However, individual reactions to the topics of climate change and sustainability, including the propensity to engage in sustainable behavior in daily life, have been increasingly colored by political ideology. While an emerging body of work recognizes the important role of positive emotions in driving sustainable behaviors, prior research has not examined whether or how specific positive emotions might differentially lead to sustainable behavior change among those with differing political ideologies. The present research demonstrates that the positive emotion of hope differentially affects the willingness of conservatives versus liberals to engage in sustainable behaviors. Five studies measure and manipulate political ideology and use various operationalizations of sustainable behavior to demonstrate that activating hope leads conservatives to increase their sustainable intentions and behaviors relative to their baseline tendencies (neutral condition) and other comparison emotions (nostalgia, pride). This effect occurs because hope increases conservatives’ desire for societal transformation and strengthens their perceptions of collective efficacy. These findings offer practical insights and advance the literatures on sustainable behavior, political ideology, and emotion.</div></div>","PeriodicalId":48439,"journal":{"name":"Journal of Environmental Psychology","volume":"110 ","pages":"Article 102945"},"PeriodicalIF":7.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146173119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results indicate that individual noise sensitivity has only a limited influence on annoyance and coping.

High noise sensitivity is associated with avoidance behaviour, while cognitive coping is used less frequently.

We expected that direct actions which successfully communicate a utopian vision can increase access to desirable cognitive alternatives in observers; a so-called “prefigurative effect”. We hypothesized that direct actions with this prefigurative effect (versus comparable non-direct actions) will be more strongly supported, perceived as more legitimate and efficacious, elicit less negative and more positive emotions, and lead to a higher propensity to participate in and stronger solidarity with the movement. We also investigated downstream effects on perceptions of a traffic-reduced future and policy support. To test our hypotheses, we conducted two pre-registered online experiments in Germany (<em>N</em><sub>total</sub> = 645), in which we varied direct vs. non-direct version of a bicycle, parking, and automobility action. In both studies, the direct bicycle and direct parking actions increased access to cognitive alternatives but only the direct bicycle action consistently increased hope, support for the activists, and support for the action. This suggests that confrontative collective action which is (perceived to be) direct and prefigurative is more likely to elicit positive reactions than when it is not, although there seem to be additional factors at play. Taken together, our results speak to the value of embracing direct action and prefigurative politics both in research and practice.</div></div>","PeriodicalId":48439,"journal":{"name":"Journal of Environmental Psychology","volume":"110 ","pages":"Article 102851"},"PeriodicalIF":7.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146173207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined between- and within-person actor and partner effects of dietary motives on meat consumption in general and across 28 shared meals (7203 ratings in total) in 272 romantic partners. We found that the most important motives for higher personal meat consumption were the beliefs that meat tastes good, is necessary for health, and is natural, whereas concerns about ethical impacts for the environment and animals were the most important factors for lower consumption. People ate more meat if their partners viewed meat as necessary and tasty. Only high meat eating partners ate more meat when they or their partners believed it was normal, or their partners believed it was natural, but ate less when their partners were concerned about the environment. They further felt less capable of preparing plant-based meat alternatives during meals in which their partners ate less meat. Only low meat eating partners ate more meat when they felt pressured or when their partner valued health or felt incapable of preparing alternatives. These results demonstrate how interpersonal processes shape sustainability-related behaviors that involve conflicting motives and preferences between romantic partners, such as meat consumption.
