Nostalgia counteracts self‐discontinuity and restores self‐continuity

Nostalgia is a resource that functions, in part, as a response to self‐discontinuity and a source of self‐continuity. We tested and supported this regulatory role of nostalgia in the tradition of establishing a causal chain. In Study 1, we examined the naturalistic association between events precipitating self‐discontinuity and nostalgia. Self‐discontinuity, especially when stemming from negative life events, was associated with higher proneness to nostalgia. In Study 2, we experimentally induced negative self‐discontinuity (i.e. relatively disruptive), positive self‐discontinuity (i.e. relatively non‐disruptive) or self‐continuity (i.e. neutral non‐disruptiveness) and subsequently assessed state levels of nostalgia. Only negative self‐discontinuity evoked heightened nostalgia. In Study 3, we experimentally induced nostalgia (versus ordinary autobiographical recollection) and assessed self‐continuity. Nostalgia augmented self‐continuity. In Study 4, we experimentally induced nostalgia (versus ordinary autobiographical recollection versus positive autobiographical recollection) and assessed self‐continuity. Again, nostalgia augmented self‐continuity and did so above and beyond positive affect. Here, we ruled out demand characteristics as a rival hypothesis. Taken together, the findings clarify the role of nostalgia in the dynamic between self‐discontinuity and self‐continuity and elucidate the restorative properties of nostalgia for the self‐system.
