The purpose of this research study is to investigate how personality traits and neuroendocrine systems relate to decision-making patterns in individuals 18-45 years old. The main question it aims to answer is how neuroendocrine activity impacts decision-making. Participants will complete online behavioral tasks, a stress induction procedure, self-report surveys, and a cognitive assessment. During the session, psychophysiological measures will be collected, including electrocardiogram (ECG) and cardiac impedance (ICG) to monitor heart rate and blood flow, as well as electrodermal activity (EDA), blood drop samples, and saliva collection to assess nervous system activity.
Inclusion Criteria: Borderline Personality Disorder (BPD) group: * Score of 38 or higher on Personality Assessment Inventory-Borderline Scale (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 current study as the criteria used in the other DEPENd lab studies. BPD pa…
Participants will complete the Trier Social Stress Test to induce stress, which includes a public speaking simulation and mental arithmetic.
