Some findings reveal extroverts as more adept at reading nonverbal cues, and attribute this to the extrovert's greater interest and experience with social interactions. Another line of research using subliminal images of facial emotion found introverts to be more sensitive to the differences, and hypothesized that this may be why introverts regulate the amount of incoming social information.

If the extrovert is trying to "cheer up" the introvert - extroverts are programmed to seek social rewards! - he or she may feel like a failure if the introvert remains unmoved.

When an introvert is quiet, don't assume he is depressed, snobbish or socially deficient.

With public speaking, practicing congruence is very helpful - allowing the words to be expressed with the face and body. It helps to think of simply "turning up the nonverbal volume."

An extrovert is more likely to share immediate reactions and process information through conversation.

If you ask an introvert a question, wait until she thinks about it. Introverts think before speaking, not through speaking. If you want to get to the good stuff, you need to slow down.

Introvert, her brain responds with a high level of activity, it is as if several lights start flashing on a control panel.
