* Self-assessments based on questionnaires : Strengths and Difficulties Questionnaire - Development and Well-Being Assessment (SDQ-DAWBA) ; Pubertal Development Scale ; Life Events Questionnaire ; Childhood Trauma Questionnaire ; Abbreviated - Diagnostic Instrument for Borderline (Ab-DIB) ; Beck Depression Inventory ; Socio-demographic questionnaire) * and clinical evaluation by a psychiatrist : Mini-International Neuropsychiatric Interview (MINI); Global Assessment of Functioning

The stress elicitation experiment is based on a time-constrained mental arithmetic test in the presence of an observer. The task usually lasts about 30 minutes. During the task, the investigators will monitor: neuro-vegetative parameters (skin conductance, temperature, respiratory and cardiac frequencies, and VNA) ; biological parameters : salivary Cortisol and Amylase before test (baseline), 15 min and 30 min after testing (respectively corresponding to Reactivity and Recovery) ; micro-behavioral cues extracted from 2D video and 3D sensors (Microsoft Kinect).

Structural and Functional Magnetic Resonance Imaging (MRI). The functional acquisition will last 20 minutes and the structural acquisition 18 minutes. All MR image acquisition methodologies are already functioning on the 3 Tesla Prisma machine within the ICM(Brain and Spine Institute), Salpetriere. The fMRI session will provide three types of data: (1) task-related activity to probe the striato-limbic and prefrontal regions, (2) resting state connectivity to examine the integrity of canonical networks, and (3) MR structural images to measure regional volumes of key functional nodes. For the task-related fMRI study, the investigators will use the monetary incentive delay task that reliably elicit an activation in known functional networks underlying reward anticipation/outcome.

Collection of saliva samples of cortisol and amylase repeated three times
