The tragic case of feral child Genie provides a unique perspective on the roles of socialization and physiology in language acquisition during the critical period. After 11 years of isolation and abuse Genie was discovered possessing no known language, having already passed what was theorized to be the critical period. Through examining Genie’s diagnosed mental retardation and dichotic testing, we can draw conclusions from her physical abuse and social isolation as it pertains to language development during the critical period. Using the example of Genie’s stalled linguistic development, her language acquisition compared to both normal children and late learners of American sign language (ASL), the role of exposure and socialization and brain lateralization, this paper will demonstrate support of the theory of critical period for language Eric Lenneberg was the first to propose there existed a critical period to learn a first or native language that was between that began around two and ended with the onset of puberty around thirteen years old. Lenneberg theorized that language acquisition was not possible before age two because of a lack of maturation, while post-puberty acquisition is inhibited by a loss of cerebral placicity occuring when the cerebral dominance of the language function is complete, happening around the time of puberty (Kraschen). “Children deprived of language during this critical period show atypical patterns of brain lateralization” (intro to language) Lenneberg argued that lateralization of the brain during this critical period is key to language acquisition. “The human brain is primed to develop language in specific areas of the left hemisphere but the normal process of brain specialization depends on ear... ... middle of paper ... ...d, lateralization may be involved in a different way, the left hemisphere needs to be stimulated during the critical period, if this doesn’t occur then language acquisition becomes dependent on other cortical areas, namely the right hemisphere and as a result will produce less effective results never achieving the full language acquisition that would be possible prior to lateralization. (Krashen) Genie’s case demonstrates that although it is possible with extensive training to acquire some language after the critical period, a mastery of language after this period is not possible. Aspects such as vocabulary and certain conversational skills (textbook) are possible but the underlying grammar Genie’s lack of lateralization highlights the relationship between language and lateralization although it is unclear language input is a prerequisite for language acquisition.
There’s a long-standing argument that most people resort to when discussing whether or not children are better suited to acquire a language over adults. The “critical period hypothesis” argues, “that children are superior to adults in learning second languages because their brains are more flexible.” (McLaughlin 2) This argument is true to some extent, however, experimental research has found that adolescents and adults are able to acquire languages better based on their controlled environment. Children, on the other hand, are better able to grasp a better understanding of the pronunciation of languages compared to adults. (McLaughlin
I watched the documentary “Secret of the Wild Child”, on a girl who was in isolation from birth to thirteen years old. Her name was Genie and is referred to as a feral child. This means she was without human contact from a young age, and has no experience of human care, social behavior, and, of the human language. Feral children are often known as being raised as animals and therefore imitating their behaviors. However, a child who is severely neglected is also considered a feral child. During the time she was discovered, around 1970, there was a major debate in the field of psychology. The famous nature verses nurture argument, meaning does genetics play a greater role in development or does one’s environment. In the case of Genie, the real focus was on her language development and deciphering if there was a critical age to learn a language.

After Lenneberg's (1967) advanced analyses and interpretation of critical period in regards to first language acquisition, many researchers began to relate and study age issue in second language acquisition. In this area of study, Johnson and Newport (1989) is among the most prominent and leading studies which tries to seek evidence to test the Critical Period Hypothesis (CPH) in second language (L2) acquisition. This study aims to find identifying answers to the question of age-related effects on the proficiency for languages learned prior the puberty.
When children are born they have no concept of what a mother and father are, but they understand who they are and as the grow older they are able to connect those words mother and father to a person. Many behaviors and characteristics are resulted from learning. Albert Bandura tested a social experiment where a child watched another person act aggressively, they child then mimicked this aggressive behavior. This conditioning all leads to nurturing. Nurturing a person and conditioning them through actions and language can lead them to be anything, even if they have a genetic nature. Genie, through careful study and teaching was able to learn certain words and know the difference between the color black and white. She could use simple signs to get people to understand what she wanted. Prior to her teaching, she knew nothing of how to communicate, but due to a nurturing environment she was able to connect to the people around her. The critical period of a person's life comes when they are at infancy. This is the time when children learn the simple words of whatever language they are being taught. Studies have shown that if you want your child to be bilingual, the best way to teach them is when they are young, because at this point they are in the early stages of learning a language, and they are able to adapt much more quickly to this language then when they get older. The critical period of a child again falls under nurture, as it is up to the parents to nurture their child by teaching them the language they need to know to be successful. Language doesn't come in a your genetic nature, it comes from your parents teaching. While many believe that one can only learn a language in the critical period, it is disproven in A Genie and millions of other. Genie was able to form words and half decent
... (p. 116). In her article, “Babies Prove Sound Learners,” Sohn (2008), states, “Such studies show that, up to about 6 months of age, babies can recognize all the sounds that make up all the languages in the world” (para.24). B.K. Skinner suggest that the materialization of language is the result of imitation and reinforcement. According to Craig and Dunn (2010), “Language development is linked to cognitive development that, in turn, depends on the development of the brain, on physical and perceptual abilities, and on experiences. Biological and social factors also jointly influence the early development of emotion and personality” (p. 117). In her article, A natural history of early language experience. Hart (2000), states, “Talking is important for children, because complexity of what children say influences the complexity of other people’s response” (para. 1).
Child development language is a process by which children come to communicate and understand language during early childhood. This usually occurs from birth up to the age of five. The rate of development is usually fast during this period. However, the pace and age of language development vary greatly among children. Thus, the language development of a child is usually compared with norms rather than with other individual children. It is scientifically proven that development of girls language is usually at a faster rate than that of boys. (Berk, 2010) In other terms language development is also a crucial factor that reflects the growth and maturation of the brain. However, this development usually retards after the age of five making it very difficult for most children to continue learning language. There are two major types of language development in children. These include referential and expressive language development styles. In referential language development, children often first speak single words and then join the words together, first into –word sentences and then into th...

There are three main theories of child language acquisition; Cognitive Theory, Imitation and Positive Reinforcement, and Innateness of Certain Linguistic Features (Linguistics 201). All three theories offer a substantial amount of proof and experiments, but none of them have been proven entirely correct. The search for how children acquire their native language in such a short period of time has been studied for many centuries. In a changing world, it is difficult to pinpoint any definite specifics of language because of the diversity and modification throughout thousands of millions of years.
Wilder Penfield and Lamar Roberts first introduced the idea that there is a “critical period” for learning language in 1959. This critical period is a biologically determined period referring to a period of time when learning/acquiring a language is relatively easy and typically meets with a high degree of success. German linguist Eric Lenneberg further highlights Roberts and Penfield’s findings and postulated the Critical Period Hypothesis in 1967. According to the Critical Period Hypothesis (CPH), certain biological events related to language development can only happen in the critical period. During this time, the brain possesses a degree of flexibility (ability and ease of learning a language) and becomes lateralized (assignment of language functions becomes concrete – either in the left or right hemisphere) (Marinova-Todd, S; Marshall, D & Snow, C. 2000 9-10). This critical period lasts from childhood through the onset of puberty (usually at around 12 years of age). Once this period is over, it is more difficult to learn a language because language functions in the brain have become concrete. This hypothesis can be seen with the case of Genie, a woman who was isolated from human interaction and language up to the age of 13. By the time she was rescued, she was well after the critical period for language acquisition, and as such, she did not have a full command of the English language. Had she been rescued before the age of 13, she may have had more linguistic capability. However, this accounts for firs...
The study of language development, one of the most fascinating human achievements, has a long and rich history, extending over thousands of years (Chomsky, 2000). As the nature-versus-nurture argument is inevitable to arise whenever human behaviors are discussed, it is not surprising that language experts have debated the relative influences of genetics and the environment on language development (Hulit & Howard, 2002). Among the various proposals concerning the mechanisms involved in acquiring a language, two opposing theoretical positions, the behaviorist and the nativist, are the most prominent and influential ones (Ayoun, 2003; Garton & Pratt, 1998; Owens, 2001). Due to the indefinite explanation of the exact process, the continuous interest of the inquiring people, and the sheer significance of the precise result, the controversy remains ongoing and popular. In view of the more obvious limitations of the behaviorist interpretation and the prevailing contributions of the nativist interpretation, the latter one is more rational to accept.

Further in this term-paper I am going to describe the stages in child language acquistion starting from the very birth of an infant till the onset of puberty.
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). I believe the two “wild children” cases of Genie and Victor provides evidence to support the critical period hypothesis. Genie’s case supports the hypothesis because although she developed a vocabulary and despite all of her intense therapy sessions, she still was not able to create meaningful and grammatically correct sentences (Garmon, 1994). Genie’s inability to create real sentences may indicate that she endured the extreme deprivation during her critical period and it prevented her from acquiring language. Victor’s case also supports the critical period hypothesis. The professionals in the documentary The Secret of The Wild Child stated: “While Victor knew how to read simple words, he never learned how to talk” (Garmon, 1994). This quote implicates that similar to Genie, Victor developed a vocabulary,
A linguist at the Massachusetts Institute of Technology named Chomsky, declared that we have the ability to learn language not only because somebody taught us, but also because we are born with the principles of language in our genes. Chomsky also said “We have language because of nature, not just nurture” (Everywhere Psychology, 2012). Chomsky was one of the people that believed Genie still had a chance to learn language since everybody is born with the ability to learn. A neuropsychologist named Eric Lenneberg, agreed with Chomsky about humans being born with the ability to learn a language as nature, but believed there is a deadline for learning language. Lenneberg believed that if a first language isn 't learned by puberty it could be too late. What Lenneberg proposed is called the "critical period hypothesis," (Everywhere Psychology,
