Curiosity
Theories

Like other desires and need-states that take on an appetitive quality (e.g. food/hunger), curiosity is linked with exploratory behavior and experiences of reward. Curiosity can be described in terms of positive emotions and acquiring knowledge; when one's curiosity has been aroused it is considered inherently rewarding and pleasurable. Discovering new information may also be rewarding because it can help reduce undesirable states of uncertainty rather than stimulating interest. Theories have arisen in attempts to further understand this need to rectify states of uncertainty and the desire to participate in pleasurable experiences of exploratory behaviors.
