There has been considerable interest in empirical research on epistemic emotions, i.e., emotions related to knowledge-generating qualities of cognitive tasks and activities such as curiosity, interest, and surprise. One big challenge when studying epistemic emotions is systematically inducting these emotions in restricted experimental settings. The current study created a novel stimulus set called Magic Curiosity Arousing Tricks (MagicCATs): a collection of 166 short magic trick video clips that aim to induce a variety of epistemic emotions. MagicCATs are freely available for research and can be used in a variety of ways to examine epistemic emotions. Rating data also support that the magic tricks elicit a variety of epistemic emotions with sufficient inter-stimulus variability, demonstrating good psychometric properties for their use in psychological experiments.

Epistemic emotions refer to a group of emotions which are related to the knowledgegenerating qualities of cognitive tasks and activities (Brun, Doğuoğlu, & Kuenzle, 2008; Muis, Chevrier, & Singh, 2018). These emotions typically include surprise, curiosity and interest. Recent studies have revealed that these epistemic emotions have profound implications for cognitive processing * Hiroki Ozono
