Summary
This early-phase study at UCLA examines whether naltrexone, a drug that blocks opioid receptors, can stop reminders of social support figures from helping people overcome fear. Sixty healthy adults aged 18-35 will undergo a fear conditioning procedure with mild electric shocks, then receive either naltrexone or a placebo before extinction training. The goal is to understand the brain mechanisms behind social support's fear-reducing effects.
