Explanation:

Adolescence is a transition phase from childhood to adulthood.  The views and opinions of an adolescent per time is therefore a tool in studying level of  emotional maturation. A child usually has emotions and perceptions influenced by parents, environment and decisions made by guardians or older friends. This implies that a child is not personally responsible for the control of his/her opinions or perception of events or emotions.

When maturation is beginning to occur in an adolescent, the adolescent takes a more personal responsibility for thought, perception and views of events/emotions experienced and can communicate more personalized views. The adolescent is also able to put restraint on reactions to certain emotions as maturation occurs.
