Nostalgia: Content, triggers, functions.

TLDR

Nostalgic recollections typically portray the self interacting with close others or significant events, emphasize positive emotions, and often frame earlier negative experiences as redeemed by later successes. Seven methodologically diverse studies examined three core questions about nostalgia, with the first two focusing on its content. The studies found that nostalgia is triggered by negative mood and loneliness, and that it strengthens social bonds, enhances self‑regard, and produces positive affect, marking important milestones in nostalgia research.

Abstract

Seven methodologically diverse studies addressed 3 fundamental questions about nostalgia. Studies 1 and 2 examined the content of nostalgic experiences. Descriptions of nostalgic experiences typically featured the self as a protagonist in interactions with close others (e.g., friends) or in momentous events (e.g., weddings). Also, the descriptions contained more expressions of positive than negative affect and often depicted the redemption of negative life scenes by subsequent triumphs. Studies 3 and 4 examined triggers of nostalgia and revealed that nostalgia occurs in response to negative mood and the discrete affective state of loneliness. Studies 5, 6, and 7 investigated the functional utility of nostalgia and established that nostalgia bolsters social bonds, increases positive self-regard, and generates positive affect. These findings demarcate key landmarks in the hitherto uncharted research domain of nostalgia.
