Does anybody know of any research done on neurological/physiological/whatever differences between people who are outgoing and those who are shy and selfconscious?
You mean introverted/extroverted - yeah, plenty…
Is it available on the internet somewhere?
neurologicalillness.suite101.com … troversion
A good lay start. You can probably build from there pretty easily using google.
Look for information about the reticular activating system and introversion. Also, be careful not to confuse the psychological principles of introversion/extrOversion with Hans Eysenck’s theory of introversion/extrAversion as that has to do with criminology.
