However, the definition and measurement of impulsivity is still a matter of debate. The main objective of this paper is to describe a multi-factorial model of impulsivity taking into account its emotional, cognitive and motivational components. Whiteside and Lynam [40] distinguished four facets of impulsivity: Urgency, lack of Premeditation, lack of Perseverance and Sensation Seeking. We will discuss the psychological and brain mechanisms involved in these facets and also propose tasks to assess each one.enType de référence::Rapports::Rapport de recherche
