Curiosity is a universal and malleable positive character strength. It has been linked to physical, social, emotional, and psychological well-being, academic success, and success in adulthood. Curiosity is especially important in early childhood because this is a critical stage of development when children’s curiosity is still abundant and organic. But for all its value, curiosity remains under-recognized and under-studied. There is no universally agreed upon definition of curiosity in adults or children. As a result, the research community has varying opinions on how to define, measure, and enhance curiosity. And in many current day classrooms, an overly rigid top-down structure contributes to a disconcerting trend of diminishing curiosity as children grow older. Reviewing the scientific research across various fields, I describe seven psychological constructs (attention, novelty, solitude, inquiry, exploration, surprise, and awe) that can foster curiosity behaviors. I designed a Curiosity Toy Kit incorporating these seven curiosity components to be used as positive interventions for enhancing curiosity in early childhood, when children are 5-6 years old and entering formal education. Adults can use the Curiosity Toy Kit to encourage children to develop positive curiosity behaviors, helping them to flourish in school and beyond.
