Role Of Sensitivity to neuroEndocrine Systems in Social Decisions (ROSES)

Inclusion Criteria: Borderline Personality Disorder (BPD) group: Score of 38 or higher on PAI-BOR Participants in the BPD group will be primarily recruited from the two DEPENd lab studies that maintain large samples of BPD participants. To ensure maximal similarity between BPD participants recruited from other DEPENd lab studies and BPD participants recruited through other recruitment sources, the investigators will use the same criteria for the BPD group in the ROSES study as the criteria used in the other DEPENd lab studies. BPD participants in the two DEPENd lab studies from which the investigators will be recruiting must meet the following criteria: 3+ BPD symptoms, one of which must be affective instability, per clinical interview Participants must score at least 80 on the Reynolds Intellectual Screening Test (RIST).
