The impact of place and legacy framing on climate action: A lifespan approach

biophilia attitudes were revealed to have a significant effect on donations when controlling for exposure to the Place induction, b = .260, t(689) = 7.06, p < .001. Step 4 revealed that the effect of the Place induction on donations was partially mediated by increases in biophilia attitudes: b = .073, t(689) = 1.97, p = .049. Mediation was again confirmed by a bias-corrected bootstrap- ping procedure using 10,000 samples [38] (Hayes, 2013). This analysis showed that the indirect effect of the Place induction on donations through biophilia was significant, with a 95% confi- dence interval (CI) that excluded zero (β = 0.058, 95% CI = [0.018, 0.100]). We also assessed whether greater biophilia would mediate the effect of the Place induction on behavioral intentions. In step 1 of this analysis, we revealed that exposure to the Place induction had a significant effect on behavioral intentions, b = .137, t(681) = 3.62, p < .001. In step 2, the Place induction was found to have a significant effect on biophilia attitudes, b = .111, t(690) = 2.93, p = .004. In step 3, biophilia attitudes were revealed to have a significant effect on behavioral intentions when controlling for exposure to the Place induction, b = .424, t(680) = 12.26, p < .001. Step 4 revealed that the effect of the Place induction on individuals’ behavioral intentions was partially mediated by increases in biophilia attitudes: b = .092, t(680) = 2.65, p = .008. Mediation was again confirmed by a bias-corrected bootstrapping procedure

using 10,000 samples (Hayes, 2013). This analysis showed that the indirect effect of the Place induction on behavioral intentions through biophilia was significant, with a 95% confidence interval (CI) that excluded zero (β = 0.093, 95% CI = [0.028, 0.160]). To further explore the relationships among these variables, four additional parallel media- tion analyses including both mediators simultaneously were conducted and are available in the supplementary material (S3 File).
