Adolescent rebellion is commonplace, and a lot of research has been done into its causes. Biologically, adolescents have their prefrontal cortex, part of the human brain, put into practice. This results in teenagers’ arguing and testing boundaries. In other words, adolescents make their own decisions and mistakes to develop the prefrontal cortex fully. Besides, hormonal changes may urge them to misbehave or become more impulsive. In view of this, a son’s rebellion may be against his own wishes. On top of that, adolescents want more independence, which is often confused with rebellion. They also want to be in control of their own lives, making their own decisions. The more forceful a parent is, the more counterproductive it is now. Similarly, adolescents seek acceptance and attention. They want to fit in with their friends and want others to take notice of them as well. Meanwhile, parents tend to be too worried and make things even worse, let alone see their teenage children through this hard time.
