“…For example, the Unmitigated Approach Model (Campbell et al, 2006; Foster & Trimm, 2008) describes grandiose narcissists as much more sensitive to and motivated by potential reward than by potential punishment. This creates a tendency toward approach-oriented social behavior (Foster, Misra, & Reidy, 2009), which may explain why those high in grandiose narcissism generate more content (Buffardi & Campbell, 2008; Mehdizadeh, 2010; Poon & Leung, 2011)—especially self-promoting content (Buffardi & Campbell, 2008; Mehdizadeh, 2010)—with relatively little concern for privacy (Smith, Mendez, & White, 2014; Utz & Kramer, 2009) on social media sites. In contrast, vulnerable narcissists, who are high in both approach and avoidance motivation (Foster & Trimm, 2008), are more cautious about obtaining praise, showing more concern for privacy (Ahn, Kwolek, & Bowman, 2015) and putting more effort into impression management (i.e., taking multiple selfies before picking one and cropping and editing pictures) than grandiose narcissists (McCain et al, 2016).…”
