Summary
This study aims to understand why some people with social anxiety or body dysmorphic disorder respond fully to cognitive behavioral therapy while others do not. Researchers will use brain scans, thinking tests, and questionnaires to look for early signs of non-response. The study involves 160 adults aged 18-45, including both those with these conditions and healthy volunteers.
