Kristi Scott has published her essay The Second Self through Second Life: Mask or Mirror? as part of the book The Real and the Virtual.
As members of a society, there is a variable and determinable array of both personality types and the combinations in which they fit together. In this particular exploration, there is a focus on the continuum between those who are self reported introverts and those who are self reported extraverts. This paper seeks to explore and lay out the real world distinctions of introverted and extraverted individuals based on published research; then to look into and examine virtual life distinctions of introversion and extraversion in SecondLife® to look for any correlations or significance.
