Reliving the Good Old Days: Nostalgia Increases Psychological Wellbeing Through Collective Effervescence

Abstract

Nostalgia, a sentimental longing for one’s past, is associated with, or confers, psychological wellbeing (PWB). We identified a mechanism for this link: collective effervescence, a potent sense of connection to those present in an assembly and a sensation of transcendence (i.e., feeling that an experience is special or sacred). In six studies, involving measurement-of-mediation and experimental-causal-chain designs, nostalgia was associated with, and led to, higher PWB via collective effervescence. In Study 1, nostalgia was related to PWB through collective effervescence at the dispositional level. In Study 2, induced collective effervescence increased PWB. In Studies 3a–3c, induced nostalgia led to greater PWB due to collective effervescence. In Study 4, induced nostalgia increased PWB due to collective effervescence even when controlling for authenticity, an alternate mediator.
