Introverted children enjoy the internal world of thoughts, feelings and fantasies, and there’s a physiological reason for this. Researchers using brain scans have found introverts have more brain activity in general, and specifically in the frontal lobes. When these areas are activated, introverts are energized by retrieving long-term memories, problem solving, introspection, complex thinking and planning.
Extroverts enjoy the external world of things, people and activities. They have more activity in brain areas involved in processing the sensory information we’re bombarded with daily. Because extroverts have less internally generated brain activity, they search for more external stimuli to energize them.
I’m sorta mystified why the article paints introverts as this strange Other. I’d consider myself an introvert, and I think I socialized and developed pretty well. Heck, I’m not only an introvert but I was homeschooled. If anybody should have ended up screwy it should have been me. Last time I checked, I was pretty cool.
