Can a sugar pill make you happier? scientists study expectation effects on emotions

This study looks at how positive expectations—like thinking you received a helpful treatment—can change how your brain processes emotions. Healthy adults will receive a saline nasal spray labeled as either oxytocin or saline on different days. Researchers will measure mood, brain activity (EEG), and eye movements while participants view emotional faces. The goal is to understand the basic mechanisms behind placebo effects in emotions, which could inform future treatments for depression and anxiety.
