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.

The power of the past: Nostalgia as a meaning-making resource

In three experiments we tested whether nostalgia bolsters meaning in life relative to two other modes of autobiographical thought: imagining a desired future experience and recalling a positive past experience. In Experiment 1 participants thought about a nostalgic or desired future experience and then completed a presence of meaning scale. Thinking about a nostalgic (compared to desired future) experience increased perceived presence of meaning. In Experiment 2 we examined whether nostalgia can additionally reduce the search for meaning. Participants thought about a nostalgic, desired future or recent positive experience, and then completed a search for meaning scale. Nostalgia, relative to both comparison conditions, decreased the search for meaning. Finally we tested whether, by virtue of its capacity to increase meaning, nostalgia can mitigate threats to meaning. In Experiment 3 participants were exposed to either absurd or representational art, under the guise that they would later have to interpret its meaning, and then thought about either a nostalgic or a recent positive experience. Meaning was subsequently measured. The absurd art interpretation condition decreased the perceived presence of meaning but nostalgic reflection attenuated this effect.     

Fighting ageism through nostalgia

Two experiments tested whether nostalgia is a resource for fighting ageism. In Experiment 1, younger adults who recalled a nostalgic (vs. ordinary) encounter with an older adult showed a more positive attitude towards older adults, mediated by greater inclusion of older adults in the self (IOGS). In Experiment 2, these findings were replicated and extended with a subtle nostalgia manipulation. Younger adults identified an older, familiar adult, before writing about an encounter with this person that was characterized by either central (e.g., keepsakes and childhood) or peripheral (e.g., wishing and daydreaming) features of the construct of nostalgia (i.e., prototype). Participants who recalled a central (vs. peripheral) nostalgic encounter reported greater social connectedness, which predicted increased IOGS. In turn, increased IOGS was associated with a lower desire to avoid older adults. Several alternative explanations for the intergroup benefits of nostalgia were ruled out. The research established that nostalgia qualifies as a resource for combatting ageism.     

Nostalgia’s place among self-relevant emotions

How is nostalgia positioned among self-relevant emotions? We tested, in six studies, which self-relevant emotions are perceived as most similar versus least similar to nostalgia, and what underlies these similarities/differences. We used multidimensional scaling to chart the perceived similarities/differences among self-relevant emotions, resulting in two-dimensional models. The results were revealing. Nostalgia is positioned among self-relevant emotions characterised by positive valence, an approach orientation, and low arousal. Nostalgia most resembles pride and self-compassion, and least resembles embarrassment and shame. Our research pioneered the integration of nostalgia among self-relevant emotions.     

The past makes the present meaningful: nostalgia as an existential resource

The present research tested the proposition that nostalgia serves an existential function by bolstering a sense of meaning in life. Study 1 found that nostalgia was positively associated with a sense of meaning in life. Study 2 experimentally demonstrated that nostalgia increases a sense of meaning in life. In both studies, the link between nostalgia and increased meaning in life was mediated by feelings of social connectedness. Study 3 evidenced that threatened meaning increases nostalgia. Study 4 illustrated that nostalgia, in turn, reduces defensiveness following a meaning threat. Finally, Studies 5 and 6 showed that nostalgia disrupts the link between meaning deficits and compromised psychological well-being. Collectively, these findings indicate that the provision of existential meaning is a pivotal function of nostalgia.     

Hanin: Nostalgia among Syrian refugees

We examined the psychological functions of nostalgia (hanin in Arabic) among Syrian refugees residing in Saudi Arabia, who were forcibly displaced during the Syrian civil war. Forced displacement entails disruption, loss, and mourning, creating a salient contrast between one's past and present circumstances, which could attenuate the benefits of nostalgia. Studying this population thus affords a strong test of the boundaries of nostalgia's functionality. We experimentally induced nostalgia via vivid autobiographical recall and then assessed various psychological functions, as well as current affect. A supplemental objective was to examine the role of dispositional resilience. Most established benefits of nostalgia also accrued to Syrian refugees. However, contrary to previous findings, nostalgia decreased optimism, highlighting the limits of its palliative capacity among displaced individuals. As hypothesized, the impact of nostalgia was moderated by dispositional resilience, which acted as a catalyst of the emotion's benefits and as an inhibitor of its costs.     

Interindividual-intergroup discontinuity reduction through the anticipation of future interaction

Consistent with the role of a long-term perspective in reducing the tendency of intergroup relations to be more competitive than interindividual relations in the context of noncorrespondent outcomes, an experiment demonstrated that anticipated future interaction reduced intergroup but not interindividual competitiveness. Further results indicated that the effect was present only for groups composed of members high in abstractness (Openness-Intellect on the Big 5 Inventory and Intuition on the Myers-Briggs Type Inventory) who trusted their opponents.     

Interindividual-intergroup discontinuity as a function of trust and categorization: the paradox of expected cooperation

Two experiments used a 3-choice variation of the prisoner's dilemma game to explore the paradoxical implications of expected cooperation of other groups and individuals for competitiveness and cooperativeness. Experiment 1 found that an experimental manipulation of opponent trustworthiness influenced the tendency of both groups and individuals to cooperate but had no significant effect on the tendency of groups and individuals to compete--possibly because of the perceived unfairness of competing with a trustworthy other. Experiment 2 found that an experimental manipulation of categorization increased the tendency of same-category groups and individuals to cooperate (as in Experiment 1) and also increased the tendency of same-category groups, but not individuals, to compete (unlike in Experiment 1). It was further found that the tendency of same-category groups to compete more than same-category individuals was relatively stronger for participants high in guilt proneness.     

Interindividual‐intergroup discontinuity as a joint function of acting as a group and interacting with a group

An experiment assessed the prisoner's dilemma game (PDG) choices of a set of three persons who interacted with another supposed set of three persons. There were four conditions: (1) group‐on‐group (both three‐person sets constrained by a majority vote), (2) group‐on‐one (only own three‐person set constrained by a majority vote), (3) one‐on‐group (only other three‐person set constrained by a majority vote), (4) one‐on‐one (neither three‐person set constrained by a majority vote). The four conditions were compared with three orthogonal contrasts. Consistent with the assumption that interindividual interactions are less competitive than interactions involving groups, the first contrast indicated that there were fewer competitive choices in the one‐on‐one condition than in the other three conditions pooled. Consistent with the assumption that competitiveness can flow either from acting as a group or interacting with a group, the second contrast found no significant difference between the group‐on‐one and one‐on‐group conditions. Finally, consistent with the assumption that the interindividual‐intergroup discontinuity effect is a joint function of acting as a group and interacting with a group, the third contrast revealed that there were more competitive choices in the group‐on‐group condition than in the one‐on‐group and group‐on‐one conditions pooled.

Sociality and intergenerational transfer of older adults’ nostalgia

Interest in nostalgia has blossomed, yet its nature in older adulthood and potential for intergenerational transfer to younger adults has remained neglected. In Experiment 1, we focused on the content of older adults’ nostalgic (vs. ordinary) recollections and asked whether older adults’ nostalgia could be transferred to younger adults. We showed that nostalgia expressed in older adults’ narratives was positively associated with nostalgia reported by young-adult readers. In Experiment 2, undergraduates read a nostalgic or ordinary narrative written by an older adult. Then they rated their own nostalgia as well as their perceived social connectedness, self-continuity, and meaning in life. Exposure to older adults’ nostalgic (vs. ordinary) narratives promoted concurrent nostalgia among young adults, along with associated psychological benefits (social connectedness, self-continuity, meaning). The findings illustrate the potential for intergenerational transfer of nostalgia through written narratives, and attest to the universality of nostalgic themes across younger and older adults.
