An extravert is a person who comes to know himself through the response of the world around him. Hence the talkativeness (telling a story in order to work out one's own thoughts), the sociability (in order to get feedback) and, quite often, the theatricality (in order to draw other people's attention).
It is all the more paradoxical that the word "extravert" is looked up in search engines half as often as the word "introvert". Either because introverts ask more questions, or because extraverts spend less time in search engines and more time talking to people. Or, quite possibly, because there are more women than men among extraverts (and women are the ones interested in men's questions))). But that claim still has to be checked statistically.
Extraversion is one of the two forms of a person's Attitude. The Attitude is an innate form of a person's relation to the outer world, and it shows itself in the way one thinks, in one's physiology and in one's basic reactions.
The first to write about Attitudes in psychology, as you learned from the article above, was Carl Gustav Jung. But the first poet to go deeply into the differences between Extraverts and Introverts on a large scale was Friedrich Schiller. As early as 1795, in his essay "On the Aesthetic Education of Man", he described the formula of the Extravert like this:
Schiller on extraversion"To bring everything external inward and to give form to everything internal"
You do not become an extravert, you are born one. This attitude develops before birth, and by the time it is formed the "seal has been set". As a rule, extraverts are the fruit of a calm pregnancy: all was well with the mother, and the baby in her belly was calm too. The result is more relaxation and more flow, and less bracing and less need to control themselves and the people around them.
This is easiest to spot on the dance floor. An extravert's movements are unfinished, flowing, melting into one another. Belly dancing and erotic movement are their element. But it is somehow less of a pleasure to watch an extravert dance hip-hop, or any "steps" that call for crisp, finished movements: everything looks more or less right, and yet it is not very convincing.
Introverts and extraverts differ in the spine. Introverts show various forms of curvature of the spine. Many extraverts, for example, have a short neck. Introverts depend more on the structure of the nervous system, extraverts on the structure of the hormonal system.
It is sometimes said that the introvert is oriented more towards the inner world and the extravert towards the outer one, but there is a logical error in that claim. The extravert's basic need is to know himself. Yes, through the world around him, but himself. Every event happening outside is automatically tried against inner reality: "How does this affect me? What has become of me because of it?". And that means the extravert's main attention is focused on his own inner world: having received a fact, he or she thinks about where to fit it in and how to come to terms with it.
