ABSTRACTWe examined whether enhancing the emotionality of a referent public good influences the subsequent valuation of a target public good. We predicted that it would and that the directionality of its impact would depend on a fundamental cognitive process – categorisation. If the target and referent goods belong to the same domain, we expected that the effect on the target would be in the same direction as the emotional enhancement of the referent. However, if the target and referent goods belong (...) to different domains, we expected that the effect on the target would be either negligible or in the opposite direction to that of the emotional enhancement of the referent. In Experiment 1 we examined the impact of emotionally enhancing a referent public good on feelings towards a target public good, whereas in Experiment 2 on the willingness to contribute towards a target public good. The results support the predicted interaction, which was... (shrink)
