Difficulties in assigning and identifying emotional states, or to regulate the emotional
costs are recognized as one of the major factors of relapse. This study aimed to evaluate the
emotion regulation processes, in short term (STA, after 1month of withdrawal) and long-term
alcohol abstinent individuals (LTA, at least six months of abstinence), compared to healthy
control participants (C) in a positive and negative emotion induction protocol.
Evaluating the emotional regulation deficits assessed with physiological indicators (heart
rate variability, electrodermal response, pupil diameter) and clinically in presentations of
visual stimuli to emotional value (positive, negative, neutral) in alcohol use disorder's
(AUD) patients with short and long term abstinent compared to a control group of healthy
subjects. The investigators are particularly interested in the evolution of heart rate
variability considered as a good marker of vulnerability to AUD.
Studying the relationships between physiological measures and clinical variables such as
behavioral indicators and self-reported assessment of cognitive and emotional skills among
the three groups (STA, LTA and C).
