Results obtained with the sustainability-related donation task. A, Salivary OXT concentration and donations (Experiment 1). In the social frame (n = 32), participants who donated all of their money exhibited significantly higher endogenous OXT concentrations compared with participants who donated €9 or less. B, Effects of OXTIN on the donated amounts and the distribution profiles of donations (Experiment 2A). i, OXTIN more than doubled the sums donated in the social frame and substantially decreased donations in the ecological frame, while keeping constant the overall proportion of donated money to a charity. ii, OXTIN also tended to increase the number of participants who were willing to donate at least €1 to the social charity (83.33%) compared with PLCIN (58.3%). iii, In the ecological frame, the proportions of participants who donated at least €1 were identical in the PLCIN (80.77%) and OXTIN group (80.77%).
