A feral child (also called wild child) is a young individual who has lived isolated from human contact from a very young age, with little or no experience of human care, social behavior, or language. The term is used to refer to children who have suffered severe abuse or trauma before being abandoned or running away. They are sometimes the subjects of folklore and legends, often portrayed as having been raised by animals. While there are many cases of children being found in proximity to wild animals, there are no eyewitness accounts of animals feeding human children.
Feral children lack the basic social skills that are normally learned in the process of enculturation. For example, they may be unable to learn to use a toilet, have trouble learning to walk upright after walking on fours all their lives, or display a complete lack of interest in the human activity around them. They often seem mentally impaired and have almost insurmountable trouble learning a human language. The impaired ability to learn a natural language after having been isolated for so many years is often attributed to the existence of a critical period for language learning, and taken as evidence in favor of the critical period hypothesis.
There is little scientific knowledge about feral children. One of the best-documented cases has supposedly been that of sisters Amala and Kamala, described by Reverend J. A. L. Singh in 1926 as having been "raised by wolves" in a forest in India. French surgeon Serge Aroles, however, has persuasively argued that the case was a fraud, perpetrated by Singh in order to raise money for his orphanage. Child psychologist Bruno Bettelheim states that Amala and Kamala were born mentally and physically disabled. Yet other scientific studies of feral children exist, such as the case of Genie.
Prior to the 1600s, feral and wild children stories were usually limited to myths and legends. In those tales, the depiction of feral children included hunting for food, running on all fours instead of two, and not knowing language.
