When a child turned 14 years old, his father often said he wished he was his "normal" self as he was much less temperamental. He was able to control his emotions. How might a psychologist explain these emotional outbursts to the father? 

• His son's egocentrism is not fully able to be regulated by the dopamine levels.
• The gaps between his neurons are growing too rapidly, and therefore, the synaptic connections are firing too quickly.
• His son's amygdala is developing earlier than his prefrontal cortex, and therefore, he cannot logically process the emotions.
• His son's identity is being challenged and the confusion is causing frustration and anger.
