ABSTRACT

A review of the literature shows that most researchers who attempt to assign personality to computers narrow their focus towards only a small number of personality aspects. Often interactive characters or embodied conversational agents are analyzed with regard to the impact of their introverted-vs. extravertedness. For example, it was investigated as to whether users preferred characteristics that are similar or dissimilar to theirs in terms of introversion vs. extroversion. Nass and Moon (2000) examined the effects of introverted and extroverted signals as presented both textually and visually, and the paralinguistic features of human or computer-generated voices. Other studies have examined those computer systems which present submissive and dominant characteristics, and the preference of users for similar or dissimilar characteristics to their own (Nass et al., 1995). In addition, the impact of introvert or extrovert styles’ assistance during a decision problem has been researched, together with its impact on any trust in the advice (Hess et al., 2009).
