Although many philosophers and environmental psychologists agree that progress toward a more ecologically conscious society depends upon individuals developing a sense of connectedness to nature, such agreement is of limited use if we do not understand how connectedness forms. The purpose of this review is to delineate the state of the psychological literature concerning the antecedents of connectedness to nature. The literature review is organized into three main sections: (1) situational contexts that influence connectedness; (2) individual difference predictors, such as demographic group membership, personality, or beliefs; and (3) internal psychological states that may explain psychological processes that result in connectedness. Major critiques of the extant literature and future directions are presented in a discussion following the body of the review. The primary implications highlighted by the review are a greater need for theories delineating the formation of connectedness, a greater focus on process, and increased differentiation between similar antecedents of connectedness.

Major environmental institutions around the globe are realising that the failing human–nature relationship is a root cause of environmental issues. Despite this shift in thinking, there is more work to be done to highlight the human–nature relationship as a tangible target for pro-environmental behaviour. This review argues for the importance of targeting human–nature relationships. It emphasises that nature connectedness, with its robust links to pro-environmental behaviour, is a useful operationalisation of such relationships. Following a review of recent references to the human–nature relationship in policy documents, this paper draws on theories of interpersonal relationships to illustrate how they can inform efforts to repair the human–nature relationship. Parallels between nature connectedness research and research on interpersonal relationships are highlighted. The potential for new routes to a closer human–nature relationship—including a more meaningful (e.g., intimate) engagement with nature, a cultural shift in support for human–nature relationships, fostering trust in nature and recognising reciprocity with nature—are noted. This review concludes that the human–nature relationship can be seen as an extension of interpersonal relationships, provides a tangible pathway to a sustainable future, and suggests that such explicit relationship-focused thinking can guide both policy and research.

Political marches are one of the most public and vocal means of engaging in collective action and can potentially build social movements by increasing the likelihood that bystanders become engaged with the social movement. Here, we conduct a trend study to test the impacts of two back-to-back highly visible large-scale climate change related marches on bystanders, targeting psychological drivers of collective action: efficacy beliefs, perceptions of others’ climate change activism and concerns, impressions of marchers, and behavioral intentions. Participants either completed a survey the day before the March for Science (n = 302) or several days after the People’s Climate March, which occurred a week after the first march (n = 285). Results suggest that the marches were at least partially effective: bystanders’ (a) collective efficacy beliefs and (b) impressions of marchers improved after the march. In contrast, marches were ineffective in increasing perceptions of others’ engagement with concern about climate change. We anticipated that political leaning of bystanders’ news sources would moderate effects of marches. Unexpectedly, collective efficacy beliefs improved among consumers of conservative, but not liberal, news. This unanticipated result is consistent with the notion that conservative news sources dedicated less coverage than liberal news sources to the marches prior to the marches (potentially leading to lower collective efficacy among those who consumed these sources), but that coverage afterwards was more equal across ideological bias of news sources. We also found that the more conservative the news sources consumed by an individual, the more negative impressions they had of marchers, and this relation was strongest among those that indicated, after the marches, that they had heard about the marches. These results on impressions are consistent with the notion that, when marches were covered, conservative news sources portrayed marchers relatively more negatively than liberal news sources. Overall, results suggest that marches can increase the likelihood that bystanders will participate in social movements via changes in psychological drivers of participation and the effects will likely depend upon political leanings of news sources via both whether sources mention the marches and how the sources cover the marches.

Recently, tourism scholars have recognized that travel can create transformation, including (1) personal benefits such as improved wellbeing and personal growth and (2) societal benefits such as increased open-mindedness and more positive pro-environmental attitudes, motivations, and behaviors. Expanding and integrating this research, this experimental study tests whether travel experiences, with eudaimonic elements of self-discovery and a sense of meaning, lead to these benefits and tests a proposed process where these experiences influence personal changes that subsequently create societal benefits. Specifically, using an online MTurk sample (n = 481) with a broad range of recent vacation experiences, we test whether (1) post-trip self-reflection on eudaimonic travel experiences (2) creates affective responses (3) that lead to self-transcendent changes and (4) subsequent post-trip philanthropy among recent travelers. Results of structural equation modeling indicate that philanthropic effects of travel were initiated by the eudaimonic self-reflections via eudaimonic affect and self-transcendent outcomes. This study contributes to the research linking eudaimonia and travel and provides insights into the ways that the travel industry can be harnessed as a potent tool for promoting personal meaning, self-transcendence, and prosocial outcomes.

There is growing recognition that our relationship with nature needs repairing. Two operationalizations of this construct within psychology are nature connectedness and relational environmental values. This review covers recent advances on both constructs. It outlines the growing evidence that both operationalizations are strong predictors of pro-environmental outcomes. It goes on to review what is known about the antecedents of the human-nature relationship and outlines three emerging principles about nature connectedness, in particular: (1) it largely operates like a true relationship, (2) it is a form of self-transcendence, and (3) it involves the self. Additionally, the review highlights recent paradigmatic shifts in the study of the human-nature relationship, shifting from studying associations at the individual level to instead focus on group-level processes.
