“Genie

In 1970 a child called Genie was admitted to a children’s hospital in Los Angeles. She was thirteen years old and had spent most of her life tied to a chair in a small closed room. Her father was intolerant of any kind of noise and had beaten the child whenever she made a sound. There had been no radio or television, and Genie’s only other human contact was with her mother who was forbidden to spend more than a few minutes with the child to feed her. Genie had spent her whole life in a state of physical, sensory, social and emotional deprivation.
As might be expected, Genie was unable to use language when she was first brought into care. However, within a short period of time, she began to respond to the speech of others, to try to imitate sound and to communicate. Her syntax remained very simple. However, the fact that she went on to develop an ability to speak and understand a fairly large number of English words provides some evidence against the notion that language cannot be acquired at all after the critical period.”
