Follow-up to the Introvert Post

My recent post about introversion sparked a lot of comments and discussion, and has lead me down a few paths of exploration. Here are a few of the things I found:

There was a report about “innies and outies” on CBC Television last January, on the Sunday night news show. You can see it here. (It’s about seven or eight minutes long.)

One of the people interviewed in the CBC piece is Professor Brian Little of McGill (and formerly of Carleton University and Harvard). Although I can find no further evidence, this might be the guy I heard on the radio a few years ago; the one who talked about how the brains of introverts and extroverts deal with internal and external stimulation.

Another introvert interviewed in the CBC piece is Marti Olsen Laney, who has written several books about the subject, including The Introvert Advantage and The Hidden Gifts of the Introverted Child. Her newest book, co-written with her extroverted husband Michael Laney, is called The Introvert & Extrovert in Love: Making It Work When Opposites Attract.

Wikipedia has an interesting piece on introversion and extroversion. It includes these definitions, apparently lifted from the Merriam Webster Dictionary: Extraversion is “the act, state, or habit of being predominantly concerned with and obtaining gratification from what is outside the self”. Introversion is “the state of or tendency toward being wholly or predominantly concerned with and interested in one’s own mental life”.

Contrast that with the Jungian view: … introversion and extroversion refer to the direction of psychic energy. If a person’s energy usually flows outwards, he or she is an extrovert, while if this energy normally flows inwards, this person is an introvert.

The article also discusses Eysenck’s theory, which involves brain physiology and function: “…introverts are characterized by higher levels of activity than extroverts and so are chronically more cortically aroused than extroverts”. Because extroverts are less aroused internally, they require more external stimulation than introverts.
