Scientific Terms

Curiosity, emotional behavior, inquisitive



Curiosity is behavioral trait that causes people or animals to be inquisitive. It causes us to explore, investigate and learn new things. Curiosity is the motivating force for us to experiment, experience and learn new things. It fuels our drive to make new discoveries in science and to explore new frontiers.

We are always curious about the new and novel events that occur around us. All of us, young and old, possess curiosity, to some degree. Curiosity has also been observed in many of the more intelligent animal species, such as the ape, monkey, cat, dog and even in fish, birds, insects amongst many others.

Curiosity is an important way for us to learn new things. It helps us, especially the young ones, learn about danger and how to avoid it. An example is when a child, curious about fire, tries to touch the flame on a candle and gets his fingers burnt! Of course, too much curiosity can be dangerous. An ignorant animal exploring a trap out of curiosity can end in captivity or even dead. As the saying goes, “Curiosity killed the cat!”
