Official title
The Effects of Cortisol and Norepinephrine Modulation on Emotional and Nonemotional Processing
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to examine how hormonal changes that occur during stressful situations affect thought and emotions. Results from this study may lead to treatments that can alleviate the psychological effects of trauma. Levels of cortisol and norepinephrine increase in response to stress; these hormones also influence thought processes. This study will give hydrocortisone and/or yohimbine (a stimulator of central norepinephrine) to healthy adults in order to model the stress response and to better understand the way people process information during traumatic events. This study comprises two experiments in which the stress response is pharmacologically modeled. Participants in the study will have two study visits. During Visit 1, participants will undergo a psychiatric assessment, complete neuropsychological tasks, and have their IQ measured. During Visit 2, participants will be given hydrocortisone and/or yohimbine. Blood will be collected before and during this. Participants will then perform two experiments. In one experiment, participants will hear a story with emotional and non-emotional segments; in a second experiment, participants will view both emotional and non-emotional stimuli.
