Emotional Development
As children grow, they gradually learn to:
Recognize emotions.
Name their feelings.
Control impulses.
Understand other people's emotions.
Recover from disappointment.
Solve conflicts peacefully.
Development is not perfectly linear. Even older teenagers may struggle
with emotional regulation when stressed, tired, or overwhelmed.
Brain Development
The brain develops unevenly throughout childhood and adolescence.
The emotional and reward systems mature earlier.
The areas responsible for planning, judgment, and self-control continue developing into the mid-20s.
This helps explain why teenagers may make thoughtful decisions in calm situations
yet act impulsively during emotional or peer-influenced moments.
