The Critical Period Hypothesis supported by Genie's case

The Critical Period Hypothesis (CPH), central to Lenneberg's 1967 work, explores the biological foundations of language acquisition, particularly in relation to growth and maturation. Lenneberg examines evidence from studies involving children with disabilities and neurological insights. Notably, the case of Genie, a girl confined and deprived of language exposure, serves as a poignant example that would later highlight the implications of the CPH. This paper delves into Lenneberg's theories and the significance of language development within a biological framework.
