Founded and directed by Dr. Jean Gagnon, the Neuropsychology of Personality Laboratory (NPL) of the University of Montreal is interested in discovering the reciprocal influences involved in personality as well as the cognitive and cerebral processes in relation to the onset of impulsivity spectrum disorders and behaviors.

NPL’s objectives:

  • Identifying the psychological mechanisms and risk factors resulting in the development and maintenance of impulsivity related behaviors and disorders;
  • Develop effective impulsivity spectrum measurement tools adapted to the specific clientele’s needs;
  • The development of effective intervention methods resulting in increased impulsivity self-control and diminishing risk factors.
