"The child or adolescent that worries psychologists the most is the one who is asymptomatic, who never questions anything and is obedient to everything." This is the statement made by Sylvie Pérez, a professor of psychology and educational sciences at the UOC. Although there is a tendency to associate a child who gets along well with someone who obeys and vice versa, according to the professor, it is not until the age of 12 that a child correctly associates the concepts of good and bad.
