Borderline Personality Disorder (BPD) involves altered social cognition, notably dysfunctional processing of cues signaling potential social exclusion and heightened social pain. This study uses EEG during a controlled Cyberball task to test whether BPD patients show a functionally altered social-pain network, particularly increased theta activity, when experiencing induced social exclusion.
For patients, a diagnosis of borderline personality disorder (established by a board-certified psychiatrist during a structured interview using the MINI) based on the Diagnostic and Statistical Manual of Mental Disorders (DSM-5)
For healthy individuals, no psychiatric disorders according to the DSM-5 (except for tobacco use)
Must be between 18 and 40 years old
