“…The Virtual Personalities Model drew upon that earlier work to examine in more detail how personality could be understood in terms of the behavior of structured motivational systems. It draws on diverse literatures, summarized elsewhere (e.g., Read, Brown, Wang, & Miller, in press; Read et al, 2010), including those involving the factor structure of personality measures (e.g., Eysenck, 1983, 1994; Lee & Ashton, 2004; McCrae & Costa, 1999; Tellegen, & Waller, 2008; Wiggins & Trapnell, 1996; Zuckerman, 2005), the lexical analysis of trait language (e.g., Digman, 1997; Goldberg, 1981), temperament and neurobiological bases of personality (e.g., Clark & Watson, 2008; Gray, 1987a, 1987b; Gray & McNaughton, 2000; Pickering & Gray, 1999; Rothbart & Bates, 1998; Zuckerman, 2005), an evolutionary analysis of social tasks (e.g., Bugental, 2000; Fiske, 1992; Kenrick & Trost, 1997), taxonomies of human motives (Chulef, Read, & Walsh, 2001; Talevich, Read, Walsh, Iyer, & Chopra, 2017), and our earlier work (e.g., Miller & Read, 1987, 1991; Read, Jones & Miller, 1990; Read & Miller, 1989) on traits as goal-based structures.…”
