I am concerned about learning through observation. If children see parents arguing frequently, sometimes intensively, will these children, in the future, engage in bullying others in school or even be a contentious partner in adulthood?
This depends on what the child, who now is an adolescent or an adult, has learned from what was observed about the parents. It is possible that the person might gain wisdom from the parents’ fighting and realize that such a pattern is not healthy. Thus, the person may deliberately commit to not following the parents’ behavior. In contrast, if the person does not reflect on the potentially destructive pattern, then, yes, the person may grow up to show bullying behaviors in school and to repeat the pattern of a conflictual relationship with a partner. In other words, insight along with a commitment to not imitate the conflictual behavior might spare the person from repeating the parents’ behavioral pattern.
