Nostalgia increases punitiveness by intensifying moral concern.

We addressed the relation between nostalgia and moral judgment or behavior. We hypothesized that nostalgia, a social emotion, increases moral concern (H1), nostalgia intensifies punitiveness against moral transgressors (H2), and that the nostalgia-punitiveness link is mediated by moral concern (H3). We conducted three cross-sectional (Studies 1, 2, 4) and one experimental (Study 3) investigations (N = 1145). The investigations, involving distinct operationalizations of the relevant constructs (nostalgia, moral concern, punitiveness) and diverse samples (U.S., Canadian, and European Prolific workers, French business school students, Dutch community members), yielded results consistent with the hypotheses. Nostalgia keeps one's moral compass in check. The findings enrich the emotions and morality literatures.

Nostalgia, Ritual Engagement, and Meaning in Life.

Rituals are pervasive and beneficial. Little is known, however, about causes or antecedents of ritual engagement. We hypothesized that nostalgia-a sentimental longing for one's past-promotes ritual engagement, which in turn augments meaning in life. We tested this hypothesis in five methodologically diverse studies. In Study 1 (N = 311), nostalgia was positively associated with ritual engagement. In Study 2 (N = 188), nostalgia promoted ritual engagement, and in Study 3 (N = 296), it did so over engagement in a neutral task. In Study 4 (N = 252), nostalgia predicted later ritual engagement but not vice versa, convergent with Studies 2 and 3. Furthermore, nostalgia prospectively predicted meaning in life through specific ritualistic behaviors during a traditional festival. Finally, in Study 5 (N = 166), experimentally manipulated ritual engagement augmented meaning in life. As hypothesized, nostalgia advances ritual engagement, contributing to a meaningful life.

Pancultural nostalgia in action: Prevalence, triggers, and psychological functions of nostalgia across cultures.

Nostalgia is a social, self-relevant, and bittersweet (although mostly positive) emotion that arises when reflecting on fond past memories and serves key psychological functions. The majority of evidence concerning the prevalence, triggers, and functions of nostalgia has been amassed in samples from a handful of largely Western cultures. If nostalgia is a fundamental psychological resource, it should perform similar functions across cultures, although its operational dynamics may be shaped by culture. This study (N = 2,606) examined dispositional nostalgia, self-reported triggers of nostalgia, and functions of experimentally induced nostalgia in young adults across 28 countries and a special administrative region of China (i.e., Hong Kong). Results indicated that nostalgia is frequently experienced across cultures, albeit better valued in more-developed countries (i.e., higher national wealth and life-expectancy). Nostalgia is triggered by psychological threats (especially in warmer countries), sensory stimuli (especially in more-developed countries), and social gatherings (especially in less-developed countries). The positive or negative affect prompted by experimentally induced nostalgia varied by country, but was mild overall. More importantly, recalling a nostalgic (vs. ordinary) memory increased social connectedness, self-continuity, and meaning in life across cultures. In less-developed countries, recalling an ordinary memory also conferred some of these functions, reducing the effect size of nostalgia. Finally, recalling a nostalgic (vs. ordinary) memory augmented state satisfaction with life in countries with lower quality of living (i.e., lower life-expectancy and life-satisfaction). Overall, findings confirm the relevance of nostalgia across a wide range of cultures and indicate cultural nuances in its functioning. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The utility of nostalgia for unhealthy populations: A systematic review and narrative analysis.

Nostalgic reverie (i.e. sentimental longing) has received increased attention as a predictor of health and well-being, but only a handful of reviews have summarized this literature. The available reviews (Dementia: The International Journal of Social Research and Practice, 19, 2020, 330; Intimations of nostalgia: Multidisciplinary explorations of an enduring emotion, Bristol University Press, 2022) left a critical gap in explicating the function of nostalgia among people engaged in unhealthy behaviour. In the current systematic review and narrative analysis, we sought to answer whether and under what conditions emotion serves to help or hinder people engaged in unhealthy behaviours in terms of taking action to change. We identified 14 studies and categorized them into two themes. In Theme I, nostalgising about a time in one's life when one was healthier motivated both readiness to change and action to change unhealthy behaviour. In Theme II, nostalgizing about the perceived benefits of engaging in unhealthy behaviour (e.g. social connectedness related to drinking) was associated with the continuance or acceleration of the unhealthy behaviour. This review highlights not only the presence of a link between nostalgia and unhealthy behaviour but also that the content of one's nostalgising matters for understanding whether the unhealthy behaviour is undermined or bolstered.

Trajectory of Nostalgia in Emerging Adulthood.

We examined the change and stability of nostalgia in emerging adulthood. We followed 327 students through their 4 university years with six assessments. Nostalgia demonstrated moderate rank stability (r = .25-.79). A Trait-State-Occasion model analysis indicated that the stable trait component, slowing-change trait component, and state component explained 37% to 43%, 10% to 27%, and 29% to 49% of variation in nostalgia on specific occasions, respectively. Longitudinal multilevel analysis revealed that the mean nostalgia level declined across university years. Greater intensity of negative life events at the start of university was associated with higher initial nostalgia and slower decline of it, while the emotion intensified when experiencing more negative life events. Nostalgia in emerging adulthood displays moderate stability, with negative life events contributing to the shape of its trajectory.

More than a barrier: Nostalgia inhibits, but also promotes, favorable responses to innovative technology.

While technology is moving forward, people are looking back to the past. How does nostalgia influence responses (i.e., attitudes and behavior) to innovative technology? We postulated a dual-pathway model, according to which nostalgia, as a social emotion, would foster social connectedness that would be associated with or lead to favorable responses to innovative technology. At the same time, nostalgia, as an emotion that places a high premium on the past, would be associated with or lead to unfavorable responses to innovative technology (i.e., artificial intelligence or fifth-generation wireless communication) via skepticism about change. We provided support for the dual-pathway model in seven studies (N = 1,629), using correlational and experimental methods, operationalizing the constructs in diverse ways, and testing participants from three cultures (China, United Kingdom, and United States). The findings contribute to the vibrant conversation on human-technology relationship. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Cultural distances between home and host countries inspire sojourners to engage in intercultural exchange upon repatriation.

We examine how cultural distance between sojourners' country of origin and their host country influences their engagement in intercultural exchange upon return. One might expect intercultural exchange to be much harder between culturally-distant countries than culturally-close ones, given that the former vary more in norms or expected behaviors from one's home country. Our novel theorizing, however, leads to precisely the opposite expectations. In particular, we hypothesized that cultural distance between the repatriates' home and host countries would be positively associated with being inspired by the host culture. In turn, this heightened inspiration would predict an increased sharing of knowledge about the host culture upon returning home (intercultural exchange). We combined measurement-of-mediation (Study 1) and experimental-causal-chain (Studies 2-3) approaches to test and confirm these hypotheses in three large samples of repatriates. We first examined whether cultural distance predicted greater intercultural exchange via repatriates' heightened inspiration (Study 1). We then tested the individual links in this postulated causal chain. In Study 2, a quasi-experiment, we examined the causal path from cultural distance to inspiration. In Study 3, we experimentally manipulated inspiration to test its causal effect on intercultural exchange. The findings advance theory and application around multicultural experience and intercultural exchange.

Nostalgia Promotes Parents' Tradition Transfer to Children by Strengthening Parent-Child Relationship Closeness.

Parental tradition transfer to children is pivotal for their socialization, identity formation, and culture perpetuation. But what motivates parents to transfer traditions to their children? We hypothesized that nostalgia, an emotion strengthening interpersonal bonds, would promote tradition transfer through parent-child relationship closeness. We tested these hypotheses using cross-sectional (Studies 1 and 4), cross-lagged (Study 2 and preregistered Study 5), and experimental (Studies 3 and 6) designs. In Studies 1 to 3, nostalgia was associated with, had lagged effect on, and promoted tradition transfer. In Studies 4-6, parent-child relationship closeness mediated the link between nostalgia and tradition transfer. The findings enrich our understanding of the vertical transmission of knowledge, customs, and values, offering insight into how intergenerational bonds are reinforced and cultural heritage is maintained.

Trait nostalgia: Four scales and a recommendation.

We review four established scales for measuring individual differences in trait-level nostalgia: the Nostalgia Inventory, the Southampton Nostalgia Scale, the Nostalgia Prototype Scale, and the Personal Inventory of Nostalgic Experiences. To examine their convergent validity, we re-analyzed data from a published study in which all four scales were administered simultaneously. Multi-group confirmatory factor analyses demonstrated that a one-factor model accurately described the interrelations among the four scales, and supported full metric and partial scalar invariance across U.S. and Chinese samples. When measuring trait nostalgia, we recommend that researchers also consider potential confounders. Specifically, we discuss the importance of controlling for other ways in which individuals habitually reflect on their past, including brooding rumination and upward self-referent counterfactual thinking.

Schizophrenia and Increased Distrust-Based Competitiveness in Interpersonal Interactions: A Serial Process Model.

BACKGROUND AND HYPOTHESIS: Game theory paradigms, such as the Prisoner's Dilemma Game (PDG), have been used to study nonclinical paranoia, though research using clinical populations has been scarce. We test our novel theoretical model that schizophrenia leads to competitiveness in interpersonal interactions, and that this link is serially mediated by trait paranoia, state paranoia, and distrust. STUDY DESIGN: In this quasi-experimental study, individuals with schizophrenia spectrum diagnoses with current persecutory delusions (n = 46) and a nonclinical control group (n = 43) played the PDG, and completed measures of trait paranoia, state paranoia, and distrust. STUDY RESULTS: Individuals with schizophrenia competed more in the PDG than the control group. Supporting our theoretical model, all direct effects were significant: schizophrenia was associated with higher trait paranoia (H1); trait paranoia predicted state paranoia in the PDG (H2); state paranoia in the PDG predicted distrust of the opponent in the PDG (H3); and distrust predicted competition in the PDG (H4). The hypothesized indirect effect of schizophrenia on competition in the PDG via trait paranoia, state paranoia, and distrust was supported in a serial mediation model (H5). CONCLUSIONS: The findings make clear theoretical and methodological contributions. We provide the first evidence for a theoretical process model by which schizophrenia leads to competitiveness in interpersonal interactions via trait paranoia, state paranoia, and distrust. Game theory paradigms, and the PDG in particular, are important for advancing theory and research on paranoia as it occurs in both clinical and nonclinical populations.

Nostalgia enhances route learning in a virtual environment.

Salient landmarks enhance route learning. We hypothesised that semantically salient nostalgic landmarks would improve route learning compared to non-nostalgic landmarks. In two experiments, participants learned a route through a computer-generated maze using directional arrows and wall-mounted pictures. On the test trial, the arrows were removed, and participants completed the maze using only the pictures. In the nostalgia condition, pictures were of popular music artists and TV characters from 5 to 10 years ago. In the control condition, they were recent pictures of these same artists and characters. In Experiment 1, in the test trial, participants in the nostalgia condition completed the maze faster than controls. Experiment 2 conceptually replicated these findings and extended them by exploring boundary conditions. Participants had to learn two mazes sequentially. In Maze 1, we placed nostalgic/control landmarks only at non-decision points (whereas we placed them at decision points in Experiment 1). In Maze 2, we placed nostalgic/control landmarks at decision points during acquisition but removed them in the test trial (whereas they were present in the test trial in Experiment 1). In both mazes, participants in the nostalgia (compared to control) condition completed the test trial faster.

Distress prospectively predicts higher nostalgia, and nostalgia prospectively predicts lower distress.

OBJECTIVE: We were concerned with the relation between distress and nostalgia. At the state level, extensive research has established that momentary nostalgia is evoked by (experimentally manipulated) distress. However, at the trait level, the directionality of this relation is unclear. We conducted a longitudinal study to clarify the directional relation between these two constructs. METHOD: We surveyed first-year university students (N = 3167) twice across six months. We assessed nostalgia, psychological distress (depression), and physical distress (somatization) at both timepoints. We also assessed Big Five personality at the first timepoint. RESULTS: Initial distress prospectively predicted increased nostalgia, and initial nostalgia prospectively predicted reduced distress, six months later and independently of the Big Five. CONCLUSIONS: Habitual nostalgia follows rather than precedes naturalistically occurring distress and serves to relieve it.

Food-evoked nostalgia.

In three studies, we examined food as an elicitor of nostalgia. Study 1 participants visualised eating either a nostalgic or regularly consumed food. Study 2 participants visualised consuming 12 foods. Study 3 participants consumed 12 flavour samples. Following their food experiences, all participants responded to questions regarding the profile of food-evoked nostalgia (i.e. autobiographical relevance, arousal, familiarity, positive and negative emotions) and several psychological functions (i.e. positive affect, self-esteem, social connectedness, meaning in life). Study 2 and 3 participants also reported their state nostalgia. Results revealed that food is a powerful elicitor of nostalgia. Food-evoked nostalgia has a similar contextual profile to previously examined elicitors, but is a predominantly positive emotional experience. Food-evoked nostalgia served multiple psychological functions and predicted greater state nostalgia.

Dispositional forgiveness buffers paranoia following interpersonal transgression.

OBJECTIVE: To test a novel proposition that dispositional forgiveness has the unrecognized benefit of buffering feelings of paranoia following negative interpersonal experiences and interpersonal transgressions. METHODS: In Study 1 (N = 128), we used an experimental paradigm, the Prisoner's Dilemma Game (PDG), to test the premise that an interpersonal transgression increases state paranoia. Study 2 (N = 180) used a longitudinal design to test the central proposition that dispositional forgiveness buffers state paranoia following naturally occurring difficult (vs pleasant) interpersonal events. Study 3 (N = 102) used a novel experimental paradigm to determine the causal effect of manipulating forgiveness on paranoia. RESULTS: In Study 1, interpersonal transgressions in the PDG increased paranoia. In Study 2, paranoia was higher following difficult (rather than pleasant) events, and higher levels of dispositional forgiveness moderated the negative effect of difficult events on paranoia. In Study 3, there was a causal effect of forgiveness on (reduced) paranoia. CONCLUSIONS: This is the first evidence that (1) interpersonal transgressions increase paranoia, (2) high dispositional forgiveness moderates the deleterious effect of interpersonal transgression on paranoia, and (3) dispositional forgiveness is causally related to less paranoia.

Nostalgia as motivation.

Nostalgia, an approach-oriented emotion, has motivational consequences. In particular, nostalgia raises optimism and inspiration, strengthens the pursuit of one's important goals, appears to encourage financial risk-taking activates the intrinsic or authentic self, and galvanizes the desire to change one's addictive behavior. Nostalgia, a past-oriented emotion, has strong implications for the future. We discuss boundaries of these effects, highlight lacunae in the literature, and point to promising research directions.

Induction of spatial anxiety in a virtual navigation environment.

Spatial anxiety (i.e., feelings of apprehension and fear about navigating everyday environments) can adversely impact people's ability to reach desired locations and explore unfamiliar places. Prior research has either assessed spatial anxiety as an individual-difference variable or measured it as an outcome, but there are currently no experimental inductions to investigate its causal effects. To address this lacuna, we developed a novel protocol for inducing spatial anxiety within a virtual environment. Participants first learnt a route using directional arrows. Next, we removed the directional arrows and randomly assigned participants to navigate either the same route (n = 22; control condition) or a variation of this route in which we surreptitiously introduced unfamiliar paths and landmarks (n = 22; spatial-anxiety condition). The manipulation successfully induced transient (i.e., state-level) spatial anxiety and task stress but did not significantly reduce task enjoyment. Our findings lay the foundation for an experimental paradigm that will facilitate future work on the causal effects of spatial anxiety in navigational contexts. The experimental task is freely available via the Open Science Framework ( https://osf.io/uq4v7/ ).

Collective nostalgia: Triggers and consequences for collective action intentions.

Global trends surveys suggest that collective nostalgia for one's country is widespread. Moreover, research indicates that collective nostalgia is used by populist radical-right parties to mobilize their voters against immigration. We focused on antecedents of collective nostalgia and its consequences for collective action in the context of national identity. In particular, we hypothesized that collective nostalgia for the country's past is triggered by a sense of collective discontinuity and subsequently engenders collective action intentions to protect the national ingroup and limit the presence of immigrant outgroups. We tested this hypothesis in a three-wave longitudinal cross-lagged panel study (N = 1489) among native Dutch majority members. The results were consistent with the hypothesis. The findings highlight the relevance of collective nostalgia as an emotional response to collective discontinuity that drives collective action intentions aimed at protecting ingroup continuity. We discuss implications of the findings for the literature on collective nostalgia and group dynamics as well as the broader literature on collective action and provide directions for future research.

Self-Continuity.

Self-continuity is the subjective sense of connection between one's past and present selves (past-present self-continuity), between one's present and future selves (present-future self-continuity), or among one's past, present, and future selves (global self-continuity). We consider the motivational character of the three forms of self-continuity, their regulatory properties, and the internal or external factors that consolidate them. We also review their consequences for attitudes and judgments or decisions, motivation, intentions and behavior, and psychological and physical health. We further detail the psychological and behavioral benefits of self-discontinuity (i.e., a sense of disconnect among temporal selves). We next turn to the brain regions that are activated synchronously with self-continuity. We consider developmental perspectives on self-continuity, discuss collective self-continuity (along with its consequences and regulatory properties), and elaborate on cultural differences in self-continuity. This inaugural Annual Reviews chapter demonstrates the breadth, excitement, and sense of synergy among self-continuity researchers and points to promising research directions.

Patterns of brain activity associated with nostalgia: a social-cognitive neuroscience perspective.

Nostalgia arises from tender and yearnful reflection on meaningful life events or important persons from one's past. In the last two decades, the literature has documented a variety of ways in which nostalgia benefits psychological well-being. Only a handful of studies, however, have addressed the neural basis of the emotion. In this prospective review, we postulate a neural model of nostalgia. Self-reflection, autobiographical memory, regulatory capacity and reward are core components of the emotion. Thus, nostalgia involves brain activities implicated in self-reflection processing (medial prefrontal cortex, posterior cingulate cortex and precuneus), autobiographical memory processing (hippocampus, medial prefrontal cortex, posterior cingulate cortex and precuneus), emotion regulation processing (anterior cingulate cortex and medial prefrontal cortex) and reward processing (striatum, substantia nigra, ventral tegmental area and ventromedial prefrontal cortex). Nostalgia's potential to modulate activity in these core neural substrates has both theoretical and applied implications.
