“…Social exclusion can occur in either of these situations: a person can say no to a wedding invitation and can choose to end a decade-long friendship. Research has robustly shown that targets of social exclusion suffer a variety of negative effects (e.g., Leary, 1990 ; Baumeister et al, 2002 ; Williams, 2007a , b ; Slavich et al, 2010 ; DeWall and Bushman, 2011 ; Williams and Nida, 2011 ) but less is known about the sources of rejection (e.g., Poulsen and Kashy, 2012 ; Legate et al, 2013 ; Wesselmann et al, 2013 ; Zadro and Gonsalkorale, 2014 ; however, for a recent discussion of sources of ostracism, specifically, see Gooley et al, 2015 ; Grahe, 2015 ; Legate et al, 2015 ; Nezlek et al, 2015 ; Poulsen and Carmon, 2015 ; Van Tongeren et al, 2015 ; Wesselmann et al, 2015 ; Wirth et al, 2015 ). If one potential goal of research on exclusion is to minimize exclusion’s negative effects, then psychologists need to investigate exclusion from both the target and source’s point of view.…”
