Post-manipulation ratings
donation behavior
Following this, all participants rated the dependent variables again and completed some exploratory measures; pro-environmental donation behavior; pro-environmental intention; pro-environmental impact-belief; anticipated warm glow; severity of environmental risks presented in the study; personal knowledge of the place imagined (for the complete survey, see Open Science Framework). Participants pro-environmental intention was measured with eight items, for example, “How likely is it that you will hang all your clothes on a clothesline, the next time you wash your clothes?”, and answered on a visual analogue scale- (VAS) scale ranging from 0 (Much more likely that I would do the non-environmental behavior (e.g., put them in the tumble dryer) to 100 (Much more likely that I would do the pro-environmental behavior). Their pro-environmental impact beliefs were also measured for the same eight behaviors as in the intention measure, participants answered “How environmentally effective do you think it would be to dry all your clothes on a clothesline rather than putting them in a dryer?” The participants rated all items on a VAS scale ranging from 0 (Will not make any difference at all) to 100 (Will make an extremely big difference).Participants' responses to the manipulation check and their vividness ratings both indicate that the extent of mental imagery used, and the vividness of mental images created, are in line with what was expected from our manipulations (see supplementary
