Kaspar Hauser experiment

Quick Reference

An experiment in which an animal is reared in isolation from members of its own species (conspecifics), for example, the experiments carried out in the 1950s by the British ethologist William H. Thorpe (1902–86) in which birds were reared in isolation to determine which aspects of their songs are innate. See also feral child, Psammetichus experiment. [Named after Kaspar Hauser (?1812–33), a teenage boy who appeared mysteriously in Nuremberg in 1828 and was believed to be a feral child, having grown up virtually without human contact]
