Genie's language acquisition also refined existing hypotheses and gave rise to additional hypotheses about what parts of language the right hemisphere could acquire after the critical period. [ 6 ] [ 91 ] Throughout the course of her linguistic development her language had remained largely congruous with adult split-brain and left ...
Genie is one of the best-known case studies of delayed language acquisition in a child outside of studies on deaf children. [2] [14] [15] Curtiss argued that, even if humans possess the innate ability to acquire language, Genie demonstrated the necessity of early language stimulation in the left hemisphere of the brain to start.
Curtiss and her team determined that Genie was most likely right-handed, but on dichotic listening tests they discovered that Genie, unlike most right-handed people, was right-hemisphere dominant for language; she had normal results for environmental sounds, proving that her brain was not simply reversed in dominance for language. Curtiss and ...
Genie's subsequent language-acquisition process was studied, whereby her linguistic performance, cognitive and emotional development was deemed abnormal. Genie was said [ by whom? ] to have right-hemisphere language, resembling other cases where language was acquired outside of the "critical period". [ 18 ]
The most well-documented case of a language-deprived child was that of Genie. Genie was discovered in 1970 in the family home, where she was recognized as highly abnormal. A social welfare agency took her into custody and admitted Genie into a hospital. Before discovery, Genie had lived strapped and harnessed into a chair.
Genie had spent the first 13 years of her life in severe isolation, and Fromkin and her associates hoped that her case would illuminate the process of language acquisition after the critical period. [7] [8] However, the study ended after rancorous disputes over Genie's care, and the loss of funding from the National Institute of Mental Health. [9]

Eric Heinz Lenneberg (19 September 1921 – 31 May 1975) was a linguist and neurologist who pioneered ideas on language acquisition and cognitive psychology, particularly in terms of the concept of innateness.
