“…Early research focused on the individualistic SVO (maximizing individual payoffs), the competitive SVO (maximizing relative payoffs), and the cooperative SVO (maximizing joint payoffs). Subsequently, the equality-seeking SVO (minimizing the difference between payoffs) and the altruistic SVO (maximizing the co-player's payoff) were added to the theory, and attention focused on a hybrid prosocial SVO combining the cooperative and equality-seeking orientations (e.g., Van Lange 1999; Yamagishi et al, 2013). Approximately 57% of people are predominantly cooperative, 27% predominantly individualistic, and 16% predominantly competitive (Au & Kwong, 2004), and SVO correlates significantly with personality descriptions given by friends and roommates (Bem & Lord, 1979) and predicts everyday activities, including volunteering for charitable causes (McClintock & Allison, 1989;Van Lange, Bekkers, Schuyt, & Van Vugt, 2007 In two-player games, SVO can be formalized as follows (Colman, Körner, Musy, & Tazdaït, 2011).…”
