Curiosity carry-over effect

Abstract

Curiosity is a powerful source of motivation and allows us to explore and acquire knowledge without relying on extrinsic incentives. So far, studies have mostly focused on the curiosity felt towards a specific object. Using a paradigm that sequentially activates curiosity on a trial-by-trial basis with trivia questions, we showed that the curiosity of one trial carries over to the next trial, even if each trial presents completely independent information. This carry-over effect was observed both when curiosity was measured through self-reports and a behavioral task (i.e. willingness-to-pay task). The results were also replicated when participants’ curiosity was not resolved, eliminating the role of general positive emotions. Theoretical implication of this carry-over effect was discussed.
