, +38 minutes, +48 minutes |

Secondary |
Changes in Adrenocorticotropic hormone (ACTH ) during TSST |
The study drug will be administered 40 minutes before the TSST. Serum cortisol and Adrenocorticotropic hormone will be measured via peripheral IV 30 minutes before the TSST (-30), at the start of the TSST (0 minutes), and at minutes 10 (during the speech task), 15 (during the math task), 28 and 38 (during recovery). |

|
Secondary |
Changes in the lagged association between ACTH and CRT during the TSST |
Correlations will be quantified between ACTH at time j and CRT at time j+1 to test the extent to which CRT response is blunted by exogenous OT. |
ACTH at -40 minutes, -20 minutes, 0 minutes, +10 minutes, +15 minutes, +28 minutes, +38 minutes and Cortisol at -20 minutes, 0 minutes, +10 minutes, +15 minutes, +28 minutes, +38 minutes, +48 minutes |

Secondary |
Changes in high frequency heart rate variability, an index of parasympathetic activity, during the TSST |
Recording of autonomic activity beginning prior to study drug administration (-40 minutes) until the end of recovery from the TSST (+38 minutes). Mobile Impedance Cardiographs (MindWare Tech Ltd, Gahanna, OH) will be used to measure cardiac rate and interbeat interval (IBI). MindWare Heart Rate Variability (HRV) software will be used to derive respiration and to calculate high frequency HRV and respiratory sinus arrhythmia from the IBI series as indices of parasympathetic activity. |

Recording of autonomic activity beginning prior to study drug administration (-40 minutes) until the end of recovery from the TSST (+38 minutes). Mobile Impedance Cardiographs (MindWare Tech Ltd, Gahanna, OH) will be used to measure pre-ejection period (PEP). PEP will index sympathetic activation. |
