“…Shared positive feelings may foster prosocial behaviors by activating neural systems (i.e., ventral striatum, anterior cingulate cortex, medial orbitofrontal cortex, thalamus, amygdala, and anterior insula) that support reward processing (Berridge & Kringelbach, 2015; Haber & Knutson, 2010). Prosocial behaviors including altruistic giving (e.g., spending money on others and giving to charities), empathic validation, emotional support, and cooperation activate reward network hubs such as the ventral striatum, among others (Declerck, Boone, & Emonds, 2013; Dunn, Aknin, & Norton, 2008; Harbaugh, Mayr, & Burghart, 2007; Inagaki & Eisenberger, 2012; Izuma, Saito, & Sadato, 2010; Morelli, Torre, & Eisenberger, 2014), that support reward processing as well as emotion and empathy more broadly (Cloutier, Heatherton, Whalen, & Kelley, 2008; Decety & Jackson, 2004; Mobbs et al., 2009; Morelli, Sacchet, & Zaki, 2015; Sescousse, Caldu, Segura, & Dreher, 2013). …”
