The Tunisian revolution in 2011 helped to free the speech and unleash languages. Thus we witnessed a humorous explosion affecting all areas of life: political, economic, sports, religious and social. The teenagers seem to be the most concerned by this creative expression serving their psychological and social development. In this thesis, we proposed to identify the role of humor in the adolescent process through the study of the functioning of the preconscious, the narcissism, the individuation process and the socialization. What information could it provide about the quality of the adolescent's psychic life and its possible flaws. Would the lack of humor or the reluctance to produce it be evidence of adolescent fragility and an impossibility to manage the drive emergencies enclosing them in a rigid and impenetrable operation? We have therefore drawn inspiration from Rod, A Martin's Humorous Response Questionnary, in order to categorize humor in adolescents aged 13 to 15 years. Then, we explored their psychic dynamics through the TAT projective test. This work allowed us to determine the quality of the preconscious and the psychic characteristics inherent in each group of humor. This study helped to identify a new "non-humor" category that contributes to understanding the phenomenon of religious radicalization in adolescence. Thus the type of humor used by the adolescent, in his cultural context, takes on the value of a psychopathological sign informing about his psychic health.
