Nostalgia across cultures

Nostalgia, a sentimental longing for one's past, has been garnering keen empirical attention in the psychological literature over the last two decades. After providing a historical overview, we place the emotion in cross-cultural context. Laypeople in many cultures conceptualize nostalgia similarly: as a past-oriented, social, self-relevant, and bittersweet emotion, but more sweet (positively toned) than bitter (negatively toned). That is, the nostalgizer reflects on a fond and personally important event—often their childhood or valued relationships—relives the event through rose-colored glasses, yearns for that time or relationship, and may even wish to return briefly to the past. Also, triggers of nostalgia (e.g., adverts, food, cold temperatures, loneliness) are similar across cultures. Moreover, across cultures nostalgia serves three key functions: it elevates social connectedness (a sense of belongingness or acceptance), meaning in life (a sense that one's life is significant, purposeful, and coherent), and self-continuity (a sense of connection between one's past and present self). Further, nostalgia acts as a buffer against discomforting psychological states (e.g., loneliness) similarly in varied cultural contexts. For example, (1) loneliness is positively related to, or intensifies, nostalgia; (2) loneliness is related to, or intensifies, adverse outcomes such as unhappiness or perceived lack of social support; and (3) nostalgia suppresses the relation between loneliness and adverse outcomes. Additionally, nostalgia facilitates one's acculturation to a host culture. Specifically, (1) nostalgia (vs. control) elicits a positive acculturation orientation toward a host culture; (2) nostalgia (vs. control) amplifies bicultural identity integration; and (3) positive acculturation orientation mediates the effect of host-culture nostalgia on bicultural identity integration. We conclude by identifying lacunae in the literature and calling for follow-up research.
