精神分析的鼻祖、奥地利精神病医生及精神分析学家弗洛伊德认为,性和攻击性是人类的两大本能,每个人的一生都在和这两大本能进行抗争,或压抑,或放纵,过分压抑或过分放纵都可能造成心理障碍或反社会行为。青春期的男孩子,其攻击性正处于活跃阶段,如果加以适当的催化和一定的诱因,暴力倾向就会在瞬间转化成暴力行为。 Austrian psychiatrist and psychoanalyst Freud believes that sexuality and aggression are two human instincts. Each person’s life is fighting against these two instincts, suppressing or indulging, Excessive depression or over-indulgence can cause psychological disorders or antisocial behavior. Adolescent boys, whose aggressiveness is at an active stage, will be instantly transformed into violent behavior if properly catalyzed and certain incentives are in place.
