# Curiosity

Curiosity is used to denote the desire to investigate, gain knowledge or information, and, in an evolutionary context, is attributed as a major driving force behind human development.

One theory of curiosity (Curiosity-drive theory) states that it is a natural response to a disruption in the environment and thus of one’s cognitive process, and thus an attempt to understand the unfamiliar.

A second theory (Optimal-arousal theory) justifies the presence of curiosity even in the absence of uncertain or ambiguous situations, and it dictates that one can be motivated to maintain a pleasurable sense of arousal through exploratory behaviours.
