Summary
This trial will study how negative emotions affect thinking and decision-making in healthy people to better understand mental disorders.
Who is the study for?
Healthy adults aged 18 to 55 who can understand and sign consent, read and write English. Excluded are those using psychoactive drugs or corticosteroids, pregnant women, NIMH staff/family, people with chronic pain or metal in the body that affects MRI scans, left-handed individuals for certain tests, and anyone with medical conditions affecting the study.
What is being tested?
The trial studies how negative emotions like stress, pain, and craving influence decision-making. Participants undergo emotional stressors (videos, math problems, heat/cold exposure), fill out questionnaires about their state of mind and personality traits while some also perform tasks during an fMRI brain scan.
What are the potential side effects?
There may not be direct side effects from the interventions as they involve non-invasive procedures such as watching videos or solving arithmetic problems. However discomfort from heat application or cold immersion could occur.
