also a very clear way of telling between an LSE and SLI is this:
1. What do you think of unions?
2. When speaking about topics, what an introvert SLI tends to do is to draw themselves to the center of the event (any) and base the events from the point of view of themselves rather than what the extravert LSE tends to do is which is to describe what's happening.
When I ask and LSE to answer #1, they will say "well, unions can be a good thing for these reasons." Notice there's no "I think" or "I feel" or "I love" when it comes to things of objective nature. This doesn't mean LSE don't say "I love this..." which they do quite frequently. When the same questions are asked of an SLI what tends to happen is that so much subjectivity is emphasized that the objective reasons are lost. What may happen with a response from an SLI is "it doesn't matter to me so why should I worry about it." Well that wasn't the question that was asked was it...on and on.
Let's take what you wrote and analyze it:
You said "In general people tend to think I am an inch or two inches taller than I actually am because of good posture."
I would take this as an objective analysis because it's not saying "I'm good looking, tall, and momma fed me right." (that is SLI
). You said "people tend to think"...this tells me that you probably either assume what they think (an activity) or that is what they are telling you and from that you've reached a conclusion about what's going on with you.
To determine which one you do...because you can seem like either LSE or SLI, you must try to figure out what your typical tendency is...watching someone who has been typed in SLI you may begin to compare your tendencies to that of their own. Do you know any family members who are that type?
