He proposes that there is one critical phase between the age of two and about 13 years (before puberty) in which an individual is able to acquire first language (FL). Acquiring first language after this period is much more difficult and will never reach the perfect status of language acquired during the CP.
Does Genie support the critical period?
While Genie was able to learn some language after puberty, her inability to use grammar (which Chomsky suggests is what separates human language from animal communication) offers evidence for the critical period hypothesis.
What does the critical period hypothesis explain?
The critical period hypothesis says that there is a period of growth in which full native competence is possible when acquiring a language. This period is from early childhood to adolescence. The critical period hypothesis has implications for teachers and learning programmes, but it is not universally accepted.
What did Eric Lenneberg hypothesize on the critical period?
In his seminal book Biological Foundations of Lan- guage, Eric Lenneberg (1967) hypothesized that human language acquisition was an example of biologically constrained learning, and that it was normally acquired during a critical period, beginning early in life and ending at puberty.
What is the critical period hypothesis in Secret of the Wild child?
The critical period hypothesis for language acquisition was popularized by neurologist Eric Lenneberg. The hypothesis suggests that if an individual is not exposed to language during a specific period in their childhood then they will have great difficulties acquiring language later in life (Redmond, 1993).

Acquiring first language after this period is much more difficult and will never reach the perfect status of language acquired during the CP.
What do you think that Genie's story tells us about language development with regards to critical periods of learning language?
Genie failed to learn any kind of grammar. According to Chomsky this is what distinguishes the language of humans from the of animals. Genie could not grasp the difference between various pronouns or between active and passive verbs. In that sense she appeared to have passed the critical period.
What is Lenneberg theory?
Lenneberg (1967) asserts that if no language is learned by puberty, it cannot be learned in a normal, functional sense. He also supports Penfield and Roberts' (1959) proposal of neurological mechanisms responsible for maturational change in language learning abilities.
Is Genie still alive?
Her current whereabouts are uncertain, although she is believed to be living in the care of the state of California. Psychologists and linguists continue to discuss her, and there is considerable academic and media interest in her development and the research team's methods.
Is the critical period hypothesis true?
The critical period hypothesis says that there is a period of growth in which full native competence is possible when acquiring a language. This period is from early childhood to adolescence. The critical period hypothesis has implications for teachers and learning programmes, but it is not universally accepted.
What is critical period example?
The best known example of a critical period in animal development is that young ducks will become imprinted on any moving object in their immediate environment at approximately 15 h after hatching. If they do not experience a moving object during this critical period they will fail to become imprinted at all7.
What was Chomsky theory of language?
Chomsky believed that language is innate, or in other words, we are born with a capacity for language. Language rules are influenced by experience and learning, but the capacity for language itself exists with or without environmental influences.
What are hypotheses?
A hypothesis is an assumption, an idea that is proposed for the sake of argument so that it can be tested to see if it might be true. In the scientific method, the hypothesis is constructed before any applicable research has been done, apart from a basic background review.
What did you learn from Genie's case?
Despite the tragedy that surrounds the case of Genie, her case teaches us an important lesson about language abilities. Telling a story (not necessarily in a grammatical way or even by using words) as well as understanding language are very different from being able to produce grammatical sentences in a language.
Why was Genie hoarding items?
Genie was hoarding various objects such as books. She seemed to be developing a sense of self. A month later, when James Kent was leaving after one of their sessions, she held his hand in order to stop him. She seemed to be developing friendships with some of her adult helpers.
Did Genie learn speak?
Linguists ultimately concluded that because Genie had not learned a first language before the critical period had ended, she was unable to fully acquire a language. Furthermore, despite the clear improvements in her conversational competence it remained very low, and her vocalizations remained highly atypical.
What is genies real name?
Genie is the name used for a feral child discovered by California authorities on November 4, 1970 in the Los Angeles suburb of Arcadia. Her real name is Susan Wiley. She was born in April of 1957 and was the fourth (and second surviving) child to unstable parents, Irene and Clark Wiley.
How old was Genie Wiley when she was found?
The case of Genie Wiley came to light on November 4, 1970. Genie was discovered by a social worker when her mother, who was partially blind, went to apply for social services. Genie had been isolated in a small room starting at the age of 20 months until her discovery at 13 years and 9 months old.
What question did Genie's sleep study raise that puzzled the scientists for years?
The sleep studies raised a question that would puzzle the Genie team for years. Was Genie brain damaged from her years of abuse, or had she been retarded from birth? When Genie was a baby, her father apparently decided she was retarded. He insisted on keeping her isolated because of that.
What are critical and sensitive periods?
Sensitive periods generally refer to a limited time window in development during which the effects of experience on the brain are unusually strong, whereas a critical period is defined as a special class of sensitive periods where behaviors and their neural substrates do not develop normally if appropriate stimulation ...
What are critical periods in child development?
Children's brains develop in spurts called critical periods. The first occurs around age 2, with a second one occurring during adolescence. At the start of these periods, the number of connections (synapses) between brain cells (neurons) doubles. Two-year-olds have twice as many synapses as adults.
What is critical period linguistics?
A critical period is a bounded maturational span during which experiential factors interact with biological mechanisms to determine neurocognitive and behavioral outcomes. In humans, the construct of critical period (CP) is commonly applied to first-language (L1) and second-language (L2) development.
What is the critical period for language development?
According to Lenneberg's theory, natural acquisition of (a first or a second) language from mere exposure occurs during a critical period that begins at the age of two years and ends in puberty.
What does Genie's case show us about brain development?
Genie's case illustrates that the brain has critical periods of development and if these periods are missed, the individual is unlikely to develop normally in those areas of life. Once a child has reached the age of ten, their brains begin to reduce some of the connections between brain cells.
Who was James Kent What was his involvement in Genie's case?
At first psychologist James Kent became a father figure. He had argued unsuccessfully that Genie should not be separated from her mother, the one emotional attachment in the child's life. Soon, Jean Butler, Genie's nursery school teacher while in the UCLA study, took the child under her wing.
