This chapter explores the differences between introverts and extroverts in terms of their brain chemistry, specifically the role of dopamine. It discusses how extroverts have a stronger response to reward cues, particularly social interaction, due to higher levels of dopamine in their brains. The chapter also touches on the relationship between dopamine, assertiveness, and enthusiasm, as well as the potential implications for introverts who lack dopaminergic activity.
In part two of our look at introversion and extroversion, we dive into the science and psychology of personality.
How do we develop these traits? How much are our genes responsible?
The way brains of introverts and extroverts differ will probably surprise you.
