How belief changes the pain we feel when we see others hurt
Official title: The Power of Belief: Expectation-driven and Placebo Modulation of Empathic Pain
Run by University of Electronic Science and Technology of China · NCT07367672 · Data updated 2026-11-12
We will test whether telling healthy adults they received oxytocin (or giving real oxytocin) changes how much pain they feel when watching others in pain during brain scans.

Is this trial a fit for you?
✓Likely a good fit
Healthy adults without past or current psychiatric or neurological disorders and not taking psychotropic medications are the intended participants.
✕Probably not a fit
People with psychiatric or neurological histories, those on psychotropic medications, or anyone seeking direct clinical pain treatment are unlikely to benefit from participating.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Healthy adult volunteers are randomly assigned to one of three groups: no-treatment control, a placebo nasal spray described as oxytocin, or a real oxytocin nasal spray. While undergoing functional MRI, participants watch naturalistic videos of people in painful situations and rate the pain they perceive. Behavioral responses will be transformed into analgesia-weighted scores, and neural data will include voxel-wise activity, multivariate predictive patterns, and directed functional connectivity analyses. Group comparisons will test how cognitive belief and oxytocin change subjective empathic pain and the brain network interactions that support it.
Why it matters
Potential benefit: If successful, this work could show ways to reduce empathic distress by using expectations or neuromodulators, informing future approaches to manage excessive empathic pain.
How similar studies have gone: Previous placebo and oxytocin studies in pain and social processing have produced promising but mixed results, so similar approaches have shown some success but are not yet conclusive.
