Curiosity as a metacognitive feeling

Curious information-seeking is known to be a key driver of learning, but characterizing this important psychological phenomenon remains a challenge. In this article, we argue that this requires qualifying the relationships between metacognition and curiosity. The idea that curiosity is a metacognitive competence has been resisted: many researchers have assumed both that young children and non-human animals can be genuinely curious, and that metacognition requires conceptual and culturally situated resources that are unavailable to young children and non-human animals. We suggest that this resistance is unwarranted given accumulating evidence that metacognition can be deployed procedurally, and defend the view that curiosity is a metacognitive feeling. Our metacognitive view singles out two monitoring steps as a triggering condition for curiosity: evaluating one’s own informational needs, and predicting the likelihood that explorations of the proximate environment afford sizeable information gains. We review empirical evidence and computational models of curiosity, and show that they fit well with this metacognitive account, while on the contrary, they remain difficult to explain by a competing account according to which curiosity is a basic attitude of questioning. Finally, we propose a new way to construe the relationships between curiosity and the human-specific communicative practice of questioning, discuss the issue of how children may learn to express their curiosity through interactions with others, and conclude by briefly exploring the implications of our proposal for educational practices.
